Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Comparison of Numerical Simulation Techniques of Ballistic Ceramics under Projectile Impact Conditions

Materials, 2021
This article presents an analysis of the effectiveness of available numerical techniques in mapping the characteristic behavior of ballistic ceramics under projectile impact conditions. As part of the work, the ballistic tests were performed on the layered ceramic/steel composite armor and tested with the 7.62 × 39 mm, armor-piercing incendiary (API ...

Deep‐Tissue Light Generation via Whispering Gallery Mode Lasing From a Commercial Nylon Fiber for Biomedical Applications

Advanced Materials Technologies, EarlyView.
A dyed nylon fiber is implemented inside the scattering phantom and skin tissue. The deep‐tissue light generation via whispering gallery mode lasing is demonstrated, achieving a depth of >50 times transport mean free path in scattering phantom and 3 mm beneath skin.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,
