I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Reducing nitrogen with boron and beer” Boron can be used to convert nitrogen to ammonium. Credit: Team Braunschweig Humankind is reliant on the ammonium in synthetic fertilizer for food. However, producing ammonia from nitrogen is extremely energy-intensive and requires the use of transition metals. Researchers from Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, have now achieved…
“#Researchers create morphing crystals powered by water evaporation” Researchers have developed tripeptide crystals (illustrated above), which feature aqueous pores that expand and contract in response to humidity changes and use evaporation to create an effective mechanical actuator. Credit: Tony Wang Water evaporation, as observed when a puddle of water disappears on a summer day, is…
“#Bimetallic catalyst helps to synthesize tunable imines and secondary amines” Figure 1. Characterization of bi-metallic NiCo5 catalyst. Credit: CHEN Chun In a recent study, scientists from the Institute of Solid State Physics, Hefei Institutes of Physical Science prepared NiCo5 bi-metallic catalyst to activate carbon-nitrogen bond under mild reaction conditions. Imines, amines and their derivatives have…
“#Researchers find cuttlebone’s microstructure sits at a ‘sweet spot’” Postdoctoral researcher Zian Jia examines a 3D-printed model of cuttlebone’s microstructure. Credit: Peter Means for Virginia Tech. Ling Li has a lesson in one of his mechanical engineering courses on how brittle materials like calcium carbonate behave under stress. In it, he takes a piece of…
“#Atomic-level insights help to reduce degradation in fuel cells and extend their lifetime” Atomic force microscopy images showing varied coverage of a gold layer (the lighter shade) over the edges of a platinum surface. The gold layer mitigates platinum dissolution during fuel cell operations. Credit: Argonne National Laboratory Vehicles powered by polymer electrolyte membrane fuel…
“#Inexpensive, non-toxic nanofluid could be a game-changer for oil recovery” Credit: Unsplash/CC0 Public Domain Researchers from the University of Houston have demonstrated that an inexpensive and non-toxic nanofluid can be used to efficiently recover even heavy oil with high viscosity from reservoirs. The nanofluid, made in a common household blender using commercially available sodium, allowed…
“#Solvation rearrangement brings stable zinc/graphite batteries closer to commercial grid storage” Tuning the anion solvation network of carbonate-based electrolyte for high-voltage Zn/graphite batteries. Credit: Zhao Jingwen With grid-scale renewable energy on the rise, many scholars have shifted their attention from energy generation to energy storage. Whether it is solar cells converting sunlight into power, or…
“#Rationally designing hierarchical zeolites for better diffusion and catalyst efficiency” Hierarchical structures at both zeolitic component and industrial catalyst levels Credit: Science China Press Thanks to various crystalline topologies, tunable chemical composition, high (hydro)thermal stability, and controllable surface acidity/basicity, zeolites are widely used in petroleum refining, petrochemical manufacture, fine chemical synthesis, biomedicine, environmental chemistry, etc….
“#Scientists predict new superhard materials” Credit: Pixabay/CC0 Public Domain A group of Skoltech scientists used machine learning (ML) methods to predict superhard materials based on their crystal structure. The research was published in the Journal of Applied Physics. Superhard materials have recently attracted increasing research interest due to their potential implications for industries broadly ranging…
“#Establishment of a rapid synthesis method for useful organic fluorine compounds” The reaction of triflones with the organic magnesium Grignard reagent allows for the synthesis of gem-difluoroalkenes Credit: Issey Takahashi The Nagoya University Institute of Transformative Bio-Molecules (WPI-ITbM) research team of Professor Cathleen Crudden, Designated Lecturer Masakazu Nambo, JSPS Postdoctoral Fellow Yuki Maekawa and Associate…
