Blue-shifted ancyromonad channelrhodopsins for multiplex optogenetics

open access: goldeLife
Abstract Light-gated ion channels from protists (channelrhodopsins or ChRs) are optogenetic tools widely used for controlling neurons and cardiomyocytes. Multiplex optogenetic applications require spectrally separated molecules, which are difficult to engineer without disrupting channel function.

Excitonic structure and pumping power dependent emission blue-shift of type-II quantum dots. [PDF]

open access: yesSci Rep, 2017
In this work we study theoretically and experimentally the multi-particle structure of the so-called type-II quantum dots with spatially separated electrons and holes.

Discovery of Stishovite in the Prismatine-Bearing Granulite from Waldheim, Germany: A Possible Role of Supercritical Fluids of Ultrahigh-Pressure Origin

open access: yesGeosciences, 2022
For the first time in the sixty years since the synthesis of stishovite, we report unambiguous evidence of stishovite formed in the deep Earth. A minimum pressure of about 7.5 GPa at 1000 °C is necessary for the formation of stishovite, corresponding to ...

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.

High Hydrogen Ion Concentration Causes a Blue Shift in Gold Nanoparticles

open access: yesCrystals, 2021
In this research, our team used a rare electrochemical method to obtain gold nanoparticles (GNPs). The growth solution has been added with nitric acid in order to observe the effect of GNPs. The solution also included cetyltrimethylammonium bromide (CTAB)

Relation between Halogen Bond Strength and IR and NMR Spectroscopic Markers

open access: yesMolecules, 2023
The relationship between the strength of a halogen bond (XB) and various IR and NMR spectroscopic quantities is assessed through DFT calculations. Three different Lewis acids place a Br or I atom on a phenyl ring; each is paired with a collection of N ...

Dynamic Responses of Cylindrical Whispering Gallery Mode Revealed by Axial Liquid Disturbance

open access: yesIEEE Photonics Journal, 2020
Cylindrical whispering gallery mode (WGM) microresonators have achieved much attention in the sensing field due to high sensitivity, compatibility and integration. The excitation of spiral modes in such a resonator is unavoidable, causing the axial field

Fabrication of Self-Assembling Carbon Nanotube Forest Fishnet Metamaterials

open access: yesNanomaterials, 2022
The investigation of the preparation of polystyrene (PS) nanosphere monolayers for the fabrication of carbon nanotube (CNT) forest fishnet metamaterial structures is studied in this paper, as a cheap alternative for top-down patterning methods.

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 ...

Observation of Ultrashort Laser Pulse Evolution in a Silicon Photonic Crystal Waveguide

open access: yesMicromachines, 2021
Using the sum frequency generation cross-correlation frequency-resolved optical gating (SFG-XFROG) measurement setup, we observed the soliton evolution of low energy pulse in an Si photonic crystal waveguide, and it exhibited the pulse broadening, blue ...
