Malodor is an important class of air pollution that poses a serious threat to personal health and quality of life. Ammonia gas is a major cause of malodor complaints and is produced by microbial decompositions of organic wastes. A catalyst capable of attaining better than 99 % conversion of 50 ppm NH3 in air at room temperature was successfully prepared. The EA of the reaction is dramatically decreased by using the catalysts when the ratio of VOx/TiOx increases. The NH3 was oxidized to nitrogen and water during the reaction without producing NOx. The catalyst was characterized by BET, micro-Raman and X-ray photoelectron spectroscopy to identify the active sites to be monomeric VOx on TiOx. © Copyright American Institute of Chemical Engineers.

The growing shortage of freshwater resources has spurred the development of innovative and sustainable desalination technologies. This study presents a thermo-economic analysis of an innovative hemispherical solar still (HSS) enhanced with a novel Metal-Organic Framework (MOF), specifically Iron-Aluminum Benzene Tricarboxylate. The MOF was characterized through structural, morphological, and optical investigations and integrated into the HSS using two enhancement methods: (I) as a nanofluid (MOF-NF) at a 1 wt% concentration in the feedwater, and (II) as a heat localization material (MOF-HL) by dispersing it on a black cotton wick that spans the basin surface. An external condenser (EC) was added to further enhance condensation in a subsequent configuration. Three identical HSS systems were used for comparative performance evaluation: a baseline unit (CHSS) and two modified systems, one with a condenser and one without. The results indicated that both MOF-based approaches significantly improved the thermal performance and freshwater yield of the HSS. Notably, the MOF-HL configuration outperformed the MOF-NF configuration across all performance metrics. The configuration designated as MOF-HL-EC achieved the highest rate of freshwater production, with a 96.16 % increase in distillate productivity compared to the CHSS. Additionally, this configuration exhibited exergy and energy efficiencies of 3.18 % and 61.1 %, respectively—improvements of 80.85 % and 95.72 % over the traditional system. Economically, the MOF-HL-EC configuration reduced the production cost of distilled water to 0.0115$ per liter, marking a reduction of 25.29 %. © 2025 The Institution of Chemical Engineers

Novel blue light-emitting polymers with 9,10-diphenylanthracene as the main backbone were successfully synthesized by Suzuki cross-coupling reaction. The copolymers, pDPA, pDPVDPA and pCBZDPA exhibit good solubility in common organic solvents and show bright blue electroluminescence with maximum emission wavelength of 457 nm, 463 nm and 468nm for pDPA, pDPVDPA and pCBZDPA, respectively. And PLEDs devices showed peak luminous efficiency of 0.55cd/A, 1.28 cd/A and 1.52 cd/A for pDPA, pDPVDPA and pCBZDPA, respectively.

Unified gas-kinetic scheme for multi-species non-equilibrium flow

引用

AIP Conference Proceedings 2014年第1期1628卷 970-975页

作者： Ruijie Wang Kun Xu Nano Science and Technology Program Hong Kong University of Science and Technology Clear Water Bay Kowloon Hong Kong China Department of Mathematics Hong Kong University of Science and Technology Clear Water Bay Kowloon Hong Kong China

The unified gas-kinetic scheme (UGKS) based on the BGK-type gas-mixture model proposed by Andries, Aoki and Perthame is extended to multi-species flow computation. The scheme is validated through the simulations of both shock structure and micro channel flows. In the shock problem, flow variables for individual species are obtained at different Mach numbers. In the micro channel problem, the gas flow due to small pressure difference along a long channel is studied under various Knudsen numbers. Comparison of the UGKS results with the references solutions shows good agreement under moderate Mach number and mass ratio.

Physical and toxicological profiles of human IAPP amyloids and plaques

Although much has been learned about the fibrillization kinetics, structure and toxicity of amyloid proteins, the properties of amyloid fibrils beyond the saturation phase are often perceived as chemically and biologically inert, despite evidence suggesting otherwise. To fill this knowledge gap, we examined the physical and biological characteristics of human islet amyloid polypeptide(IAPP) fibrils that were aged up to two months. Not only did aging decrease the toxicity of IAPP fibrils, but the fibrils also sequestered fresh IAPP and suppressed their toxicity in an embryonic zebrafish model. The mechanical properties of IAPP fibrils in different aging stages were probed by atomic force microscopy and sonication, which displayed comparable stiffness but age-dependent fragmentation, followed by self-assembly of such fragments into the largest lamellar amyloid structures reported to date. The dynamic structural and toxicity profiles of amyloid fibrils and plaques suggest that they play active, long-term roles in cell degeneration and may be a therapeutic target for amyloid diseases.

Electrically tunable helicity of cholesteric heliconical superstructure [Invited]

Chinese Optics Letters 2020年第8期18卷 22-27页

The dynamic manipulation of the helicity in a cholesteric helical superstructure could enable precise control over its physical and chemical properties, thus opening numerous possibilities for exploring multifunctional *** cholesteric material satisfies the sufficiently small bending elastic effect, an electrically induced deformation named the cholesteric heliconical superstructure is formed. Through theoretical and numerical analysis, we systematically studied the tunable helicity of the heliconical superstructure, including the evolution of the corresponding oblique angle and pitch length. To further confirm the optical properties, Berreman’s 4 × 4 matrix method was employed to numerically analyze the corresponding structure reflection under the dual stimuli of chirality and electric field.

For room temperature operation and reproducibility of single electron transistors (SETs), we propose a fabrication method of an SET with a self-aligned quantum dot. The quantum dot is formed by selective etch of a silicon nanowire on a planarized surface and subsequent deposition and etch-back of poly-silicon. The device is named as PQD-SET, i.e., poly-silicon quantum dot SET. PQD-SET shows clear Coulomb oscillation at room temperature.

A normally off-mode AlGaN/GaN heterostructure field effect transistor (HFET) using a p-type GaN gate was fabricated and their static properties were compared with those of HFET having a Schottky gate. HFET having a p-GaN gate contact shows a very low leakage current density of 18.2 μA/mm at VGS and VDS of 0 V and 20 V, respectively.

We investigate the plasmonic responses of gold nanoparticles (AuNP) coated and uncoated on 40nm gold thin film with surrounding medium having different refractive indices using Surface Plasmon Resonance (SPR) ellipsometry. The bulk sensitivities obtained from the measurements in both the cases are found to have same order of magnitude. However SPR dip in case of AuNP coated gold thin film has been shifted to longer wavelength (near IR) as compare to the bare gold thin film under the same environment and condition. Hence, it could provide a good platform to study biomolecular interaction where the absorption of light by the biomolucules is minimal. By monitor the induced changes in polarization state or phase of reflected light from the sample surface, which depend on surface properties of the sample, we use these changes as a sensor signal and compare that with theoretical simulation. This kind of characterization technique is non-destructive, label free and it has high sensitivity and sub-nanometer thickness resolution.
