Аргументи „за” и „против” държавната намеса в аграрния сектор
Икономика и управление на селското стопанство, 2012 Целта на настоящата статия е да представи някои от основните аргументи в подкрепа или против субсидирането на аграрния сектор. Анализът ще изложи накратко ролята на държавното подпомагане за земеделието според икономическата теория.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations
Advanced Materials Interfaces, EarlyView.This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Advanced Materials Technologies, EarlyView.Polymer‐coated carbon nanotubes were engineered as protease‐responsive nanocarriers for protein delivery in intact plants. GFP cargo can be released by cytosolic phytaspase cleavage and subsequently targeted to mitochondria via an N‐terminal sequence, enabling controlled intracellular protein delivery without tissue damage and demonstrating stable ...

Advanced Materials Technologies, EarlyView.In this Perspective, we highlight the processing science and scale‐up capabilities of the Materials Engineering Research Facility (MERF) at the U.S. Department of Energy's Argonne National Laboratory, with an emphasis on practical solutions for sustainable water and critical resource recovery. We demonstrate how national laboratories bridge fundamental

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
