22. A study of scarless wound healing through programmed inflammation, proliferation and maturation using a redox balancing nanogel.

Author

Das, Monojit, Mondal, Susmita, Ghosh, Ria, Darbar, Soumendra, Roy, Lopamudra, Das, Anjan Kumar, Pal, Debasish, Bhattacharya, Siddhartha Sankar, Mallick, Asim Kumar, Kundu, Jayanta Kumar, and Pal, Samir Kumar

Abstract

In the study, we have shown the efficacy of an indigenously developed redox balancing chitosan gel with impregnated citrate capped Mn3O4 nanoparticles (nanogel). Application of the nanogel on a wound of preclinical mice model shows role of various signaling molecules and growth factors, and involvement of reactive oxygen species (ROS) at every stage, namely hemostasis, inflammation, and proliferation leading to complete maturation for the scarless wound healing. While in vitro characterization of nanogel using SEM, EDAX, and optical spectroscopy reveals pH regulated redox buffering capacity, in vivo preclinical studies on Swiss albino involving IL‐12, IFN‐γ, and α‐SMA signaling molecules and detailed histopathological investigation and angiogenesis on every stage elucidate role of redox buffering for the complete wound healing process.

23. Development of Space Charge Limited Electron Gun Employing Virtual Cathode Position Simulation.

Abstract

The design and development of the electron gun for vacuum electronic devices is a critical and challenging task having a profound impact on device performance. Current state-of-the-art electron gun simulation codes employ the concept of a virtual cathode for the simulation of space charge-limited electron guns, where the virtual cathode distance is to be provided as an input by the user. In this report, an approach to calculate the virtual cathode position through analytical formulation and simulation is presented. The effect of inaccurate virtual cathode on gun parameters is studied through simulation and its repercussions are explained. The approach has been applied in the simulation using three-dimensional tracking solver to design a 50 kV, 10 Amp electron gun, which is to be used in a C-band Klystron. Based on the design, a Gun-Collector-Test-Module (GCTM) has been developed and hot-tested for experimental validation. A good agreement between the simulated and measurement results validates the design approach of the electron gun. [ABSTRACT FROM AUTHOR]

Abstract

A compact and high gain dual semi-circular slotted patch antenna with moderate bandwidth for 60 GHz applications is presented in this article. A rectangular-shaped patch inspires this design. The slotted antenna provides an impedance bandwidth of 1.75 GHz (58.87–60.62 GHz) and a gain of 7.55 dB. The overall size of the proposed antenna is 12 × 9.5 mm2. A dielectric superstrate is used to improve the antenna bandwidth and gain. The proposed antenna with superstrate exhibits an improved bandwidth of 2.48 GHz (58.22–60.70 GHz), an enhanced gain of 11.8 dB, and an efficiency of 95%, respectively. The antenna provides stable time-domain performance (isolation, isolation phase, group delay, and fidelity factor) over the operating band. The design prototype is fabricated and tested experimentally. Measured results exhibit a good agreement with the simulated results. The proposed antenna is suitable for high data-rate radio access and high gain 60 GHz applications. [ABSTRACT FROM AUTHOR]
