Facile synthesis of SnO2-PbS nanocomposites with controlled structure for applications in photocatalysis.

Nanoscale

Kar A, Sain S, Rossouw D, Knappett BR, Pradhan SK, Wheatley AE.
PMID: 26765053
Nanoscale. 2016 Feb 07;8(5):2727-39. doi: 10.1039/c5nr07036h.

Recent studies have shown that SnO2-based nanocomposites offer excellent electrical, optical, and electrochemical properties. In this article, we present the facile and cost-effective fabrication, characterization and testing of a new SnO2-PbS nanocomposite photocatalyst designed to overcome low photocatalytic efficiency...

Cardiac catheterization is important in the diagnosis and risk stratification of pulmonary hypertensive vascular disease (PHVD) in children. Acute vasoreactivity testing provides key information about management, prognosis, therapeutic strategies, and efficacy. Data obtained at cardiac catheterization continue to play...

Acta Crystallogr A. 2001 May;57:321-32. doi: 10.1107/s0108767300019577. Epub 2001 May 01.

Systematic electron diffraction studies on intermetallic precipitates formed within a lightweight Mg-RE-Zn alloy (RE = La or Ce) identify these to be of structural type Mn(12)Th (space group I4/mmm). Analytical electron microscopy yields an overall composition of Mg(12)(La(x)Ce(1-x)) with...

A Bloch wave theory for incoherent scattering of an incident plane wave has proved successful in predicting the fine detail in 2-D zone axis channelling patterns formed by ADF, BSE and characteristic X-ray detection in beam rocking mode. A...

Estrogen-progestin therapy was not effective in secondary prevention of CHD in post-menopausal women.

SARS-CoV-2 501Y.V2 (B.1.351), a novel lineage of coronavirus causing COVID-19, contains substitutions in two immunodominant domains of the spike protein. Here, we show that pseudovirus expressing 501Y.V2 spike protein completely escapes three classes of therapeutically relevant antibodies. This pseudovirus...
