Zero‐Power, Optical Toxic Gas and Vapor Sensors Utilizing Printed Nematic Liquid Crystal Patterns on Selectively Reactive Substrates

open access: yesAdvanced Sensor Research, EarlyView.
Fast response, zero‐power, text or image sensors utilizing light transmission or reflection, and no unfavorable color change judgments, are fabricated using printed nematic liquid crystals patterned on reactive alignment layers, permit ppt‐ to ppb‐level sensitivity, and were field‐tested with active firefighters.

Multiple Roles of Alkanethiolate‐Ligands in Direct Formation of H2O2 over Pd Nanoparticles

open access: yesAngewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
Under the reaction conditions of direct H2O2 formation over alkylthiolate(RS) decorated Pd, we find that the RS is oxidized yielding RSO2 as the effective ligand. The RSO2 ligand shows superior ability for proton transfer to the intermediate surface species OOH, which accelerates the formation of H2O2.

Chronic Lead Exposure in Adult Mice: Associations with miR-671/CDR1as Regulation, NF-κB Signaling, and Alzheimer’s Disease-like Pathology

open access: yesToxics
Long-term exposure to lead (Pb) can result in chronic damage to the body through accumulation in the central nervous system (CNS) leading to neurodegenerative diseases, such as Alzheimer’s disease (AD).

Advances in Nano‐Immunomodulatory Systems for the Treatment of Acute Kidney Injury

open access: yesAdvanced Science, EarlyView.
Based on the biodegradability and the immunological reactiveness, IMNs can be broadly classified into four categories. The first category includes types of biologically derived materials that cause immunomodulatory action and biodegradability like nanoparticles of cell membranes, extracellular vesicles, and exosomes.

Edge‐hosted Atomic Co−N4 Sites on Hierarchical Porous Carbon for Highly Selective Two‐electron Oxygen Reduction Reaction

open access: yesAngewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
The edge‐hosted Co−N4 sites in the carbon matrix are more efficient and selective than basal plane‐hosted ones in catalyzing 2 e−‐ORR, achieving a remarkable selectivity of ≈95 % in the electrochemical production of H2O2. Abstract Not only high efficiency but also high selectivity of the electrocatalysts is crucial for high‐performance, low‐cost, and ...

Human exposure to trichloroethylene is associated with increased variability of blood DNA methylation that is enriched in genes and pathways related to autoimmune disease and cancer

open access: yesEpigenetics, 2019
Human exposure to trichloroethylene (TCE) is linked to kidney cancer, autoimmune diseases, and probably non-Hodgkin lymphoma. Additionally, TCE exposed mice and cell cultures show altered DNA methylation. To evaluate associations between TCE exposure and
