Induced-fit adsorbent for acetylene
We often say that a substrate fits into its enzyme like a key in a lock, but this metaphor is imperfect. Substrate binding can also change the lock (the structure of the enzyme) to induce a perfect fit. In the journal Angewandte Chemie, an internatio.....»»
Impact of film thickness in laser-induced periodic structures on amorphous Si films
Since the scientists at Bell Labs invented the world's first transistor in December 1947, a revolution in microelectronics technology has profoundly affected lifestyles worldwide. As electronics get smaller and smaller, it is a challenge to find an e.....»»
Transplantation of genome-edited iPS cells delivers therapeutic molecules in vivo
Induced pluripotent stem (iPS) cells have a great impact on biology and medicine, and they are expected to improve regenerative medicine. Since 2014, when a sheet of retinal pigment epithelial cells derived from iPS cells was transplanted into patien.....»»
New silica-based adsorbent developed for selective separation of radioactive strontium from acidic medium
Prof. Huang Qunying's team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a novel inorganic silica-based adsorbent for the highly selective separation of strontium from acidic medium. The results were p.....»»
Research team reports on discovery of grain-interior planar defects induced by heteroatom monolayer
In collaboration with the Institute of Physics at the Chinese Academy of Sciences (IPCAS), researchers from Beijing University of Technology (BJUT) have discovered a new type of grain-interior planar defect in a ceramic phase in TiC doped cemented tu.....»»
Research shows more than 90% of global aquaculture faces substantial risk from environmental change
Many of the world's largest aquatic food producers are highly vulnerable to human-induced environmental change, with some of the highest-risk countries in Asia, Latin America and Africa demonstrating the lowest capacity for adaptation, a landmark stu.....»»
Physicists develop a novel quantum theory of light-induced matter
A team led by a physicist from City University of Hong Kong (CityU) recently developed a new quantum theory that explains the "light-induced phase" of matter and predicts its novel functionalities. The new theory has the potential to revolutionize th.....»»
A new adsorbent for removing radioactive cesium ions from nuclear wastewater
Nuclear power is typically considered a cleaner way of generating power compared to fossil fuels. It does not release air pollutants and greenhouse gasses like carbon dioxide as by-products. However, it creates radiotoxic waste that needs proper trea.....»»
Cybercriminals return to business as usual in a post-pandemic world
After two years of pandemic-induced disruption, 2022 was a return to business as usual for the world’s cybercriminals, according to Proofpoint. As COVID-19 medical and economic programs began to wind down, attackers had to find new ways to make a l.....»»
Novel single crystals show promising electric field control of magnetism
A research team led by associate Prof. Yin Lihua from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has demonstrated a clear control of magnetism at low electric fields (E) at room temperature. The E-induced phase transf.....»»
Unlocking early Earth chemistry: Salt-induced changes in polyester microdroplet structure
Billions of years ago, Earth was an extremely hostile planet with active volcanoes, a harsh atmosphere, and no life. This prebiotic Earth, however, was filled with a wide array of abiotic organic molecules derived from its early environment, which un.....»»
Breakdown spectroscopy induced by nonlinear interactions of femtosecond laser filaments
The research team of the State Key Laboratory of Precision Spectroscopy at East China Normal University has made significant progress in the field of ultra-fast laser-induced breakdown spectroscopy technology......»»
Ultrafast X-ray spectroscopy: Watching molecules relax in real time
Designing the next generation of efficient energy conversion devices for powering our electronics and heating our homes requires a detailed understanding of how molecules move and vibrate while undergoing light-induced chemical reactions......»»
Study: Information about climate-induced migration spurs negative attitudes about immigrants
Reading about climate-induced immigration prompted negative, nativist attitudes among people toward the affected migrants—an unintended, perhaps even paradoxical effect of many delivering the original messages, according to researchers at the Unive.....»»
Study tracks how newcomers may change ecosystem functions
In a study tracking climate-induced changes in the distribution of animals and their effects on ecosystem functions, North Carolina State University researchers show that resident species can continue managing some important ecological processes desp.....»»
The impact of thermal drawdown-induced alterations in rock thermal properties on heat recovery
Geothermal energy, found in subsurface hot dry rocks, is a viable option instead of fossil fuels. Enhanced geothermal systems (EGS) enable us to use the plentiful amounts of energy in the hot rocks. The optimization and risk management of this proces.....»»
Breakthrough in dynamical localization transitions and Berry curvature-induced transport
The way light moves around inside an optical microcavity provides an exciting opportunity to explore the connection between classical and quantum physics. This field of research is known as quantum chaos, and it has the potential to spawn many new te.....»»
Hertz results show revenue increase with strong rental car demand
Demand for rentals remains strong as more companies mandate work from office and people resume their travel plans after a long pandemic-induced hiatus......»»
Newly observed effect makes atoms transparent to certain frequencies of light
A newly discovered phenomenon dubbed "collectively induced transparency" (CIT) causes groups of atoms to abruptly stop reflecting light at specific frequencies......»»
Climate extremes and forest age mediate drought-induced forest mortality in northeast China
Drought-induced forest mortality is associated with climatic factors (e.g., high-temperature, precipitation deficit) and forest age, but may vary due to differences among tree species. However, a large-scale survey of forest mortality cannot usually.....»»
Hot electron electrochemistry with ultrafast laser pulses
Laser-induced electrochemical deposition of metals on metals relies possibly on thermal and defect generation effects. When semiconductor substrates are chosen, locally photogenerated electrons can reduce metal ions resulting in metallic surface stru.....»»
