Radiative cooling boosts solar cell voltage by as much as 25% - Physics World


Solar Cell Array - Photo Courtesy euromet.org

Cheap and simple radiative cooling technologies can significantly increase the performance and lifespan of concentrated photovoltaic systems, according to researchers in the US. They found that a simple radiative cooling structure can increase the voltage produced by the solar cells by around 25%. 

 It also reduced operating temperatures by as much as 36 °C and the scientist claim this could dramatically extend the lifetime of photovoltaic systems. Commercial silicon-based photovoltaic cells convert around 20% of solar irradiation that falls on them into electricity. 

Much of the rest is turned into heat, which must be effectively managed. “Photovoltaic efficiency and lifetimes both decrease as temperature goes up – especially in humid environments,” explains Peter Bermel, an engineer at Purdue University. “The loss in efficiency is fundamental to how photovoltaics work.” 

 The post Radiative cooling boosts solar cell voltage by as much as 25% appeared first on Physics World, where you can read the whole story.

On climate clock, it's parts per million, not minutes, that matter most

This is a re-post from Yale Climate Connections by Bud Ward As sentient but fallible human beings, we often are cautioned about excessively watching the clock.


Even on their worst days, we all know, they’re right at least twice daily.

Watching the clock has its rightful place in many practices. Take the various shot-clocks in basketball or the five-seconds in which to pass the ball in bounds, the service clock in pro tennis, the delay-of-game clock in football.

In the climate change policy context, the clock can be both enemy and friend. Who can forget how many times we’ve been warned – albeit with lots of leeway in varying from the original reference – about having “only 12 years” remaining in which to, as the story gets infinitely re-told and restated, save the world and all humanity?

There are clocks. And there are clocks. Some are said to speed along at warp speeds, and some seem never to advance at all. It’s all in who’s doing the watching and time-keeping. So beware.

Something now in vogue among many eager to see real action on addressing global warming is word that only about nine months remain to take serious action: That is, to address our fossil fuel gluttony. For purposes of discussion, let’s say that takes us through about the end of July 2021, give or take a smidge.

This current doomsday clock is fueled by 1) a preference for a preferred outcome in the presidential election now 28 days away; and 2) the notion that the first six months of any new administration is the period most ripe for major legislative action. So from the January 20, 2021, presidential inauguration date, go out about six months.

Lots of variables and unknown unknowns go into this thinking, of course, including primarily who is or is not elected and inaugurated come January 2021; and, of course, the importance of the winning candidate’s having, or not having, a supportive majority in both the Senate and the House to help move along priorities.

One need not think too hard to remember that the incoming Obama administration in 2009 had drawn just such a straight flush but then – whether rightly or wrongly – chose to advance a public health rather than an energy/climate agenda. Whether that in fact was or was not the “right” decision is at this point irrelevant.

Connecting Measurement Devices over TCP-IP

App Tip From Windmill Software

Online -- TCP/IP is a standard method for sending messages across a network. It is used on many networks including Internet and Ethernet.

It is a good idea when first connecting instruments to keep things as simple as possible. 


A direct connection between instrument and computer with no wider network connection seems sensible but it has some pitfalls.

  1. To connect your computer Ethernet port directly to the Instrument requires a special twisted cable. The cable used to connect your computer to a network hub will not work.
  2. If your computer uses a Dynamic IP Address then it cannot get an IP Address unless connected to a DHCP server. So in this arrangement won't work either.
  3. If the instrument uses a Dynamic IP Address it will not work unless your computer is configured as a DHCP server. Your computer will also need to perform the Name Server function to deal with such an instrument.
  4. Both computer and instrument will need to be on the same Subnet.

A direct connection is only easy if both computer and instrument use fixed IP Addresses on the same subnet and you have the correct cable.

The world's latest sea-level satellite

On Nov. 10, the world's latest Earth-observing satellite is scheduled to launch from Vandenberg Air Force Base in California. As a historic U.S.-European partnership. 

 The Sentinel-6 Michael Freilich spacecraft will begin a five-and-a-half-year prime mission to collect the most accurate data yet on global sea level and how our oceans are rising in response to climate change. 

The mission will also collect precise data of atmospheric temperature and humidity that will help improve weather forecasts and climate models.

Required Roof Conditions for Infrared Flat Roof Moisture Survey

From Jersey Infrared Consultants


The requirements listed below are based on current industry standards, including those published by ASTM, RCI and Infraspection Institute. Compromising on any of these requirements may adversely affect the results of the Infrared Flat Roof Moisture Survey.

Dry Roof Membrane: 

The roof membrane must be dry at Sunrise. Areas that had moisture at Sunrise may not have enough solar loading to show the necessary thermal patterns. Since an infrared imager cannot “see through water”, any areas with the presence of ice, snow, or standing water cannot be surveyed.

Solar Loading:

The day of the Survey should be a mostly sunny day, providing good solar loading. A general rule of thumb is if the roof surface or a nearby similar surface (i.e. parking lot, street or sidewalk) is warm to the touch, the roof will be warm.

Sea level mission will also act as a precision thermometer in space


When a satellite by the name of Sentinel-6 Michael Freilich launches this November, its primary focus will be to monitor sea level rise with extreme precision. But an instrument aboard the spacecraft will also provide atmospheric data that will improve weather forecasts, track hurricanes, and bolster climate models.

"Our fundamental goal with Sentinel-6 is to measure the oceans, but the more value we can add, the better," said Josh Willis, the mission's project scientist at NASA's Jet Propulsion Laboratory in Southern California. "It's not every day that we get to launch a satellite, so collecting more useful data about our oceans and atmosphere is a bonus."

A U.S.-European collaboration, Sentinel-6 Michael Freilich is actually one of two satellites that compose the Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission. The satellite's twin, Sentinel-6B, will launch in 2025 to take over for its predecessor. 

Together, the spacecraft will join TOPEX/Poseidon and the Jason series of satellites, which have been gathering precise sea level measurements for nearly three decades. Once in orbit, each Sentinel-6 satellite will collect sea level measurements down to the centimeter for 90% of the world's oceans.

Researchers develop smallest particle sensor in the world

 

GRAZ UNIVERSITY OF TECHNOLOGY











It is slightly smaller than two one-cent coins stacked on top of each other, is particularly energy-efficient due to its size, requires no maintenance and can be integrated in mobile devices. It is the smallest particle sensor in the world. 

With this 12 x 9 x 3 millimetre innovation, smartphones, smart watches or fitness wristbands can for the first time measure the quality of the ambient air in real time and sound the alarm in the event of increased fine dust values. 

Innovative implementation 

The sensor was developed by Paul Maierhofer as part of his dissertation at the Institute of Electrical Measurement and Sensor Systems at Graz University of Technology together with experts from the semiconductor manufacturer ams AG and with researchers from Silicon Austria Labs (SAL). The development was based on well-known methods of conventional measuring instruments as well as modern manufacturing and integration methods, which brought the project team together in an innovation process. 

The innovation is the miniaturization itself, as Maierhofer explains: "The sensor is right at the limit of what is physically and technically feasible and involves a lot of tricks to function at this size." 

Adapting behaviour to ambient air 

The immense social benefit of this new innovative particle sensor is obvious. According to a study by the European Environment Agency (EEA), over 400,000 people die prematurely every year in Europe alone as a result of particulate matter pollution. 

With the help of wearables equipped with the new particle sensor, each and every individual can monitor the ambient air and react immediately in the case of health-endangering fine dust values. "For example, by avoiding particularly polluted routes when jogging or on the daily commute to work," says Alexander Bergmann, head of the Institute of Electrical Measurement and Sensor Systems at TU Graz and doctoral supervisor of Paul Maierhofer. 

Improving air quality 

Not only in wearables, the sensor can also be integrated in local applications - both in the home and outdoors - and thus provides an unprecedented variety of measured values. 

Bergmann is convinced that this represents a break from the past in air quality monitoring: "Close-meshed and comprehensive monitoring of air quality has so far failed due to the size, complexity and cost of currently available measuring sensors. Our particle sensor fills a gap here." 

