'Electronic nose' determines food freshness
A new device analyzes gas mixtures using semiconductor sensors. Odor is determined by a combination of existing gases in the atmosphere. Researchers have found that the conductivity of a semiconductor probe changes during sedimentation of the gas molecules from the atmosphere, which indicates their presence, says Timur Muksunov. During manufacture, the sensor can be customized to react differently to various atmospheric gases.

Catalyst produces hydrogen through steam reforming of biomass-derived ethylene glycol
Hydrogen production through steam reforming biomass-derived compounds is an economically feasible and environmentally benign way to efficiently use renewable energy resources. A study by scientists at Pacific Northwest National Laboratory compared the hydrogen yield achieved by several different metal catalysts used for steam reforming ethylene glycol. The findings show a cobalt catalyst had a much higher hydrogen yield than rhodium or nickel catalysts, making it a promising catalyst for steam reforming ethylene glycol for hydrogen production.

Towards eco-friendly industrial-scale hydrogen production
What if industrial waste water could become fuel? With affordable, long-lasting catalysts, water could be split to produce hydrogen that could be used to power fuel cells or combustion engines. By conducting complex simulations, scientists showed that adding lithium to aluminum nanoparticles results in orders-of-magnitude faster water-splitting reactions and higher hydrogen production rates compared to pure aluminum nanoparticles. The lithium allowed all the aluminum atoms to react, which increased yields.

Safe and inexpensive hydrogen production as a future energy source
Hydrogen gas is a promising alternative energy source to overcome our reliance on carbon-based fuels, and has the benefit of producing only water when it is reacted with oxygen. However, hydrogen is highly reactive and flammable, so it requires careful handling and storage. Typical hydrogen storage materials are limited by factors like water sensitivity, risk of explosion, difficulty of control of hydrogen-generation. Hydrogen gas can be produced efficiently from organosilanes, some of which are suitably air-stable, non-toxic, and cheap. Catalysts that can efficiently produce hydrogen from organosilanes are therefore desired with the ultimate goal of realizing safe, inexpensive hydrogen production in high yield. Ideally, the catalyst should also operate at room temperature under aerobic conditions without the need for additional energy input.

Controlling electron spin makes water splitting more efficient
One of the main obstacles in the production of hydrogen through water splitting is that hydrogen peroxide is also formed, which affects the efficiency stability of the reaction and the stability of the production. Dutch and Israeli researchers from Eindhoven University of Technology and the Weizmann Institute have succeeded in controlling the spin of electrons in the reaction and thereby almost fully suppress the production of hydrogen peroxide. They published these findings this week in the Journal of the American Chemical Society. The efficient production of hydrogen paves the way towards water splitting by solar energy.

Ultrathin black phosphorus for solar-driven hydrogen economy
Hydrogen as a fuel source, rather than hydrocarbons like oil and coal, offers many benefits. Burning hydrogen produces harmless water with the potential to eliminate carbon dioxide emissions and their environmental burden. In pursuit of technologies that could lead to a breakthrough in achieving a hydrogen economy, a key issue is making hydrogen cheaply. Using catalysts to split water is the ideal way to generate hydrogen, but doing so usually requires an energy input from other chemicals, electricity, or a portion of sunlight which has high enough energy.
