Hollow nanomaterials, which emerged from nanotechnology, earned a lot of interest due to their unique morphology and extensive surface area. This technology has been widely utilized in water treatment branches such as photocatalysis, membrane technology, and the sorption process. There are several types of hollow nanomaterials, all of which have the potential to treat contaminated water, including pollutants, namel Read More

Nanomaterials are defined as materials with at least one dimension in the range of 1 to 100 nanometers and offer new exceptional properties for membrane development. These include nanosized adsorbents, nanomembranes, nanocomposites, photocatalysts, nanotubes, nanoclays, etc. Nanomaterials have remarkable capabilities for preventing the worldwide water crisis through their outstanding performance in membr Read More

Background: The present study aims to explore the feasibility of using flocculation combined with filtration for microalgae harvesting, i.e., Chlorella vulgaris. This is important because microalgae have small sizes and its broth is stable, which makes it difficult to be harvested. The aforementioned facts cause the harvesting cost to be relatively high and become the bottleneck of microalgae processes. Objective: The objective of thi Read More

Background: Membrane technology demonstrates a sustainable methodology for water reclamation from oily wastewater but is prone to fouling during longer filtration runs. In this study, fouling- resistant polyvinylidene fluoride (PVDF) mixed matrix membranes (MMMs) containing nanoclays, such as halloysite (HT) and montmorillonite (MMT), were fabricated for the effective treatment of oily wastewater. Methods: The phase i Read More

Oral vaccines have been proposed as a potential vaccine against a variety of infections, particularly invading pathogens throughout the GIT. Oral vaccinations targeting the large intestine could be a viable alternative to intracorneal immunizations, which have been shown to be effective against rectogenital infections but are impractical during mass vaccination. Furthermore, the oral route allows the development of hum Read More

Background: The Si- and GaAs-based devices are not suitable for very high-speed and high-power applications. Therefore, GaN-based devices have emerged as a potential contender. Further improvement in the device characteristics using appropriate mole fractions of Al and InN in the barrier layer of AlInN has become inevitable. Objective: To design AlInN/GaN HEMT and present its salient features. Methods: The design metho Read More

Background: Tin monoxide (SnO) attracts considerable interest for p-channel Cylindrical Thin Film Transistors (CTFTs) applications due to their merits, including low hole effective mass, Sn s and O p orbital hybridization at the valance band maxima, and ambipolar nature, among other p-type oxide semiconductors. Objective: This article analyses the influence of channel radius and the impact of dielectric materials on the Read More
