Journal ArticleDOI
High performance supercapacitor for efficient energy storage under extreme environmental temperatures
TL;DR: Li et al. as mentioned in this paper developed a low-cost and high performance supercapacitor utilizing graphene-based electrodes and Li2SO4-based aqueous electrolyte, which showed excellent charge storage characteristics from −20°C to 45°C.
Journal ArticleDOI
Facile Transferring of Wafer-Scale Ultrathin Alumina Membranes onto Substrates for Nanostructure Patterning
Ahmed Al-Haddad,Ahmed Al-Haddad,Zhibing Zhan,Chengliang Wang,Samar Tarish,Samar Tarish,Ranjith Vellacheria,Yong Lei +7 more
TL;DR: Through a unique design of the fabrication and transferring processes, a facile transferring of wafer-scale ultrathin alumina membranes (UTAMs) onto substrates without any twisting, folding, cracking and contamination is achieved.
Journal ArticleDOI
All‐Solid‐State Cable‐Type Supercapacitors with Ultrahigh Rate Capability
Ranjith Vellacheri,Huaping Zhao,Mike Mühlstädt,Ming Jie,Ahmed Al-Haddad,Minghong Wu,Klaus D. Jandt,Yong Lei +7 more
Journal ArticleDOI
Dimensional Dependence of the Optical Absorption Band Edge of TiO2 Nanotube Arrays beyond the Quantum Effect
Ahmed Al-Haddad,Ahmed Al-Haddad,Zhijie Wang,Zhijie Wang,Rui Xu,Haoyuan Qi,Ranjith Vellacheri,Ute Kaiser,Yong Lei +8 more
TL;DR: In this article, geometrical parameters can also be used to manipulate the optical band gap of the TiO2 nanotube arrays, and the authors observed that the optical absorption band edge exhibited a red shift as the diameter of the nanotubes was tuned to be larger and the distance between two Nanotubes became smaller.
Journal ArticleDOI
Synchronous Formation of ZnO/ZnS Core/Shell Nanotube Arrays with Removal of Template for Meliorating Photoelectronic Performance
Samar Tarish,Samar Tarish,Zhijie Wang,Ahmed Al-Haddad,Ahmed Al-Haddad,Chengliang Wang,Adriana Ispas,Henry Romanus,Peter Schaaf,Yong Lei +9 more
TL;DR: In this article, an innovative approach to remove the anodic aluminum oxide (AAO) template completely without any further treatments, just through a subsequent sulfidation process to convert ZnO/AAO nanotubes to zinc oxide/ZnS core/shell nanotube was reported.
