Addition of TiO2 to a polytetrafluoroethylene (PTFE) particle-dispersed composite contributes to the self-cleaning properties of the water-repellent composite. However, its application is limited to outdoor usage or under ultraviolet (UV) irradiation. In this study, a novel visible-light-sensitive photocatalytic and superhydrophobic material was developed by adding Cu/WO3 to a PTFE particulate ...

Hyperspectral microscopy is rapidly developing as an effective tool for characterizing existing FDA approved APIs (active pharmaceutical ingredients) that are being incorporated with nano or micron-scale vectors for targeted drug delivery. It is also utilized extensively to image and characterize nanomaterials used in photothermal therapy and related theranostic studies as well as nanotoxicolog...

Thin film of tungsten oxide (WO3) has been studied extensively as an electrochromic material and has numerous applications in electrochromic devices, smart windows, gas sensors and optical windows. In order to explore the possibility of using it in electrochromic devices, thorough study the optical properties of the WO3 is an important step. The WO3 layers have been grown by hot-filament metal ...

Entrapment of sub-micron scale emulsions containing active ingredients into macro-scale matrices has exhibited great potential as a delivery vehicle with controlled release capabilities, however optimization remains unrealized. Reported here are methods used to improve product quality by optimizing the emulsion formation steps. These methods are in conjunction with the precepts of Process Inten...

In this work, a facile method was adopted to prepare TiO2-WO3 loaded onto wood surface by two-step hydrothermal method. The as-prepared composite material can be used as photocatalyst under UV irradiation for the photodegradation of formaldehyde. Related tests showed that nano-architectonic materials with spherical particles substratewere mainly caused self-photodegradation nanostructured firml...

Chemically patterned surfaces are of significant interest in the context of microfluidic applications. Miniaturization of such devices will eventually lead to structures on the nano-scale. Whereas on the micron scale purely macroscopic descriptions of liquid flow are valid, on the nanometer scale long-ranged inter-molecular interactions, thermal fluctuations such as capillary waves, and finally...

Microsized particles play an important role in many diverse areas of science and technology, for example, surface reactions of micron-sized particles play a key role in astrochemistry, plasma reactors and atmospheric chemistry. To date much of our knowledge of such surface chemistry is derived from 'traditional' surface science-based research. However, the large surface area and morphology of s...
