Published Colloids get creative to pave the way for next generation photonics
(via sciencedaily.com) Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light.
Published Virtual reality games can be used as a tool in personnel assessment
(via sciencedaily.com) Fast gamers are more intelligent: Intelligence can be predicted through virtual reality games.
Published Electrocatalysis under the atomic force microscope
(via sciencedaily.com) A further development in atomic force microscopy now makes it possible to simultaneously image the height profile of nanometer-fine structures as well as the electric current and the frictional force at solid-liquid interfaces. A team has succeeded in analyzing electrocatalytically active materials and gaining insights that will help optimize catalysts. The method is also potentially suitable for studying processes on battery electrodes, in photocatalysis or on active biomaterials.
Published Hitting nuclei with light may create fluid primordial matter
(via sciencedaily.com) A new analysis supports the idea that photons colliding with heavy ions create a fluid of 'strongly interacting' particles. The results indicate that photon-heavy ion collisions can create a strongly interacting fluid that responds to the initial collision geometry and that these collisions can form a quark-gluon plasma. These findings will help guide future experiments at the planned Electron-Ion Collider.
Published A surprising way to trap a microparticle
(via sciencedaily.com) New study finds obstacles can trap rolling microparticles in fluid. Through simulations and experiments, physicists attribute the trapping effect to stagnant pockets of fluid, created by hydrodynamics. Random motions of the molecules within the fluid then 'kick' the microroller into a stagnant pocket, effectively trapping it.
Published Artificial intelligence (AI) reconstructs motion sequences of humans and animals
(via sciencedaily.com) Imagine for a moment, that we are on a safari watching a giraffe graze. After looking away for a second, we then see the animal lower its head and sit down. But, we wonder, what happened in the meantime? Computer scientists have found a way to encode an animal's pose and appearance in order to show the intermediate motions that are statistically likely to have taken place.
Published Viable superconducting material created, say researchers
(via sciencedaily.com) Researchers report the creation of a superconducting material at both a temperature and pressure low enough for practical applications. In a new paper, the researchers describe a nitrogen-doped lutetium hydride that exhibits superconductivity at 69 degrees Fahrenheit and 10 kilobars (145,000 pounds per square inch, or psi) of pressure.
Published Enhancing at-home COVID tests with glow-in-the dark materials
(via sciencedaily.com) Researchers are using glow-in-the-dark materials to enhance and improve rapid COVID-19 home tests.
Published Controlling electric double layer dynamics for next generation all-solid-state batteries
(via sciencedaily.com) Development of all-solid-state batteries is crucial to achieve carbon neutrality. However, their high surface resistance causes these batteries to have low output, limiting their applications. To this end, researchers have employed a novel technique to investigate and modulate electric double layer dynamics at the solid/solid electrolyte interface. The researchers demonstrate unprecedented control of response speed by over two orders of magnitude, a major steppingstone towards realization of commercial all-solid-state batteries.
Published The positive outlooks of studying negatively-charged chiral molecules
(via sciencedaily.com) The ability to distinguish two chiral enantiomers is an essential analytical capability for chemical industries including pharmaceutical companies, flavor/odor engineering and forensic science. A new wave of chiral optical methods have shown significant improvements in chiral sensitivity, compared to their predecessors, leading to potential analytical advantages for chiral discrimination.
Published Catalyst purifies herbicide-tainted water and produces hydrogen
(via sciencedaily.com) Researchers have developed a dual-purpose catalyst that purifies herbicide-tainted water while also producing hydrogen.
Published Researchers propose a simple, inexpensive approach to fabricating carbon nanotube wiring on plastic films
(via sciencedaily.com) Researchers have developed an inexpensive method for fabricating multi-walled carbon nanotubes (MWNTs) on a plastic film. The proposed method is simple, can be applied under ambient conditions, reuses MWNTs, and produces flexible wires of tunable resistances without requiring additional steps. It eliminates several drawbacks of current fabrication methods, making it useful for large-scale manufacturing of carbon wiring for flexible all-carbon devices.
Published Coral-friendly sunscreen provides better UV protection than existing options
(via sciencedaily.com) Researchers have developed a prototype for coral-reef-friendly sunscreens by using polymerization to create large molecules that still block UV radiation but are too big to penetrate our skin, coral, and algae. The polymeric UV filter was more effective at preventing sunburn in mice than existing sunscreens.
Published Quantum chemistry: Molecules caught tunneling
(via sciencedaily.com) Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in theory. The scientists provide an important reference for this fundamental effect in chemistry. It is the slowest reaction with charged particles ever observed.
Published Artificial Intelligence from a psychologist's point of view
(via sciencedaily.com) Researchers test cognitive abilities of the language model GPT-3.
Published Sustainable process for the production of vanillin from lignin makes further progress
(via sciencedaily.com) The demand for vanillin vastly outstrips the natural resources of this flavoring agent. A chemical process is thus used to produce the required large quantities of vanillin from petroleum, which is far less expensive than obtaining the substance from fermented genuine vanilla pods. Another alternative is to make vanillin from lignin, a waste product of the wood pulping industry. A team has now managed to further enhance their method of electrochemical production of vanillin from lignin in that they employ a 'green' oxidation method for this purpose.
Published New purification method could make protein drugs cheaper
(via sciencedaily.com) Original source Engineers devised a way to purify protein drugs during manufacturing. Their approach, which uses nanoparticles to rapidly crystallize proteins, could help make protein drugs more affordable and accessible, especially in developing countries.
Published Will future computers run on human brain cells?
(via sciencedaily.com) A 'biocomputer' powered by human brain cells could be developed within our lifetime, according to researchers who expect such technology to exponentially expand the capabilities of modern computing and create novel fields of study.

(via sciencedaily.com) A tiny robot that could one day help doctors perform surgery was inspired by the incredible gripping ability of geckos and the efficient locomotion of inchworms.
Published New superacid converts harmful compounds into sustainable chemicals
(via sciencedaily.com) Researchers have succeeded in producing very special catalysts, known as 'Lewis superacids', which can be used to break strong chemical bonds and speed up reactions. The production of these substances has, until now, proven extremely difficult. The chemists' discovery enables non-biodegradable fluorinated hydrocarbons, similar to Teflon, and possibly even climate-damaging greenhouse gases, such as sulphur hexafluoride, to be converted back into sustainable chemicals.
