The Cytoplasmic Domain of the SARS-CoV-2 Envelope Protein Assembles into a β-Sheet Bundle in Lipid Bilayers
(Elsevier, 2023-01-28)
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) envelope (E) protein forms a pentameric ion channel in the lipid membrane of the endoplasmic reticulum Golgi intermediate compartment (ERGIC) of the infected ...
Biphasic concentration patterns in ionic transport under nanoconfinement revealed in steady-state and time-dependent properties
(American Institute of Physics, 2023-02-08)
Ion permeation across nanoscopic structures differs considerably from microfluidics because of strong steric constraints, transformed solvent properties, and charge-regulation effects revealed mostly in diluted solutions. ...
African Swine Fever Virus Gene B117L Encodes a Small Protein Endowed with Low-pH-Dependent Membrane Permeabilizing Activity
(American Society for Microbiology, 2023-05-22)
African swine fever virus (ASFV) is causing a devastating pandemic in domestic and wild swine in Central Europe to East Asia, resulting in economic losses for the swine industry. The virus contains a large double-stranded ...
Hopf bifurcations in electrochemical, neuronal, and semiconductor systems analysis by impedance spectroscopy
(American Institute of Physics, 2022-03-16)
Spontaneous oscillations in a variety of systems, including neurons, electrochemical, and semiconductor devices, occur as a consequence of Hopf bifurcation in which the system makes a sudden transition to an unstable ...
Selective Growth of Layered Perovskites for Stable and Efficient Photovoltaics
(Royal Society of Chemistry, 2018-11)
Perovskite solar cells (PSCs) are promising alternatives toward clean energy because of their high-power
conversion efficiency (PCE) and low materials and processing cost. However, their poor stability under
operation ...
Dynamic Control of Interference Effects Between Optical Filaments through Programmable Optical Phase Modulation
(IEEE, 2016-06)
Light beams shaped by programmable megapixel spatial light modulators (SLMs) are key to broadening the applications of photonics. In this paper, we consider the application of a SLM for the generation of two mutually ...
Fluctuation-Driven Transport in Biological Nanopores. A 3D Poisson–Nernst–Planck Study
(MDPI, 2017)
Living systems display a variety of situations in which non-equilibrium fluctuations
couple to certain protein functions yielding astonishing results. Here we study the bacterial channel
OmpF under conditions similar to ...
Tunable hysteresis effect for perovskite solar cells
(Royal Society of Chemistry, 2017-09-14)
Perovskite solar cells (PSCs) usually suffer from a hysteresis effect in current–voltage measurements,
which leads to an inaccurate estimation of the device e
fficiency. Although ion migration, charge trapping/
detrapping, ...
Big dynorphin is a neuroprotector scaffold against amyloid β-peptide aggregation and cell toxicity
(Elsevier, 2022)
Amyloid β-peptide (Aβ) misfolding into β-sheet structures triggers neurotoxicity inducing Alzheimer’s disease (AD). Molecules able to reduce or to impair Aβ aggregation are highly relevant as possible AD treatments since ...
Diffraction-Based Phase Calibration of Spatial Light Modulators With Binary Phase Fresnel Lenses
(IEEE, 2016)
We propose a simple and robust method to determine the calibration function of phase-only spatial light modulators (SLMs). The proposed method is based on the codification of binary phase Fresnel lenses (BPFLs) onto an ...
