Heterostructured TiO2 Nanorod@Nanobowl Arrays for Efficient Photoelectrochemical Water Splitting
Small - Tập 12 Số 11 - Trang 1469-1478 - 2016
Wenhui Wang, Jingya Dong, Xiaozhou Ye, Yang Li, Yurong Ma, Limin Qi
Heterostructured TiO2 nanorod@nanobowl (NR@NB) arrays consisting of rutile TiO2 nanorods grown on the inner surface of arrayed anatase TiO2 nanobowls are designed and fabricated as a new type of photoanodes for photoelectrochemical (PEC) water splitting. The unique heterostructures with a hierarchical architecture are readily f...... hiện toàn bộ
Conjugated Polymers for Light‐Activated Antifungal Activity

Chengfen Xing, Gaomai Yang, Libing Liu, Qiong Yang, Fengting Lv, Shu Wang
Bulk Micromachining of Si by Metal‐assisted Chemical Etching
Small - Tập 10 Số 18 - Trang 3761-3766 - 2014
S. B. Kim, Dahl‐Young Khang
Bulk micromachining of Si is demonstrated by the well‐known metal‐assisted chemical etching (MaCE). Si microstructures, having lateral dimension from 5 μm up to millimeters, are successfully sculpted deeply into Si substrate, as deep as >100 μm. The key ingredient of this success is found to be the optimizations of catalyst metal type and its morphology. Combining the respective advanta...... hiện toàn bộ
Surface Design Strategy of Catalysts for Water Electrolysis
Small - Tập 18 Số 27 - 2022
Binghui Zhou, Ruijie Gao, Ji‐Jun Zou, Huaming Yang
AbstractHydrogen, a new energy carrier that can replace traditional fossil fuels, is seen as one of the most promising clean energy sources. The use of renewable electricity to drive hydrogen production has very broad prospects for addressing energy and environmental problems. Therefore, many researchers favor electrolytic water due to its green and low‐cost advant...... hiện toàn bộ
Improving the Oxygen Evolution Activity of Layered Double‐Hydroxide via Erbium‐Induced Electronic Engineering
Small - Tập 19 Số 5 - 2023
Yu Zhu, Xuan Wang, Xiaoheng Zhu, Zixin Wu, Dongsheng Zhao, Fei Wang, Dongmei Sun, Yawen Tang, Hao Li, Gengtao Fu
AbstractLayered double‐hydroxide (LDH) has been considered an important class of electrocatalysts for the oxygen evolution reaction (OER), but the adsorption‐desorption behaviors of oxygen intermediates on its surface still remain unsatisfactory. Apart from transition‐metal doping to solve this electrocatalytic problem of LDH, rare‐earth (RE) species have sprung up...... hiện toàn bộ
Role of MoOx Surficial Modification in Enhancing the OER Performance of Ru–Pyrochlore
Small - Tập 19 Số 10 - 2023
Haibo Liu, Hengyu Guo, Yanan Chen, Zhengping Zhang, Feng Wang
AbstractPyrochlore ruthenate (Y2Ru2O7–δ) is highlighted as a promising oxygen evolution reaction (OER) catalyst for water splitting in polymer electrolyte membrane electrolyzers. However, an efficient electronic modulation strategy for Y2Ru2O7–δ... hiện toàn bộ
Advanced Transition Metal‐Based OER Electrocatalysts: Current Status, Opportunities, and Challenges
Small - Tập 17 Số 37 - 2021
Kexin Zhang, Ruqiang Zou
AbstractOxygen evolution reaction (OER) is an important half‐reaction involved in many electrochemical applications, such as water splitting and rechargeable metal–air batteries. However, the sluggish kinetics of its four‐electron transfer process becomes a bottleneck to the performance enhancement. Thus, rational design of electrocatalysts for OER based on thoroug...... hiện toàn bộ
Cytotoxicity and Immunological Response of Gold and Silver Nanoparticles of Different Sizes
Small - Tập 5 Số 13 - Trang 1553-1561 - 2009
Hung‐Jen Yen, Shan‐hui Hsu, Ching‐Lin Tsai
AbstractThe immunological response of macrophages to physically produced pure Au and Ag nanoparticles (NPs) (in three different sizes) is investigated in vitro. The treatment of either type of NP at ≥10 ppm dramatically decreases the population and increases the size of the macrophages. Both NPs enter the cells but only AuNPs (especially those with smaller diamter)...... hiện toàn bộ
Hierarchical 3D Cobalt‐Doped Fe3O4 Nanospheres@NG Hybrid as an Advanced Anode Material for High‐Performance Asymmetric Supercapacitors
Small - Tập 13 Số 33 - 2017
Meng Guo, Jayaraman Balamurugan, Xuyang Li, Nam Hoon Kim, Joong Hee Lee
Hierarchical nanostructure, high electrical conductivity, extraordinary specific surface area, and unique porous architecture are essential properties in energy storage and conversion studies. A new type of hierarchical 3D cobalt encapsulated Fe3O4 nanosphere is successfully developed on N‐graphene sheet (Co−Fe3O4... hiện toàn bộ
