Journal of Radioanalytical and Nuclear Chemistry, 2018 Uranium and polonium isotopes were measured in tap water and groundwater from the Warsaw area (Poland). The mean values of 210Po, 234U and 238U in surface intakes were 0.12, 3.91 and 2.75 mBq dm−3 and for deep water intakes were 0.25, 0.24 and 0.20 mBq ...

Aging and Electrical Stability of DNTT Honey‐Gated OFETs
Advanced Electronic Materials, EarlyView.DNTT honey‐gated organic transistors were fabricated and evaluated to assess short‐ and long‐term stability under electrical stress and aging. Short‐term transfer measurements (five days, 40 sweeps/day) showed minimal parameter shift, while extended measurements revealed gradual degradation over weeks.

The Role of Certifications in Improving Household Food Security Among Peruvian Farmers
Agribusiness, EarlyView.ABSTRACT Achieving global food security requires sustainable transformations in agri‐food systems. Voluntary Sustainability Standards (VSS) such as Organic and Fairtrade aim to internalize certain social and environmental costs while promoting more equitable value distribution, improved market access, and sustainable production practices.

A route for polonium 210 production from alpha-particle irradiated bismuth-209 target [PDF]
, 2014 A method is proposed for production of polonium-210 via the 209Bi(α, 3n)210At nuclear reaction. Bombardment of a bismuth-209 target was performed with a 37 MeV alpha-particle beam that leads to the production of astatine-210 (T1/2 = 8.1 h), which decays ...

Advanced Intelligent Discovery, EarlyView.This study integrates random matrix theory (RMT) and principal component analysis (PCA) to improve the identification of correlated regions in HIV protein sequences for vaccine design. PCA validation enhances the reliability of RMT‐derived correlations, particularly in small‐sample, high‐dimensional datasets, enabling more accurate detection of ...
