Novel sub-microsized graphitic carbon shells embedding nanometric Gd(III) oxidic phases feature thermal and chemical inertness with enhanced T2 relaxation in aqueous dispersions, thus representing potential candidates for dual diagnostic (magnetic resonance imaging) and therapeutic (neutron capture therapy) applications.

We determined the carbon structures in condensed soot samples of variable C/H ratio by using both scanning and transmission electronmicroscopy.We identified several types of carbon structures. All the samples are formedmainly by “chainlike aggregates” of amorphous grains. A small amount of more ordered forms of carbon is also detected. A “poorly graphitized carbon” is formed on a pre-existing a...

A facile, two-step method for chemically attaching single-stranded DNA to graphitic surfaces, represented here by carbon nanotubes, is reported. In the first step, an azide-containing compound, N-5-azido-nitrobenzoyloxy succinimide (ANB-NOS), is used to form photo-adducts on the graphitic surfaces in a solid-state photochemical reaction, resulting in active ester groups being oriented for the s...

Ordered mesoporous carbons with various structures, designated as CMK-1~5, have been synthesized by carbonization of sucrose, furfuryl alcohol or other suitable carbon sources inside silica or aluminosilicate mesopores that are interconnected into three-dimensional networks such as in MCM-48 (cubic Ia3d), SBA-1 (cubic Pm3n) and SBA-15 (hexagonal p6mm). The mesoporous carbon molecular sieves, ob...

A process aimed at the recovery of terbium from liquid solutions using activated carbon (AC) derived spent coffee grounds (SCG) was assessed. AC obtained hydro-alcoholic treatment SCG, followed by physical activation as-obtained product. The exhibited both microporous and mesoporous structures, which were shown corresponding nitrogen adsorption–desorption isotherms scanning electron microscopy ...

A mesoporous Zr-G-C3N4 nanomaterial was synthesized by a succinct-step ultrasonication technique and used for Cu2+ ion uptake in the aqueous phase. The adsorption of examined varying operating parameters, including initial metal concentration, contact time, pH value. nanosorbent displays graphitic carbon nitride (g-C3N4) ZrO2 peaks with crystalline size ~14 nm, as determined XRD analysis. sorbe...

Polycyclic aromatics hydrocarbons are chemical species with two to six fused benzene rings and are well-known toxic hazardous pollutants and highly potent carcinogens that can cause tumors in some organisms.1 In recent years, naphthalene contamination in water systems has drawn increasing attention. Naphthalene originates from natural and anthropogenic sources. Anthropogenic sources include eng...
