This study investigates the effects of different pH environments on durability coir fiber-reinforced epoxy resin composites (CFRERCs). The CFRERCs were prepared by combining alkali-treated fibers with and exposing them to acidic, alkaline, pure water, seawater for a 12-month corrosion test. results show that an alkaline environment has most significant impact tensile strength CFRERCs, 55.06% reduction after 12 months. acidic causes 44.87% decrease in strength. In contrast, decreases 32.98%...
Yb³⁺/Er³⁺co-doped cubic-(α-) phase NaYF₄ nanocrystals were prepared through a microwave- assisted hydrothermal method. Temperature-dependent upconversion luminescence (UCL) and sensing properties systematically studied. It is interesting that anomalous temperature- dependent UCL behavior observed. With increasing temperature (303-573 K), the intensity of Er³⁺ does not quench monotonously but reaches minimum around 483 K then increases. However, it was found spectra change in different way...
Habitat management such as field- or farm-level diversification can conserve arthropod natural enemies, enhance biological pest control and lower (or suspend) insecticide use in agricultural crops. These approaches however have been underexploited to manage the aphid Aphis gossypii cotton cropping systems of Xinjiang, China. In this study, we investigated whether presence licorice (Glycyrrhiza uralensis) at field edge benefits generalist predator abundance local crops.Field trials during...
Tm³⁺/Yb³⁺ codoped NaY(WO₄)₂ microstructures with various Tm³⁺ concentrations and 10 mol% Yb³⁺ concentration were prepared by a microwave-assisted hydrothermal method, their upconversion luminescence (UCL) was investigated. Under excitation at 980 nm, exhibited strong blue near infrared (NIR) emissions, respectively, corresponding to ¹G₄ --> ³H₆ ³H₄ transitions, weak red emission due the transition. The optimum doping of for highest NIR UCL investigated, it found that optimal emissions 0.5...
Abstract Graphene‐based electromagnetic absorbing materials have attracted growing attention, due to their great absorption efficiency and light weight. One common design principle is load magnetic particles onto graphene. However, the agglomeration of nanoparticles on graphene sheets limits further improvement in performances. In this work, polyaniline/nano‐Fe 3 O 4 /graphene ternary hybrids with regulated multi‐interfaces are designed by simply adjusting adding order The dispersion nano‐Fe...
Unsteady dielectric barrier discharge (DBD) plasma aerodynamic actuation technology is employed to suppress airfoil stall separation and the technical parameters are explored with wind tunnel experiments on an NACA0015 by measuring surface pressure distribution of airfoil. The performance DBD for suppression evaluated under voltages from 2000 V 4000 duty cycles varied in range 0.1 1.0. It found that higher lift coefficients lower threshold achieved unsteady less than 0.5 as compared steady...
Memcached is a widely adopted, high-performance, in-memory key-value object caching system utilized in data centers. Nonetheless, its stored volatile DRAM, making the cached susceptible to loss during shutdowns. Consequently, cold restarts experience significant delays. Persistent memory byte-addressable, large-capacity, and non-volatility storage media, which can be employed avoid restart problem. However, deploying on persistent requires consideration of issues such as write endurance,...
The high geo-temperature is becoming a more common geological condition in tunnel and mining engineering, it urgent to prepare grouting materials possessing preferable properties adapt the geothermal environment.To develop an appropriate cement-based material through incorporating fly ash, slag powder superplasticizer, its simulated environment background of Gaoligong Mountain China were investigated.The orthogonal experiment was applied contrastively studied at 40 °C 20 °C,...
The favorable international and national environment conditions in the 1980s have led to initial formation of a triangular-shaped all-China economic (cooperation) sphere between mainland Taiwan province Hong Kong. In 1990, China as whole [that is, including Kong— ed.] had population 1.16 billion. Its foreign trade export were, respectively, over U.S. $400 billion $210 billion, surpassing Great Britain ranking fifth world after Germany, United States, Japan, France. exchange reserves amounted...
