Maribacter aquimaris sp. nov., isolated from seawater adjacent to Fildes Peninsula, Antarctica.

A novel Gram-stain-negative, aerobic, and rod-shaped bacterium with gliding motility, named strain ANRC-HE7, was isolated from the seawater of Biological Bay adjacent to Fildes Peninsula, Antarctica. The optimal growth of this strain occurred at 28 °C, pH 7.5, and in the presence of 1.

Constructing a Superlithiophilic 3D Burr-Microsphere Interface on Garnet for High-Rate and Ultra-Stable Solid-State Li Batteries.

Garnet-type solid-state electrolyte (SSE) Li La Zr Ta O attracts great interest due to its high ion conductivity and wide electrochemical window. But the huge interfacial resistance, Li dendrite growth, and low critical current density (CCD) block the practical applications. Herein, a superlithiophilic 3D burr-microsphere (BM) interface layer composed of ionic conductor LiF-LaF is constructed in situ to achieve a high-rate and ultra-stable solid-state lithium metal battery.

Single-Atom Pd-N Catalysis for Stable Low-Overpotential Lithium-Oxygen Battery.

The critical challenge for Li-O batteries lies in the large charge overpotential, leading to undesirable side reactions and inferior cycle stability. Single-atom catalysts have shown promising prospects in expediting the kinetics of oxygen evolution reaction (OER) for Li-O batteries. However, a present practical drawback is the limited understanding of the correlation between the unique atomic structures and the OER mechanism.

A Novel LiDAR-IMU-Odometer Coupling Framework for Two-Wheeled Inverted Pendulum (TWIP) Robot Localization and Mapping with Nonholonomic Constraint Factors.

This paper proposes a method to solve the problem of localization and mapping of a two-wheeled inverted pendulum (TWIP) robot on approximately flat ground using a Lidar-IMU-Odometer system. When TWIP is in motion, it is constrained by the ground and suffers from motion disturbances caused by rough terrain or motion shaking. Combining the motion characteristics of TWIP, this paper proposes a framework for localization consisting of a Lidar-IMU-Odometer system.

Improving Cycling Stability and Rate Capability of High-Voltage LiCoO₂ Through an Integration of Lattice Doping and Nanoscale Coating.

High-voltage LiCoO₂ has attracted much interest owing to the high specific energy density. But the poor cycling performance and inferior rate capacity of LiCoO₂ at a high voltage (≥4.5 V) has restricted the practical applications.

sp. nov., isolated from seawater adjacent to Fildes Peninsula, Antarctica.

A Gram-negative bacterium, namely strain ANRC-JHZ47, was isolated from a seawater sample collected at Biological Bay, Fildes Peninsula, Antarctica. Cells of strain ANRC-JHZ47 were rod-shaped and motile by a single polar flagellum. Strain ANRC-JHZ47 was aerobic, oxidase-negative, and catalase-positive.

Effects of Nano-CeO₂ with Different Nanocrystal Morphologies on Cytotoxicity in HepG2 Cells.

Cerium oxide nanoparticles (nano-CeO₂) have been reported to cause damage and apoptosis in human primary hepatocytes. Here, we compared the toxicity of three types of nano-CeO₂ with different nanocrystal morphologies (cube-, octahedron-, and rod-like crystals) in human hepatocellular carcinoma cells (HepG2). The cells were treated with the nano-CeO₂ at various concentrations (6.

An electrochemical DNA biosensor for evaluating the effect of mix anion in cellular fluid on the antioxidant activity of CeO2 nanoparticles.

CeO2 nanoparticles are of particular interest as a novel antioxidant for scavenging free radicals. However, some studies showed that they could cause cell damage or death by generating reactive oxygen species (ROS). Up to now, it is not well understood about these paradoxical phenomena.

The vital role of buffer anions in the antioxidant activity of CeO2 nanoparticles.

Cerium oxide (CeO(2)) nanoparticles display excellent antioxidant properties by scavenging free radicals. However, some studies have indicated that they can cause an adverse response by generating reactive oxygen species (ROS). Hence, it is important to clarify the factors that affect the oxidant/antioxidant activities of CeO(2) nanoparticles.
