Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

Advanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.

Impact of Secondary Prevention on Mortality in the Building Trades National Medical Screening Program: Effectiveness of Occupational High‐Risk Management

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Since 1997 the Building Trades National Medical Screening Program (BTMed) has offered medical exams to construction workers employed in US nuclear weapons facilities. The process consists of two steps: (1) a detailed work history interview; and (2) a medical exam.

Dual Modality Semiconducting Polymer Nanoparticles for Use in Optical and Magnetic Resonance Imaging

Advanced NanoBiomed Research, EarlyView.
Well‐defined dual‐modality semiconducting polymer nanoparticles composed of red‐emitting conjugated polymers functionalized with novel gadolinium‐based contrast agents have been prepared. The assemblies show a greatly enhanced relaxivity performance compared to the clinical standard, Dotarem, while offering ultrabright fluorescence, ideal for optical ...

Management and research efforts are failing dolphins, porpoises, and other toothed whales

Scientific Reports
Despite being subject to intensive research and public interest many populations of dolphins, porpoises, and other toothed whales (small cetaceans) continue to decline, and several species are on the verge of extinction. We examine small cetacean status,

Bis(2‐amino‐5‐thienyl)Ketone as Oxygen Tolerant Sensitizer for Conventional Radical Photopolymerization

Angewandte Chemie International Edition, EarlyView.
Bis(2‐amino‐5‐thienyl)ketones operate as sensitizer in multi‐component photoinitiating systems using either diaryl iodonium cation or amino benzoates as coinitiators to initiate conventional radical polymerization following either oxidative or reduction photoinduced electron transfer protocol, respectively.

A 150‐Year Avian Extinction Debt Forewarns a Global Species Crisis and Highlights Conservation Opportunities

Conservation Letters
Humans have caused pervasive wildlife habitat loss by transforming most of the Earth's terrestrial surface, while unexpectedly limited species have consequently gone extinct.
