This study introduces two new measures of brain function at the gray–white matter boundary, revealing distinct patterns of signal transmission and metabolic activity that deepen our understanding of brain organization and development.

Commercial solutions to assess air quality and safety in underground mines often suffer from low accuracy, high installation and maintenance costs, without providing data on noxious gases. Here, the authors present a wireless, battery-free sensing platform for environmental monitoring of underground mines.

The sustainable fabrication of perovskite solar cells is critical. Duan et al. present a more environmentally friendly solvent system to process wide-bandgap perovskite films that can also be used for industrial-scale manufacturing in ambient air.

Using a mixture of 4-fluorophenethylamine and 4-trifluoromethyl-phenylammonium to create a tailored 2D perovskite layer reduces the inhomogeneity at the top interface of all-perovskite tandem cells and results in the highest efficiency reported so far.

Substantial open-circuit voltage loss and inherent non-radiative recombination hinder efficiency improvements in wide-bandgap perovskite solar cells. Here the authors augment two-dimensional perovskite phases on the surface to promote (100) facet growth on three-dimensional perovskite facets, improving the open-circuit voltage and efficiency of the resulting wide-bandgap perovskite solar cells.

All-perovskite tandem solar cells with an immiscible 3D/3D bilayer heterojunction demonstrate a record-high PCE of 28%, as well as the ability to retain more than 90% of their initial performance after 600 h of continuous operation.

The efficiency of flexible perovskite solar cells lags behind their rigid counterparts. Now, Li et al. devise a self-assembled monolayer bridged hole-selective contact with reduced defects and improved bending durability, achieving a 24.4% certified efficiency.

The superstate configuration in all-perovskite tandem solar cells is disadvantageous for long-term stability. Here, the authors reverse the processing order and demonstrate substrate configuration to bury oxidizable narrow-bandgap perovskites, and achieve efficiency of 25.3% with long stability.

The scalable fabrication of wide-bandgap perovskites in air remains challenging due to moisture-induced degradation of perovskites. Here, authors utilize low polarity and moderately volatile n-butanol to enhance film uniformity, achieving efficiency of 29.4% for double-sided textured tandem cells.

In this study, the authors report the development of an inhalable IgM-like ACE2 and show that it broadly neutralizes SARS-CoV-2 variants, lowers viral loads and lung pathology in hamsters when administered early, and has good safety profiles in rats and monkeys.

A certified efficiency of 26.4% in all-perovskite tandem solar cells, exceeding that of the best-performing single-junction perovskite solar cells, is achieved by control over surface defects in the Pb–Sn subcell.

This work reports a facile method for growing highly ordered Pt and Mn bimetallic single atomic layers on graphdiyne. This fully activates loaded metal atoms and results in in high activity and selectivity for electrocatalytic alkene-to-diol conversion

The phase diagram of confined ice is different from that of bulk ice. Simulations now reveal several 2D ice phases and show how strong nuclear quantum effects result in rich proton dynamics in 2D confined ices.

Silicon-integrated graphene photodetectors exhibit promising bandwidths at telecom wavelengths, but their responsivity is usually limited. Here, the authors report the wafer-scale fabrication of waveguide-integrated detectors based on twisted bilayer graphene, showing responsivities up to 0.65 A/W and 3-dB bandwidths >65 GHz.

The thiol–gold interaction is a fundamental one for the functionalization of nanoparticles and surfaces. Here, the authors use AFM to study individual thiol–gold contacts, showing that oxidized gold surfaces enhance the stability, in addition to monitoring shifts from coordinated to covalent bonding.

The need for cheap water-splitting materials in order to scale-up and commercialize solar-to-fuel technologies is urgent, but there are still few candidate materials. Here, authors integrate layered double hydroxides with graphdiyne as high-performance overall water-splitting electrocatalysts.

While hydrogen as a renewable fuel can be produced from water, there is a scarcity of metal-free materials that serve as effective electrocatalysts. Here, authors functionalize carbon fiber cloth with amides to improve hydrogen evolution activities in both acid and alkaline water.

While water electrolysis represents a promising means for renewable hydrogen production, the catalysts needed must be efficient at high current densities. Here, authors show rhodium nanocrystals on graphdiyne to efficiently evolve hydrogen from saline water.

A freestanding three-dimensional graphdiyne-hollowed FeCoNi Prussian blue analog electrode (h-FeCoNi PBA@GDY) with highly selective and active interfaces was synthesized by in situ growth of GDY layer on the surface of h-FeCoNi PBA for electrocatalytic nitrate reduction reaction (ECNtRR) at ambient temperatures and pressures. Experimental results demonstrate the presence of the unique incomplete charge transfer between metal atoms and GDY can effectively enhance the intrinsic activity and the ability to increase the active sites of the electrocatalyst, promote fast redox switching, and high-density charge transport at the interface resulting in high reaction selectivity, activity and stability for ammonia production.

Single atom catalysts provide the most efficient metal atoms usage and afford active site homogeneity, but surface attachment has proven challenging. Here, the authors use triple-bond-rich graphdiyne to anchor nickel/iron atoms and show high hydrogen evolution electrocatalysis activities.

Non-Hermitian physics, an active topic in photonics, is also being increasingly extended to investigate the band topologies of condensed-matter systems. Here, the authors report a 2D non-Hermitian model exhibiting exceptional rings and topological boundary modes in the spectral degeneracy, they propose how to realise these features using topolectrical circuits.
