Self‐Recovery of Carbonate‐Contaminated Strontium Titanate (100) Vicinal Surfaces Imaged by Tip‐Enhanced Raman Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Strontium titanate, a widely used perovskite material, undergoes changes in surface properties under CO2 adsorption. This study demonstrates a self‐regeneration process where strontium carbonate gradually delaminates, leaving a TiO2 termination. The findings, supported by optical near‐field spectroscopy and density functional theory, have broad ...

Generating Potent Poisons and Backdoors from Scratch with Guided Diffusion [PDF]

open access: yesarXiv
Modern neural networks are often trained on massive datasets that are web scraped with minimal human inspection. As a result of this insecure curation pipeline, an adversary can poison or backdoor the resulting model by uploading malicious data to the internet and waiting for a victim to scrape and train on it.

LEAD-POISONING IN ILLINOIS [PDF]

open access: yesJournal of the American Medical Association, 1911
INTRODUCTION Lead-poisoning in the United States is almost an unknown subject. Go through the literature and you will find here and there the report of an unusual case, an occasional compilation in a text-book, the material for which has had to be drawn from foreign sources; no experimental work, little study of the newer methods of diagnosis and no ...

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.
