There have been great concerns about the persistence of steroid hormones in surface water. Since the concentrations of these compounds in water samples are usually at a trace level, the efficient… Expand
Dynamic response of concrete pavement structure with asphalt isolating layer under moving loads
Abstract: A three-dimensional finite element model (3D FEM) is built using ABAQUS to analyze the dynamic response of a concrete pavement structure with an asphalt isolating layer under moving loads.… Expand
Chitosan Hydrogel-Capped Porous SiO2 as a pH Responsive Nano-Valve for Triggered Release of Insulin
A pH responsive, chitosan-based hydrogel film is used to cap the pores of a porous SiO2 layer. The porous SiO2 layer is prepared by thermal oxidation of an electrochemically etched Si wafer, and the… Expand
Macroporous chitosan layer coated on non-porous silica gel as a support for metal chelate affinity chromatographic adsorbent.
A new immobilized metal affinity chromatography (IMAC) matrix was prepared by coordinating Cu2+ with cross-linked chitosan coated on non-porous silica gel (Cu-CTS-SiO2). Macroporous structure could… Expand
Causes of phytotoxicity of metsulfuron-methyl bound residues in soil.
The bioavailability and phytotoxicity of bound residues of metsulfuron-methyl were studied using 14C-labeling and bioassay with oil rape (Brassica napus L.). Soil bound residues at the concentration… Expand
Preparation and Characterization of the Fluorescent Chitosan Nanoparticle Probe
Abstract The chitosan (CS) nanoparticles were prepared by crosslinking low-molecular weight chitosan with polyanion sodium tripolyphosphate (TPP). The fluorescent chitosan nanoparticles (FCNP) could… Expand
Novel nylon-supported organic-inorganic hybrid membrane with hierarchical pores as a potential immobilized metal affinity adsorbent.
Chitosan-based porous organic-inorganic hybrid membranes supported by microfiltration nylon membranes were prepared, in which gamma-glycidoxypropyltrimethoxysilane (GPTMS) was used as an inorganic… Expand
miR-340-FHL2 axis inhibits cell growth and metastasis in ovarian cancer
Although increasing evidence indicated that deregulation of microRNAs (miRNAs) contributed to tumor initiation and progression, but little is known about the biological role of miR-340 in ovarian… Expand
Rapid antibiotic susceptibility testing in a microfluidic pH sensor.
For appropriate selection of antibiotics in the treatment of pathogen infection, rapid antibiotic susceptibility testing (AST) is urgently needed in clinical practice. This study reports the… Expand
