Biomass as an alternative feedstock to oleochemicals.

The huge demands for petrochemicals have led to a rapid increase in the production of these fossil-based derivatives. Biomass represents a promising feedstock for addressing the challenges related to petrochemicals in terms of the necessity to apply renewable sources and the need to decrease carbon emissions. Among the natural biomass products, most studies have attempted to upgrade natural oils owing to their promising advantages of worldwide availability, low-cost processing, and built-in functionality.

Coprecipitation and hydrothermal synthesis of CaO from dolomite in the presence of extract for biodiesel production: catalysts characterization and optimization.

High-purity CaO cubic crystallites extracted from limestone exhibited excellent activity as base catalysts for waste cooking oil (WCO) conversion into biodiesel. Saponin from extract acted as a surfactant in CaO extraction and transformation into well-defined cubic microcrystallites. The application of saponin from extract as a surfactant for CaO production results in a high level of CaO purity and particle size reduction compared to directly calcined limestone (CaO-MgO).

The Biofilm Inhibition Properties of Glucosamine Gold Nanoparticles in Combination with Meropenem against on the Endotracheal Tube: A Model of Biofilm-Related Ventilator-Associated Pneumonia.

Biofilm-related infections play a significant role in the development and persistence of ventilator-associated pneumonia. () frequently causes biofilm-related infections associated with ventilator tubing. Glucosamine gold nanoparticles (AuNPs) may exhibit antibiofilm properties; however, more studies, including combinatorial therapy with antibiotics, are needed to explore their potential applications in clinical settings.

A Composite of Hydrogel Alginate/PVA/r-GO for Scaffold Applications with Enhanced Degradation and Biocompatibility Properties.

We reported in this study the interrelation between the addition of 0.4, 0.8, 1.

The application of silica gel synthesized from chemical bottle waste for zinc (II) adsorption using Response Surface Methodology (RSM).

The application of silica gel adsorbent synthesized from chemical bottle waste to remove zinc ions in the solution has been carried out. The synthesis of silica gel was carried out using alkaline fusion followed by sol-gel reactions. The chemical glass bottle container was made from borosilicate glass which was different from glass bottles for food and beverage that has been studied in previous studies.

The Fabrication of Solid Polymer Electrolyte from CS/PEO/NaClO/Fly Ash Composite.

Solid polymer electrolytes (SPEs) have been successfully fabricated from CS/PEO/NaClO/Fly ash composite. Chitosan (CS), an organic polymer, was blended with polyethylene oxide (PEO) to enhance its electrochemical properties. However, SPEs based on CS/PEO composites have low conductivity.

Increase of Solid Polymer Electrolyte Ionic Conductivity Using Nano-SiO Synthesized from Sugarcane Bagasse as Filler.

The synthesize of solid polymer electrolyte (SPE) based on polyethylene oxide (PEO), NaClO and nano-SiO was carried out by solution cast technique. Nano-SiO was synthesized from sugarcane bagasse using sol-gel method. FTIR analysis was carried out to investigate the bonding between nano-SiO and PEO/NaClO.

Comparison of the effects of synthesis methods of B, N, S, and P-doped carbon dots with high photoluminescence properties on HeLa tumor cells.

Although heteroatom doping is widely used to promote the optical properties of carbon dots for biological applications, the synthesis process still has problems such as multi-step process, complicating the setting of instrument along with uncontrolled products. In the present study, some elements such as boron, nitrogen, sulfur, and phosphor were intentionally doped into citric acid-based carbon dots by furnace- and microwave-assisted direct and simple carbonization processes. The process produced nanoparticles with an average diameter of 5-9 nm with heteroatoms (B, N, S, and P) placed on the core and surface of carbon dots.
