In situ shaping of intricated 3D bacterial cellulose constructs using sacrificial agarose and diverted oxygen inflow.

Bacterial cellulose (BC) is gathering increased attention due to its remarkable physico-chemical features. The high biocompatibility, hydrophilicity, and mechanical and thermal stability endorse BC as a suitable candidate for biomedical applications. Nonetheless, exploiting BC for tissue regeneration demands three-dimensional, intricately shaped implants, a highly ambitious endeavor.

Adsorption of cationic dye onto Raphanus seeds: optimization, adsorption kinetics, thermodynamic studies.

Dyes are one of the common contaminants in industrial wastewater. Adsorption is the most widely method which used to treat dye-contaminated water due to their easy use, cost-effectiveness, and their efficiency was high. The aim of this study is the investigating of the utilization of the activated carbon which prepared from Raphanus seeds solid residual (ACRS) as a low cost adsorbent for removing of cationic Methylene Blue dye (MB)from wastewater.

Formulation of silver phosphate/graphene/silica nanocomposite for enhancing the photocatalytic degradation of trypan blue dye in aqueous solution.

Photocatalytic degradation of several harmful organic compounds has been presented as a potential approach to detoxify water in recent decades. Trypan Blue (TB) is an acidic azo dye used to distinguish live cells from dead ones and it's classified as a carcinogenic dye. In this study, silver phosphate (AgPO) nanoparticles and novel AgPO/graphene/SiO nanocomposite have been successfully prepared via simple precipitation method.

Antibiotic-free combinational hyaluronic acid blend nanofibers for wound healing enhancement.

An innovative approach in the functionalization of nanofibers (NFs) for wound healing relies on non-antibiotic combinational therapy to subdue microbial invasion while reducing antimicrobial resistance and enhancing healing. Despite great potentials, wound healing efficacy of NFs embedding antimicrobial metal nanoparticles (NPs)/essential oils has been scarcely documented. We developed combinational NFs using an electrospinnable hyaluronic acid/polyvinyl alcohol/polyethylene oxide blend embedding a new ZnO NPs/cinnamon essential oil (CEO) antimicrobial combination.

Production of Thermoalkaliphilic Lipase from Geobacillus thermoleovorans DA2 and Application in Leather Industry.

Thermophilic and alkaliphilic lipases are meeting a growing global attention as their increased importance in several industrial fields. Over 23 bacterial strains, novel strain with high lipolytic activity was isolated from Southern Sinai, Egypt, and it was identified as Geobacillus thermoleovorans DA2 using 16S rRNA as well as morphological and biochemical features. The lipase was produced in presence of fatty restaurant wastes as an inducing substrate.
