The present research was aimed at the enhancement of the dissolution rate of atorvastatin calcium by the solid dispersion technique using modified locust bean gum. Solid dispersions (SD) using modified locust bean gum were prepared by the modified solvent evaporation method. Other mixtures were also prepared by physical mixing, co-grinding, and the kneading method. The locust bean gum was subje...

Harvesting micro-droplets from fog is a promising method for solving global freshwater crisis. Different types of fog collectors have been extensively reported during the last decade. The improvement of fog collection can be attributed to the immediate transportation of harvested water, the effective regeneration of the fog gathering surface, etc. Through learning from the nature's strategy for...

The lithium-sputtering yield from lithium and tin-lithium surfaces in the liquid state under low-energy, singly charged particles as a function of target temperature is measured by using the IIAX (Ion-surface Interaction Experiment) facility. Total erosion exceeds that expected from conventional physical sputtering after accounting for lithium evaporation for temperatures between 200 and 400 oC...

In this study, idealized simulations of squall line traversing a bell-shape mountain in a three-dimensional framework are conducted using the Weather Research and Forecasting (WRF) model, version 3.2.0, with 2-km horizontal grid size and 60 vertically stretched layers. Water vapor and condensate budgets are examined, and the temporal variations of four microphysics ratios, including precipitati...

Surface enhanced Raman scattering (SERS) is an analytical sensing method that provides label-free detection, molecularly specific information, and extremely high sensitivity. The Raman enhancement that makes this method attractive is mainly attributed to the local amplification of the incident electromagnetic field that occurs when a surface plasmon mode is excited at a metallic nanostructure. ...

The combustion of a moving liquid fuel drop has been investigated. The drop experiences a strong evaporation-induced radial velocity while undergoing slow translation. In view of the high evaporation velocity, the flow field is not in the Stokes regime. The combustion process is modelled by an indefinitely fast chemical reaction rate. While the flow and the transport in the continuous phase and...
