Integrating Cellulose Microfibrils and Ellagitannins from Rambutan Peel with Gelatin for Production of Synergistic Biobased Hydrogels.

The pursuit of renewable and eco-friendly raw materials for biobased materials is a growing field. This study utilized ellagitannin and cellulose microfibrils derived from rambutan peel waste alongside gelatin to develop eco-conscious hydrogels. The cellulose/gelatin hydrogels were formulated in two weight ratios (0.

Probing capping mechanisms and polymer matrix loading of biogenic vaterite CaCO-Ag hybrid through X-ray photoelectron spectroscopy (XPS).

Despite extensive research in the literature, the synthesis of silver nanoparticles (AgNPs) capping mechanisms remains incompletely understood. This study employs a mechanistic approach to unravel the underlying molecular interactions driving the capping process of biogenic vaterite CaCO-Ag and explores their interactions with different polymer matrices. X-ray photoelectron spectroscopy (XPS) was used to reveal the capping mechanisms, surface composition alterations, and vaterite polymorph transitions.

Pioneering dielectric materials of Sn-doped NbTiO ceramics with excellent temperature and humidity stability for advanced ceramic capacitors.

In this study, the rutile TiO system, widely acclaimed for its superior properties, was enhanced through co-doping with isovalent Sn ions and 2.5% Nb donor ions, diverging from traditional acceptor doping practices. This novel doping strategy was implemented by employing a conventional solid-state reaction method, resulting in the synthesis of Sn-doped NbTiO (Sn-NTO) ceramics.

Fabrication and Characterization of a Polydopamine-Modified Bacterial Cellulose and Sugarcane Filter Cake-Derived Hydroxyapatite Composite Scaffold.

The search for environmentally friendly and sustainable sources of raw materials has been ongoing for quite a while, and currently, the utilization and applications of agro-industrial biomass residues in biomedicine are being researched. In this study, a polydopamine (PDA)-modified bacterial cellulose (BC) and hydroxyapatite (HA) composite scaffold was fabricated using the freeze-drying method. The as-prepared hydroxyapatite was synthesized via the chemical precipitation method using sugarcane filter cake as a calcium source, as reported in a previous study.

Enhancement of VO Li-ion cathode stability by Ni/Co doped Li-borate-based glass.

In this research, we investigate the stability of a Li-ion cathode created by mixing a borate based glass which has been doped with Ni/Co and vanadium pentoxide (VO). VO has a high specific capacity in battery systems because of its layered structure and variety of oxidation states. However, due to the flimsy structure, the capacity stability of VO is fairly low.

Formation and growth characteristics of nanostructured carbon films on nascent Ag clusters during room-temperature electrochemical CO reduction.

Synthesis of carbon nanostructures at room temperature and under atmospheric pressure is challenging but it can provide significant impact on the development of many future advanced technologies. Here, the formation and growth characteristics of nanostructured carbon films on nascent Ag clusters during room-temperature electrochemical CO reduction reactions (CORR) are demonstrated. Under a ternary electrolyte system containing [BMIm][BF], propylene carbonate, and water, a mixture of sp/sp carbon allotropes were grown on the facets of Ag nanocrystals as building blocks.

Correlating the effect of preparation methods on the structural and magnetic properties, and reducibility of CuFeO catalysts.

CuFeO spinel oxide has attracted research interest because of its versatile practical applications, especially for catalysis. In this study, nanometre-sized CuFeO particles were prepared by three different methods, including nanospace confinement in SBA-15, hard template removal, and sol-gel combustion. The relationship between structure, size, magnetic behaviour, and reducibility of the catalysts was further investigated by various advanced techniques.

Fe/Nb Co-doped rutile-TiO nanocrystalline powders prepared by a combustion process: preparation and characterization and their giant dielectric response.

Fe/Nb co-doped TiO (FeNb-TO) nanocrystalline powders were prepared by a combustion process. A pure rutile-TiO phase of powders and sintered ceramics with a dense microstructure was achieved. Both co-dopants were homogeneously dispersed in the ceramic microstructure.

Significant enhancement of dielectric permittivity and percolation behaviour of La Sr NiO/poly(vinylidene fluoride) composites with different Sr doping concentrations.

The percolation behaviour and dielectric properties of La Sr NiO (LSNO)/poly(vinylidene fluoride) (PVDF) composites with different Sr doping concentrations were investigated. The semiconducting LSNO filler particles with = 0.2 (LSNO-1) and = 0.

Nanoceria-modified platinum supported on hierarchical zeolites for selective alcohol oxidation.

The highly selective oxidation of alcohols to aldehydes has been achieved due to the synergic effect of Pt and CeO supported on hierarchical zeolites. The combination of Pt and CeO strongly enhances the catalytic performance of the oxidation of benzyl alcohol to benzaldehyde with respect to the isolated materials. In addition, the hierarchical zeolite not only increases the fraction of exposed active sites because of its high surface area that can prevent the aggregation of Pt and CeO nanoparticles, but also affects the oxidation state of cerium.
