Experimental and simulated research on the ballistic performance of Ti/AlTi laminate composites

Advanced Composites Letters, 2020
The metal-intermetallic laminate composite Ti/Al 3 Ti can be used as protective armor in aerospace and military applications, due to its low density, high strength, and superior impact-resistant performance.

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

Advanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Ionic Liquid (IL) Compatibilization of Macropore‐Infused Nanocomposite Emulsion Thermosets (MINETs) for Structural Ion Transport

Advanced Materials Interfaces, EarlyView.
Macropore‐infused nanocomposite emulsion thermosets (MINETs) offer tunable multifunctionality due to their incorporation of structural resin, functional nanoparticles, and working fluid stabilized by surfactant. Here we show that if ionic liquid working fluids are introduced, structural capacitive (conductive particles) or separator (insulating ...

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,
