We investigate by first-principles molecular dynamics the structural properties of liquid GeSe4, i.e., GexSe1-x at x = 0.2. This composition is very close to the so-called stiffness threshold composition, at which dramatic changes in a series of experiment ...
The detection of higher modes of oscillation in atomic force microscopy can provide additional information on sample properties. However, the limited bandwidth of the photodiode in the beam deflection detection technique often limits the detectable frequen ...
A tensegrity is a lightweight space reticulated structure consisting of compression members — struts — surrounded by a network of tension members — cables — that provide rigidity and stability. They can be easily dismantled and therefore, they provide inno ...
The design of a diffration grating used as an output coupler for a Fabry-Perot resonator is presented. We then consider the problem of determining the distortion and the cross-polarization of the incident Gaussian beam. Different types of gratings and plan ...
When heated in the presence of phosphoryl chloride, 2-anilinovinyl perfluoroalkyl ketones [e.g., 4-anilino-1,1,1-trifluoro-3-buten-2-one] gave 2-(perfluoroalkyl)quinolines [e.g., 2-(trifluoromethyl)quinoline]. As revealed by cross-over expts., an efficient ...
The dielectric behavior and structure of the Sr(Zn1/3Nb2/3)O3-Ba(Zn1/3Nb2/3)O3 solid solution have been investigated with the intention of understanding the relationship between the structural changes and the temperature coefficient of the relative permitt ...
Mol. dynamics simulations (MDS) of the structural rearrangements on the pathway leading to procaspase 3 (I) activation are presented. A retrostructural approach was used to build I from mature caspase 3 (II). The peptide bond that was cleaved during enzyme ...
The vibration-reduction and sound-absorption properties of a truss-core sandwich beam are analyzed. The core is composed by the assembly of unit cells across both the length and thickness of the proposed beam. The cells have chiral geometry which features ...
The electrical conductivity of metallic foams varies strongly with porosity. Data are presented for replicated open-pore microcellular metal over a wide range of relative density. These data, together with data from the literature for different foam struct ...
