Pressure has a significant effect on rubber seal performance in the abrasive environments of drilling. The micro-clastic rocks intruding into interface are prone to fracture, which will change wear process and mechanism, but this is not yet known at present. To explore issue, tests were carried out compare failure characteristics particles variation under high/low pressures. results show that non-round fracture different pressures, resulting damage patterns loss surface. A single particle...
Abstract Dynamic wound care presents significant challenges for conventional dressings due to the complex environment and high‐frequency motion associated with such injuries. In this study, a multifunctional photo‐crosslinked piezoelectric hydrogel (OAPS) is developed, incorporating heterojunction Se‐doped KH570 modified BaTiO 3 nanoparticles (Se‐BT570 NPs) as core component, designed address antimicrobial monitoring needs in care, particularly at sites movement. The OAPS effectively...
Anti-tuberculosis drug-induced liver injury (ATB-DILI), caused by first-line anti-tuberculosis (anti-TB) drugs, disrupts treatment and increases the risk of drug resistance. The gut microbiota intestinal barrier integrity play key roles in ATB-DILI susceptibility through liver-gut axis. Probiotics, such as Bacteroides fragilis 839 (BF839), have shown therapeutic potential modulating inflammatory responses. In this study, we investigated protective effects BF839 on a mouse model HRZE-induced...
Infection with Helicobacter pylori (H. pylori) is a primary etiological factor for chronic gastritis, peptic ulcers, and gastric cancer. The limited specificity of antibiotics against H. pylori, combined the risk severe adverse events from endoscopic submucosal dissection (ESD), presents major global health challenge in treating mucosal injuries. To address this issue, we developed targeted antibacterial hydrogel based on charge-reversal amphiphilic molecule, designed harsh acid environment...
The presence of particles leads to varying degrees mass loss on a metal sealing surface, which severely affects the seal’s lifespan. Understanding complex wear mechanism and optimizing surface roughness morphology are particularly important in engineering. By characterizing (SS 304) with different parameters Ra, Rp, Rpk, Rpc Rku, variation mode under abrasive conditions was revealed. Unlike traditional two-body wear, involvement significantly impacts Ra other morphologies (asperity peak...
Abstract To better understand the damage failure mechanism of ultra‐high molecular weight polyethylene (UHMWPE) in engineering application environments, a study was conducted to explore effect rotation speed on its abrasive wear performance lubricant media containing particles, especially comparison water. The analyzed by friction coefficient and behavior. results show that UHMWPE has excellent tribological properties water is seriously worn environment. Under condition wear, there exists...
Ischemia stroke is thought to be one of the vascular risks associated with neurodegenerative diseases, such as Alzheimer's disease (AD). Hydroxysafflor yellow A (HSYA) has been reported protect against and AD, while underlying mechanism remains unclear. In this study, SH-SY5Y cell model treated oxygen-glucose deprivation/reperfusion (OGD/R) was used explore potential HSYA. Results from counting kit-8 (CCK-8) showed that 10 μM HSYA restored viability after OGD 2 hours/R 24 hours. reduced...

Abstract Surface roughness characteristics are considered to be important in influencing wear performance, with asperity peaks being among the more influential. Changes removal mechanism were explored at microscopic level through friction experiments, revealing reasons for changes macroscopic amount. The show different forms of under metal surface characteristics. At low it is mainly removed as a whole and high partially. In addition, ranges parameters Ra Rpk, which have excellent...
Abstract Abrasive wear is one of the main causes rapid deterioration rubber serviceability. Therefore, it necessary to obtain information on degree abrasion and mechanism. Due complex nature abrasive surfaces, obtaining accurate often difficult provides limited quantitative parameters. This study presents a method quantify through defect detection analysis. Accurate fast identification typical defects achieved, in addition, macro- microscopic characterization data are provided based...
Abrasive wear results in inadequate life and reliability of FKM O-Ring dynamic seals. It is due to the fact that particles invasion difficult avoid under severe downhole conditions. To investigate relationship with assembly parameters properties, work about into sealing interfaces was initiated. Displacement Model for particle developed examined feasibility. In-situ observations at different sizes compression rates were carried out. Theory tests presented matching results, significantly...
Particles invasion into sealing interface is difficult to avoid in downhole conditions, which directly induces the failure of FKM O-ring dynamic seals. To enhance performance hard/soft seals particles environment, work on has been initiated. A displacement model for was developed and tested. In-situ observations were used investigate process under different sizes assembly compression rates. Theory tests showed matching results that rates had significant effects invasion. In addition, a...
The invasion behavior of particles in the drilling fluid under vibration conditions may lead to sealing failure more easily. A test rig was designed simulate operating condition FKM O-rings and environment. In-situ observations were also performed. results showed that two boundaries movement displacement would jointly into interface. It shown both behaviors induced by their salience influenced effect frequency vibration. new method study this problem proposed.
