Researchers at Lawrence Livermore National Laboratory (LLNL), in collaboration with the Georgia Institute of Technology, have made a significant breakthrough in understanding the impact of carbon dioxide (CO2) on the stability of amine-functionalized porous solid materials, a crucial component in direct air capture (DAC) carbon-capture technologies.

A researcher in Purdue University's College of Science is developing a patent-pending platform technology that mimics the dual-layer structure of viruses to deliver nucleic acid (NA)-based therapies to targeted cancer cells.

Scientists have determined that a rare element found in some of the oldest solids in the solar system, such as meteorites, and previously thought to have been forged in supernova explosions, actually predate such cosmic events, challenging long-held theories about its origin.

A research group led by Professor Gao Minrui from the University of Science and Technology of China (USTC) reports that nickel-tungsten (Ni-W) ratio in Ni-W alloys governs the performance of hydrogen oxidation reaction (HOR). Additionally, researchers tuned the unpaired electrons in Ni to adjust the potential of zero charge (PZC) and hydroxyl adsorption (OHad) capacity of the alloy in alkaline HODs. The results…

A new strategy was proposed in the field of aqueous zinc-ion battery to help increase the capacity of the cathodes, making them more efficient, according to a recent study published in ACS Nano.

In a Perspective, a biophysical chemist, Kenneth J. Breslauer, and his brother, a political scientist, George W. Breslauer, explore the parallelisms between the concept of stability as it is used in their respective fields. The Perspective is published in the journal PNAS Nexus.

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.

Enzyodynamic therapy (EDT) is a new type of reactive oxygen species (ROS)-related dynamic therapeutic modality, which adequately utilizes the enzyme-triggered catalytic reactions in living organisms and achieves disease treatment through controlling the generation or elimination of ROS. ROS refers to a highly active chemical substance containing oxygen free radicals in the body or natural environment. ROS at…

Hydrogen energy, as a green and environmentally friendly energy carrier, is a critical switch in energy conversion to the green economy, and the green hydrogen generation via water splitting technique from renewable energy sources is regarded as the best choice. While, the high energy input for water splitting is thermodynamically required (1.23 V), and the cell voltage can go beyond 1.8 V for the practical water…

Late last year, Caltech researchers revealed that they had developed a new fabrication technique for printing microsized metal parts containing features about as thick as three or four sheets of paper.

Scientists at the University of Sydney have, for the first time, used a quantum computer to engineer and directly observe a process critical in chemical reactions by slowing it down by a factor of 100 billion times.

Micro- and nanodisk lasers have recently emerged as promising optical sources and probes for various applications in the fields of nanophotonics and biomedicine. Their ability to achieve lasing at a deterministic wavelength and ultra-narrowband precision is critical for several applications in on-chip photonic communications, on-chip bioimaging, biochemical sensing, and quantum photonic information processing.…

The portable and electric energy storage market has long been dominated by lithium-ion batteries (LIBs) and supercapacitors, surpassing other energy storage systems in their ability to provide higher energy and power.

The agricultural industry produces a significant amount of food globally, but one third of the solid food produced each year goes to waste, resulting in negative environmental impacts and greenhouse gas emissions. To address this issue, researchers focused on converting agricultural waste, particularly pineapple peels, into a valuable carbon-negative biochar through microwave-assisted pyrolysis treatment.

The photocatalytic conversion of methane with a ubiquitous and clean oxidant of water has the potential to develop into an on-site and on-demand chemical technology for the green utilization of methane in an environmentally benign and sustainable way.
