Selective Lithium Recovery via Photothermal Evaporation and Hydration‐Controlled Adsorption

Advanced Science, EarlyView.
A bilayer Mo‐LDH@Sponge composite is developed to couple interfacial photothermal evaporation with hydration‐controlled lithium adsorption. Solar‐induced heating dynamically regulates Li+ hydration and transport, enabling selective lithium capture from saline water. This work provides mechanistic insight into photothermal–adsorption coupling for energy‐

Methylation‐Induced Permanent Charge Polarization in Covalent Organic Frameworks for Visible Light‐Driven Water Decontamination and Disinfection

Advanced Science, EarlyView.
A targeted in situ methylation strategy is developed to engineer cationic centers in a quinoline‐linked COF (NQ‐COFS1‐Me), creating a strong built‐in electric field, which effectively suppresses excitonic effects and promotes charge separation. The optimized material demonstrates powerful photocatalytic ROS generation for rapid bacterial inactivation ...

Using Personal Environmental Comfort Systems to Mitigate the Impact of Occupancy Prediction Errors on HVAC Performance

, 2018
Heating, Ventilation and Air Conditioning (HVAC) consumes a significant fraction of energy in commercial buildings. Hence, the use of optimization techniques to reduce HVAC energy consumption has been widely studied. Model predictive control (MPC) is one

EGaIn‐Activated Bioinspired Silk Micro/Nanofibril Eutectogels Breaking the Strength–Conductivity Trade‐Off for High‐Performance Wearable Bioelectronics

Advanced Science, EarlyView.
Inspired by the extracellular matrix, eutectogels are prepared by in situ deconstruction of silk fibroin into micro/nanofibrils and EGaIn‐induced polymerization. The multiscale fibril network with dynamic crosslinking achieves high strength (1.25 MPa), toughness (23.09 MJ m−3), and conductivity (1.51 S m−1), outperforming previous natural polymer ...

MACHOs, White Dwarfs, and the Age of the Universe

, 1997
(Abridged Abstract) A favored interpretation of recent microlensing measurements towards the Large Magellanic Cloud implies that a large fraction (i.e. 10--50%) of the mass of the galactic halo is composed of white dwarfs.
