Functionalization of MXene Nanosheets for Polystyrene towards High Thermal Stability and Flame Retardant Properties.

Fabricating high-performance MXene-based polymer nanocomposites is a huge challenge because of the poor dispersion and interfacial interaction of MXene nanosheets in the polymer matrix. To address the issue, MXene nanosheets were successfully exfoliated and subsequently modified by long-chain cationic agents with different chain lengths, i.e.

Novel 3D Network Architectured Hybrid Aerogel Comprising Epoxy, Graphene, and Hydroxylated Boron Nitride Nanosheets.

A novel three-dimensional (3D) epoxy/graphene nanosheet/hydroxylated boron nitride (EP/GNS/BNOH) hybrid aerogel was successfully fabricated in this study. This was uniquely achieved by constructing a well-defined and interconnected 3D network architecture. The manufacturing process of EP/GNS/BNOH involved a simple one-pot hydrothermal strategy, followed by the treatment of freeze-drying and high-temperature curing.

Comparative Studies on Thermal, Mechanical, and Flame Retardant Properties of PBT Nanocomposites via Different Oxidation State Phosphorus-Containing Agents Modified Amino-CNTs.

High-performance poly(1,4-butylene terephthalate) (PBT) nanocomposites have been developed via the consideration of phosphorus-containing agents and amino-carbon nanotube (A-CNT). One-pot functionalization method has been adopted to prepare functionalized CNTs via the reaction between A-CNT and different oxidation state phosphorus-containing agents, including chlorodiphenylphosphine (DPP-Cl), diphenylphosphinic chloride (DPP(O)-Cl), and diphenyl phosphoryl chloride (DPP(O₃)-Cl). These functionalized CNTs, DPP(O)-A-CNTs ( = 0, 1, 3), were, respectively, mixed with PBT to obtain the CNT-based polymer nanocomposites through a melt blending method.

[Clinical features and treatment of acute clenbuterol poisoning in children].

Objective: To study clinical features, treatment and curative effects in children with acute clenbuterol poisoning, in order to provide a basis for early diagnosis and treatment.

Methods: Clinical data of 28 hospitalized children with acute clenbuterol poisoning in April 2011 were retrospectively studied.

Results: Of the 28 patients, there were 15 males and 13 females, aged 1 to 13 years (mean age 6.

[Role of Treg/Th17 balance in the pathogenesis of cytomegalovirus infection].

Aim: To investigate the role of Treg/Th17 balance in the immune-regulated mechanism of cytomegalovirus (CMV) infection.

Methods: According to the diagnostic criteria of the CMV infection, the patients with CMV infection were divided into the activate infection group and the latent infection group, and the normal children were recruited as control group. The percents of Treg and Th17 in peripheral blood were detected by flow cytometry to calculate Treg/Th17 ratio.

[Report of the first human case of H5N1 avian influenza pneumonia in Hunan, China].

Objective: To summarize and analyze the clinical characteristics and diagnostic and therapeutic measures for the first human case of H5N1 avian influenza pneumonia in mainland of China.

Methods: The clinical data of the first case of H5N1 avian influenza virus infection in China were analyzed and summarized.

Results: The case is a 9-year old boy, who developed acute symptoms of a light common respiratory infection, including fever and dry cough without obvious catarrh.
