Journal ArticleDOI
The effect of Al on the hydrogen sorption mechanism of LiBH4
O. Friedrichs,Ji Woo Kim,Ji Woo Kim,Ji Woo Kim,Arndt Remhof,F. Buchter,Andreas Borgschulte,Dirk Wallacher,Young Whan Cho,Maximilian Fichtner,Kyu Hwan Oh,Andreas Züttel +11 more
TL;DR: It is demonstrated that at low hydrogen pressures the reaction of LiH and Al gives LiAl under release of hydrogen, which increases the total hydrogen storage capacity, since it also contributes to the LiBH(4) formation in the absorption process.
Journal ArticleDOI
Extreme wettability of nanostructured glass fabricated by non-lithographic, anisotropic etching.
TL;DR: A novel non-lithographic method for the fabrication of nanostructures on glass that introduces a sacrificial SiO2 layer for anisotropic plasma etching and achieves a superhydrophobic surface.
Journal ArticleDOI
UV-responsive nano-sponge for oil absorption and desorption
Do Hyun Kim,Min Chan Jung,So-Hye Cho,Sang Hoon Kim,Ho-Young Kim,Heon Ju Lee,Kyu Hwan Oh,Myoung-Woon Moon +7 more
TL;DR: A novel method is reported to fabricate a nano-sponge which is composed of hydrophobic hydrocarbon and hydrophilic TiO2 nanoparticles for oil absorption or desorption that are responsive to UV irradiation that can be applied for oil-water separation, oil spill cleanup and reuse of spilled oil.
Journal ArticleDOI
Analysis of deformation texture inhomogeneity and stability condition of shear components in f.c.c. metals
TL;DR: In this article, the stability condition of these components was calculated based on the full constraint Taylor-Bisho-Hill theory and could be described by a parameter d{var_epsilon}{sub 13}/d{var _epsilone}{sub 11} with the suffixes 1 and 3 indicating the rolling and thickness directions, respectively.
Journal ArticleDOI
Measurements of stress and fracture in germanium electrodes of lithium-ion batteries during electrochemical lithiation and delithiation
TL;DR: In this article, the authors measured the stresses that develop in sputter-deposited amorphous Ge thin films during electrochemical lithiation and delithiation, and determined the fracture energies are Γ = 8.0 ǫm−2 for a-Li 0.3Ge and Γ ǔ = 5.6 Ôm−1 for a -Li 1.6Ge.
