Graphene-based materials are widely used in the field of immobilized enzymes due to their easily tunable interfacial properties. We designed amphiphilic nanobiological interfaces between graphene oxide (GO) and lipase TL (Thermomyces lanuginosus) with reduction degrees through molecular dynamics simulations a facile chemical modulation, thus revealing optimal interface for activation addressing weakness TL, which exhibits weak catalytic activity an inconspicuous active site lid. It was...
This paper proposes a linear piezoelectric actuator with flexible mechanism wing skeletal structure. Besides the compact structure, high location precision and easy control, main innovation point is that through proposed solves problem existing actuators based on parasitic motion principle must sacrifice performance in one direction for improving opposite direction. The design process operation of elaborated. And finite element analysis software ABAQUS mathematical MATLAB/SIMULINK are used...
A novel chitosan-modified adsorbent (glutaraldehyde cross-linked chitosan biguanidine (GCB)) was prepared by the reaction of glutaraldehyde with hydrochloride. The characterized Fourier transform infrared, scanning electron microcopy, and thermogravimetric analysis. effects various variables for adsorption Cr(VI) on GCB were systematically investigated. results showed that equilibrium behavior had best agreement Langmuir isotherm model maximum capacity calculated as 202.4 mg · g−1 pH 3.6 at...
Abstract A cascade reaction involving a base-promoted nucleophilic substitution between diketones and α-bromoacetophenone derivatives the subsequent selective condensation–cyclization was developed for synthesis of 1,2-diaroyl benzofurans. 1,2-Diaroyl benzofurans with different functional groups structures exhibit reversible photochromic behaviors in solution, solid state, thin films diverse colors, demonstrating potential application field optical materials.
A modularized cryogenic indentation apparatus was designed and created to study the deformation mechanisms mechanical properties of materials at low temperatures. The process is actuated by piezoelectric stack flexure hinge, entire module kept inside vacuum chamber prevent occurrence ice. Numerous issues including effects application cooling processes diminish temperature effect on tip were addressed. Several influential factors during discussed. Tests calibration specimen demonstrated...
High-precision cryogenic micromechanical testing apparatuses are of significant importance in investigating the micro-region mechanical properties and deformation behaviors materials at temperatures. In this study, a modular indentation apparatus was designed developed utilizing contact-atmosphere hybrid refrigeration technique with minimum temperature −150 °C. The both indenter tip specimen independently controlled through dual-channel proportional–integral–derivative (PID) feedback loop to...
This paper compares three flexible mechanisms in parasitic motion principle piezoelectric actuator through analytic calculation and experiment investigation. The mechanism used can be classified into functional shape type asymmetrical stiffness type. For comparing the benefits of these two types their hybrid structure, relation between force displacement are deduced using matrix-based compliance modeling method. Also, dynamic model is to explore influence dimension mechanism. After that, a...
