Double Contour Thermodynamic Cycle with Unidirectional Heat Transfer between the Refrigeration and the Energy Cycle [PDF]

Problems of the Regional Energetics, 2019
Practical characteristics of the method for improving cycles of complex cooling thermotrans-formers associated with the regeneration of the refrigeration cycle heat productivity (RCHP) are considered. The use of heat from the working fluid compression in

Bio‐Friendly Artificial Muscles Based on Carbon Nanotube Yarns and Eutectogel Derivatives

Advanced Functional Materials, EarlyView.
Solid‐state artificial muscles based on coiled commercial carbon nanotube yarns coated with eutectogel derivatives exhibit unipolar actuation through selective ion intercalation. Combining polyanionic and polycationic gels enables enhanced contractile stroke and high energy density.

Preliminary prospects of a Carnot-battery based on a supercritical CO2 Brayton cycle

Acta Polytechnica, 2021
As a part of the change towards a higher usage of renewable energy sources, which naturally deliver the energy intermittently, the need for energy storage systems is increasing. For the compensation of the disturbance in power production due to inter-day

Encoding Magnetic Anisotropies in Digital Light Processing 3D Printing

Advanced Functional Materials, EarlyView.
A hybrid magnetic device—combining a coaxial coil within a nested Halbach array—is presented, integrated into a DLP 3D printer to enable spatially resolved magnetic field control. This system enables complex, multimodal responses by programming liquid crystal elastomer resins for magnetic and thermal actuation, and by inducing electrically conductive ...

Harnessing Colloidal Dispersion for Laccase‐Driven Enzymatic Depolymerization of Polystyrene

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Polystyrene (PS), long considered non‐degradable by biocatalytic pathways, can now be broken down under aqueous conditions using atmospheric air and a laccase–mediator system composed of a commercially available fungal enzyme and 1‐hydroxybenzotriazole as small organic mediator.
