Abstract Multi‐heteroatom‐doped metal‐free carbons with well‐tailored electronic structures are regarded as promising oxygen reduction reaction (ORR) catalysts. However, their active sites often hindered by the carbon matrix, resulting in reduced catalytic activity. Herein, nitrogen, phosphorus, and sulfur tri‐doped hollow hierarchical porous nanofibers (NPS‐HPCNFs) interpenetrated pores synthesized using a facile coaxial electrospinning method. The distinctive steric confinement induced...
Abstract Oxygen reductions and evolution reactions (ORR/OER) are pivotal electrochemical processes in fuel cells metal‐air batteries, yet the rapid, large‐scale production of efficient ORR/OER electrocatalysts remains challenging. Herein, a groundbreaking microwave‐synthesis strategy is presented that enables rapid facile preparation kilogram‐scale electrocatalysts. The unique microwave irradiation generates instantaneous thermal energy, facilitating formation nano‐carbon bridges...
This letter presents a miniature manipulator with variable stiffness towards minimally invasive transluminal endoscopic surgery, such as the submucosal dissection (ESD). The comprises hollow modules holes in sidewall, compact 4 mm diameter, and dexterous six degrees of freedom (DOFs). Basic operations grasping stripping can be achieved via terminal surgical tools. flexible tubes torque coils are adopted to avoid motion coupling joints. worm gears an anti-backdrive property used transfer...
We have developed a process to fabricate arbitrary-shaped, three-dimensional microstructures in 0.4 Ω cm p-type silicon using focused high-energy proton beam irradiation, followed by electrochemical anodization. This has enabled us produce free-standing complex such as arrays or long wires, grids, wheels, vertically stacked wires and which can be controllably bent upward downward the vertical plane. The two most important factors determine wire cross-section dimensions depth are irradiation...
Force sensing plays an important role in minimally invasive surgery, which enables surgeons to differentiate tissue stiffness and apply appropriate manipulation forces avoid additional damages. However, due size constraints, the implementation of force on surgical instruments is very difficult. In this paper, a novel type forceps consisting double grippers proposed for directly measuring 3-D pulling grasp at tips instrument robot-assisted system. For design forceps, new structural decoupling...
SUMMARY This paper presents a new type of forceps that consist two microgrippers with the capability direct force sensing, which enables grasping and manipulating forces at tip surgical instrument for minimally invasive robotic surgery. For prototype design forceps, double E-type vertical elastomer four strain beams is presented, whose force-sensing principle expounded. Thus, can be considered compliant component, provides tiny displacements allow large strain, overall diameter 10 mm. The...
Prostate biopsy procedures as a gold standard for early screening of prostate cancer often suffer from multipass needle perforations to irrelevant perineal tissue, high complication risk, and time consumption. To address these challenges, this article proposes transurethral robot that can deliver flexible inside the different angles thus obtain tissue samples multiple locations. Emphasis is on design validation with detailed introduction working principle, mechanism modeling, function...
This paper presents an Unscented Kalman Filter (UKF)-based method to achieve high-precision motion estimation of cable-driven forceps for a robot-assisted surgical system. We analyze the operational/working principle revolute joints 3-degree-of-freedom (3-DOF) manipulator. Then gripper jaw is selected as representative joint, which actuated by single-motor mechanism with reset spring. The corresponding system dynamics comprehend mass, elasticity, damping, and friction steel cables. By using...
By the similarity reduction and Darboux transformation, we derive higher-order modes of three-dimensional Bose–Einstein condensate modulation instability in nonautonomous Gross–Pitaevskii equation manipulate them by regulating time-dependent potential gain. Firstly, reduction, (3+1)-dimensional reduces to a (1+1)-dimensional standard nonlinear Schrödinger with constant coefficients. Then, considering Akhmediev breather solution as first-order instability, achieve Nth-order (N = 2, 3, 4, 5)...
By using a multipulse femtosecond pump-probe technique, we achieved an in situ characterization of terahertz wave shaping the periodically poled Mg:LiNbO3 crystal. The analysis method, which includes fast-Fourier transform (frequency spectrum) and Morlet wavelet (time-frequency that detailed information on waves, is demonstrated.
Parallel robot needs to implement the position and orientation calibration before being put into application, due errors from manufacture assembly. Traditional methods with help of non-contact high-precision measuring devices, such as sensors three coordinate instrument, possess many drawbacks including difficult installation, system complexity, high cost low automation. To overcome these issues, this paper presents a method realize kinematic image tracking posture based on computer vision...
Terahertz (THz) wave generation in a periodically poled Mg:LiNbO3 crystal was detected by pump-probe technique and analyzed using frequency time-frequency spectra. Multifrequency THz waves were clearly observed, providing information about the domain structure of crystal. A theoretical T-function model used to fit spectrum. method that can characterize detailed capabilities inner crystal's parts is proposed.

Background: Coronavirus disease 2019 (COVID-19) is a respiratory infectious caused by new coronavirus called severe acute syndrome 2 (SARS-CoV-2). It was first reported in Wuhan, China at the end of 2019, and quickly developed into global pandemic. By reviewing clinical data 1 patient with cryptococcus pneumoniae infection after recovered from COVID-19 relevant literature, following possible consequences were discussed corresponding management strategies proposed.
