Sebum Components Dampen the Efficacy of Skin Disinfectants against Cutibacterium acnes Biofilms

open access: yesMicroorganisms
At Canadian Blood Services, despite the use of 2% chlorhexidine and 70% isopropyl alcohol (standard disinfectant, SD) prior to venipuncture, Cutibacterium acnes evades eradication and is a major contaminant of platelet concentrates (PCs). Since C.

Toposelective Functionalization of Solution‐Processed Transition Metal Dichalcogenides with Metal Nanoparticles via Defect Engineering

open access: yesAdvanced Materials, EarlyView.
This work presents a novel strategy for toposelective functionalization of solution‐processed transition metal dichalcogenides with noble metal nanoparticles via galvanic displacement. Owing to the selective edge decoration with gold, palladium, or platinum nanoparticles, the hybrid materials exhibit new properties and improved device performance in ...

Backlogs are a dynamic system, not a warehousing problem

open access: yesForensic Science International: Synergy, 2020
Addressing casework backlogs would seem to represent “low hanging fruit” for increasing offender apprehension and improving justice. Yet, after years of grant funding for backlog reduction and capacity building, backlogged cases, especially DNA cases ...

The Role of Dynamic Solvent Swelling in Electrochemical Doping of Semiconducting Polymers

open access: yesAdvanced Materials Interfaces, EarlyView.
Solvent swelling in organic electrolytes dynamically evolves during electrochemical doping of poly(3‐hexylthiophene) (P3HT); multiple polymers, ranging from highly regioregular to fully regiorandom, demonstrate how crystallinity controls swelling.

Performance of Portfolios Based on the Expected Utility-Entropy Fund Rating Approach

open access: yesEntropy, 2021
Yang and Qiu proposed and reframed an expected utility–entropy (EU-E) based decision model. Later on, a similar numerical representation for a risky choice was axiomatically developed by Luce et al. under the condition of segregation.

Direct Growth of Rectangular 2D Layered Metal‐Halide Perovskite Microcrystal Photonic Cavities on Functional Substrates

open access: yesAdvanced Optical Materials, EarlyView.
A simple and scalable method to fabricate 2D layered metal halide microcrystals with rectangular shape, extremely flat surfaces, and submicron thickness is presented. The growth occurs in evaporating droplets on planar substrates, which enables the fabrication of the microcrystals directly on functional surfaces. The microcrystals demonstrate excellent
