The composite solid-state electrolytes are gathering significant attention for combining both the advantages of inorganic and polymer electrolytes. However, after years' research, conventional ceramic fillers offer limited ion conductivity enhancement in due to space charge layer that exists between matrix phase. In this study, we develop a ferroelectric ion-conductor (LiTaO<sub>3</sub>) as functional filler alleviate provide extra Li<sup>+</sup> transport pathway tandemly. obtained...
A strategy to manipulate the disulfide bond breaking triggered unfolding, and subsequently assembly of human serum albumin (HSA) in a lipophilic drug-dependent manner is present. In this study, hydrophobic region, molecular switch HSA, was regulated form HSA-paclitaxel (HSA-PTX) nanoparticles by facile route. High-resolution transmission electron microscopy fluorescence quenching indicate that HSA coassembled with PTX, which acts as bridge core-shell about 50-240 nm size, PTX might bind...
Microbial-induced calcium carbonate precipitation (MICP) technique takes advantage of the metabolic process bacteria bonding soil particles together with an environmentally-friendly and sustainable manner. In this study, powder activated carbon-fiber felt (ACFF) scrap was utilized MICP to improve strength, six different ACFF ratios (0%, 0.2%, 0.6%, 1%, 1.4%, 2% by weight) were adopted. Unconfined compressive strength (UCS) splitting tensile (TS) tests carried out for evaluating effect on dry...
Polymer-blend geocell sheets (PBGS) have been developed as substitute materials for manufacturing geocells. Various attempts made to test and predict the behaviors of commonly used geogrids, geotextiles, geomembranes, However, elastic-viscoplastic novel-developed are still poorly understood. Therefore, this paper investigates PBGS gain a comprehensive understanding their mechanical properties. Furthermore, tensile load-strain history under various loading conditions is simulated by numerical...
Urease is involved in the formation of carbonate sediments by microbial-induced calcium precipitation (MICP), and Sporosarcina pasteurii used extensively this technique owing to its high urease production. In study, a simple two-step culture method with appropriate medium was developed enhance activity S. pasteurii. Urea played an important role process, particularly during pre-cultivation step newly improved both specific activity. Furthermore, increase MICP resulted increased production...
Microbial-induced calcium carbonate precipitation (MICP) is a new soil remediation technology, which can improve the physical and mechanical properties of by transporting bacterial solution cementation to loose precipitating between particles through microbial mineralization. Based on this technique, effects different fine particle content pore ratio chemical silt after reinforcement were studied. The carbonate, ability fixed bacteria, unconfined compressive strength (UCS), permeability...
Microbial-induced calcium carbonate precipitation (MICP) is a new technology used for reinforcing soils through microbial mineralization. However, the existing MICP treatment more suiTable deeper due to its high permeability. In this study, HPMC, cohesive material combined with Sporosarcina pasteurii-induced was improve surface layer of soil. It also tested in different contents bacterial solutions and cementation number treatments, analyzed discussed by measuring strength, content generated...
The effects of the initial void ratio and grain size distribution (GSD) on water retention properties a compacted infilled joint soils from Beihetan (China) were investigated. Three ratios (0.3, 0.4, 0.5) three GSDs selected based in situ soil states. A total nine drying curves (WRCs) was established with filter paper method. microstructure specimens also studied to better understand properties. It found that denser samples underwent smaller volume changes, volumetric strain increased...
Ring shear tests were carried out on a compacted low-plasticity infilled-joint soil from Beihetan site in China. Different initial water contents (5·0, 9·0 and 13·5%) considered. It was observed that the failure envelope is linear for peak deviator stress but highly non-linear residual range of high normal stresses (higher than 400 kPa), evidencing particle crushing effect strength. Furthermore, this dependent content: friction angle larger at higher content. Further grain size analysis...
