A highly efficient, direct C(sp3)–H cyanation was developed under mild photocatalytic conditions. The method enabled the of various substrates with excellent functional group tolerance. Notably, complex natural products and bioactive compounds were efficiently cyanated.
Ice accumulation is a persistent problem in high-altitude or low-temperature environments, resulting the abnormal operation of equipment and even fatal accidents. As such, various strategies for removing (de-icing) preventing (anti-icing) ice from outdoor have been proposed. In this study, simple photothermal superhydrophobic coating system was developed by combining hydrophilic/hydrophobic silica agglomerates, polydimethylsiloxane matrix, organic dyes (diaminonaphthyl fluorine, DANF) to...
Liquefied natural gas (LNG) gasification coupled with adsorbed (ANG) charging (LNG-ANG coupling) is an emerging strategy for efficient delivery of gas. However, the potential LNG-ANG to attain advanced research projects agency-energy (ARPA-E) target onboard methane storage has not been fully investigated.

We report high experimental p-xylene (pX) selectivity in a pillar-layered metal-organic framework, DUT-8(Cu). Vapor- and liquid-phase adsorption experiments were carried out to confirm pX large uptakes Grand canonical Monte Carlo simulation results show that the presence of DABCO ligands allows for packing molecules is responsible selective nature material. The also suggests isooctane solvents plays an essential role by lowering other xylene isomers, leads increased as compared vapor phase....
Climate change is increasing the uncertainty of global hydrological cycles, leading to an increase in extreme weather events such as heatwaves, droughts, and floods. While continental-scale analyses based on CMIP6 (Coupled Model Intercomparison Project Phase 6) climate scenarios have been actively conducted, detailed for specific regions are still lacking. Furthermore, comparing model predictions with observation data initial 10-year period (2015-2024) models important validating short-term...
Thermosetting polymers have been widely used in a variety of industrial applications due to their improved mechanical robustness, chemical inertness, and thermal stability. However, thermosetting waste, which is generally unrecyclable, has become major cause environmental pollution. Recently, research into dynamic bonding chemistries like transesterification carbamate exchange emerged, indicating covalent adaptable networks (CANs) as promising contenders for the recycling cross-linked...

Our studies revealed that the steric electronic effects of play key, yet distinct roles in these polymerization reactions. The thermal properties polyketones engineered by varying styrene content terpolymers derived from ethylene, styrene, CO sources, increased ratios yielding reduced polyketone crystallinity.
Driving a vehicle requires performing combination of cognitive, visual, and manual tasks, which depend on the sensory cognitive resources allocated to task. Physiological measures, such as heart rate can be used objectively detect when driving task demands approach exceed driver’s available resources, at point there are also performance effects. As humans gain experience automatize aspects it, fewer demanded, is reflected in physiological measures. However, response changes with age. This...
Globally important hydroclimatic variations take place over monsoon Asia. However, sound understanding of hydrological processes is still challenging due to the unevenly distributed observation stations.

Even though precipitation is main driver shallow landslides and debris flows, use only rainfall-based parameters has shown some limitations. Soil moisture been used widely to improve threshold detection capabilities. Since soil directly reflects wetness status ground, it can be identify pore pressure fluctuations more effectively. This study rainfall simultaneously...
