Opinion: Gavage Administration of MXene as a Route‐Specific Alternative to Intravenous Injection into the Bloodstream of Laboratory Animals for Reducing Systemic Nanotoxicity Risks in Immunosuppression and Post‐Transplantation Models with Bile Acid Modification

Advanced Healthcare Materials, EarlyView.
Recent studies reported immunosuppressive properties of specific MXene nanomaterials. Their intravenous injection into the bloodstream of laboratory animals has been a common delivery method to suppress systemic inflammation and prevent transplant rejection.

Time-domain analysis methods for switching convertors

1988., IEEE International Symposium on Circuits and Systems, 2003
Two algorithms are presented for a time-domain analysis of a switching convertor which is replaceable with a piecewise-linear system. One of these algorithms is for the transient state analysis and the other is for the steady-state analysis. Both algorithms use eigenvalue and eigenvector calculations of the matrix.

Saturable reactor assisted soft-switching full-bridge DC-DC power convertors

IEE Proceedings B Electric Power Applications, 1991
A new soft-switching converter technique is introduced which employs small saturable reactors and phase-shift modulation. This considerably reduces switching losses with no substantial increase in conduction losses. The proposed soft-switching concept and its modifications to full-bridge DC-DC power convertors are shown and discussed.

Family of saturable reactor assisted soft-switching PWM DC—DC convertors

IEE Proceedings B Electric Power Applications, 1992
A family of improved soft-switching pulse width modulation DC-DC convertors employing a saturable reactor assisted soft-switching technique are presented. These convertors use a small saturable reactor(s) to achieve efficient soft switching, and have advantages such as low switching and low conduction losses, wide load range and constant frequency ...

Step-up/down voltage PWM AC to DC convertor with one switching device

IEE Proceedings B Electric Power Applications, 1993
A new PWM AC-DC convertor with only one switching device is proposed. The control of the AC-DC convertor based on the PWM strategy to make the source current in phase with the source voltage is described, and a simple and practical input filter design is proposed.

Code Convertor-Binary to Uniform Minimal Switching Representation (UMSR)

2021 5th International Conference on Trends in Electronics and Informatics (ICOEI), 2021
The low-power arithmetic design has become a very important aspect for recent compact electronic gadgets. The need to minimize dynamic power dissipation is vital for combinational circuits. Switching activity is a vital reason for the dissipation of power in combinational circuits, which includes activities like spurious pulses, called glitches ...

Modified switched power convertor with zero ripple

Proceedings of the 32nd Midwest Symposium on Circuits and Systems, 2003
A modified power conversion scheme suitable for switched mode converters which addresses the problem of output ripple without incurring an appreciable loss of efficiency is presented. An analog controlled current source is used to inject a current into the load which is equal and opposite to the ripple current due to the switching circuit.

Giant Orbital-to-Spin Conversion for Efficient Current-Induced Magnetization Switching of Ferrimagnetic Insulator.

Nano letters (Print), 2023
It has long been believed that the attachment of two heavy metals such as Ta and Pt with opposite spin Hall angles results in a weakened net torque generation efficiency in magnetization switching devices.

Power convertor circuits for switched reluctance motors with the minimum number of switches

IEE Proceedings B Electric Power Applications, 1990
The phase windings of a doubly salient switched reluctance motor are fed with unipolar pulses of current from a suitable power convertor to control the speed and torque of the motor. A new range of power convertor circuits for the switched reluctance motor is proposed in this paper.
