More than half of the recognized genera of positive strand RNA viruses employ polyprotein processing as one of the strategies for their genome expression. Normally, this processing is mediated by virus-encoded proteinases that belong to the trypsin-like or papain-like family. In particular, papain-like, leader proteinases were found in diverse families...
Early childhood is a crucial time for the holistic development of a child’s social, emotional, cognitive, and physical needs to build a solid and broad foundation for lifelong wellbeing and learning (Irwin et al., 2007). During this critical period, there is an increased demand for motor skills and executive function...
Metal-Organic Frameworks (MOFs) are crystalline compounds formed from reacting a metal ion with an organic ligand. They represent a promising new avenue in materials science for gas separations and storage. Certain MOFs, in particular Mg-MOF-74, have shown a strong affinity for the capture of CO2. This project investigated a known...
Transparent and electrically conductive metal oxide nanoparticles have attracted much attention, and can be used to improve the performance of solar cells, transparent electrode materials, and gas sensor technology. Specifically, indium tin oxide (ITO) nanocrystals (NCs) are potentially useful nanomaterials, having technological applications in enhanced sensitivity of optical spectroscopy due...
ZIF-8, a zeolitic imidazolate framework that consists of zinc ions and imidazolate linkers, is of great interest due to its simple synthesis methods, low-cost raw materials, chemical and thermal stability, as well as its stability in moist environments. Furthermore, due to its unique structure, it contains well-defined pores that have...
As a group of promising semiconductor materials, metal chalcogenides in thin film form have been widely used in electronics and optoelectronics applications, such as solar cell devices and photon sensors. Unfortunately, the film size and product throughput are limited by the current vacuum-based thin film deposition techniques. Solution-based thin film...
There is an emerging interest in developing wearable electronics as a platform, which
provides the flexibility of a wearable while maintaining its promising functionality as smart textiles. Metal-halide semiconductors are attractive materials with tunable optical and electrical properties. Researchers have widely studied and applied it for advanced
photonics and optoelectronic...
The continuous microreactor-assisted solution deposition (MASD) process was used for the deposition of CdS thin films on fluorine-doped tin oxide (FTO) glass. The MASD system, including a T-junction micromixer and a microchannel heat exchanger is capable of isolating the homogeneous particle precipitation from the heterogeneous surface reaction. The results show...

Copper sulfides (Cu[subscript x]S) are compound semiconductor materials that exhibit considerable optical and electrical properties varying significantly as a function of the composition. Copper sulfide thin films can be used in many applications, such as solar control coatings, solar cells, photothermal conversion of solar energy, electroconductive coatings, and microwave shielding...
A unique microreactor-assisted nanomaterial synthesis and printing process was studied for the fabrication of patterned metal oxide nanostructured thin films. The process uses a continuous flow microreactor to control and generate a reactive chemical flux that was transported to a patterned microfluidic channel. The microreactor-assisted nanomaterial synthesis process can generate...
