Developing efficient anodes for H2O2 production via water oxidation remains challenging. Here, the authors report a ZnGa2O4 anode with dual active sites to improve the selectivity and to resist the decomposition of H2O2, and the peak faradaic efficiency reaches 82% at a low potential.
Controlled light transport through multimode fibres has recently emerged as uniquely atraumatic prospect to study deep brain structures. Here, authors present hair-thin endoscope providing detailed view through the whole depth of living animal brain.
Resident memory T cells at the respiratory tract may play critical roles in the response to respiratory infections including SARS-CoV-2. Here the authors characterise the lung resident T cell response generated in response to mRNA vaccination of SARS-CoV-2 Spike or in convalescent patients after natural infection. They show reduced frequency and functionality of tissue resident T cells in vaccinated versus convalescent patients which may impact disease control and vaccination strategies.
The authors describe the cocrystal structure of the highly efficient polyethylene terephthalate-degrading hydrolase PHL7 with its product terephthalic acid and elucidate the role of residues in subsites I and II for its thermal stability and of residue L210 for its high activity.
Spin-triplet exciton condensation has been predicted in perovskite cobaltites in high magnetic fields. Here, the authors report the magnetic phase diagram of LaCoO3 from magnetostriction measurements in ultrahigh magnetic fields and reveal new high-field phases with signatures of the exciton condensate.
The authors achieve ultrahigh resolution and depth volumetric imaging in complex media by recording a volumetric reflection matrix covering individual wavelengths and angles and developing reconstruction algorithms based on volumetric wave correlation.
Non-fullerene acceptors with large quadrupole moments strongly affect thin-film energetics. Here, the authors show a significant energetic shift (>200 meV) of Y6 upon changing its orientation from face-on to more edge-on using different solvents and its critical impact on organic photovoltaics.
Residual Cl ligands are found critical to the stability of amorphous TiO2 coatings by atomic layer deposition. Here, in-situ water treatment is developed to remove residual Cl, while preserve its uniform amorphous phase, which improves the lifetime of Si photoanode to 600 h for hydrogen production.
Efficient screening of protein-drug interactions (PDIs) has been impeded by the limitations of current biophysical approaches. Here, the authors present a funneled YaxAB nanopore sensor which allows label-free, single-molecule detection of proteins and PDIs.
Rational design of efficient electrocatalysts for oxygen evolution reaction is critical for water-alkali electrolysis. Here, the authors fabricate a NiMoN/NiFe layered double hydroxide and show the accelerated oxygen evolution kinetics are due to the heterointerface.
Here, the authors perform analysis of technology pathways for existing buildings using urban building energy models developed with cities, showing that shallow and deep retrofits along with onsite photovoltaic and grid decarbonization can help achieve carbon reduction targets.
Usually, increasing the temperature of a system leads to disorder but supersolids can show the opposite trend. Here, the authors discuss the observation of a supersolid phase in a dilute gas of dysprosium atoms by increasing their temperature.
Small-scale manipulation of liquids is being controlled with bulky pumps or power sources. Dradrach et al. show a light-driven pumping of micro-liter liquid using a centimeter-long liquid crystal elastomer strip.
Astrocytes act as a dynamic Cl− reservoir regulating Cl− homeostasis in the CNS. Astrocytic Cl− is high and stable during sleep, it is lower during wakefulness and fluctuates in response to sensory input and motor activity. Efflux of Cl− from astrocytes supports inhibitory transmission in the CNS.
Low rate and limited duration are major challenges in photobiological hydrogen production. Here, the authors coat algal cells with a concentrically arranged shell comprising an ultra-thin Fe(III)-doped polypyrrole inner layer and outer exoskeleton of CaCO3, and achieve sustainable H2 production for over 200 days.
In this work, authors take a multiomics and microfluidics-based approach to elucidate the mechanism of endothelial damage in critical illness associated with SARS-CoV-2.
Based on geochemical and paleontological data, this study shows that habitable open-oceans extended to mid-latitude coastal oceans during the waning stage of the Marinoan snowball Earth, offering refugia for benthic photosynthetic eukaryotes
