Enhanced ultraviolet-visible photocatalysis of RGO/equaixial geometry TiO composites on degradation of organic dyes in water.

The reduced graphene oxide dopped equaixial geometry TiO (rGO/egTiO) composite as photocatalyst was synthesized hydrothermally with various mass ratios of tetrabutyl titanate. The photocatalyst is considered to be rGO/equaixial geometry TiO in terms of modifying the combined reduced graphene Oxide and TiO. The rGO plays a vital role in rGO/egTiO composite as photocatalysts were analyzed in methylene blue (MB) and rhodamine B (RhB) photocatalytic degradation under UV and simulated solar light irradiation.

Synthesis of Tri(4-formylphenyl) Phosphonate Derivatives as Recyclable Triple-Equivalent Supports of Peptide Synthesis.

To seek the novel application of organophosphorus compounds, the designed tri(4-formylphenyl) phosphonate (TFP) derivatives were successfully synthesized herein, which were used as C-terminal protecting groups of amino acid or greener triple-equivalent supports in liquid-phase peptide synthesis (LPPS). Through the support-aided precipitation effect of TFP derivatives, the peptide intermediates during peptide synthesis were separated and collected via rapid precipitation and facile filtration without chromatographic purification. Furthermore, the TFP derivative support can be directly recycled for reuse without further regeneration after being sheared from the target peptide.

Patterns of epidermal growth factor receptor mutation in non-small-cell lung cancers in the Gulf region.

The aim of the present study was to determine the prevalence of epidermal growth factor receptor mutations (EGFRmut) in the Gulf region (GR) and its correlation with demographic and clinical characteristics. A multisite retrospective study was conducted, including institutions from Saudi Arabia, the United Arab Emirates and Qatar. All consecutive patients with non-small-cell lung cancer tested for EGFRmut were eligible.
