Highly Stable Low‐Temperature Phosphate Glass as a Platform for Multimaterial 3D Printing of Integrated Functional Microfluidic Devices

Advanced Engineering Materials, EarlyView.
A highly stable, low‐temperature phosphate glass is developed for multimaterial additive manufacturing of multifunctional microfluidics. Glass, metal conductors, and sacrificial polymer are coprinted, enabling monolithic fabrication. The sacrificial paste forms precise channels and decomposes during sintering.

Fluorescence spectroscopy of osthole binding to human serum albumin

Journal of Pharmaceutical Analysis, 2013
The interaction of human serum albumin (HSA) with osthole was investigated by fluorescence spectroscopy. Osthole can quench the fluorescence of HSA and the quenching mechanism is a static process. The binding site number n and apparent binding constant K

Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

Advanced Engineering Materials, EarlyView.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.

Iron specificity of a biosensor based on fluorescent pyoverdin immobilized in sol-gel glass

Journal of Biological Engineering, 2011
Two current technologies used in biosensor development are very promising: 1. The sol-gel process of making microporous glass at room temperature, and 2. Using a fluorescent compound that undergoes fluorescence quenching in response to a specific analyte.

Sensing of iron(III)-biomolecules by surfactant-free fluorescent copper nanoclusters

Sensing and Bio-Sensing Research, 2019
Surfactant-free copper nanoclusters (sf-CuNCs) synthesized in the absence of external stabilizer, could be promising fluorescence biosensors because of the presence of relatively exposed surfaces that may ease coupling with biomolecules.
