Development and Laboratory Evaluation of a Cold Mix High-Early-Strength Epoxy Asphalt Concrete for Steel Bridge Deck Pavements.

Epoxy asphalt concrete (EAC) is a widely used steel bridge deck pavement (SBDP) material. Due to the curing reaction, the EAC-based material needs a long curing period before opening to traffic, which in an inconvenience in the construction of SBDP. This study developed a cold mix high-early-strength (CHES) epoxy asphalt through the design of a compatilizer and curing agent system.

Effect of ultrasonic treatment of palygorskite on the catalytic performance of Pd-Cu/palygorskite catalyst for room temperature CO oxidation in humid circumstances.

Pd-Cu/palygorskite catalysts were prepared by a wet impregnation method using palygorskite (PC/N-Pal) and ultrasonic-treated palygorskite (PC/U-Pal) as the support. Their catalytic activities toward CO oxidation at room temperature and in humid circumstances were investigated. PC/U-Pal exhibits much higher catalytic activity and stability than PC/N-Pal under the conditions of 1.

[Chemiluminescent detection of E. coli O157:H7 in food based on magnetic enzyme-linked immuno method].

Aim: To establish a new chemiluminescent assay with high sensitivity for detecting E. coli O157:H7 in food.

Methods: The assay was established based on the alkaline phosphatase (ALP) labeled anti-E.

Magnetically actuated micromixing on an array-pattern microfluidic chip for immunoassay of human thyrotropin.

A novel array-pattern ring microfluidic chip has been designed and fabricated with ITO glass, and a low-cost, easy-to-use active magnetic mixer is developed. The mixer consists of externally driven magnetic stir plates and ferromagnetic microneedles as active mobile stirrers in the microchannel. Mixing performance in the microfluidic chip has been experimentally characterized by chemiluminescence immunoassay of human thyrotropin (TSH) and compared with tube-based chemiluminescence immunoassay.

[A novel microbeads-based chemiluminescence immunoassay for detecting human thyrotropin].

Aim: To establish a low cost and sensitive microbeads-based chemiluminescence immunoassay (CLEIA) for detecting human thyrotropin.

Methods: Thyrotropin in sera was captured by an alkaline phosphase-labeled mAb against TSH beta subunit and a FITC-labeled mAb against TSH alpha subunit. Captured thyrotropin was then isolated with immuno-magnetic beads conjugated with anti-FITC antibody and then quantified by chemiluminescence using adamanatane amine as luminescent substrate.
