Abstract The mechanical soft–hard transition of hydrogels is desired in conditions‐adaptive deformation and mechanics reconfiguration applications. However, highly efficient, stimuli‐responsive, reversible strategies are hard to achieve. Inspired by the supercooling salt‐aqueous solutions, solid supersaturated prepared based on a hydrophilic polymer network solution. inner crystallization‐ or melting‐induced phase‐change realizes switch between soft hydrogel (modulus: 0.1 MPa) rigid...
Purpose The purpose of this paper is to determine the ultra-high cycle fatigue behavior and ultra-slow crack propagation selective laser melting (SLM) AlSi7Mg alloy under as-built conditions. Design/methodology/approach Constant amplitude two-step variable tests were carried out using ultrasonic equipment. fracture surface failure specimen was quantitatively analyzed by scanning electron microscope (SEM). Findings results show that competition interior initiation modes leads a duplex S–N...
Three polypropylene (PP) matrixes with different intrinsic toughness were used to study the morphologies and mechanical properties of PP filled four sizes calcium carbonate particles. PP1 was a homopolymer, PP2 propylene-ethylene copolymer, PP3 mixture (PP1:PP2 = 1:1, weight ratio). Calcium (CC25, CC4, CC1.8, CC0.07) an average particle size 25, 4, 1.8, 0.07 μm, respectively, used. It clear that matrix filler had key effects on improvement matrix. For all three matrixes, yield strength,...
Microchannels have revolutionized fields such as chemical analysis, drug delivery, and diagnostics, by offering enhanced control over fluid flows at microscale dimensions. The behavior of fluids in microchannels, governed principles like viscous capillary forces, differs significantly from macroscopic flows, these differences implications for fluid–structure interaction well. Microchannel geometries often involve thin walls, making them susceptible to deformation under fluid-induced...
Abstract The rubber lining in a condensate polishing system of nuclear power plant exhibited significant blistering and cracking shortly after the operation, posing safety risk to chlorine storage tank. Extensive analysis, including thermal gravimetric infrared spectroscopy, mechanical testing, scanning electron microscopy, was conducted assess thoroughly. Subsequently, underwent 72-hour immersion test 31 % hydrochloric acid at 50°C evaluate its performance. results revealed that content...
Abstract The significance of nanoparticle shapes is evident in various domains detecting trace metals biomolecular assays and nanotechnology applications. present study focused on Copper Aluminum-water hybrid nanofluid flow inside a lid-driven cavity. heated elliptic-shaped obstacle emended the square contained water two categories nanoparticles with sphere, column lamina shapes. solution projected model governing equations evaluated by Galerkin Method. Long short-term memory used to ensure...
Fully acetylated poly(amidoamine) (PAMAM) dendrimer was proposed as a biocompatible drug vehicle using dexamethasone 21-phosphate (Dp21) model drug. NMR techniques including 1H and 2D NOE were used to characterize the host−guest chemistry of dendrimer/Dp21 cationic complexes. The pH-dependent micellization, complexation, inclusion behaviors Dp21 observed in presence PAMAM dendrimers. Acetylated only encapsulates at acidic conditions, while can host both neutral conditions. orientation...
Nickel-titanium (NiTi) is the most ordinarily used shape memory alloy (SMAs), which has important implications in aerospace, medical devices and so on. However, NiTi parts were limited their application scope ability due to difficulty of processing. Until appearance laser powder bed fusion (LPBF) technology, it overcame preparation's multiple challenges became preferred method fabricate alloy. Nevertheless, fabricated by LPBF that have a great shortage still exist corrosion resistance....
Abstract Three types of polypropylene (PP) with different intrinsic toughness were used to study the mechanical properties and morphologies PP composites filled single‐filler hybrid‐filler calcium carbonate particles. The particles average particle sizes 25 μm (CC25), 0.07 (CC0.07), respectively. A CaCO 3 named CC25/CC0.07 was as a mixture CC25 CC0.07 (CC25/CC0.07 weight ratio = 1:1). It found that type size inorganic filler two important factors for determination composites. And general...
The host−guest chemistry of dendrimer−biomacromolecule complexes is great significance to both design and optimization dendrimer-based drug delivery systems. Here, we characterized the interactions between dendrimer heparin by isothermal titration calorimetry (ITC), 1H nuclear magnetic resonance (1H NMR), pulsed-field gradient (PFG) NMR, Overhauser effect spectroscopy (NOESY), atomic force microscopy (AFM) studies. calorimetric results suggest that miscellaneous aggregates are formed at...
We studied the formation and growth of miscellaneous mixed micelles in dendrimer surfactant mixtures. NMR techniques including (1)H titration, diffusion (PGSE DOSY) measurement, NOE analysis were used to investigate shape, size, interaction mode, spatial localization, molecular orientation formed dendrimer/surfactant aggregates at different stages. The results suggest following supramolecular when an equal molar concentration sodium dodecylsulfate (SDS) deoxycholate (SDC) added into a...
