Wireless magnetic control of gene expression in mammalian cells has been developed based on intracellular nanointerface and ROS-mediated signalling. The approach allows remotely tunable insulin release and regulates blood glucose in diabetic mice.
The authors present a customized operando synchrotron X-ray platform to track simultaneously ion, water and catalyst evolution in CO2 electrolysis based on membrane-electrode assembly. Enhanced Au durability is caused by a robust crystal structure and strong adhesion to substrate.
An achromatic metagrating waveguide with a tailored periodic structure designed using a stochastic topology optimization algorithm efficiently guides red, green and blue light at the same angle. This structure provides a compact, lightweight architecture for waveguide-based full-colour augmented reality displays.
A 500-μm-thick design simplifies fabrication and reduces weight while offering good brightness and colour uniformity for augmented reality near-eye optical design.
Nanoscale, covalently bonded GeSe crystals can withstand up to 12.8% recoverable tensile strain through an atomic mechanism called reversible shuffle twinning, giving rise to anisotropic superelasticity.
Porous and hollow silk fibroin microneedles nanofabricated with phase front assembly allow the authors to establish a prolonged interface with plants for delivery of micronutrients, crop fortification and continuous plant health monitoring.
This study presents an oral CRISPR–Cas9 delivery system that precisely disrupts the TRAP1 gene in colorectal cancer, enhancing chemo-immunotherapy with robust antitumour effects.
Piracetam improves wide-bandgap perovskite crystallinity and uniformity, enabling monolithic all-perovskite tandem solar cells with efficiencies of 28.71% (0.07 cm2) and 28.20% (1.02 cm2), ensuring minimal efficiency loss during scale-up.
This study reveals that the synergistic effect of proton-limited environments and multi-site cooperative activation coupling substantially improves the electrocatalytic co-reduction of CO2 and N2 towards urea production, enabling gram-scale synthesis.
Lewis acid additive semicarbazide hydrochloride improves the formation of α-phase FAPbI3-based films and promotes a homogeneous vertical distribution of A-site cations through a deprotonation–reprotonation process. The upgraded device performance reaches up to 26.12% with high stability, and mini-module perovskite solar cells achieving 21.47% (area, 11.52 cm2) demonstrate great scalability.
Caesium cations promote the coagulation of 2D and 3D perovskite colloids, synchronizing their nucleation kinetics and enabling the formation of homogeneous 2D/3D heterostructured lead-free photovoltaics with a certified power conversion efficiency of 16.65%.
A nanoporous photocatalyst producing low levels of hydrogen peroxide is shown to modulate intracellular stress granules, enhancing resilience against oxidative stress and providing cardioprotection in an ex vivo rodent model of myocardial ischaemia–reperfusion injury.
By controlling the contribution of secondary nucleation in the self-assembly of chiral photoswitch molecules using light, it is possible to preferentially generate metastable aggregates, thereby reversing the supramolecular chirality.
In battery research, the areas of the electrodes and cell dimensions affect the energy storage performance. Here the authors discuss the factors that influence the reliability of electrochemical measurements and battery performance in lithium-ion cells with different electrode areas.
