Modification of Kalina cycle system 34g by replacing throttle valve with single-screw expander

Thermal Science, 2022
Recovery of the energy loss caused by throttling plays an important role in improving the performance of a cycle. Based on the original Kalina cycle system 34g, two redesigned cycles, which have different placement of single-screw expanders used to replace the throttle valve, are proposed in this paper.

Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

Advanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\