The data obtained can serve as a basis for further regulatory measures and raise public awareness of the particulate matter problem. The series production aimed at by semiconductor manufacturer ams is intended to achieve a price that is significantly lower than the currently available sensors. 

This research is anchored in the Fields of Expertise "Mobility & Production" and "Sustainable Systems", two of five strategic focal areas of Graz University of Technology. 
 
The Institute of Electrical Measurement and Sensor Systems at TU Graz is one of the world's leading institutions in the field of particle measurement. At EU level, researchers from the Institute are involved in the Horizon2020 projects CARES (for more information, see TU Graz News), DownToTen (News report from January 2020) and SENSmat (http://www.sensmat.eu).

Accurate Fever Scanning with Infrared Forehead Thermometers: Issues, Solutions and How to Calibrate

 FlukeCal Publishes Helpful Article Online



Because of the COVID-19 pandemic, there is a lot of interest in measuring human body temperature. I’m sure you’ve seen articles or you had your own temperature measured as you entered a public place like a store or medical building. 

Most of the interest in measuring human body temperature is in the area of non-contact or infrared (IR) temperature measurement. Infrared measurements are ideal for this fever screening because making the measurement only takes a few milliseconds, and you don’t have to touch the person or object you are measuring, which helps prevent further spread of CoronaVirus. 

Article overview 

 We know a lot about radiation thermometry here at Fluke Calibration. We manufacture some of the best IR calibration standards in the world and our experts are recognized in the metrology community. For example, Frank Liebmann is a recognized expert in the field, and he has contributed many technical articles and scientific papers on this subject.

 Frank has trained hundreds from around the world on proper methods for performing IR temperature measurements and calibrations. Thanks to Frank and other Fluke IR experts, we can provide answers for the challenging questions you may have.

 In this post I’m going to answer some basic questions about IR thermometers for human fever screening, such as how they measure, some of the challenges with using them for human body temperature measurement, and how to check the accuracy to know that an instrument is living up to its claimed specifications. 

 We’re also working on more technical content which will be published at a later date. If you are interested in being informed about that, please sign up for our email list.

Google’s Search Preference Menu Eliminates DuckDuckGo

 

The sixth in a series of posts about search preference menus.
  • The Q4 2020 results of Google’s search preference menu auction have been released and, as we predicted, DuckDuckGo has been eliminated in most countries.
  • This EU antitrust remedy is only serving to further strengthen Google’s dominance in mobile search by boxing out alternative search engines that consumers want to use and, for those search engines that remain, taking most of their profits from the preference menu.
  • The auction model is fundamentally flawed and must be replaced.

An Antitrust Remedy that Hurts Competition As explained in this series, we believe search preference menus — ones that change all search defaults and include the most common Google alternatives — can enable consumers to easily express their search preferences and significantly increase competition in the search market. 

Our most recent large-sample user testing shows that when a search preference menu is designed properly, then Google’s search mobile market share could immediately drop by around 20% (with potentially greater market change shift over time). However, Google’s current search preference menu in the EU is not properly designed, evidenced by the just released Q4 2020 auction results, listing which search engines will appear on the menu. DuckDuckGo, despite being the Google alternative that consumers most want to select, will no longer appear in most countries.  

As a result, many EU residents buying a new Android device will no longer have an easy way to adopt a private search engine. The central problem with Google’s search preference menu is that it is a pay-to-play auction in which only the highest bidders are on the menu. This auction format incentivizes bidders to bid what they can expect to profit per user selection. 

The long-term result is that the participating Google alternatives must give most of their preference menu profits to Google! Google’s auction further incentivizes search engines to be worse on privacy, to increase ads, and to not donate to good causes, because, if they do those things, then they could afford to bid higher. 

  Why Was DuckDuckGo Eliminated? 

