ZVZCS PWM Converter Using Secondary Active Clamp

open access: yesActa Electrotechnica et Informatica, 2011
A novel zero-voltage and zero-current switching (ZVZCS) pulse-width modulation (PWM) converter is presented in this paper. An active energy recovery clamp in the secondary side provides conditions for zero-current switching (ZCS) of the transistors in the primary side of the DC/DC converter.

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Common-Source Active Clamped Complex Type Converter

open access: yesIEEJ Transactions on Electronics, Information and Systems, 2007
This paper presents a novel common-source active clamped complex type converter. This converter is the intermediate isolated bus converter for the distributed power supply system in telecommunications equipment. Using active clamped circuits, the switching loss and switching noise can be reduced by means of the soft switching techniques.

Hydrocolloid‐Based Multiwavelength Stretchable QD‐OLED Patch for Simultaneous Neonatal Jaundice and Dermatitis Treatment with Biosignal Monitoring

open access: yesAdvanced Healthcare Materials, EarlyView.
Comparison of therapeutic and diagnostic applications of a surface‐emitting light source with multiwavelength emission characteristics. Abstract Conventional light‐emitting‐diode‐based light sources suffer from rigidity, localized heating, and poor adaptability to skin deformation, limiting their use in skin‐attached medical devices.

Information flow through a model of the C. elegans klinotaxis circuit

open access: yes, 2015
Understanding how information about external stimuli is transformed into behavior is one of the central goals of neuroscience. Here we characterize the information flow through a complete sensorimotor circuit: from stimulus, to sensory neurons, to ...

Plasma‐Polymerized Nanoparticles Presenting Fibrillin‐1 Drive Rapid Re‐Endothelialization of Vascular Grafts

open access: yesAdvanced Healthcare Materials, EarlyView.
Commercial vascular grafts are made from ePTFE, a highly hydrophobic, foreign material that fails at a high rate in small‐diameter applications. Plasma polymer nanoparticles (PPN) are a versatile material functionalisation tool, used here to present fibrillin‐1 fragment PF8 on the graft surface.
