Phonons at the Γ point and the Raman spectrum of the hexagonal Ge 2 Sb 2 Te 5 were computed within density functional perturbation theory. The three different stackings of the Ge/Sb …
Based on a first-principles calculation combined with the cluster expansion technique and Monte Carlo statistical simulation, the segregation behavior of a Pt 28 Rh 27 cuboctahedral …
0.995[(K 0.50 Na 0.50 ) 0.94 Li 0.06 ]NbO 3 –0.005AETiO 3 (AE=Ca, Sr, Mg, Ba) lead-free piezoelectric ceramics were prepared by normal sintering. The effects of the AETiO 3 and …
When cultured endothelial cells (ECs) are exposed to shear flow, initially cobblestone-like ECs spontaneously elongate and align along the flow direction, acquiring a similar …
CaAl 2 O 4 co-doped with Eu 2+ and Er 3+ were prepared by the solid-state reaction method and investigated for their photoluminescence properties. Broad band UV excited …
Nanometer sized whiskers (nanowires) offer a vehicle for the study of size-dependent phenomena. While quantum-size effects are commonly expected and easily predicted, size …
Ratchet based microwave current generators and detectors were developed in Si/SiGe heterostructures for wireless communication with the possibility of extending the detection limit to …
An experimental study using time-resolved fluorescence techniques together with theoretical simulations has been conducted and used to determine the quenching cross-sections of …
We present the possibility of extracting the strain rate sensitivity, activation volume and Helmholtz free energy (for dislocation activation) using just one indentation stress relaxation test, …
We construct the six-dimensional Lagrangian for the massless twisted open strings with one end-point ending on a stack of D5 and the other on a stack of D9 branes, interacting with the …
