Spun-wrapped aligned nanofiber (SWAN) lithography for fabrication of micro/nano-structures on 3D objects
(Royal Society of Chemistry, 2016-06-01)Fabrication of micro/nano-structures on irregularly shaped substrates and three-dimensional (3D) objects is of significant interest in diverse technological fields. However, it remains a formidable challenge thwarted by ... -
Molecular basis of 5-hydroxytryptophan synthesis in Saccharomyces cerevisiae
(Royal Society of Chemistry, 2016-03-18)We report for the first time that 5-hydroxytryptophan can be synthesized in Saccharomyces cerevisiae by heterologously expressing prokaryotic phenylalanine 4-hydroxylase or eukaryotic tryptophan 3/5-hydroxylase, together ... -
A human exposome framework for guiding risk management and holistic assessment of recycled water quality
(Royal Society of Chemistry, 2016-04-12)Challenges associated with water scarcity and increasing water demand are leading many cities around the globe to consider water reuse as a step towards water sustainability. Recycled water may be used in a spectrum of ... -
Long-term performance of a 200 liter modularized microbial fuel cell system treating municipal wastewater: treatment, energy, and cost
(Royal Society of Chemistry, 2016-02-04)Microbial fuel cells (MFCs) have been intensively studied at a bench scale and the further development of this technology requires system scaling up and understanding of their performance under non-laboratory conditions. ... -
Aggregation and sedimentation of magnetite nanoparticle clusters
(Royal Society of Chemistry, 2016-03-24)Magnetite nanoparticles are redox active constituents of subsurface and corrosive environments. In this study, we characterized the aggregation and sedimentation behavior of well characterized magnetite nanoparticle clusters ... -
Highly stable SERS pH nanoprobes produced by co-solvent controlled AuNP aggregation
(Royal Society of Chemistry, 2016-04-22)Production of gold nanoparticle (AuNP) surface-enhanced Raman spectroscopy (SERS) nanoprobes requires replicable aggregation to produce multimers with high signal intensity. Herein, we illustrate a novel, yet simple, ... -
Acoustofluidic particle trapping, manipulation, and release using dynamic-mode cantilever sensors
(Royal Society of Chemistry, 2016-11-23)We show here that dynamic-mode cantilever sensors enable acoustofluidic fluid mixing and trapping of suspended particles as well as the rapid manipulation and release of trapped micro-particles via mode switching in liquid. ... -
DroidCat: Unified Dynamic Detection of Android Malware
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2016), TR-17-01Various dynamic approaches have been developed to detect or categorize Android malware. These approaches execute software, collect call traces, and then detect abnormal system calls or sensitive API usage. Consequently, ... -
