ABSTRACT The photoisomerization behavior of mesogenic azobenzene makes it possible to convert light energy into mechanical action. However, achieving durability, configurability, and flexibility light‐responsive actuators for artificial intelligence applications remains challenging. Here, a responsive polyurethane (AzoPU‐SS) with remarkable anti‐fatigue anti‐stress properties has been synthesized through the combination dynamic disulfide bonds functional groups. AzoPU‐SS film demonstrated...
Abstract Intelligent actuating materials have drawn enormous attention because of their potential applications in soft robots, smart sensors, bionics, etc. Aiming to integrate light, thermal, and humidity stimuli deformations self‐healing function into a single polymer, polyurethane material CPPU‐50 is designed successfully synthesized through co‐polymerization azobenzene‐containing Azo‐C 12 , polyethylene glycol 200 (PEG200), 4,4'‐diphenylmethane diisocyanate (MDI) at ratio 1:1:2. The...
Septic shock is one of the major healthcare problems, affecting millions people around world every year. The object this study to find best kind regimen vasopressors treatment in septic shock.The PubMed, and Web Science were used included studies. Stata 15.1 was performed systemic review network meta-analysis.After searching screening articles, finally we articles about 31 randomized controlled trials (RCTs), 11 arms (dopamine, dopexamine, epinephrine, norepinephrine, norepinephrine +...
CuO/CNT composites were synthesized via simple and rapid microwave approach. The nanocomposites characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) photoelectron spectroscopy (XPS). Further, the electrochemical performances of evaluated. prepared samples displayed high specific capacitances 164.5[Formula: see text]F[Formula: text]g[Formula: text] at 1[Formula: text]A[Formula: text], during cycle process, capacitance value aggrandized to 274.7[Formula: remained 166%...
Strain gages and dynamic caustics were used in this experiment to measure the V-notch crack initiation toughness propagation of polymethyl methacrylate (PMMA) specimens. Furthermore, a method pasting strain on PMMA specimens for three-point bending test was proposed. The divided into five groups according opening angle (ω), each group corresponded two methods: acute-angle obtuse-angle method. results notch stress intensity factors (NSIFs) obtained by gage measurement consistent with...
Abstract The purpose of this paper is to study the dynamic fracture mechanics characteristics and fracturing behavior cracked-straight-through flattened Brazilian disk specimens using Split Hopkinson Pressure bar system. researchers also used Particle Flow Code 2D for simulating crack process achieved consistent outcomes. In experiment, rock were made from Beijing Fangshan granite. results experiment determined effects impact pressures loading angles on mode mechanical properties specimens....
Abstract Crack behavior at the interface between two materials is core problem of layered material fracturing. In this paper, first, experimental tests were conducted on using a drop weight test system following caustics method. The was made poly (methyl methacrylate) (PMMA) and epoxy resin bonded with Loctite‐330 inclination angles (30° 60°). A corresponding numerical simulation carried out continuum–discontinuum element methods. propagation found to mainly occur in mode I PMMA but follows...
