Designing High Interfacial Conduction beyond Bulk via Engineering the Semiconductor-Ionic Heterostructure CeO/BaZrYO for Superior Proton Conductive Fuel Cell and Water Electrolysis Applications.

Proton ceramic fuel cells (PCFCs) are an emerging clean energy technology; however, a key challenge persists in improving the electrolyte proton conductivity, e.g., around 10-10 S cm at 600 °C for the well-known BaZrYO (BZY), that is far below the required 0.

gene as a novel pathogenic mutation occurring during the transformation of colorectal adenoma into colorectal cancer.

Background: Polyps may develop into colorectal cancer (CRC) after 10-20 years. The occurrence of polyps and tumors caused by somatic gene mutations is considered a main pathogenesis of CRC. Among all general patients with polyps or CRC, some had adenoma of varying degrees that were consistent with familial colorectal adenomas.

Self-assembly of single amino acid/pyrene conjugates with unique structure-morphology relationship.

This article describes the self-assembly of π-conjugated building blocks composed of single amino acid and pyrene (Py) moieties. In aqueous conditions, the Py-capped amino acids undergo self-assembly through various non-covalent interactions such as hydrogen-bonding, π-π stacking as well as electrostatic interactions to form supramolecular nanostructures in acidic and basic conditions. Interestingly, we found that the blend of different Py-gelators with oppositely charged amino acids (Py-Glu and Py-Lys) displays unique nano-structural morphologies and gelation properties of the resulting hydrogels at physiological pH when compared with single Py conjugates, which was attributed to additional electrostatic interactions.

Expression of Krüppel-like factor 4 in breast cancer tissues and its effects on the proliferation of breast cancer MDA-MB-231 cells.

The aim of the present study was to detect the expression of Krüppel-like factor 4 (KLF4) in breast cancer tissues and to evaluate the effect on the proliferation of breast cancer MDA-MB-231 cells. The expression of KLF4 protein in 239 breast cancer tissues and 40 paracancerous tissues were detected by an immunohistochemical assay, and its correlation with clinical pathological parameters was analyzed. A eukaryotic expression vector, pcDNA3.

P2-Na2/3Ni1/3Mn5/9Al1/9O2 Microparticles as Superior Cathode Material for Sodium-Ion Batteries: Enhanced Properties and Mechanisam via Graphene Connection.

As a promising alternative for lithium ion batteries, room-temperature sodium ion batteries (SIBs) have become one significant research frontier of energy storage devices although there are still many difficulties to be overcome. For the moment, the studies still concentrate on the preparation of new electrode materials for SIBs to meet the applicability. Herein, one new P2-Na2/3Ni1/3Mn5/9Al1/9O2 (NMA) cathode material is successfully prepared via a simple and facile liquid-state method.
