Programming Neuromorphic Plasticity Through Ionic and Electronic Coupling in Organic Electrochemical Transistors

Advanced Functional Materials, EarlyView.
Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Lateral torsional buckling of an I‐shaped hoisting spreader beam

, 2021
I-shaped hoisting spreader beams are widely used in practice when lifting heavy objects by crane. In general, I-shaped beams that are subjected to a bending moment may be sensitive to lateral torsional buckling.

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.

SEISMIC RESILIENCE PERFORMANCE OF INNOVATIVE TORSIONAL DAMPER FOR STEEL MOMENT RESISTING CONNECTIONS

This study explores the enhancement of seismic performance in braced steel frames through the integration of a novel Torsional Steel-Tube Damper (TSTD). The primary objectives are to determine the optimal dimensions and configuration of the TSTD within brace-to-beam connections, assess its impact on the global and local seismic behavior of the ...

Differential Sedimentation and Cryo‐TEM Mapping Resolve Structural Heterogeneity in Conjugated Polymer Nanowires for Programmable Stretchable Electronics

Advanced Materials, EarlyView.
Density‐driven differential sedimentation fractionates solution‐assembled P3HT nanowires into crystalline and disordered constituents. High‐resolution cryo‐TEM directly visualizes the molecular chain packing within individual nanowires in real space, and recombining the fractions programs the mobility–stretchability trade‐off without chemical ...

Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

Advanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

Torsional Behavior of High-Strength Reinforced Concrete Beams

Journal of Engineering and Sustainable Development, 2013
Recent methods for torsional design of reinforced concrete beams tend to the use of space truss analogy, instead of the earlier skew bending theory. A total of (43) rectangular beams made of high strength concrete (HSC) that failed under pure torsion ...

Effect of Horizontal Stiffeners on the Efficiency of Steel Beams in Resisting Bending and Torsional Moments: Finite Element Analysis

Buildings
Steel beams with eccentric loads are subjected to combined bending and torsional moments that lead to lateral displacements, unwanted stresses at the top and bottom flanges, and global buckling along their length. To resist these displacements and stresses, horizontal stiffeners were used in the direction of the beam axis at locations of the beam’s web

Lateral-torsional buckling resistance of castellated beams

, 2017
The existing design expressions for the lateral-torsional buckling behavior of castellated beams conflict. Furthermore, they do not take into account the detrimental effect of the residual stress modification attributable to the fabrication process ...
