Ethanol steam reforming (ESR) reaction is an environmentally benign and sustainable route for H₂ production. Herein, the authors demonstrate a conceptional strategy for rational design and preparation of highly-efficient catalyst toward ESR via an RhNi-TiO₂ strong bimetal-support interaction.

Heterogeneous catalysts for olefin hydroformylation are highly desired but suffer from poor activity. Herein, the authors report that rhodium nanoparticles supported on siliceous MFI zeolite with abundant silanol nests are very active for hydroformylation, affording a turnover frequency that outperforms the classical Wilkinson’s catalyst.

Crystalline porous materials are commonly based around negatively charged frameworks, so ion-exchange is limited to cations. Here, the authors report a series of positive metal-organic frameworks, capable of ion exchange of large organic anions, with potential in separation and purification applications.

There is interest in the study of two-dimensional materials for catalysis. Here, the authors report the fabrication of two-dimensional gold nanostructures, using a layered double hydroxide as a stabilizing template, and evaluate the catalytic performance of the composite for solvent free selective oxidation.

Carbon dioxide reforming can be used to valorize hydrocarbon-containing CO₂ streams without the use of external reductants, but existing methods remain inefficient. Here, an HZSM-5-encapsulated nickel catalyst is introduced that features a remarkable methane dry reforming activity combined with high methane utilization.

The collective-flow-assisted nuclear shape-imaging method images the nuclear global shape by colliding them at ultrarelativistic speeds and analysing the collective response of outgoing debris.

The tumor microenvironment (TME) has an important role in Head and Neck Squamous Cell Carcinoma (HNSCC) progression. Here, using single-cell RNA sequencing and multiplexed imaging, the authors report the cellular complexity of the TME in patients with HNSCC, exploring inflammatory status, stromal heterogeneity and immune checkpoint receptor-ligand interactions.

Tuning the environment of catalytic active sites may improve the selectivity of heterogeneous catalysts. Here, the authors modify the outer-sphere environment of active sites in hydroformylation catalysts by encapsulating the active sites in nanovessels formed by ion pair-directed supramolecular assembly.

Solvents play important roles in chemical transformations, but isolating products from solvents is cumbersome and energy-consuming. Here, the authors develop promising alternatives by anchoring the solvent moieties onto porous materials for creating solvation environments in heterogeneous catalysts for efficient biomass conversion.

The hydrogenation of CO₂ into valuable chemicals is greatly demanded, but suffers from complex product distribution. Here, the authors reported that, as a support and ligand, silica boosts cobalt catalysts to selectively hydrogenate CO₂ into the desired methanol product.

Mechanisms of sleep remain elusive. Here, authors developed mouse sleep fMRI based on simultaneous electrophysiology and mapped global and sequential state transition patterns, together with global patterns triggered by SWRs in NREM and awake states.

An understanding of the domestication of the yeast Saccharomyces cerevisiae has important implications for studying its evolution and diversity. Here, the authors show that Far East Asia is likely the center of origin of the domesticated populations of the yeast based on genomic and phenotypic characterization of a large collection of isolates.

Supported metal nanoparticles are indispensable catalysts in industry, yet they are often subjected to severe sintering. Now, a general method based on metal immobilization within zeolite is reported for the preparation of highly sinter-resistant catalysts for a broad range of industrially relevant processes.

Fusarium graminearum is a fungal pathogen of wheat and other cereals. Here the authors identify a gene cluster in F. graminearum encoding the production of a non-ribosomal peptide that is required for infection of wheat through cell-to-cell penetration.

Understanding of the structures and roles of catalyst promoters markedly lags behind the understanding of the structures and roles of catalytic sites. Here, the authors address this challenge by incorporating a single-site promoter—tin—on a TiO₂ surface to enhance the catalytic activity of various metals on the TiO₂ in selective hydrogenation of nitroarenes.

SETDB1 is a histone methyltransferase and a role for the protein has been proposed in cancer. Here, the authors show that SETDB1 contributes to hepatocellular cancer by preferably forming a complex with mutant p53, resulting in di-methylation of a critical lysine residue and stabilization of the protein.

The evolution and phylogenetic placement of gnetophytes have remained elusive. The draft genome for a gnetophyte, Gnetum montanum, is now reported. Comparative analyses identify genomic features distinguishing gnetophytes from other gymnosperms.

The selective oxidation of methane to methanol using O₂ under mild conditions has been a challenge for decades. Now, this transformation is selectively achieved at ambient temperature with productivity as high as 67.4 μmol g_cat⁻¹ h⁻¹ on a reduced phosphomolybdate catalyst, where H₂ is required to keep the catalyst surface in a reduced state.

The only known animal polyketide-nonribosomal peptides, the nemamides, are biosynthesized by two megasynthetases in the canal-associated neurons (CANs) of C. elegans. Here, the authors map the biosynthetic roles of individual megasynthetase domains and identify additional enzymes in the CANs required for nemamide biosynthesis.
