Canadian startup's approach could make hydrogen an everyday fuel

In the world of chemistry, understanding the difference between strong acids and weak acids is fundamental for both students and professionals alike. Strong acids are known for their ability to completely dissociate in water, making them a pivotal topic in chemical reactions and laboratory experiments.

Recently, the National Science Review published research from Prof. Jun Cheng (Xiamen University) and Dr. Jia-Bo Le (Ningbo Institute of Materials Technology and Engineering of Chinese Academy of Sciences). The research team used ab initio molecular dynamics simulation methods to study the microscopic properties of the electrochemical interface, and then applied these findings to understand the mechanism behind the…

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 underwent chemical reactions that eventually led to the origin of life.

Researchers find rust and diamonds at the Earth's core-mantle boundary. On the Earth's surface, steel rusts due to water and air. But what about deep inside the interior of the Earth? The biggest carbon storage on Earth is the Earth's core, where 90% of the carbon is buried. Scientists have show

Whether it is cars, energy or mobile phones, modern society is built on metals, and our future strongly depends on these materials, too. To store hydrogen in a safe, compact and still environmentally friendly way is still a major challenge. Metal hydrides could be an appealing solution, especially for those applications where the volume and safety of the storage system is an issue—for example, in stationary…

Researchers have developed an innovative catalyst for the synthesis of propylene, which has potential benefits for the chemical industry and carbon recycling. Their findings were reported in the journal Nature Catalysis.

Utilization of biomass as the basic feedstock for the production and chemicals and energy storage has been demonstrated to be an important alternative to achieve sustainable society, which has attracted increasing interests in both academic and industrial communities for decades.

Organic N-alkyl amines are important chemical products and intermediate with wide applications in the fields of daily chemicals, pesticides, pharmaceuticals, surfactants, and life sciences. The C–N bonds formed by alkylating reagents (halocarbons, metal halides, etc.) to produce amines usually suffer from low atomic efficiency, poor product selectivity, and chemical contaminants.

The discovery of hydrous ringwoodite inclusion in diamonds with 1.5 wt.% H2O provided an irrefutable indication that water is present in the Earth's deep mantle. Whether this water was delivered by one of the numerous subducted slabs observed by seismological studies, or whether it appeared right after the crystallization of the Earth's mantle from a magma ocean, and the total budget of water in the Earth's…

Serpentinite dehydration is essential for water recycling in subduction zones, the released fluids are considered to be a critical component in the oxidation of the sub-arc mantle. However, whether the serpentinite-derived fluids are oxidized or reduced remains hotly debated.

Glycerol, a major by-product of biomass refining accounting for approximately 10% of the yield, presents a significant challenge due to its global surplus. The presence of multiple active hydroxyl groups in glycerol unveils vast potential for the production of high-value chemicals. Formic acid (FA), a key product of glycerol conversion, is a critical organic chemical raw material with high demand in sectors such as…

Boron monoxide, a binary compound of boron and oxygen, was first reported in the 1940s.

The traditionally cumbersome yet widely-used Birch reduction can now be carried out in a mere minute in air using an optimized mechanochemical approach.

MIT chemists offer a new explanation for how collagen in dinosaur bones may have survived millions of years: An atomic-level interaction prevents its bonds from being broken down by water.

Streptomyces lunaelactis strains have been isolated from moonmilk deposits, which are calcium carbonate speleothems used for centuries in traditional medicine for their antimicrobial properties. Genome mining revealed that these strains are a remarkable example of a Streptomyces species with huge heterogeneity regarding their content in biosynthetic gene clusters (BGCs) for specialized metabolite production. BGC…

The chemical origin of life on Earth is a puzzle that scientists have been trying to piece together for decades. Many hypotheses have been proposed to explain how life came to be and what chemical and environmental factors on early Earth could have led to it. A step required in a number of these hypotheses involves the abiotic synthesis of genetic polymers—materials made up of a sequence of repeating chemical units…

A high-yield, one-pot, scalable reaction facilitates the production of biologically relevant amide compounds using less reactive nitrogen-containing heterocyclic compounds and carboxylic acid without the use of heat or special equipment.

Researchers from Carnegie Mellon University and the Chinese University of Hong Kong have developed a strategy for creating ultrahigh-resolution, complex 3D nanostructures out of various materials.
