Muscle Proteins, Technological Properties, and Free Amino Acids of Epaxial Muscle Collected from Asian Seabass () at Different Postmortem Durations.

The aim of this study was to compare the changes in the epaxial muscle proteins of Asian seabass at two different postmortem durations. The epaxial muscles of Asian seabass were collected 1 h or 24 h postmortem (PM). Whole, ungutted fish were stored in an ice box, with the ice refilled every two hours.

Chemical Composition, Sources, and Health Risk Assessment of PM and PM in Urban Sites of Bangkok, Thailand.

Of late, air pollution in Asia has increased, particularly in built-up areas due to rapid industrialization and urbanization. The present study sets out to examine the impact that pollution can have on the health of people living in the inner city of Bangkok, Thailand. Consequently, in 2021, fine particulate matter (PM) and coarse particulate matter (PM) chemical composition and sources are evaluated at three locations in Bangkok.

Structure, dissolution, and plant uptake of ferrous/zinc phosphates.

Development of slow release fertilizers by tuning dissolution kinetics can reduce the environmental impact of (micro) nutrients added to crops. Mixed metal compounds may have different dissolution kinetics and plant uptake than single metal compounds. In this study, mixed Fe(II)/Zn(II) phosphates (0-100 at% Zn) were prepared by aqueous precipitation and their structural characteristics and dissolution kinetics in a sand column were measured as model for divalent metal and phosphate release in soil.

Effect of a pH-controlled co-precipitation process on rhodamine B adsorption of MnFeO nanoparticles.

We investigated the effect of a pH-controlled co-precipitation process on the adsorption behavior of manganese ferrite (MnFeO) nanoparticles as well as their structural and magnetic properties. The pH of prepared MnFeO nanoparticles is typically an important factor affecting the adsorption capacity of an adsorbent. In this study, MnFeO nanoparticles were prepared using a co-precipitation method at four different pH values of 9.

Composite Photocatalysts Containing BiVO for Degradation of Cationic Dyes.

The creation of composite structures is a commonly employed approach towards enhanced photocatalytic performance, with one of the key rationales for doing this being to separate photoexcited charges, affording them longer lifetimes in which to react with adsorbed species. Here we examine three composite photocatalysts using either WO, TiO or CeO with BiVO for the degradation of model dyes Methylene Blue and Rhodamine B. Each of these materials (WO, TiO or CeO) has a different band edge energy offset with respect to BiVO, allowing for a systematic comparison of these different arrangements.

Enhancement of Cr(VI) Ion Removal Using Nanochitosan Coated on Bituminous Activated Carbon.

  Bituminous activated carbon (AC) has been widely used as a sorbent for adsorption of non-polar species, but its performance for removal of ionic species such as heavy metals has not been as efficient. In this study, AC was modified with chitosan nanoparticles (CN) using facile methods of dip coating and wet impregnation. The CN-coated AC demonstrated an increase in Cr(VI) removal efficiency in both kinetics and adsorption capacity.

Determination of silver nanoparticle release from antibacterial fabrics into artificial sweat.

Silver nanoparticles have been used in numerous commercial products, including textiles, to prevent bacterial growth. Meanwhile, there is increasing concern that exposure to these nanoparticles may cause potential adverse effects on humans as well as the environment. This study determined the quantity of silver released from commercially claimed nanosilver and laboratory-prepared silver coated fabrics into various formulations of artificial sweat, each made according to AATCC, ISO and EN standards.

Antibacterial effect of apatite-coated titanium dioxide for textiles applications.

An antibacterial activity of apatite-coated titanium dioxide (TiO2) against four types of bacteria (Staphylococcus aureus, Escherichia coli, methicillin-resistant Staphylococcus aureus (MRSA), and Micrococcus luteus) was investigated. Its antibacterial performance was observed under black light, visible light, and dark conditions. The number of viable bacteria decreased with irradiation time and became most prominent at 24 hours.
