Flexible Selenium Nanowires with Tuneable Electronic Bandgaps

Advanced Materials, EarlyView.
Nanotubes serve as effective test tubes for selenium nanowires, as their diameter precisely controls the width of the nanowires and the Se─Se bonding, resulting in a variety of different structures. An electron beam can be used to modify the nanotubes, allowing real‐time observation of the nanowire extrusion process. Additionally, optically transparent

A characterization of convex function

Applied Mathematics Letters, 2000
AbstractIf C ⊆ Rn be a nonempty convex set, then f: C → R is convex function if and only if it is a quasiconvex function on C and there exists some α ∈ (0, 1) such that f(ax+1(1−α)y)≤αf(x)+(1−α)f(y), ∀x,y ϵC.

Organic–Inorganic Hybrid Indium Halide Perovskites with Near‐Unity Photoluminescence Quantum Yield

Advanced Materials Interfaces, EarlyView.
The intrinsic low photoluminescence quantum yield (PLQY) of organic–inorganic hybrid halide perovskites has limited their applications in optoelectronic devices. In this work, novel (PMA)₄InCl₇·0.5H₂O single crystals are developed and a PLQY of approximately 100% through optimized antimony ion (Sb3⁺) doping is achieved. The light‐emitting diodes (LEDs)

4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

Automatic Exposure Volumetric Additive Manufacturing

Advanced Materials Technologies, EarlyView.
Tomographic volumetric additive manufacturing (VAM) is resin‐based 3D printing technology, where objects are printed in seconds using volumetric light patterning. Although fast, tomographic VAM struggles to produce repeatable and accurate prints. This work demonstrates an automatic exposure method for tomographic VAM, resulting in commercial‐grade ...