 Despite DuckDuckGo being robustly profitable since 2014, we have been priced out of this auction because we choose to not maximize our profits by exploiting our users. In practical terms, this means our commitment to privacy and a cleaner search experience translates into less money per search. This means we must bid less relative to other, profit-maximizing companies. We predicted this outcome but chose to participate as long as we could since offering consumers an easy way to get simple privacy protection is more important than a boycott. We weren’t eliminated sooner for two reasons. First, prices were temporarily depressed due to less bidders because we believe not all eligible companies submitted the initial paperwork on time to participate in early rounds. Second, we didn't have adequate data on auction outcomes and how it impacted our business until this round. With this information, we bid what is long-term sustainable, and we were eliminated. 

  How to Make a Preference Menu that Works 

 There is a better way. Our series of posts on search preference menus explains in detail how to design one that actually empowers consumers and increases search competition. In our proposal, there is no auction. Alternative search engines with the most market share in each market are shown on the first screen, randomly ordered. The remaining alternative search engines are available by scrolling, also randomly ordered. Our research shows that such a preference menu can be a great remedy. The European Commission should take action now and require Google to overhaul its preference menu design. The current remedy is not a remedy at all – it is fundamentally rigged by Google to benefit Google. The Commission has said they have been waiting on data to act: such data is now available. To expedite this process, we are sending the Commission our data that demonstrates exactly how the current process inevitably eliminates DuckDuckGo.

New Hubble Data Suggests There is an Ingredient Missing from Current Dark Matter Theories

 




Observations by the NASA/ESA Hubble Space Telescope and the European Southern Observatory’s Very Large Telescope (VLT) in Chile have found that something is missing.

This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters. 

The new findings indicate that some small-scale concentrations of dark matter produce lensing effects that are 10 times stronger than expected.

The release, images and videos are available on:
https://www.spacetelescope.org/news/heic2016/

Dark matter is the invisible glue that keeps stars, dust, and gas together in a galaxy. This mysterious substance makes up the bulk of a galaxy's mass and forms the foundation of our Universe's large-scale structure. Because dark matter does not emit, absorb, or reflect light, its presence is only known through its gravitational pull on visible matter in space. Astronomers and physicists are still trying to pin down what it is.

Galaxy clusters, the most massive and recently assembled structures in the Universe, are also the largest repositories of dark matter. Clusters are composed of individual member galaxies that are held together largely by the gravity of dark matter.

Mystery of the Dimming of Betelgeuse

 

New observations by the NASA/ESA Hubble Space Telescope suggest that the unexpected dimming of the supergiant star Betelgeuse was most likely caused by an immense amount of hot material ejected into space, forming a dust cloud that blocked starlight coming from Betelgeuse’s surface.

Betelgeuse is an aging, red supergiant star that has swelled in size as a result of complex, evolving changes in the nuclear fusion processes in its core. The star is so large that if it replaced the Sun at the centre of our Solar System, its outer surface would extend past the orbit of Jupiter. 

The unprecedented phenomenon of Betelgeuse’s great dimming, eventually noticeable to even the naked eye, began in October 2019. By mid-February 2020, the brightness of this monster star had dropped by more than a factor of three.

First Observation of a Total Lunar Eclipse By a Space Telescope

 

Taking advantage of a total lunar eclipse, astronomers using the NASA/ESA Hubble Space Telescope have detected ozone in Earth’s atmosphere. This method serves as a proxy for how they will observe Earth-like planets around other stars in the search for life. 

This is the first time a total lunar eclipse was captured from a space telescope and the first time such an eclipse has been studied in ultraviolet wavelengths.

In a new study, Hubble did not look at Earth directly. Instead, astronomers used the Moon as a mirror that reflects the sunlight that has been filtered through Earth’s atmosphere. 

Using a space telescope for eclipse observations is cleaner than ground-based studies because the data is not contaminated by looking through Earth’s atmosphere.

Lake Shore Acquires Janis Research Laboratory Cryogenics Business


Lake Shore Cryotronics today announced the acquisition of Janis Research’s Laboratory Cryogenics business — a move that unites two of the world’s leading providers of cryogenic and material characterization solutions for low-temperature research. 

