Chemical looping processes can be mediated by redox-active metal oxides. This cover image depicts a doped metal oxide surface at which conversions of substrates such as methane, water, carbon dioxide and carbon monoxide can occur. See Gong et al
Pristine molybdenum disulfide undergoes oxidation at its basal plane, such that some S atoms are replaced with O atoms. This new doped monolayer exhibits improved activity for electrocatalytic hydrogen evolution.
Chiroptical molecular switches change chirality in response to light. Christian Petermayer and Henry Dube report a new type of hemiindigo photoswitches that feature axial chiral substituents and are characterized by an unusual decoupling of the absorption and the circular dichroism (CD) spectra.
The modification of DNA at cytosine and thymine, such as methylation, hydroxylation and formylation, might have epigenetic roles. In this Review, the authors discuss established and newer methods for the detection of these modifications in genomic DNA.
One promising technology for modern energy and chemical conversions is chemical looping, central to which are redox cycles of metal oxides. This Review describes chemical looping schemes and the mechanisms by which metal oxide particles enable these technologies.
Large increases in the amount of information produced year on year motivate the development of new storage media. This Review addresses the current status of data storage at the level of single polymer chains: in DNA, proteins and synthetic polymers.
This Perspective describes the physical molecular driving forces that stabilize native lignocellulosic plant biomass structures and govern thermochemical biomass pretreatments. Understanding these driving forces can help us to design efficient methods for deconstructing biomass into biofuels and other bioproducts.
