Abstract Prussian blue analogues (PBAs) are a class of promising materials for capacitive deionization. However, the kinetic mismatch between their slow ion storage rate and demand from short‐time desalination severely limits performance. Here, group structure‐tuneable Ni‐Mn PBAs have been developed by combination strategy surface‐protected chemical etching Ostwald ripening to study kinetics. Treating them as demos, characterizations investigations, e.g., in situ XRD three‐electrode system,...

Tieguanyin (TGY) is one kind of oolong tea that widely appreciated for its aroma and taste. To study the difference volatile compounds among different types TGY other teas, solid-phase microextraction–gas chromatography–mass spectrometry chemometrics analysis were conducted in this experiment. Based on variable importance projection > 1 character impact 1, contents heptanal (1.60–2.79 μg/L), (E,E)-2,4-heptadienal (34.15–70.68 (E)-2-octenal (1.57–2.94 indole (48.44–122.21 (E)-nerolidol...

Layered double hydroxides (LDHs) are a class of anionic clay materials. When calcined at certain temperature range, LDHs decompose into corresponding mixed metal oxides (Ox), which regarded as promising electrode materials for capacitive deionization (CDI). We have developed simple yet efficient strategy in situ assembly the MgAl-Ox nanosheets on graphene (G). The as-obtained MgAl-Ox/G nanohybrids with numerous channels access anion exhibited high surface area and electrical conductivity....

Asymmetric capacitive mixing (Asy-CapMix) for extracting salinity gradient energy is realized by using oppositely charged carbon electrodes. High performance in terms of voltage rise and average power density achieved.

Abstract Electrochemical nitrate reduction reaction (NO 3 − RR) provides a sustainable and efficient way to producing ammonia at ambient condition denitrifying wastewater. However, NO RR is still confronted with some barriers present, because of the sluggish kinetics competitive hydrogen evolution (HER). Particularly, it requires highly robust selective electrocatalysts, which steers complex multistep reactions toward process. Among various Co‐based electrocatalysts demonstrate rapid...

Organic–inorganic hybrid membranes, made of a high density redox active moieties covalently bonded to the internal surfaces vertically aligned mesoporous silica thin films, are relevant for applications in transparent energy storage devices. This is demonstrated here on basis functionalized films prepared indium–tin oxide electrode from combination an electrochemically induced self-assembly method (to generate azide-functionalized silica) and copper-catalyzed azide–alkyne click reaction...

Parkour is a grand challenge for legged locomotion that requires robots to overcome various obstacles rapidly in complex environments. Existing methods can generate either diverse but blind skills or vision-based specialized by using reference animal data rewards. However, autonomous parkour learn generalizable are both and perceive react scenarios. In this work, we propose system learning single end-to-end policy of simple reward without any motion data. We develop reinforcement method...

New water disinfection technologies should be developed because current methods usually produce by-products and are expensive. Here, we demonstrated the use of a contact-active activated carbon electrode functionalized by quaternary ammonium compound for capacitive deionization (CDID) at contaminant concentration 104 CFU/mL. The effects cell voltage, flow rate, ion on performance CDID were investigated. can kill 99% Escherichia coli or Pseudomonas aeruginosa (with CFU/mL) relatively low...

The search for novel lithium-ion sieves (LISs) with more desirable performance seems to be at the cutting edge of lithium separation from seawater and salt-lake brines. In this work, new types freestanding shape-controllable LISs have been prepared by subtly anchoring λ-MnO2 nanodots on surface mesoporous polyacrylonitrile (PAN) nanoskeletons via a scalable sol–gel method. Synergistic effects originate hierarchically porous polymer structure, high ratio significantly reduces ion-diffusion...

BACKGROUND:The aim of this study was to retrospectively analyze the incidence complications intracranial complex aneurysms embolization by stent-assisted coils, and investigate causes corresponding treatment methods. MATERIAL AND METHODS:A total 71 patients with subarachnoid hemorrhage (SAH) underwent coil from 2015 2018 were enrolled in study. Among them, 59 cases single aneurysm, 12 multiple (11 2 1 case 3 aneurysms), for a 84 aneurysms. All received stent angioplasty except case....

Vertical jump height is widely used for assessing motor development, functional ability, and capacity. Traditional methods estimating vertical rely on force plates or optical marker-based motion capture systems limiting assessment to people with access specialized laboratories. Current wearable designs need be attached the skin strapped an appendage which can potentially uncomfortable inconvenient use. This paper presents a novel algorithm based foot-worn inertial sensors. Twenty healthy...

First, the analysis of developing status wind turbine control strategy has been made; Second, some mathematical models about aerodynamic parts are established according to principle power generating units various parts. At same time, sub-modules in MATLAB. last, based on Fuzzy controller is design and simulated by MATLAB/simulink. Both low speed high output generator can quickly reached a stability (about 4s), which improve system respondent time.
