Parallel processing techniques in EMP propagation using 3D Finite-Difference Time-Domain (FDTD) method [PDF]

Advances in Engineering Software, 1993
The authors have applied the 3D FDTD technique to simulate the propagation of electrical signals on a microstrip antenna using a four-transputer array connected to a 386-based PC. This relates to work currently being carried out into the propagation of very high speed digital pulse in printed circuit boards in high bandwidth systems.

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

Advanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Finite difference time domain (FDTD) method for modeling the effect of switched gradients on the human body in MRI [PDF]

Magnetic Resonance in Medicine, 2002
AbstractNumerical modeling of the eddy currents induced in the human body by the pulsed field gradients in MRI presents a difficult computational problem. It requires an efficient and accurate computational method for high spatial resolution analyses with a relatively low input frequency.

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

Advanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Fast and accurate determination of 3D temperature distribution using fraction-step semi-implicit method

AIP Advances, 2016
In this paper, we proposed a method to numerically determinate 3-dimensional thermal response due to electromagnetic exposure quickly and accurately. Due to the stability criterion the explicit finite-difference time-domain (FDTD) method works fast only ...

Programmable Stepwise Heteroepitaxial Growth of Colloidal Crystals With Different Phases

Advanced Materials, EarlyView.
Stepwise heteroepitaxial growth is adapted to colloidal crystal engineering with DNA, enabling face‐centered cubic (fcc) facets to grow on body‐centered cubic (bcc) crystals with 110 facets. This approach tolerates large lattice mismatches, extending heteroepitaxy beyond the limits of conventional atomic systems.
