Red-Shift Effect and Sensitive Responsivity of MoS2/ZnO Flexible Photodetectors. [PDF]

open access: yesNanoscale Res Lett, 2015
The optoelectronic characteristics of molybdenum disulfide (MoS2)/ZnO flexible photodetectors are investigated. A red-shift effect and improved photocurrent properties of the flexible devices are demonstrated.

Doppler effect tailoring: extra-red shift of structured light [PDF]

open access: yesNature Communications
Doppler effect is a universal phenomenon that describes the frequency shift of waves when interacting with moving targets. Recent studies suggest that the spatial structures of light beams would provide a modification of the group and phase velocities of

Engineering of mCherry variants with long Stokes shift, red-shifted fluorescence, and low cytotoxicity

open access: goldPLoS ONE, 2017
MCherry, the Discosoma sp. mushroom coral-derived monomeric red fluorescent protein (RFP), is a commonly used genetically encoded fluorophore for live cell fluorescence imaging.

Political risks: the “red shift” in debt sustainability analysis [PDF]

open access: yesRisk Management Magazine, 2020
Political stability and economic policy uncertainty can be key determinants of sovereign debt dynamics, and we show how they can be incorporated in debt sustainability analysis.

DFT Study of conformational flexibilities and interaction profiles of new class of nucleoside analogs having nucleic acid bases pairs (Pyrimidine analogues-Adenine) linked through a 1,2,3-triazole spacer [PDF]

open access: yesOrbital: The Electronic Journal of Chemistry, 2014
DFT calculations predict the existence of three stable conformations (one opened and two closed conformations) of the new class of nucleoside with various substituents (X = H, CH3, F, Cl, and Br).

LHCA4 residues surrounding red chlorophylls allow for fine-tuning of the spectral region for photosynthesis in Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2023
Improving far-red light utilization could be an approach to increasing crop production under suboptimal conditions. In land plants, only a small part of far-red light can be used for photosynthesis, which is captured by the antenna proteins LHCAs of ...

Quntitative structure activity relationship (QSAR) of UV-visible spectrum of some different chalkons [PDF]

open access: yesشیمی کاربردی روز, 2013
  The UV-visible spectrum of some different chalkons with both electron with-drawing and electron-donating groups have been investigated. The results showed that electron with-drawing groups cause Blue-Shift and electron-donating groups cause Red-Shift.
