Wireless In Situ Catalytic Electron Signaling‐Mediated Transcriptomic Reprogramming for Neuron Regeneration via Adaptable Antennas

open access: yesAdvanced Science, EarlyView.
A wireless‐charging sustained oxygen release from conductive microgels (SOCO) served as an antenna and an on‐demand O2 release for nerve regeneration is developed. Introducing “electromagnetic messenger”, using external alternating magnetic field (AMF) to enhance catalytic oxygen release and electrical stimulation to promote the reconstruction of blood

Newmark-FDTD Formulation for Modified Lorentz Dispersive Medium and Its Equivalence to Auxiliary Differential Equation-FDTD with Bilinear Transformation

open access: yesInternational Journal of Antennas and Propagation, 2019
The finite-difference time-domain (FDTD) method has been popularly utilized to analyze the electromagnetic (EM) wave propagation in dispersive media. Various dispersion models were introduced to consider the frequency-dependent permittivity, including ...

Similarity Transformations of the Lorentz Transformation

open access: yes, 2014
We supplement the Lorentz transform $L(v)$ with a new "Tunneling" transform $T(v)$. Application of this new transform to elementary quantum mechanics offers a novel, intuitive insight into the nature of quantum tunneling; in particular, the so called "Klein Paradox" is discussed.

Magnetic Field‐Driven Catalysis: Revealing Enhanced Oxygen Reactions in Li‐O2 Batteries Using Tailored Magnetic Nanocatalysts

open access: yesAdvanced Science, EarlyView.
A series of Mn‐Co‐Fe oxides with different saturated magnetization (Ms) are prepared to evaluate the enhancement catalytic properties of magnetic catalysts on Li‐O2 batteries (LOBs). A deep understanding of the intricate relationship between the magnetism of electrocatalysts and the corresponding performance of LOBs under the influence of magnetic ...

Thermal Control of Vortex Motion in Nanoscale Superconductors

open access: yesAdvanced Electronic Materials, EarlyView.
Vortices in superconducting film can be thermally steered by a local heating from a tip. The work shows that the vortex is attracted by the hot spot by a force that emulates an electric field resulting in a fictious Lorentz‐force on the vortex. Abstract Thermally induced motion of vortices in nanoscale superconductors (SCs) is investigated.

Lithium extraction from salt‐lake brines using dicationic ionic liquids: ePC‐SAFT modeling and molecular mechanisms

open access: yesAIChE Journal, EarlyView.
Abstract This work proposes a novel strategy for enhancing Li+ extraction from salt‐lake brines with the high Mg2+/Li+ ratio using dicationic ionic liquid (DIL)‐based extractants. The ternary mixture of the DIL [DOMIM][Tf2N]2, tributyl phosphate (TBP), and dichloromethane (DCM) as a diluent achieved a higher single‐stage Li+ extraction efficiency (86 ...

Theory of Complex Gravitation

open access: yesReports in Advances of Physical Sciences
Here, we present a new physical quantity with the aim of unifying the structure of physics. The basic assumption starts with a reduction of all the natural forces into a single force.
