How digital platforms affect local entrepreneurial activities: Evidence from the staggered entry of craigslist

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Access to markets is critical for entrepreneurial success, yet many face significant barriers. This study argues that digital platforms functioning as peer‐to‐peer marketplaces can facilitate entrepreneurial activity by improving market access for new ventures.

Atomic‐Scale Insights Into Antisite‐Defect‐Induced Metallicity in Halide Perovskites

Small, EarlyView.
Using an aberration‐corrected scanning transmission electron microscope, we identify that the PbCs antisite defect in CsPbBr3 shortens the Pb─Pb bond by ∼20 pm, and induces local strain and polarization, leading to a semiconductor‐to‐metal transition.

Electrospun PAN Membrane Loaded with AgInP2Se6 Nanosheets for Triboelectric Energy Harvesting

Small, EarlyView.
Exfoliated AgInP2Se6 nanosheets are incorporated into a polyacrylonitrile (PAN) polymer matrix by electrospinning and applied for the first time in a triboelectric nanogenerator (TENG). The hybrid membrane delivers strong electrical output and exhibits reversible humidity sensitivity, responding rapidly to changes in relative humidity.

To Dye or Not to Dye: Unraveling the Impact of Surface Chemistry on Cerium Oxide Nanoparticles–Cell Interactions

Small Science, EarlyView.
Fluorescent dye labeling enables nanoparticle imaging but may subtly alter their surface chemistry and biological behavior. This study compares dye‐labeled and unlabeled cerium oxide nanozymes, revealing changes in cellular uptake kinetics without affecting their final intracellular fate. Combined fluorescence and label‐free electron microscopy imaging
