Article Abstract
Visible light is a more accessible and less phototoxic excitation light source in practical applications than ultraviolet light. However, it's still a challenge to prepare visible-light-excited carbon-dot long-afterglow photochromic materials. In this study, a carbon dots/boronic acid composite (CDs/BA) based on boron-carbon bond (BC) was synthesized. The CDs/BA under visible light excitation had a long-afterglow emission spectrum mixed of thermal activation delayed fluorescence (TADF) and room temperature phosphorescence (RTP), with an absolute photoluminescence quantum yield (PLQY) up to 30.35 %. After removed the visible light excitation source, the long afterglow lasted for more than 30 s. Moreover, the long afterglow emission of CDs/BA is excitation-dependent and time-dependent. On this basis, the anti-counterfeiting technology with more convenience (a mobile phone or flashlight can be used as a light source) and higher security was achieved.

Ice gliding diatoms establish record-low temperature limits for motility in a eukaryotic cell.

Despite periods of permanent darkness and extensive ice coverage in polar environments, photosynthetic ice diatoms display a remarkable capability of living inside the ice matrix. How these organisms navigate such hostile conditions with limited light and extreme cold remains unknown. Using a custom subzero temperature microscope during an Arctic expedition, we present the finding of motility at record-low temperatures in a Eukaryotic cell.

Behaviorally informed "nudges" are widely used in government outreach but are often seen as too modest to address poverty at scale. In four field experiments over 2 y ( = 542,804 low-income households), we test whether more proactive communication, varying message framing, and more precise targeting can boost take-up of tax-based benefits in California above and beyond traditional light-touch approaches. Our interventions focused on extremely vulnerable households, most with no prior-year earnings, who were at risk of missing out on two crucial benefits: the 2021 expanded Child Tax Credit and pandemic-relief Economic Impact Payments.

ConspectusMolecular photochemistry, by harnessing the excited states of organic molecules, provides a platform fundamentally distinct from thermochemistry for generating reactive open-shell or spin-active species under mild conditions. Among its diverse applications, the resurgence of the Minisci-type reaction, a transformation historically reliant on thermally initiated radical conditions, has been fueled by modern photochemical strategies with improved efficiency and selectivity. Consequently, the photochemical Minisci-type reaction ranks among the most enabling methods for C()-H functionalizations of heteroarenes, which are of particular significance in medicinal chemistry for the rapid diversification of bioactive scaffolds.

The challenge of photocatalytic hydrogen production has motivated a targeted search for MXenes as a promising class of materials for this transformation because of their high mobility and high light absorption. High-throughput screening has been widely used to discover new materials, but the relatively high cost limits the chemical space for searching MXenes. We developed a deep-learning-enabled high-throughput screening approach that identified 14 stable candidates with suitable band alignment for water splitting from 23 857 MXenes.

Neuropeptide Y (NPY) and the voltage-gated potassium channel Kv1.3 are closely associated with breast cancer progression and apoptosis regulation, respectively. NPY receptors (NPYRs), which are overexpressed in breast tumors, contribute to tumor growth, migration, and angiogenesis.
