Porous nanocomposite hydrogels were prepared using CaCO<sub>3</sub> particles as solid porogens.
Gold nanomaterials have received great interest for their use in cancer theranostic applications over the past two decades. Many gold nanoparticle-based drug delivery system designs rely on adsorbed ligands such as DNA or cleavable linkers to load therapeutic cargo. The heightened research was recently demonstrated simple design of nanoparticle-drug conjugates wherein molecules are directly onto as-synthesized nanoparticle surface. potent chemotherapeutic, doxorubicin often serves a model...
We synthesized magnetic mesoporous carbon (Ni-CMK-3) as an adsorbent for removal of sulfur from model oil (dibenzothiophene, DBT, in n-hexane). X-ray diffraction and transmission electron microscopy analyses revealed the presence face-centered cubic Ni nanoparticles with average size 17 ± 3 nm, indicated that support retained its mesoporosity morphology after immobilization metal nanoparticles. Nitrogen adsorption measurements resultant Ni-CMK-3 possesses high surface area (705 m2 g− 1),...
Single crystal (SC) cathode materials with a layered structure are considered to be state-of-the-art for lithium ion batteries. However, their production involves many steps and can produce large amounts of wastewater. Here we report an all-dry method making SC materials, LiNi 0.6 Mn 0.2 Co O 2 (SC-NMC) used as specific example. It was found that SC-NMC precursor in the form previously unobserved rock-salt (Ni, Mn, Co)O solid solution phase made pure by ball milling. This demonstrates...
A novel magnetically recoverable oxidation catalyst was prepared in which magnetic nanoparticles were entrapped a tungstate functionalized poly(ionic liquid) matrix. Using H2O2 as an oxidant, wide range of substrates including alcohols, sulfides and olefins selectively oxidized with excellent yields. The resulting characterized by FTIR, TGA, SEM, TEM, XRD, XRF, CHN, vibrating sample magnetometer (VSM) atomic adsorption spectroscopy (AAS). can be readily recovered reused at least ten times...

Layered cathode materials based on abundant, low cost raw have garnered interest in recent years. O3-type NaCrO2 is a promising material as it offers decent energy density and easy to synthesize. In this study, calcium doped was synthesized using solid-state method the resulting [Na1-2xCax]CrO2 were studied sodium cells. Compared calcium-free NaCrO2, [Na0.9Ca0.05]CrO2 has improved capacity retention without sacrificing reversible capacity. The enhanced performance ascribed structural...
The transformation of crystalline silicon to amorphous during ball milling was quantitatively measured by x-ray diffraction and electrochemical methods. Amorphous found form rapidly from the very initial stages milling. Simultaneously, grain size phase decreased. Under extended times it that a maximum 86 % became amorphous. Similarly, could not be reduced below 6 nm. This followed an Avrami kinetic model, which is consistent with system reaches steady state. These observations suggest...
We present the results of our 15th horizon scan novel issues that could influence biological conservation in future. From an initial list 96 issues, international panel scientists and practitioners identified 15 we consider important for societies worldwide to track potentially respond to. Issues are within or represent a substantial positive negative step-change with global regional extents. For example, new sources hydrogen fuel changes deep-sea currents may have profound impacts on marine...

Lamellar, or layered, potassium niobium oxide perovskites are a class of underdeveloped semiconductors in organic photocatalysis that offer the inherent advantages larger particle size and ease recoverability as compared to traditional semiconductor materials.
Allergen-specific immunotherapy represents the only method of achieving a lasting reduction in severity allergic symptoms. However, need to expose patients allergens which they are sensitized carries risks. One solution is use denatured whereby structure allergenic proteins disrupted, preventing their recognition by immunoglobulin E (IgE) antibodies and thus reducing risk adverse reactions. Denaturation often carried out using chemical cross-linking generate allergoids. Gold nanoclusters...

Abstract A highly crystalline graphite powder was prepared from the low temperature (800–1000 °C) graphitization of renewable hard carbon precursors using a magnesium catalyst. The resulting particles are composed Voronoi‐tessellated regions comprising irregular sheets; each region having small “seed” particle located near their centroid on surface. This suggests nucleated outward growth graphitic carbon, which has not been previously observed. Each seed consists spheroidal shell inside...
Layered double hydroxide nanoparticles (LDH NPs) have attracted interest as an effective gene delivery vehicle in biomedicine. Recent advances clinic trials demonstrated the efficacy of Mg/Fe LDHs for hyperphosphatemia treatment, but their feasibility has not been systematically evaluated. As a starting point, we aimed to study interaction between oligo-DNA and LDH NPs. Our investigation revealed chemisorption mechanism DNA on surfaces, wherein phosphate backbone polymer coordinates with...
