Alpha radiation combines high linear energy transfer with minimal tissue penetration, damaging cancer cells let
A polarization-driven guide to making high-performance, versatile solar cells
3dWhen solar cells are exposed to sunlight, certain bound "charge pairs" are generated in its components, which need to be separated for photocurrent generation. Ferroelectric materials, due to their spontaneous electric polarization, are highly efficient at charge separation but do poorly in light-to-electricity conversion. Now, scientists from Korea have demonstrated using theoretical calculations

Cultivation of elusive microbes unearthed exciting biology
4dNature Communications, Published online: 04 January 2021; doi:10.1038/s41467-020-20393-9 Many newly-discovered microbial phyla have been studied solely by cultivation-independent techniques such as metagenomics. Much of their biology thus remains elusive, because the organisms have not yet been isolated and grown in the lab. Katayama et al. lift the curtain on some intriguing biology by cultivati
Neutralizing antibody titres in SARS-CoV-2 infections
4dNature Communications, Published online: 04 January 2021; doi:10.1038/s41467-020-20247-4 Here, the authors perform plaque reduction neutralization (PRNT) assays quantitating SARS-CoV-2 specific neutralizing antibodies from 195 patients in different disease states and find that patients with severe disease exhibit higher peaks of neutralizing antibody titres than patients with mild or asymptomatic
The origin of the Moon's Earth-like tungsten isotopic composition from dynamical and geochemical modeling
4dNature Communications, Published online: 04 January 2021; doi:10.1038/s41467-020-20266-1 Tungsten isotopes between the Earth and Moon are compared in this new study. The authors find that traditional models of Moon formation are very unlikely to reproduce the Moon's Earth-like isotopic composition.
Nanoscale decoupling of electronic nematicity and structural anisotropy in FeSe thin films
4dNature Communications, Published online: 04 January 2021; doi:10.1038/s41467-020-20150-y Here, in contrast to previous observations in Fe-based superconductors, scanning tunnelling microscopy of strain-patterned FeSe thin films reveals a local decoupling of electron nematicity and structural anisotropy, pointing towards a stiffness of the nematic order parameter at the nanoscale.
Atomically thin photoanode of InSe/graphene heterostructure

Synthesis of bio-based methylcyclopentadiene via direct hydrodeoxygenation of 3-methylcyclopent-2-enone derived from cellulose
4dNature Communications, Published online: 04 January 2021; doi:10.1038/s41467-020-20264-3 Synthesis of methylcyclopentadiene (MCPD) with abundant biomass is appealing. Here the authors show that cellulose-derived 3-methylcyclopent-2-enone can be directly hydrodeoxygenated to MCPD over a partially reduced Zn-Mo oxide catalyst.
Robust and efficient hydrogenation of carbonyl compounds catalysed by mixed donor Mn(I) pincer complexes
4dNature Communications, Published online: 04 January 2021; doi:10.1038/s41467-020-20168-2 Manganese-based hydrogenation catalysts are sensitive to high temperatures and may degrade under industrially relevant conditions. Here, the authors report a highly efficient manganese pincer pre-catalyst displaying high TOF values (up to 41 000 h−1) and stability (TON up to 200 000) at loadings as low as 5-2
Unified divergent strategy towards the total synthesis of the three sub-classes of hasubanan alkaloids
