Dual atomic copper‑indium (CuIn) catalysts (CuIn-DACs) have been fabricated by metal-organic framework (MOF) derivation strategy for electrochemical reduction of CO2 to methanol with high selectivity, in which Cu and In atoms are simultaneously introduced MOF. The introduction indium modulates the electronic structure atoms. neighbouring CuIn dual sites inhibit hydrogen evolution reaction promote conversion because synergistic effect between In. CuIn-DACs exhibit higher selectivity than...
The electrocatalytic synthesis of high-value-added urea by activating N2 and CO2 is a green technology that has achieved carbon neutrality. However, the chemical adsorption C–N coupling ability on surface catalyst are generally poor, greatly limiting improvement activity selectivity in synthesis. Herein, novel hierarchical mesoporous CeO2/Co3O4 heterostructures fabricated, at an ultralow applied voltage −0.2 V, yield rate reaches 5.81 mmol g–1 h–1, with corresponding Faraday efficiency...
Abstract The novelties in this paper are embodied the fast interfacial charge transfer α-Fe 2 O 3−δ C δ /FeVO 4−x+δ x−δ @C bulk heterojunctions with controllable phase compositions. carbon source-glucose plays an important role as connecting bridge between micelles solution, forming C-O, C-O-Fe and O-Fe-C bonds through dehydration polymerization reactions. Then extra VO 3 − around FeVO 4 colloidal particles can react unstable Fe(OH) , resulting transformation from (47.99–7.16%) into...
The lack of perception recoil limits the immersion virtual reality first-person shooting games in which users hold a gun their hand. This paper presents design and modeling an ungrounded haptic that could simulate using asymmetric force, is rendered by voice coil actuator produces directional force to rather than vibration feedback. A magnet driven electromagnetic moves forward inside like bullet does corresponding reaction perceived as recoil. spring used reset position magnet, friction...
We present a new approach to address the challenges associated with maintaining functionality of triboelectric vibration sensors in smart plywood during woodworking operations involving nails and screws. The current state-of-the-art sensor design employs non-overlapping electrodes, which unfortunately leads significant compromises terms signal strength clarity, particularly real-world scenarios that involve electromagnetic (EM) interference. To overcome these limitations, we propose method...
Tagnoo is a computational plywood augmented with RFID tags, aimed at empowering woodworkers to effortlessly create room-scale smart environments. Unlike existing solutions, does not necessitate technical expertise or disrupt established woodworking routines. This battery-free and cost-effective solution seamlessly integrates computation capabilities into plywood, while preserving its original appearance functionality. In this paper, we explore various parameters that can influence Tagnoo's...
We investigate the feasibility of a vibrotactile device that is both battery-free and electronic-free. Our approach leverages lasers as wireless power transfer haptic control mechanism, which can drive small actuators commonly used in AR/VR mobile applications with DC or AC signals. To validate our method, we developed proof-of-concept prototype includes low-cost eccentric rotating mass (ERM) motors linear resonant (LRAs) connected to photovoltaic (PV) cells. This enabled us capture laser...
Quality of experience (QoE) has been widely recognized as the primary metric to evaluate user in multimedia applications. However, QoE assessment tactile virtual environments is still highly dependent on subjective measures. Inspired by fact that physiological signals can characterize user's emotional state, we propose a measurement method for reality (VR) with vibrotactile feedback based frontal lobe power asymmetry (FLPA). The score VR used ground truth QoE. selection indicators consists...
