Delivery systems based on filled hydrogel particles (microgels) can be fabricated from natural food-grade lipids and biopolymers. The potential for controlling release characteristics by modulating the electrostatic interactions between emulsifier-coated lipid droplets and the biopolymer matrix within hydrogel particles was investigated. A multistage procedure was used to fabricate calcium algi...

Detection and quantification of pathogens in water is critical for the protection of human health and for drinking water safety and security. When the pathogen concentrations are low, large sample volumes (several liters) are needed to achieve reliable quantitative results. However, most microbial identification methods utilize relatively small sample volumes. As a consequence, a concentration ...

In this study chitosan hydrogel beads with porosity ~ 0.86 and diameter ~ 20.07 mm were prepared from 85 % deacetylated chitosan for removal of Cd2+ ions from aqueous solutions.  Chitosan powder was dissolved into dilute acetic acid as solvent and formed into spherical beads using a phase inversion technique. The effect of temperature, initial ...

Groundwater is the source of all tap water in Kumamoto City, Japan. However, concentration nitrate nitrogen (NO3−-N) tends to increase every year due influences overfertilization, field disposal livestock manure, and inflow domestic wastewater. A heterotrophic nitrification–aerobic denitrification (HN-AD) system an attractive approach for nitrate-nitrogen removal. In this study, Rhodotorula gra...

Tumor metastasis with resistance to anticancer therapies is the main cause of death in cancer patients. It is necessary to develop reliable tumor metastasis models that can closely recapitulate the pathophysiological features of the native tumor tissue. In this study, chondroitin sulfate (CS)-modified alginate hydrogel beads (ALG-CS) are developed to mimic the in vivo tumor microenvironment wit...

Appropriately disposing of and reusing waste is a major step in promoting environmentally sustainable development. Following the rise environmental awareness, agricultural has been applied as reusable organic resource cost-efficient material for preparing hydrogel adsorbents. The present study combined rice bran with sodium alginate chitosan to prepare two new types beads. beads were then modif...

Abstract Optical Coherence Tomography (OCT) is a standard imaging procedure in ophthalmology. OCT Angiography promising extension, allowing for fast and non-invasive of the retinal vasculature analyzing multiple scans at same place. Local variance examined highlighted. Despite its introduction clinic, unanswered questions remain when it comes to signal generation. Multiphase fluids like intrali...
