MIR spectra have been widely used for thermal imaging, molecule characterizations, and communications. MIR light source is the key component of MIR technologies. Among them, MIR light-emitting diodes (LED) show advantages of narrow linewidth, low power consumption and portability. Since the rediscovery of thin-film BP in 2014, it has received much attention due to its unique properties, such as in-plane anisotropy, high carrier mobility, and tunable band gap, etc., making BP a promising material for applications in electronics and optoelectronics.

NASA used satellite data to create an animation of Fay's development and progression over the past few days, showing how the storm organized into a tropical storm. Additionally, NASA's Aqua satellite used infrared light to find the location of the strongest storms in Tropical Storm Fay occurring in the northeastern quadrant of the storm, mostly over the Atlantic Ocean.
NASA's Aqua satellite revealed better organization and colder cloud top temperatures in Tropical Storm Cristina, indications that the storm was strengthening.
On July 10 at 4:35 a.m. EDT (0835 UTC), the MODIS instrument aboard NASA's Aqua satellite analyzed Tropical Storm Cristina's cloud tops in infrared light. Infrared data provides temperature information, and the strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
RMIT-UNSW collaboration applies liquid-metal synthesis to piezoelectrics, advancing future flexible, wearable electronics, and biosensors drawing their power from the body's movements.
Materials such as atomically-thin tin-monosulfide (SnS) are predicted to exhibit strong piezoelectric properties, converting mechanical forces or movement into electrical energy.
This property, along with their inherent flexibility, makes them likely candidates for developing flexible nanogenerators that could be used in wearable electronics or internal, self-powered biosensors.
An ancient European volcanic region may pose both a greater long-term volcanic risk and seismic risk to northwestern Europe than scientists had realized, geophysicists report in a study in the Geophysical Journal International.
The emergence of COVID-19 is a powerful reminder of how unchecked wildlife trade can lead to the spillover spread of viruses between wildlife and humans. Understanding that wholesale bans on trade can affect community livelihoods and food security, the pandemic underscores the need for widespread pathogen screening and monitoring to better understand, predict and contain outbreaks in wildlife and humans.
Acute myeloid leukemia (AML) is a heterogeneous disease which usual treatment is very aggressive and produces severe side effects to the patients. In the search for a new and more effective drug, researchers from the CIBER for Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN) have demonstrated the efficacy of a new nanoconjugate, designed in house, that blocks dissemination of leukemic cells in animal models of acute myeloid leukemia.
A PhD student has produced the first digital reconstruction of the skull of a gigantic dormouse, which roamed the island of Sicily around two million years ago.
In a new study, the student from Hull York Medical School, has digitally pieced together fossilised fragments from five giant dormouse skulls to reconstruct the first known complete skull of the species.
The researchers estimate that the enormous long-extinct rodent was roughly the size of a cat, making it the largest species of dormouse ever identified.
Lightning is a spectacular natural phenomenon and the fascination with thunderstorms and lightning is a long-standing one. Today, lightning is known to be closely associated with the electrification and discharge of thunderstorms. Different types of thunderstorms correspond to different lightning characteristics and charge structures. But what are the characteristics of lightning in different types of thunderstorms?
Natural killer (NK) cells, a type of immune cell, are known to limit metastasis by inducing the death of cancer cells. But metastases still form in patients, so there must be ways for cancer cells to escape.
Curtin University researchers have discovered a new way to more accurately analyse microscopic samples by essentially making them 'glow in the dark', through the use of chemically luminescent molecules.
Lead researcher Dr Yan Vogel from the School of Molecular and Life Sciences said current methods of microscopic imaging rely on fluorescence, which means a light needs to be shining on the sample while it is being analysed. While this method is effective, it also has some drawbacks.
CHAMPAIGN, Ill. -- A study assessed the interaction of new and old relationship traumas among women three to 18 months after the birth of their child - one of the most challenging periods of their lives. The study found that new experiences of sexual, emotional and physical abuse at the hands of a romantic partner during this period are associated with increasing symptoms of trauma such as anxiety, depression, self-harm and sleep disorders. It also found that having experienced abuse in childhood appears to worsen the impact of current abuse on those symptoms.
Better understanding the science that underpins well-known techniques for developing quantum dots--tiny semiconducting nanocrystals--can help reduce the guesswork of current practices as material scientists use them to make better solar panels and digital displays.
Washington, July 9, 2020--Following U.S. students across five summers between grades 1 and 6, a little more than half (52 percent) experienced learning losses in all five summers, according to a large national study published today. Students in this group lost an average of 39 percent of their total school year gains during each summer. The study appeared in American Educational Research Journal, a peer-reviewed publication of the American Educational Research Association.
