The discovery of cage hydrides (Y,Ca)H6, (La,Ce)H9, and (La,Y)H10 indicates the appeal ternary as contenders for high-temperature superconductors. Herein, we systematically studied a La-Sr-H system predicted interesting stable metastable at 200 GPa by first-principles calculations. results revealed that LaSrH21 has high superconducting transition temperature (Tc ) 211 K GPa, mainly attributed to its unique H12 rings. LaSrH12, LaSr2H18, LaSr3H24 contain distorted H24 cages exhibit Tc values...

Abstract Pressure engineering can access novel optoelectronic properties and crystal structures in halide perovskite materials with soft lattice. However, such pressure‐induced phenomena are commonly realized under large pressure or difficult to retain at atmospheric pressure, thus severely hindering their prospects practical applications. Herein, the pressure‐treated Mn‐doped/undoped Cs 2 NaBiCl 6 exhibits a largely retained bandgap narrowing of 12.2% relative its initial state via...

All elements that form diatomic molecules, such as ${\mathrm{H}}_{2}$, ${\mathrm{N}}_{2}$, ${\mathrm{O}}_{2}$, ${\mathrm{Cl}}_{2}$, ${\mathrm{Br}}_{2}$, and ${\mathrm{I}}_{2}$, are destined to become atomic solids under sufficiently high pressure. However, revealed by many experimental theoretical studies, these show very different propensity transition paths due the balance of reduced volume, lone pair electrons, interatomic bonds. The study F pressure can illuminate this intricate behavior...

Transition metal nitrides have great potential applications as incompressible and high energy density materials. Various polymeric nitrogen structures significantly affect their properties, contributing to complex bonding modes coordination conditions. Herein, we first report a new manganese polynitride MnN4 with bifacial trans–cis [N4]n chains by treating high-pressure high-temperature conditions in diamond anvil cell. Our experiments reveal that has P-1 symmetry could stabilize the...

Abstract In this paper, we consider the problem of contact parameters (slippage and sinkage) estimation for multi-modal robot locomotion on granular terrains. To describe events in same framework robots operated at different modes (e.g., wheel, leg), propose a unified description robots. We also provide parameter method based CNN DWT (discrete wavelet transformation) techniques verify its effectiveness over types Besides motion modes, paper considers influence slope angles robot’s handing...

Mobile robots need reliable maps for autonomous operation. Traditional SLAM systems, which are mainly developed static scenes, often fail in dynamic environments with moving objects present the scene. Learning based systems suffer from insufficient or inaccurate identification of feature points. This paper proposes a novel real-time RGB-D system, is targeted environments, can further enhance detection and removal. done by fusing panoptic segmentation geometry information. The system includes...

Hydrogen-rich compounds have long been considered as one of the hotspot materials for achieving room-temperature superconductivity. We systematically investigate high-pressure phase diagram K-H system and identified two unreported clathrate extreme superhydrides KH20 KH30, hosting high superconducting transition temperatures (Tc) 283 243 K at 500 GPa, respectively.

The mobile robot will move continually with the ground in various unstructured environments, and it inevitably be affected by terrain geometry type (physical property). As a result, detection classification skills are critical demand extra attention order to assure reliability of control navigation. For analysis specific tasks, previous work has always used vision-based non-contact sensors or proprioceptive contact-based (e.g., IMU force sensors), even though vision is not robust against...
