Life requires chemical chiral specificity. The emergence of enantioselectivity is unknown but has been linked to diverse scenarios for the origin of life, ranging from an extraterrestrial origin to polarization-induced effects, and magnetic field-induced mineral templating. These scenarios require an originating mechanism and a subsequent enhancement step, leading to widespread chiral specificity.

The human visual system's real-time focus-tunable imaging capability has inspired curved imaging system development. However, curved image sensors mimicking the human retina typically lack tunable curvature to match the curved Petzval surface throughout the focus-tunable range. Here, we propose a focus-tunable real-time curved imaging system based on a tunable-curvature perovskite curved image sensor.

Accurate strain monitoring in environments with coexisting mechanical deformation and temperature fluctuations─such as solid rocket propellants, battery enclosures, and human ligaments─remains a longstanding challenge for flexible electronics. Conventional strain sensors suffer from significant thermal drift due to the intrinsic temperature dependence of their sensing materials, limiting their reliability in wireless and implantable applications. Here, we report an intrinsically temperature-insensitive, highly sensitive, wireless flexible strain sensor based on near-field communication technology.

A method was developed to sample molten salts by sparging to generate and transport aerosols to an isolated instrument for compositional analysis by laser-induced breakdown spectroscopy (LIBS). Real-time monitoring of molten salt composition is critical to developing molten salt nuclear reactors, which offer enhanced safety and efficiency. In this article, the sparge sampling method is described and compared with sampling using a Collison nebulizer.

The efficiency of most electronic devices is limited by scattering and capacitive losses among purely electronic processes. Charge-neutral excitons could reduce both losses and, thus, offer more efficient switching pathways. However, it remains challenging to achieve exciton transport that is fast, guided, and unidirectional enough for gating processes.
