I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Avoiding food contamination with a durable coating for hard surfaces” A new study from the University of Missouri demonstrates that a durable coating—made from titanium dioxide—is capable of eliminating foodborne germs, such as salmonella and E. coli, and provides a preventative layer of protection against future cross-contamination on stainless steel food-contact surfaces. In the future,…
“#Light and nanoparticles against cancer” Figure 1. Chemical formula (left) and Pd…Pd interaction (right) in the crystal structure of Zhou’s new palladium complex. Credit: Leiden University Leiden Ph.D. student Xuequan Zhou has designed a new promising molecule that efficiently kills cancer cells, but does not harm healthy tissue. The trick: the drug is only active…
“#Predicting X-ray absorption spectra from graphs” A schematic showing the steps for training a machine learning model to predict an x-ray absorption (XAS) spectrum based on the known structure of a molecule. The molecule’s structure is represented as a graph, with atoms as nodes and chemical bonds as edges. This representation captures the connectivity of…

“#Low-cost catalyst helps turn seawater into fuel at scale” Credit: Pixabay/CC0 Public Domain The Navy’s quest to power its ships by converting seawater into fuel is one step nearer fruition. University of Rochester chemical engineers, in collaboration with researchers at the Naval Research Laboratory, the University of Pittsburgh, and OxEon Energy, have demonstrated that a…
“#New material mimics strength, toughness of mother of pearl” The iridescent nacre inside a Nautilus shell. Image: Wikipedia. In the summer, many people enjoy walks along the beach looking for seashells. Among the most prized are those that contain iridescent mother of pearl (also known as nacre) inside. But many beachcombers would be surprised to…
“#Bacteria with a metal diet discovered in dirty glassware” Manganese oxide nodules generated by the bacteria discovered by the Caltech team. The nodules are generally about 0.1 to 0.5 millimeters in diameter. Images are scanning electron micrographs with false colorization. Credit: Hang Yu/Caltech Caltech microbiologists have discovered bacteria that feed on manganese and use the…
“#Scientists discover heavy element chemistry can change at high pressures” Curium crystals with an orange glow, which the researchers used to monitor the changes in chemistry as they applied pressure. Credit: Thomas Albrecht-Schmitt / Nature New research shows that one of the heaviest known elements can be manipulated to a greater degree than previously thought,…
“#Running on empty: New affordable catalyst relies on nitrogen vacancies to produce ammonia” Nickel-loaded lanthanum nitride (LaN) enables stable and highly efficient ammonia synthesis. Nitrogen vacancies are generated on LaN with low formation energy, and efficiently bind and activate N2. Credit: Tokyo Tech Ammonia (NH3) is one of the most commonly produced chemicals worldwide, because…
“#Higher-order topology found in 2-D crystal” WTe2 Josephson junction: Green slabs are layers of WTe2, orange bars are niobium electrodes, and red and blue lines denote spin up and spin down electrodes traveling on two hinges of the samples. Credit: Gil-Ho Lee (POSTECH) Over the last decade, the field of condensed matter physics has experienced…
