Ferromagnetic two-dimensional (2D) ultrathin nanosheets hold great promise for next generation electronics. Ferromagnetic metal-free materials that usually possess only an s/p electronic configuration with weak spin–orbit coupling and a large spin relaxation time, would play an important role in constructing future spintronic devices. However, the absence of an intrinsic spin ordering structure...

In this study, ZnO/g-C3N4 nanocomposites were prepared via a physical mixing-calcination process for improved degradation of dyes under visible light irradiation. The BET surface area, pore volume, crystal size, and pHpzc the composite 3.9 m2/g, 0.034 cm3/g, 18.1 nm, 7.7, respectively. Although morphology was very different from that pure g-C3N4, their average sizes similar. Eg (3.195 eV) sligh...

The development of high catalytic performance heterogeneous catalysts such as peroxymonosulfate (PMS) activators is important for the practical remediation organic pollution caused by Rhodamine B (RhB). An economical and facile synthesized composite copper–magnesium oxide carbon nitride (CM/g-C3N4) was prepared sol-gel/high-temperature pyrolysis method to activate PMS RhB degradation. CM/g-C3N4...

BACKGROUND The aim of this study was to evaluate the interaction of bioactive and biodegradable poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (PBGHA) and poly (lactide-co-glycolide)/bioactive glass (PBG) nanocomposite coatings with bone. MATERIALS AND METHODS Sol-gel derived 58S bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite na...

Cellulous-fiber papers are used as 3D structural templates for the assembly of graphene and graphitic carbon nitrate (g-C3N4) ultrathin nanosheets. The resultant materials, which possess highly active centers, rich porosity, and 3D conductive networks, can catalyze the oxygen evolution reaction with competitive activity and much better durability compared to the benchmark noble metal electrocat...

A high rate of 2.23 mmol h(-1) g(-1) (quantum efficiency of 6.67% at 400 nm) for visible light driven photocatalytic H2 evolution can be achieved with g-C3N4 by alkalization of the solution to a pH of 13.3, due to accelerated transfer of photoholes to the sacrificial donor.

A synthetic route to low-density porous Ni-doped Co3O4 nanomaterials that show stable and superior electrocatalytic activity for O2 evolution reaction is reported. The materials are prepared via thermal treatment of "pre-synthesized" metal ions-embedded graphitic C3N4-based polymers.

Chitosan–silver (CS–Ag) nanocomposite materials were synthesized by a simple chemical method. The synthesized CS–Ag nanocomposite contains 20 wt% silver. Silver nanoparticles were synthesized by chemical reduction method as well. The CS–Ag nanocomposite was characterized using Field emission scanning electronic microscope (FESEM), X-ray diffraction (XRD) and Fourier transform infrared spectrosc...
