Raw sodium bentonite (Bent) without preliminary treatments is incorporated as a filler in silicone matrix, from 5 to 100 parts per hundred (pph), by weight, simple mixing solution. The mixtures are processed films and stabilized condensation crosslinking at room temperature. Besides being environmentally safe non-toxic, 30 times cheaper than polydimethylsiloxane (PDMS), so the cost price of com...

Millimeter wave rotational spectroscopy and ab initio calculations are used to explore the potential energy surface of LiOH and LiOD with particular emphasis on the bending states and bending potential. New measurements extend the observed rotational lines to J=7<--6 for LiOH and J=8<--7 for LiOD for all bending vibrational states up to (03(3)0). Rotation-vibration energy levels, geometric expe...

Among the four possible stereoisomers of 3,4-dihydroxy-L-proline,2,3-trans-3,4-trans-3,4-dihydroxy-L-proline (IV) had not been found in nature previously. It has now been detected as a component of virotoxins, toxic peptides of Amanita virosa mushrooms. Because periodate failed to effect an oxidative glycol splitting reaction, the two hydroxyl groups in positions 3 and 4 were expected to be in ...

We establish an exact connection between the Choptuik scaling parameter for the three-dimensional BTZ black hole, and the imaginary part of the quasinormal frequencies for scalar perturbations. Via the AdS/CFT correspondence, this leads to an interpretation of Choptuik scaling in terms of the timescale for return to equilibrium of the dual conformal field theory.

A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...

A compact dual wideband bandpass filter for automotive radar (AR) and 5G millimeter-wave (mmWave) applications with adjustable bandwidths is presented in this work. The based on microstrip dual-mode edge-coupled stub-loaded resonators (SLR). novelty of configuration that it allows independent control the which not obvious many reported SLR-based filters. To achieve an overall size 1.23λ_g× 2.02...

The frequency spectrum of the Casimir force between two plates separated by vacuum as it appears in the Lifshitz formalism is reexamined and generalised as compared to previous works to allow for imperfectly reflecting plates. As previously reported by Ford [Phys. Rev. A 48 (1993) 2962], the highly oscillatory nature of the frequency dependence of the Casimir force points to possibilities for v...

We discuss whether or not local information on the potential energy surface embodied by the distribution of unstable instantaneous normal modes can be used to predict the hopping rates and barrier heights for Zwanzig’s model of self-diffusion @R. Zwanzig, J. Chem. Phys. 79, 4507 ~1983!# in simple liquids. Results from a set of simulations of Lennard-Jones particles done at multiple temperatures...
