Study on nonlinear phenomena in dual buck full-bridge inverter
Acta Physica Sinica, 2014 Dual buck full-bridge inverter has the following advantages: it has no shoot-through problem, but receives high-utilization of DC input voltage, high efficiency and optimum selection of the freewheeling diodes, hence it attracts more and more attention in high power applications.

Buck-boost converter Fed nine level cascaded H-bridge inverter [PDF]
This research investigates on simulation of a traditional cascaded H-bridge (CHB) five-level inverter and proposes a nine-level cascaded H-bridge inverter system. The performance of both five-level and nine-level inverter systems is evaluated by modeling

Transient Cytoskeletal Anisotropy Encodes Short‐Term Mechanical Memory in Glioblastoma Cells
Advanced Materials, EarlyView.The same mechanical deformation can produce distinct cytoskeletal states depending on loading history. Experiments and constitutive modeling reveal that transient actin–vimentin anisotropy stores mechanical information and governs short‐term mechanical memory in glioblastoma cells.

Chlorinated Byproducts in Diisocyanates Synthesis From 35Cl Nuclear Quadrupole Resonance
Helvetica Chimica Acta, EarlyView.We combine 35Cl NQR spectroscopy & DFT to identify trace chlorinated impurities in industrial MDI streams, creating a non‐destructive “analytical ruler” for chemical process monitoring. ABSTRACT Chlorinated impurities in industrial diisocyanates production significantly impact product quality and stability, yet their speciation remains an analytical ...
