Intrinsic pinning by naturally occurring correlated defects in FeSe1-xTex superconductors
(IOP Publishing, 2017-07-12)
We study the angular dependence of dissipation in the superconducting state of FeSe and Fe(Se1-xTex) through electrical transport measurements, using crystalline intergrown materials. We reveal the key role of the inclusions ...
Further insight on recombination losses in the intrinsic layer of a-Si:H solar cells using computer modeling tools
(American Institute of Physics, 2017-05)
Recombination losses of a-Si:H based p-i-n solar cells in the annealed state are analyzed with device computer modeling. Under AM1.5 illumination, the recombination rate in the intrinsic layer is shown to be controlled by ...
A polaronic stacking fault defect model for CaCu3Ti4O12 material: an approach for the origin of the huge dielectric constant and semiconducting coexistent features
(IOP Publishing, 2009-02-09)
This paper proposes a polaronic stacking fault defect model as the origin of the huge dielectric properties in CaCu3Ti4O12 (CCTO) materials. The model reconciles the opposing views of researchers on both sides of the ...
Asn441 plays a key role in folding and function of the Na+/I− symporter (NIS)
(Federation of American Societies for Experimental Biology, 2013-05)
The Na+/I− symporter (NIS) is a plasma membrane glycoprotein that mediates active I− transport in the thyroid, the first step in the biosynthesis of the iodine-containing thyroid hormones T3 and T4. Several NIS mutants ...
Optomechanical many-body cooling to the ground state using frustration
(American Physical Society, 2016-08)
We show that the vibrations of an ion Coulomb crystal can be cooled to the zero-point motion through the optomechanical coupling with a high-finesse cavity. Cooling results from the interplay between coherent scattering ...
Exciton diffusion, antenna effect, and quenching defects in superficially dye-doped conjugated polymer nanoparticles
(American Chemical Society, 2021-10)
Energy transfer (ET) in conjugated polymer nanoparticles (CPNs) is a critical process that affects the performance of these materials in diverse applications such as biological−chemical− physical sensing, imaging, ...
How far does the defect tolerance of lead-halide perovskites range? The example of Bi impurities introducing efficient recombination centers
(Royal Society of Chemistry, 2019-03)
One of the key properties of lead-halide perovskites employed in solar cells is the defect tolerance of the materials, in particular regarding intrinsic point defects, which mainly form shallow traps. Considering that high ...
Mitotic and pheromone-specific intrinsic polarization cues interfere with gradient sensing in Saccharomyces cerevisiae
(National Academy of Sciences, 2020-03)
Polarity decisions are central to many processes, including mitosis and chemotropism. In Saccharomyces cerevisiae, budding and mating projection (MP) formation use an overlapping system of cortical landmarks that converges ...
Lrig1 is a cell-intrinsic modulator of hippocampal dendrite complexity and BDNF signaling
(Nature Publishing Group, 2016-04)
Even though many extracellular factors have been identified as promoters of general dendritic growth and branching, little is known about the cell-intrinsic modulators that allow neurons to sculpt distinctive patterns of ...
