New Journal of Physics, 2022 A drop in the efficiency of light-emitting diodes based on InGaN/GaN QWs known as the ‘green gap’ has been studied intensively over the past dozen years. Several factors were revealed to contribute to its origin, such as random fluctuations in the indium

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

CH3NH3PbBr3 is not pyroelectric, excluding ferroelectric-enhanced photovoltaic performance
APL Materials, 2016 To experimentally (dis)prove ferroelectric effects on the properties of lead-halide perovskites and of solar cells, based on them, we used second-harmonic-generation spectroscopy and the periodic temperature change (Chynoweth) technique to detect the ...

Metals, 2017 Grain boundary grooves are common features on polycrystalline solid–liquid interfaces. Their local microstructure can be closely approximated as a “variational” groove, the theoretical profile for which is analyzed here for its Gibbs–Thomson thermo ...

Frontiers in PsychologyThe current stage of consciousness science has reached an impasse. We blame the physicalist worldview for this and propose a new perspective to make progress on the problems of consciousness. Our perspective is rooted in the theory of conscious agents. We thereby stress the fundamentality of consciousness outside of spacetime, the importance of agency,

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Charging dynamics of an individual nanopore
Nature Communications, 2018 Modern energy-storage technologies are based on porous electrodes that store charge within nanometrically-narrow pores or slits. Here the authors show an approach to probe and measure, for the first time, the charging dynamics within an individual nano ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
