Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Effects of Sheet Thickness on the In-Plane Stretch Forming Limit in an Aluminum Sheet

JSME international journal. Ser. 1, Solid mechanics, strength of materials, 1988
An investigation concerning the effects of sheet thickness on the in-plane stretch forming limit in 1100 aluminum sheets with thicknesses of 0.5 to 1.0 mm prepared by electro-polishing have been carried out experimentally and analytically. Development of surface roughness is represented by linear relation between surface roughness and effective strain,

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

Controlling boundary layer separation in stretching sheet flow

Alexandria Engineering Journal, 2018
The effects of non-uniform nanoparticle concentration within the boundary layer flow due to stretching surface are analyzed by employing a non-homogeneous model of nanofluid which passively controls the concentration of nanoparticles at the surface.

Pressure‐Assisted Dimensional Transformation of 2D Hydrogenated Borophene into 0D Boron Quantum Dots

Advanced Functional Materials, EarlyView.
Hydrogenated borophene (HB) is transformed into distinct boron nanostructures through a solvent‐free thermal process. Under flowing nitrogen, hydrogen escape promotes reconstruction into B2O3 nanoplatelets, whereas hydrogen‐induced pressure under sealed conditions facilitates fragmentation into boron quantum dots.