The acquisition of the Woburn, MA, based business enables Lake Shore to now offer Janis Research liquid nitrogen (LN2), liquid helium (LHe), and closed-cycle refrigerator (cryogen-free) cryostats, LHe and cryogen-free superconducting magnet systems, cryogenic and cryogen-free probe stations, and various lab cooling systems. 

This acquisition by Lake Shore does not include the Janis dilution refrigerator or He-3 ultra-low temperature (ULT) system product lines. These will be available from JanisULT, a separate, privately-owned company.  

“Janis is an ideal fit for Lake Shore,” said Michael Swartz, Lake Shore Cryotronics President and CEO. “They’re highly knowledgeable about the needs of scientists and others working in low-temperature physics and early-stage materials research, and together, we can offer a more complete portfolio of product solutions. We are impressed with the design to customer requirement capabilities of Janis Research.” 

Founded in 1961, Janis Research began as a manufacturer of LHe transfer lines and soon expanded its product offering to include cryogenic research equipment, ranging from simple LHe storage Dewars to sophisticated superconducting magnet and low-temperature systems.

Scott Azer, Janis Research’s VP of Business Development, said, “The Janis team is thrilled to become part of a world-class organization like Lake Shore. We see many synergistic product opportunities ahead, combining Lake Shore’s expertise in instrumentation, applications, and system engineering with Janis' strength in cryogenic system design and fabrication. We look forward to serving the scientific community even more effectively than before, as members of the Lake Shore family.”

Janis Research will maintain product development, engineering, manufacturing, and product shipping operations in Woburn, MA.

Far-UVC light (222 nm) and human coronaviruses

In a June 24th article in Nature Scientific Reports by 

“Far-UVC light (222 nm) efficiently and safely inactivates airborne human coronaviruses”


...we have shown that very low doses of far-UVC light efficiently kill airborne human coronaviruses carried by aerosols. A dose as low as 1.2 to 1.7 mJ/cm2 of 222-nm light inactivates 99.9% of the airborne human coronavirus tested from both genera beta and alpha, respectively. As all human coronaviruses have similar genomic size, a key determinant of radiation sensitivity27, it is likely that far-UVC light will show comparable inactivation efficiency against other human coronaviruses, including SARS-CoV-2.

Together with previous safety studies12,13,14,15,16,17,18 and our earlier studies with aerosolized influenza A (H1N1)23, these results suggest the utility of continuous low-dose-rate far-UVC light in occupied indoor public locations such as hospitals, transportation vehicles, restaurants, airports and schools, potentially representing a safe and inexpensive tool to reduce the spread of airborne-mediated viruses. While staying within the current regulatory dose limits, low-dose-rate far-UVC exposure can potentially safely provide a major reduction in the ambient level of airborne coronaviruses including SARS-CoV-2.

Temperature Calibrators for SAE AMS2750F Pyrometry

Has impact on the Metal Heat Treating Industry


The recent release of SAE AMS2750F Pyrometry by SAE International has impacted the Metal Heat Treating Industry by requiring upgrades to their temperature measurement and calibration instruments. The TEGAM Model 945A thermocouple calibrator meets the requirements in one convenient and portable instrument.

There are many changes in SAE AMS2750F of which you should be aware. It is a complete rewrite. 

One of the significant changes was the increased resolution of temperature instruments. It is now required that instruments measure to 0.1° of resolution throughout their entire range. This limits the choices as many digital thermometers only register 0.1° up to 999.9°. 

Many heat-treat processes operate above this temperature and the increased resolution is necessary to properly set and adjust ovens.

Increasing storage safety after mineral extraction

The water needs to go


water removal charts 
 When companies extract minerals from the ground, they are generally left with a liquid slurry made of fine particles and water - "tailings". This creates the problem of storage. 

Excess water in the tailings can lead to a disaster. For the tailings to be safely stored, the water needs to go. 

 Scientists from Australia's national science research agency, CSIRO, are investigating methods of more efficiently extracting the water, and are using Windmill software to measure the expulsion of liquid under different conditions.
