A novel photocatalyst, bismuth oxychloride （BiOC1） micro-nano particles with a fine ferrite plate structure, was prepared by a low-cost, simple hydrolytic method. The as-prepared BLOC1 was characterized by scanning electron microscopy （SEM）, thermogravimetric analysis-differential thermal analysis （TGA-DTA）, X-ray diffraction （XRD）, and UV-vis diffuse reflectance spectra （DRS）. The effects of preparation conditions such as sodium dodecyl benzene sulfonate （SDBS） dispersant, HC1 concentration, and heat treatment temperature on BiOC1 performances were investigated. Moreover, its photocatalytic activity was evaluated on the degradation of methylene orange （MO） and was compared with that of TiO2 （P25）. The experimental results confirmed that BiOC1 micro-nano particles prepared with SDBS, the HC1 concentration of 1.5 mol/L, and the heat treatment temperature of 80℃ exhibited the best performance for the photodegradation of MO solution, and they showed good stability and better photocatalytic activity than P25 photocatalyst.

The powders of ilmenite structure NiTiO3 were prepared by a modified Pechini process using tetrabutyl titanate and nickel acetate as raw materials, and using citric acid and ethanol as a chelating agent and a solvent respectively. The powder samples were characterized by thermogravimetric and differential thermal analysis （TG-DTA） and X-ray diffraction （XRD）. The photocatalytic activity of NiTiO3 under the irradiation of ultraviolet rays （UV） light was evaluated by degrading hurnic acid （HA） in water as a probe reaction. The possible photodegra- dation mechanism was studied by the examination of active species .OH, .O2, and holes （h＋） through adding scavengers. The TG-DTA and XRD results indicated that the good crystal structure of ilmenite phase NiTiO3 could be obtained when the Ni-Ti citrate complex was cal- cined at 600℃. The photocatalytic activity experiments indicated that NiTiO3 had favourable photocatalytic activity under the irradiation of UV light, and the photocatalytic degradation rate of HA reached 95.3% after a 2.5 h reaction with the photocatalyst calcined at 600℃ and a photocatalyst dosage of 0.4 g/L. The possible photocatalytic mechanism was deduced that holes （h＋） and .OH radicals are the major reactive active species in the photocatalytic reaction, and dissolved oxygen plays a weak role in the degradation of HA.

Persistent fifth aortic arch (PFAA) is a rare congenital cardiovascular malformation that occurs when the pharyngeal fifth aortic arch does not degenerate during the embryonic period. The first case of PFAA was described in an autopsy specimen in 1969.[1] In 1973, the persistence of a left fifth aortic arch was first reported.[2] Since then, several case reports have described PFAA in different forms. PFAA stenosis associated with type A interruption of the aortic arch (type-A IAA) is most common in clinical practice and requires surgical intervention. From 2013 to 2018, six cases [Table 1 and Table 2] were diagnosed using echocardiography and computed tomography angiography (CTA). Five cases were successfully treated with surgery and followed-up. The purpose of this study was to summarize the clinical characteristics and diagnostic features of PFAA stenosis associated with type-A IAA to improve its diagnostic accuracy and allow for complete pre-operative preparation and proper treatment.

Selective modification of peptides has always been a challenging issue. The selective alkylation of peptides can alter the biological activity and physical properties of molecules, and it has gained significant research interest. We herein disclose an intriguing gold-catalyzed alkylation of peptides using bench-stable unactivated alkyl bromides under photoredox catalysis. A wide range of structurally diverse primary, secondary and tertiary alkyl bromides serve as effective coupling partners to precisely connect with the α-C(sp3)–H in glycine residue of peptides. This protocol demonstrates an exceptionally broad scope for alkyl halides and excellent tolerance for a wide range of useful functional groups. A series of relay transformations to construct cyclic peptides, to proceed click reaction and to realize peptide fluorescence labeling further enhance its synthetic practicality. In addition, mechanistic studies and density functional theory(DFT) calculations reveal an inner-sphere and subsequent outersphere single electron transfer(SET) mechanism.
