Electromagnetic energy storage and power dissipation in nanostructures

open access: yes, 2014
The processes of storage and dissipation of electromagnetic energy in nanostructures depend on both the material properties and the geometry. In this paper, the distributions of local energy density and power dissipation in nanogratings are investigated ...

Study of the 12C+12C fusion reactions near the Gamow energy [PDF]

open access: yes, 2007
The fusion reactions 12C(12C,a)20Ne and 12C(12C,p)23Na have been studied from E = 2.10 to 4.75 MeV by gamma-ray spectroscopy using a C target with ultra-low hydrogen contamination. The deduced astrophysical S(E)* factor exhibits new resonances at E

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Harmonic resonance analysis in high‐renewable‐energy‐penetrated power systems considering frequency coupling

open access: yesEnergy Conversion and Economics, 2022
Renewable energy is a key solution to address the challenges of energy shortages and climate change. Consequently, high‐renewable‐energy‐penetrated power systems (HREPPS) have become a popular trend.

Non-extensive resonant reaction rates in astrophysical plasmas

open access: yes, 2003
We study two different physical scenarios of thermonuclear reactions in stellar plasmas proceeding through a narrow resonance at low energy or through the low energy wing of a wide resonance at high energy.

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

A simple formula for calculating resonance energy of benzenoid hydrocarbons

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2006
The topological resonance energy (TRE) of a catacondensed benzenoid hydrocarbon with h six-membered rings and K Kekulé structures can be calculated by the (approximate) formula TRE = Ah + B + CK e–Dh, where A = 0.136, B = –0.223, C = 0.281, and D = 0.454.

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Phonon-induced dynamic resonance energy transfer

open access: yesNew Journal of Physics, 2014
In a network of interacting quantum systems, achieving fast coherent energy transfer is a challenging task. While quantum systems are susceptible to a wide range of environmental factors, in many physical settings their interactions with quantized ...

Distinguishing $s^{\pm}$ and $s^{++}$ electron pairing symmetries by neutron spin resonance in superconducting NaFe$_{0.935}$Co$_{0.045}$As [PDF]

open access: yes, 2013
A determination of the superconducting (SC) electron pairing symmetry forms the basis for establishing a microscopic mechansim for superconductivity. For iron pnictide superconductors, the $s^\pm$-pairing symmetry theory predicts the presence of a sharp ...
