Short hydrogen bonds in proteins and their quantum mechanical nature
The assembly of linear polypeptide chains into functional three-dimensional protein architectures involves a unique force called hydrogen bonding. A typical hydrogen bond forms when the donor and acceptor groups approach each other with a nearly linear geometry
Capturing hydrogen transfer from modeling: a small step towards simulating chemical reactions by computers
All the matter of the world around us are made of atoms that are joined to form molecules. Chemists can create new molecules by changing connectivity of atoms in molecules through chemical reactions. Researchers can control reaction
Hydrogen storage in lithium-terminated boron chains
Hydrogen can be used as alternative energy source because of many advantages. Despite the high energy content by mass, hydrogen has low density, and it is necessary to develop an efficient storage medium to use this technology
A stirring-free photoelectrochemical cell for solar hydrogen production
Direct conversion of solar energy to hydrogen via photoelectrochemical (PEC) water splitting is a promising approach to a sustainable-energy society, because hydrogen is storable, transportable, and can be converted to electricity without producing carbon dioxide. PEC cells
Hydrogen bonded Frameworks for CO2 capture and more
Hydrogen bonded frameworks (HOFs) have been known for a long time. In recent times, there has been enormous interest in their rational design from a wide library of hydrogen bonding molecules with varying geometries. Among the porous
Lithium ion intercalation for boosting photoelectrochemical water splitting performance of TiO2 photoelectrode
Energy shortage and environmental pollution inspire the exploration of clean, renewable, and non-fossil energy carriers. Hydrogen, as “the world’s cleanest energy” because of its raw materials and products are water, and high energy content per unit mass
How hydrogen atoms bind to metal surfaces
Chemical reactions at surfaces are exceptionally complex as they require a multitude of elementary steps. The first step in every surface reaction is the adsorption of the participating atoms and molecules to the surface. Only if the
Biocatalysts for hydrogen fuel cell: Biology’s unique way to prevent breakdown by oxygen
Hydrogen could fuel the future! Together with oxygen, hydrogen can be converted to electricity with only water as an exhaust product. The conversion from hydrogen to electricity is done in fuel cells, which require a platinum catalyst.
Fuel from sunlight and the new energy economy
Hydrogen is a clean-burning fuel that is gaining increasing attention as the renewable energy economy continues to evolve. Hydrogen fuel stations appearing in California and the release of a commercial fuel-cell vehicle in mid-2015 by Toyota are
Chemically exfoliated MoS2 on TiO2 mesocrystal with efficient photocatalytic hydrogen evolution
Over the past decades, the rapid depletion of fossil fuels and serious environmental pollution were started to strongly affect the modern society. With concerning the deficiency of human energy and alleviating the environmental pollution, solar energy as
Gaining insight in biological hydrogen production by computational approaches
Hydrogen is one of the most important raw materials for the chemical industry and has an undisputed future importance as an environmentally friendly fuel. At present, 96% of the 500 billion m3 of hydrogen gas that is
Confirming Aluminum Homocatenation
The capacity of atoms to form bonds with themselves producing chain-like structures, so called atomic homocatenation, plays an important role in the life formation. Carbon is capable of forming very long chain in the CnHn+2 alkanes. Other
