A No Mix sanitation system was installed in a dormitory at the University of Can Tho in Vietnam, with the objective of recycling nutrients from source separated urine. This paper presents a pilot scale evaporation technology, and investigates the feasibility of recovering nitrogen and phosphorus from human urine by solar still for use as fertilizer. After(More)
Trust is considered one of the most important factors for successfully managing software outsourcing relationships. However, there is lack of research into understanding the factors that are considered important in establishing and maintaining trust between clients and vendors. The goal of this research is to gain an understanding of software outsourcing(More)
Ultrathin (0.3-3 nm) metal dichalcogenides exhibit confinement of carriers, evolution of band-structure and photophysical properties with thickness, high on/off rectification (in MoS2, WS2, and so forth) and high thermal absorption. Here, we leverage the stable sulfur/nobel-metal binding to incorporate highly capacitive gold nanoparticles (Au NPs) onto MoS2(More)
By interfacing the quantum mechanical properties of nanomaterials with the complex processes in biology, several bio/nano systems have evolved with applications in biosensors, cellular devices, drug delivery, and biophotoluminescence. One recent breakthrough has been the application of graphene, a two-dimensional (2-D) sheet of sp(2) hybridized carbon atoms(More)
NIR polymethine cyanine dyes exhibit long wavelengths that cannot be detected by the naked eye, whereas normal biological tissues fluoresce in the visible region of the electromagnetic spectrum. Using FLARE (Fluorescence-Assisted Resection and Exploration) imaging technology, both visible and NIR light can now be superimposed and visualized simultaneously.(More)
Ultrasmooth hexagonal boron nitride (h-BN) can dramatically enhance the carrier/phonon transport in interfaced transition metal dichalcogenides (TMDs), and amplify the effect of quantum capacitance in field-effect gating. All of the current processes to realize h-BN-based heterostructures involve transfer or exfoliation. Rational chemistries and process(More)
Mammalian flavin-containing monooxygenase (FMO) is active towards many drugs with a heteroatom having the properties of a soft nucleophile. Thiocarbamides and thiones are S-oxygenated to the sulfenic acid which can either react with glutathione and initiate a redox-cycle or be oxygenated a second time to the unstable sulfinic acid. In this study, we(More)
Amphiphilic reduced graphene oxide is obtained by oleo-functionalization with epoxidized methyl oleate (renewable feedstock) using a green process. The excellent diverse solvent-dispersivity of the oleo-reduced amphiphilic graphene and its reduction chemistry are confirmed in this study. Oleo-reduction of amphiphilic graphene is amenable to industrially(More)
The nanoarchitecture and micromachinery of a cell can be leveraged to fabricate sophisticated cell-driven devices. This requires a coherent strategy to derive cell's mechanistic abilities, microconstruct, and chemical-texture towards such microtechnologies. For example, a microorganism's hydrophobic membrane encapsulating hygroscopic constituents allows it(More)
