Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Structure and stability of a spherical shock wave in a Van der Waals gas [PDF]

The Quarterly Journal of Mechanics and Applied Mathematics, 1996
It is demonstrated that similarity solutions exist for spherically converging and diverging shocks in a van der Waals gas. These represent a generalization of the corresponding and well-known Guderley solutions for an ideal gas. For small van der Waals excluded volume, \(b\), there is only one branch of solutions, and this differs little from the ...

Unraveling MXene Oxidation Mechanisms Under Realistic Gas Environments by In Situ Gas‐Cell TEM

Advanced Functional Materials, EarlyView.
Real‐time visualization of MXene degradation reveals a fundamental oxidation mechanism under oxygen and moisture environments. Using in situ gas‐cell electron microscopy, this study demonstrates that oxygen degradation drives a thermodynamically controlled high‐temperature transformation into mixed rutile/anatase phases.

Interacting Quintessence Dark Energy Models in Lyra Manifold

Advances in High Energy Physics, 2014
We consider two-component dark energy models in Lyra manifold. The first component is assumed to be a quintessence field while the second component may be a viscous polytropic gas, a viscous Van der Waals gas, or a viscous modified Chaplygin gas. We also

Evolution of weak waves and central expansion waves in a non-ideal relaxing gas

Ain Shams Engineering Journal, 2016
The main features of small amplitude waves generated by a planar piston-like surface in a planar flow of a vibrationally non-ideal relaxing gas are investigated.

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|

Evolution of weak discontinuity in a van der Waals gas

Ain Shams Engineering Journal, 2015
In this article, the Lie symmetries analysis that leaves the system of partial differential equations (PDEs), governed by the one dimensional unsteady flow of an isentropic, inviscid and perfectly conducting compressible fluid obeying the van der Waals equation of state invariant, is presented.

Mechanical Instabilities and the Mathematical Behavior of van der Waals Gases

Mathematics
We explore the mathematical behavior of van der Waals gases at temperatures where classical descriptions are inadequate due to emerging quantum effects.

Janus Photonic Graphics by Stratified Assembly of Two Distinct Colloids

Advanced Functional Materials, EarlyView.
Double‐sided Janus photonic micropatterns with vivid structural colors are fabricated through a single‐step bottom‐up strategy. Density‐driven stratification and depletion‐mediated crystallization of PMMA and PS binary colloids lead to exclusive lattices on opposite surfaces under centrifugal force.

The van der Waals interactions in rare-gas dimers: the role of interparticle interactions [PDF]

Physical Chemistry Chemical Physics, 2016
We investigate the potential energy curves of rare-gas dimers with various ranges and strengths of interparticle interactions (nuclear–electron, electron–electron, and nuclear–nuclear interactions).
