Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

The Impact of “Soft Power” Means on the Hybridization of Modern Wars

Metafizika Journal
Modern wars are experiencing a period of serious transformation. The dominance of “hard power” inherent in classical wars has come to an end. This is due to the increased influence of non-military threats on global security. In this case, the increasing role of information, economic, demographic, cultural, political, financial and other factors, along ...

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

What is Power Sharing? Its Meaning and Three Types: Consociationalism, Centripetalism, and Hybrid Power Sharing

Studia Polityczne, 2018
In this article the author analyzes the term “power sharing” (PS) in the context of power exercised within a state. He first examines the term in the very general sense, in which it can be applied to all types and dimensions of power sharing between various groups and institutional entities.
