The effect of citric acid on the structural properties and cytotoxicity of the polyvinyl alcohol/starch films when molding at high temperature
Abstract A series of starch/polyvinyl alcohol (PVA) films, denoted SP films, with varying concentrations (5–30 wt%) of citric acid (CA) were solvent cast at 140 °C. The effects of CA on the chemicalExpand
Rb-Sr, Sm-Nd, and Pb isotope systematics of pyrite: Implications for the age and genesis of lode gold deposits
Lode gold deposits commonly consist of pyrite and lesser amounts of lead and zinc sulfides accompanied by quartz and calcite. Their exact origin remains controversial mainly because of the scarcityExpand
Influence of high-frequency ambient pressure pumping on carbon dioxide efflux from soil
We report measurements at 2 Hz of pressure fluctuations at and beneath the soil in an agricultural field with dry soil and no vegetation. The objective of our study was to examine the possible roleExpand
The Rb-Sr isochron of ore and pyrite sub-samples from Linglong gold deposit, Jiaodong Peninsula, eastern China and their geological significance
Here we report the first direct Rb-Sr dating of pyrites and ores using sub-sampling from lode gold deposits in Linglong, Jiaodong Peninsula, which is a supra-large lode gold deposit and propose thisExpand
Synthesis and Characterization of Chlorpyrifos/Copper(II) Schiff Base Mesoporous Silica with pH Sensitivity for Pesticide Sustained Release.
TLDR
The experimental results showed that the larger the concentration of the copper ion, the more adsorption capacity (AC) of Cu-MCM-41 for chlorpyrifos and the smaller its release rate. Expand
Synthesis of Nano-Zinc Oxide Loaded on Mesoporous Silica by Coordination Effect and Its Photocatalytic Degradation Property of Methyl Orange
TLDR
The results confirmed that nano ZnO was loaded in the channels as well as the outside surface of mesoporous silica (MCM- 41) and the modification of salicylaldimine helped MCM-41 to load more nano ZNO on MCM -41. Expand
Synthesis, characterization, and comparison of antibacterial effects and elucidating the mechanism of ZnO, CuO and CuZnO nanoparticles supported on mesoporous silica SBA-3
Silanized iminodiacetic acid (GLYMO–IDA) modified mesoporous silica (G-SBA) was prepared following a co-condensation method. G-SBA/Cu2+, G–SBA/Zn2+ and G-SBA/Cu2+–Zn2+ were obtained through theExpand
Enzyme and pH dual-responsive avermectin nano-microcapsules for improving its efficacy
TLDR
Preparation of carboxymethyl cellulose grafting dimethyldiallylammonium chloride through grafting polymerization and trapping as well as encapsulation of avermectin (AVM) via electrostatic interactions resulted in the formation of AVM/CMC-g-PDMDAAC microcapsules. Expand
Preparation of pH-responsive avermectin/feather keratin-hyaluronic acid with anti-UV and sustained-release properties.
TLDR
In an effort to improve the utilization of pesticides, an environmentally friendly carrier material was prepared to encapsulate pesticides and to prevent pesticides from decomposing under natural conditions with sustained-release effect to show that AVM/FK-HA featured an average particle size and was capable of homogeneous dispersion.
