Eco-friendly highly efficient BN/rGO/TiO nanocomposite visible-light photocatalyst for phenol mineralization.

Boron nitride (BN) and reduced graphene oxide (rGO) of different loadings were composited with commercial P25 TiO (Ti) through the hydrothermal method. The as-prepared nanocomposites were characterized using various techniques: X-ray photoelectron spectroscopy, X-ray diffraction, thermal gravimetric analysis, Fourier transform infrared and Raman spectroscopies, and transmission and scanning electron microscopies. It was observed that 10% and 0.

Rational Synthesis of Porous Graphitic-like Carbon Nitride Nanotubes Codoped with Au and Pd as an Efficient Catalyst for Carbon Monoxide Oxidation.

The precise fabrication of efficient catalysts for CO oxidation is of particular interest in a wide range of industrial and environmental applications. Herein, a scalable method is presented for the controlled synthesis of graphitic-like porous carbon nitride nanotubes (gCNNTs) codoped with Au and Pd (Au/Pd/gCNNTs) as efficient catalysts for carbon monoxide (CO) conversion. This includes the activation of melamine with nitric acid in the presence of ethylene glycol and metal precursors followed by consecutive polymerization and carbonization.

Angioinvasive lymphomatoid papulosis: another case of a newly described variant.

Lymphomatoid papulosis (LyP) is a chronic recurrent lymphoproliferative disorder characterized clinically by self-regressing cutaneous lesions. Histologically, it is recognized by clusters of CD30 atypical lymphocytes in the background of mixed inflammatory infiltrate. It has been classified as type A, B, C, and D.

Primary cutaneous CD56 positive lymphoma: a diagnostic conundrum in an unusual case of lymphoma.

We present an unusual case of a CD56-positive T-cell lymphoma exhibiting immunophenotypic characteristics of both γδ T-cell lymphoma and extranodal NK/T-cell lymphoma, nasal-type. The patient presented with a 2-month history of rapidly progressive, pruritic and cutaneous nodules on his arms. A biopsy showed a dense pan-dermal infiltrate of markedly atypical CD3-positive lymphocytes, compatible with tumor stage cutaneous T-cell lymphoma.
