A Highly Compact Zip Chain Arm with Origami-Inspired Folding Chain Structures [PDF]

open access: yesBiomimetics, 2023
A deployable robotic arm can be a useful tool for mobile systems to widen accessible areas without removing mobility. For practical use, the deployable robotic arm needs to satisfy two requirements: a high extension–compression ratio and robust ...

Investigation on Mechanical Properties and Oxidation Behavior of 1.2 and 1.7 GPa Grades Coating-Free Press-Hardened Steels

open access: yesMetals, 2023
Al-Si-coated boron-alloyed steels are the most widely used press-hardened steels (PHSs), which offers good oxidation resistance during hot forming due to the presence of the near eutectic Al-Si coating. In this study, a recently developed novel un-coated

Topological links in predicted protein complex structures reveal limitations of AlphaFold

open access: yesCommunications Biology, 2023
AlphaFold is making great progress in protein structure prediction, not only for single-chain proteins but also for multi-chain protein complexes. When using AlphaFold-Multimer to predict protein‒protein complexes, we observed some unusual structures in ...

Enumeration and comprehensive in-silico modeling of three-helix bundle structures composed of typical αα-hairpins

open access: yesBMC Bioinformatics, 2021
Background The design of protein structures from scratch requires special attention to the combination of the types and lengths of the secondary structures and the loops required to build highly designable backbone structure models.

Facile Synthesis of 3-(Azol-1-yl)-1-adamantanecarboxylic Acids—New Bifunctional Angle-Shaped Building Blocks for Coordination Polymers

open access: yesMolecules, 2019
For the first time, orthogonally substituted azole-carboxylate adamantane ligands were synthesized and used for preparation of coordination polymers. The angle-shaped ligands were prepared by the reaction of 1-adamantanecarboxylic acid and azoles (1H-1,2,

Shear Elasticity of Magnetic Gels with Internal Structures

open access: yesSensors, 2018
We present the results of the theoretical modeling of the elastic shear properties of a magnetic gel, consisting of soft matrix and embedded, fine magnetizable particles, which are united in linear chain-like structures.

NON-STATIONARY THERMAL CONDUCTIVITY OF CHAIN STRUCTURES AT LOW TEMPERATURES

open access: yesТонкие химические технологии, 2017
The matter of thermal conductivity is considered in an approximation, in which the free length of phonons is limited and doesn't depend on temperature, so that the temperature behavior of thermal conductivity coefficient is only determined by thermal ...

Restrain Price Collusion in Trade-Based Supply Chain Finance

open access: yesComplexity, 2021
Collusion can increase the transaction value among supply chain members to obtain higher loans from supply chain finance (SCF) service provider, which will bring some serious risks for SCF.
