Solvent engineering for scalable fabrication of perovskite/silicon tandem solar cells in air
Nature CommunicationsPerovskite/silicon tandem solar cells hold great promise for realizing high power conversion efficiency at low cost. However, achieving scalable fabrication of wide-bandgap perovskite (~1.68 eV) in air, without the protective environment of an inert ...

Graphs and Combinatorics, 2020 For any graph $G$, let $ι_{\rm c}(G)$ denote the size of a smallest set $D$ of vertices of $G$ such that the graph obtained from $G$ by deleting the closed neighbourhood of $D$ contains no cycle. We prove that if $G$ is a connected $n$-vertex graph that is not a triangle, then $ι_{\rm c}(G) \leq n/4$. We also show that the bound is sharp. Consequently,

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Twitter discourse around competitive cycling and sport-related concussion [PDF]
, 2022 The purpose of this study was to explore the cycling community’s online interactions with sports-related concussion within competitive cycling. Through an analysis of twitter data (n=196), this study examined the discourse related to the problem of ...

Transportation Research Interdisciplinary PerspectivesWhat are the effects of cycling infrastructure? This question is crucial as cities begin to give more space to cycling. In this paper, we propose to use the theoretical concept of affordance to consider not only what a cycle lane affords (or enables ...

Phosphoinositides and inositol phosphates as molecular glues
FEBS Letters, EarlyView.Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells
