Intraperitoneal adhesions are common and serious complications after surgery. Deposition of proteins inflammatory response on an injured cecum the main factors resulting in formation adhesion. In this study, purely zwitterionic hydrogels (Z-hydrogels) developed using thiolated poly(sulfobetaine methacrylate-co-2-((2-hydroxyethyl)disulfanyl)ethyl methacrylate) [poly(SBMA-co-HDSMA)] as network backbone divinyl-functionalized sulfobetaine (BMSAB) cross-linker via thiol–ene click reaction. To...
To improve the therapeutic effect of a hydrogel on damaged tissue, series hydroxybutyl chitosan (HBC) and poly(sulfobetaine methacrylate) (PSBMA) composite hydrogels (HBC-PSB) with thermosensitivity, self-healing, antibiofouling, synergistic antibacterial activity are prepared by mechanical blending. The electrostatic interaction among PSBMA hydrophobic association HBC main drive force to form full physically crosslinked hydrogel. can avoid aggregation precipitation caused intermolecular...
Understanding and revealing the evolution mechanism of columnar to equiaxed transition (CET) that occurred in laser direct energy deposition (LDED) fabricated medium-entropy alloys (MEAs) is crucial for achieving tunable microstructure mechanical properties. In present work, a CET map was established explain effect density (LED) on LDED single tracks CrCoNi MEA. The results show observed related morphological transformation cellular substructure, which governed by constitutional...
Peritoneal adhesions (PA) are a common and severe complication after abdominal surgery, impacting millions of patients worldwide. The use anti-adhesion materials as physical barriers is an effective strategy to prevent postoperative adhesions. However, the local inflammatory microenvironment exerts significant impact on efficacy therapies. In this study, injectable hydrogel based oxidized dextran/carboxymethyl chitosan (DCC) designed prepared. Furthermore, DCC specifically engineered load...
Healing large-scale wounds has been a long-standing challenge in the field of biomedicine. Herein, we propose an injectable oxidated sodium alginate/gelatin/3,3'-dithiobis(propionic hydrazide)-aurum (Alg-CHO/gelatin/DTPH-Au) hydrogel filler with asymmetric adhesion ability and removability, which is formed by Schiff-base reaction between aldehyde-based alginate multi-amino crosslinkers (gelatin DTPH), combined coordination interaction Au nanoparticles disulfide bond DTPH. Consequently,...
Technology readiness level is an assessment tool for technology risk control, widely used in large-scale complex engineering such as military and aerospace industries. High purity metal targets are one of the key materials required production fields semiconductors, flat panel displays, solar cells. The process very complex, which determines technological maturity will have a significant impact on downstream applications. This article combines needs users establishes evaluation model...
Abstract As the 630°C USC power units develops rapidly, two commonly employed austenitic steels HR3C and Super304H cannot be suitable with higher temperature pressure any more. Due to their poor steam oxidation resistance low strength, a new Austenitic heat-resistant steel 22Cr-15Ni-4Cu has been developed according strengthening mechanism of multiphase. The samples were aged for different times from 50h 5000h under 650°C. results show that Charpy impact energy sharply decreases in first...
Abstract In order to identify the corrosion properties of three kinds austenitic stainless steel used in solar power plant, experiments were conducted test weight loss after dynamic immersing molten salt, thickness rates per year was obtained, and surface morphology by SEM component corrosive product EDS analyzed. The result showed that resistance 316L 347H are outstanding, much better than 304. material is 304 <316L< 347H. can be considered as candidate materials low-temperature salt...
The system performance of the supercritical CO2 Brayton cycle for Sodium Fast Reactor with a partial-cooling layout was studied, and an economic analysis carried out. energetic, exergetic, exergoeconomic analyses are presented, optimized results were compared recompression cycle. sensitivity conducted by considering variations in pressure ratios inlet temperatures main compressor turbine. exergy efficiency reached 63.65% net power output 34.39 MW via optimization. obtained minimum total cost...
Abstract σ phase is one of the main precipitates affecting toughness austenitic stainless steel, V-notch impact test, SEM, EDS and TEM analysis were conducted on newly developed 22Cr15Ni3.5Cu steel after 650°C aging. Precipitation mechanism its effect material analyzed. The test results show that decreases to 25.6J 300h aging, started precipitate along grain boundary 500h in crystal 1000h precipitation spacing about 100 nm, forming a gradually increasing size from boundary. As time was later...
The effect of H + ‐ion irradiation on the structure and properties a Cu 50 Zr metallic glass (MG) is investigated. High‐energy synchrotron X‐Ray diffraction results indicate that maintains its amorphous nature after ion irradiation. As fluence increases, atomic bond length MGs becomes shorter, whereas nanohardness Young's modulus increase from 7.08 ± 0.01 111.3 1.1 GPa for as‐spun sample to 8.59 0.06 123.1 1.3 irradiated with 2 × 10 16 cm −2 fluence. corrosion potential studied MG in 1 mol L...
Abstract By means of optical microscope, SEM and EDS, the microstructure laser cladding layer under 1200W heat input was analyzed. Through research, relationship between precipitate characteristics properties studied, failure reason found. The results show that Co, Cr W elements have tendency short-range diffusion in surface region Stellite 6 alloy with a jagged shape. In this area, Co-Cr-W-Fe precipitated hardened formed high hardness abrasive resistance but lower ductility. Meanwhile,...
