Tungsten trioxide (WO3) is considered the most promising photocatalyst for the highly selective oxidation of methane to formaldehyde, though the origins of its catalytic activity and reaction mechanism are still debated. Here, the authors use WO3 with {001} and {110} facets as model photocatalysts, demonstrating that the photocatalytic oxidation of methane to formaldehyde in WO3 depends on the surface structure, leading to different formaldehyde selectivity.
Results show meaningful variations in electric vehicle costs and emissions benefits across the United States, differing by vehicle category and charging systems: Direct Current Fast Charging, Battery Swapping, and Dynamic Wireless Power Transfer.
Enhancing the efficiency of solar-driven water splitting is challenging but highly interesting. Here the authors report a dual spin-controlled 2D/3D perovskite photoelectrode that achieves 12.55% efficiency by utilizing the chiral-induced spin selectivity phenomenon.
Miniature passive fliers are of interest, but there are challenges in controlling their motion. Here, the authors report the use of light-responsive thin films for optical control of the gliding of passive fliers.
A variant telomerase template demonstrates that human telomeres can tolerate significant degeneracy and remain functional. Once incorporated by telomerase, variant sequences can influence telomere length dynamics.
Empirically observed regiochemistries indicate that the CF2H radical has a nucleophilic character similar to alkyl radicals, but the CF3 radical is electrophilic in reactions with heterocycles. Here, the authors report DFT calculations, reproducing experimental selectivities and leading to an explanation of this difference.
Patient-derived xenografts are important tools for cancer drug development. Here, the authors develop models from 22 non-small cell lung cancer patients. They show genomic differences between models created from different spatial regions of tumours and a bottleneck on model establishment.
Selection drives divergence between species, contributing to speciation, while simultaneously favoring extensive diversity that is maintained across populations within a species. This study demonstrates how the selection landscape is complex and multidimensional across three species of Phlox flowers.
The low photoluminescence quantum yield of near-infrared (NIR) emitters has limited their application in organic light-emitting diodes (OLEDs). Here, authors realize NIR OLEDs through interfacial energy transfer from platinum(II) complexes to a non-fullerene acceptor based on a sandwiched structure.
This study maps global tree composition in forests and assesses the impacts of historical forest cover loss and climate change. The results highlight the need for preserving the remaining large forest biomes, while regenerating degraded forests in a way that provides resilience against climate change.
Central memory CD8+ T cells (Tcm) are important for lasting anti-tumour immunity and their differentiation is determined by underpinning transcriptional and metabolic regulation. Authors here show that although microwave ablation (MWA) cancer therapy induces T cells to acquire some of the gene expression features of Tcms, but the full metabolic remodeling required for functionality is only achieved if glycolysis is inhibited simultaneously.
Topological semimetals offer the potential for new-generation spintronic devices. Here, the authors demonstrate a large out-of-plane damping-like spin–orbit torque efficiency in a heterostructure based on the Weyl semimetal TaIrTe4.
Photochromic systems with high contrast and multiple colours are useful for responsive materials, but it is challenging to achieve multiple colours with one molecule. Here, the authors report a photochromic system controlled by oxidative cleavage on light irradiation.
The severity of SARS-CoV-2 infection varied over the course of the pandemic due to factors such as changes in variant characteristics and population immunity from previous infection or vaccination. Here, the authors estimate infection hospitalisation and infection fatality rates in England over time from the start of the pandemic until March 2023.
The catalytic partial oxidation of methane (POM) is a promising technology for synthesizing syngas but suffers from severe over-oxidation on the catalyst surface. Here the authors demonstrate that regulating O* occupation in an atomically dispersed MoNi alloy can achieve high catalytic performance for POM.
Protein expression vectors in cell-free systems mainly rely on double-stranded DNA and single-stranded RNA. Here, authors use circular single-stranded DNA as a programmable vector for gene regulation in a cell-free expression system by identifying its expression pathways.
Different motor symptoms respond variably to deep brain stimulation in Parkinson’s Disease. Rajamani et al. suggest that this variability may be due to tremor, bradykinesia, rigidity, and axial symptoms being associated with a gradient of brain circuits.
Probabilistic computing demands low power and high quality random number generation. Woo et al. demonstrate the use of a spin crossover in LaCoO3 to generate random numbers that outperform software-generated random numbers in probabilistic computing.
How each mechanism of plasticity contributes to memory formation is not fully understood. Here the authors show that plasticity of intrinsic excitability exerts permissive control over the coupling of synaptic weight to neuronal output, as shown in Purkinje cells using two-photon microscopy. Non-synaptic plasticity emerges as an independent player in learning.
By introducing Ni dopants into monolayer Bi2WO6, Bi/O frustrated Lewis pairs, unsaturated W atoms, and Ni active units are formed. The authors show that these units facilitate oxygen species transfer and enhance photocatalytic toluene oxidation.
