Robust room temperature perpendicular magnetic anisotropy and anomalous Hall effect of sputtered NiCoOfilm.

Inverse spinel ferrimagnetic NiCoO(NCO) exhibits volatile physical properties due to the complex ion/valence occupation, which complicates the study its intrinsic properties. In this work, robust room temperature perpendicular magnetic anisotropy (PMA) is distinctly observed in high-quality RF-sputtered NCO film down to 3 uc (2.4 nm), confirmed by the room temperature anomalous Hall effect.

Tuning Bienenstock-Cooper-Munro learning rules in a two-terminal memristor for neuromorphic computing.

In memristors, the implementation of the Bienenstock-Cooper-Munro (BCM) learning rule plays a significant role in the modulation balance of artificial synapses and the reduction of energy consumption owing to their sliding frequency threshold. At present, the BCM learning rule is mostly achieved by adjusting gating voltage or channel current in field effect transistors. However, owing to the lack of the tunable degrees of freedom, the progress of two-terminal memristors is limited to simulating the BCM learning rule.

Diamond anvil cell with double coaxial chambers.

In general, pressure calibration in diamond anvil cells (DACs) has been achieved by mixing pressure calibration materials (PCMs) with the sample inside the pressure chamber. However, the chemical reactions between the sample and PCMs are sometimes unavoidable at extreme conditions, such as high pressure and high temperature. These undesired reactions will cause pollution, induce changes in physical properties or phase transformations of PCMs, and result in tremendous error of pressure calibration.

Overexpression of a Banana Aquaporin Gene Enhances Tolerance to Multiple Abiotic Stresses in Transgenic Banana and Analysis of Its Interacting Transcription Factors.

Molecular identification of the key starch branching enzyme-encoding gene and its interacting transcription factors in banana fruits.

Starch branching enzyme (SBE) has rarely been studied in common starchy banana fruits. For the first time, we report here the molecular characterization of seven () and six () genes in the banana A- and B-genomes, respectively, which could be classified into three distinct subfamilies according to genome-wide identification. Systematic transcriptomic analysis revealed that six s and six s were expressed in the developing banana fruits of two different genotypes, BaXi Jiao (BX, AAA) and Fen Jiao (FJ, AAB), among which and were highly expressed.
