Facile Synthesis of Ag Nanowire/TiO and Ag Nanowire/TiO/GO Nanocomposites for Photocatalytic Degradation of Rhodamine B.

This paper investigates the photocatalytic characteristics of Ag nanowire (AgNW)/TiO and AgNW/TiO/graphene oxide (GO) nanocomposites. Samples were synthesized by the direct coating of TiO particles on the surface of silver nanowires. As-prepared AgNW/TiO and AgNW/TiO/GO nanocomposites were characterized by electron microscopy, X-ray diffraction, UV/visible absorption spectroscopy, and infrared spectroscopy.

The inactivation mechanism of chemical disinfection against SARS-CoV-2: from MD and DFT perspectives.

Exploring effective disinfection methods and understanding their mechanisms on the new coronavirus is becoming more active due to the outbreak of novel coronavirus pneumonia (COVID-19) caused by severe acute respiratory coronavirus 2 (SARS-CoV-2). By combining molecular dynamics and first-principles calculations, we investigate the interaction mechanism of chemical agents with 3CL hydrolase of SARS-CoV-2. The radial distribution functions indicate that the biocidal ingredients are sensitive to the unsaturated oxygen atoms of 3CL hydrolase and their interactions remarkably depend on the concentration of the biocidal ingredients.

Towards Multi-Functional SiO@YAG:Ce Core-Shell Optical Nanoparticles for Solid State Lighting Applications.

This paper aims to investigate the synthesis, structure, and optical properties of SiO@YAG:Ce core-shell optical nanoparticles for solid state lighting applications. YAG:Ce phosphor is a key part in white light emitting diodes (LEDs), with its main functionality being the generation of yellow light. Generated yellow light from phosphor will be combined with blue light, emitted from chip, resulting in the generation of white light.

High-resolution MEMS inertial sensor combining large-displacement buckling behaviour with integrated capacitive readout.

Commercially available gravimeters and seismometers can be used for measuring Earth's acceleration at resolution levels in the order of (where g represents earth's gravity) but they are typically high-cost and bulky. In this work the design of a bulk micromachined MEMS device exploiting non-linear buckling behaviour is described, aiming for resolution by maximising mechanical and capacitive sensitivity. High mechanical sensitivity is obtained through low structural stiffness.

Study on the Degradation of Optical Silicone Exposed to Harsh Environments.

Degradation mechanisms of silicone plates under harsh environment conditions are studied in this investigation. Environmental degradation of silicone free form, used as secondary optics in Light Emitting Diode LED lighting lamps and luminaires or any other applications requiring high quality optics being used, has negative implications for the optical performance. Degradation of silicone plates in harsh environment conditions was studied in salt bath and swimming water environments, using different light radiation and temperatures.

Automatic diagnosis and control of distributed solid state lighting systems.

This paper describes a new design concept of automatically diagnosing and compensating LED degradations in distributed solid state lighting (SSL) systems. A failed LED may significantly reduce the overall illumination level, and destroy the uniform illumination distribution achieved by a nominal system. To our knowledge, an automatic scheme to compensate LED degradations has not yet been seen in the literature, which requires a diagnostic step followed by control reconfigurations.

Challenges in the assembly and handling of thin film capped MEMS devices.

This paper discusses the assembly challenges considering the design and manufacturability of a Wafer Level Thin Film Package in MEMS applications. The assembly processes are discussed. The loads associated with these processes are illustrated and evaluated.
