Durable Physically Mixed Microporous and Mesoporous MOFs/Nanofiber Aerogel 3D Composites for Effective Toxic Gas Capture and Organophosphonate Detoxification

Advanced Functional Materials, EarlyView.
Ultralight 3D nanofibrous aerogels embedded with metal‐organic frameworks effectively capture and neutralize toxic gases and organophosphonates. Incorporating mesoporous UiO‐66‐NH2 and HKUST‐1 into PAN/PVP fibers enables high MOF loading while maintaining mechanical strength and structural stability.

Charge‐Induced Morphing Gels for Bioinspired Actuation

Advanced Functional Materials, EarlyView.
This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...

Charge-transfer induced large nonlinear optical properties of small Al Clusters: Al4M4

, 2004
We investigate the linear and nonlinear electric polarizabilities of small Al4M4 (M=Li, Na and K) clusters. Quantum chemical calculations reveal that these compounds exhibit an exceptionally high magnitude of linear and nonlinear optical (NLO ...

Theoretical screening into urea-based receptor as a promising toxic gas sensor upon SO2, NH3 and H2S

Chemical Physics Impact
The adsorption of toxic gases such as NH3, SO2, H2S, on 1,3 bis (4-nitrophenyl) urea (BNPU) was investigated via the M062X/6–311++ g (d, p) level of theory to evaluate the utility of BNPU-based gas sensors.
