Passive harmonic filters in the ship's power system [PDF]

, 2020
U ovome radu obrađena je problematika upotreba harmoničkih filtra u brodskom elektroenergetskom sustavu. Na brodu se svi električni uređaji napajaju iz zajedničke centrale i što taj sustav čini posebno osjetljivim na harmonička izobličenja.

Tuning Mechanoreceptor Signaling Enhances the Adjuvant Effect of Biomaterial Vaccines

Advanced Functional Materials, EarlyView.
Matrix stiffness serves as an independent immunological signal in biomaterial vaccines. Stiffer microporous hydrogel vaccines enhance dendritic cell maturation and migration to draining lymph nodes, promote T follicular helper cell expansion through Yap/Taz signaling, and increase antigen‐specific antibody production.

Mechanically Mutable Matrices: A Hierarchical Investigation of Decellularized Sea Cucumber Collagen as an Adaptable Scaffold Material

Advanced Functional Materials, EarlyView.
Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...

Using special APF to improve harmonic rate of MRT power system

Journal of Low Frequency Noise, Vibration and Active Control
Most APFs use improved designs of active power filters of half-bridge and full-bridge circuits, their advantages and disadvantages are compared. International journals often use this filter circuit for small circuit boards.

Polarization Sensitivity of Chiral Manganese Halide Scintillators Enables High‐Resolution X‐Ray Imaging

Advanced Functional Materials, EarlyView.
Highly luminescent chiral manganese halide crystals are synthesized using chiral ligands, and they exhibit dissymmetry factors up to 1.4 × 10−2 and show X‐ray detection scintillation capability with a light yield of 43 380 photons/MeV and a low detection limit of 0.05198 µGyair·s−1.

Hybrid Power Filter Based on a Six-Switch Two-Leg Inverter

Eletrônica de Potência, 2014
Hybrid power filters (HPFs) are considered an attractive solution to overcome the problem of current harmonics generated by nonlinear loads. They mix low power rating active filters with passive filters, but many of these HPF topologies have a great ...

Charge Generation and Recombination Pathways in All‐Polymer Bulk Heterojunction Solar Cells

Advanced Functional Materials, EarlyView.
Multimodal spectroscopy and device analysis reveal how field‐dependent charge generation, transport limitations, and non‐geminate recombination govern performance losses in all polymer solar cells. The results identify the key processes controlling charge extraction and recombination, providing insights for the design of more efficient all‐polymer ...
