Вісник Харківського національного університету імені В.Н. Каразіна: Серія Екологія, 2019 Purpose. We attempted to quantify the contribution of wild-growing mycelium of ectomycorrhizal fungi to the soil level of selected metals and non-metals in upper (0−10 cm) layer of forest soil of boreal forest ecosystems.

A Perspective on the Metal-Nonmetal Transition
, 1999 Publisher Summary This chapter discusses a model that was proposed 30 years ago deceptive in its simplicity and laid the foundations for much of the science underlying the metal–nonmetal transition. The apparent simplicity of the problem—to transform a metal into a nonmetal or insulator, and vice versa—belies the subtlety and complexity of this, the ...

Spectrophotometric determination of plutonium with chlorophosphonazo III in n-pentanol [PDF]
, 1982 Microgram amounts of plutonium are measured spectrophotometrically as the plutonium-chlorophosphonazo III complex after extraction into n-pentanol from 1.5 M HCl. The relative standard deviation is 1.5% for the range of 2.5 to 17.5 ..mu..g. The tolerance

Predicting the Band Gaps of Inorganic Solids by Machine Learning
, 2018 A machine-learning model is developed that can accurately predict the band gap of inorganic solids based only on composition. This method uses support vector classification to first separate metals from nonmetals, followed by quantitatively predicting ...

Sliding Ferroelectricity Driven Spin‐Layertronics in Altermagnetic Multilayers
Advanced Science, EarlyView.Integrating sliding ferroelectricity with altermagnetism enables nonvolatile electrical control of spin and layer degrees of freedom. In bilayer CuF2, interlayer translation reverses layer‐locked spin‐split bands, establishing a multifunctional “spin‐layertronic” platform.

Learning Work Function via Implicit Reasoning on Electrostatic Potential Landscapes
Advanced Science, EarlyView.StructPot‐CLR establishes a cross‐modal contrastive learning framework that aligns the crystal structures of 2D materials with plane‐averaged electrostatic potential landscapes for physically informed work‐function prediction. The model achieves an MAE of 0.265 eV and an R2 of 0.902 on the held‐out test set while accurately preserving key morphological

Engineering Polar Nanoregions in COFs via Controlled Symmetry Breaking Toward Piezocatalysis
Angewandte Chemie, EarlyView.Polar nanoregions (PNRs) are engineered within covalent organic frameworks via asymmetric grafting of highly polar polyfluoroalkyl chains, which enables controlled symmetry breaking. These randomly oriented artificial PNRs dynamically respond to mechanical stimuli and impart relaxation behavior to the COFs (TFB‐TAPT‐FA).
