Dissociation

In chemistry, the classification of substances into acids and bases is fundamental.

A novel method that employs palladium to inject hydrogen into the deeply buried oxide-metal electrode contacts of amorphous oxide semiconductors (AOSs) storage devices, which reduces contact resistance, has been developed by scientists at Tokyo Tech. This innovative method presents a valuable solution for addressing the contact issues of AOSs, paving the way for their application in next-generation storage devices…

Pt-based catalysts have been extensively employed in catalytic propane dehydrogenation (PDH) processes, playing a crucial role in propylene production. However, monometallic Pt catalysts often exhibit inferior propylene selectivity due to the hydrogenolysis, rapid deactivation from coke deposits, and nanoparticle sintering. To address these challenges, various metals (Sn, Zn, Ga, Co, etc.) have been introduced to…

When it comes to our world, our Solar System, and all the planets, stars, and galaxies we can detect within our Universe, we find that they're all made up of the same ingredients: atoms. And from the…

Hollow-structured supported metal catalysts (i.e. nanoreactor catalysts) with encapsulated active sites and well-defined shells provide an ideal place for multicomponents to react or transform cooperatively in an orderly manner, and efficiently have been recognized as one of the most popular catalyst candidates.

New Stanford University research has revealed that the mineral silica, a common food additive and popular cosmetics ingredient, is not a chemically inert substance, as has long been supposed.

NASA's new space telescope uses its high-resolution spectrometer to find hydrogen peroxide around Ganymede's poles and sulfur monoxide emerging from Io's volcanos

A team of researchers has developed a highly efficient and stable copper-based catalyst (DFNS/TiO2-Cu) for converting CO2 to CO, with a CO productivity of 5350 mmol g−1 h−1 and 99.8% selectivity. The catalyst remained stable for over 200 hours and in-situ studies highlighted the importance of defect

Chemical engineers from the University of Wisconsin-Madison have created a model of catalytic reactions at the atomic scale using simulation techniques.

A research group led by Prof. Wu Kaifeng from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), in collaboration with Dr. Peter C. Sercel from the Center for Hybrid Organic Inorganic Semiconductors for Energy, recently reported the utilization of lattice distortion in lead halide perovskite quantum dots (QDs) to control their exciton fine structure.

Roughly 70% of neon produced in the world is used in semiconductor chip manufacturing, and a shortage might cause big disruptions.

Hydrogen production using sunlight energy (solar-water splitting) has gained much attention in the quest to move towards carbon-neutral technologies. If chemical products with applications in the health and food industries could be produced at the same time as hydrogen, this would help reduce the cost of solar-water splitting, as well as increasing the technology's range of applications.

In a recent study, scientists provide evidence of the effects of photodissociation on the quantum level for an atmospheric pollutant, formaldehyde, thereby showing photodissociation reactions can't be treated classically, like 'billiard-balls' coming together, colliding and reconnecting, said an author of a new study.

Surging solar activity means enormous sunspots are in the space-weather forecast. Here's how to view them safely

Although their primary purpose is to look for exoplanets, observatories like the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) have supplied a vast amount of data on stellar flares, detected with high-precision photometry by broadband filters in the visible light spectrum.

NASA's Juno spacecraft helped scientists make the first direct measurement of molecular oxygen around Jupiter's moon Europa. The result is lower than some...

The Wnt signaling pathway, a system present in living organisms, plays a pivotal role in cell growth, differentiation, and migration. It has a long history dating back to 1982, when the first Wnt gene, essential for cellular growth, was discovered. The pathway is initiated by Wnt ligands, a set of 19 glycoproteins that transmit signals through specific receptors and proteins, leading to modifications in gene…

Humans may never be able to tame the sun, but hydrogen plasma—making up most of the sun's interior—can be confined in a magnetic field as part of fusion power generation: with a caveat.
