Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

Advanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on

Radiation attenuation properties of yttrium lithium borate glasses

Journal of Radiation Research and Applied Sciences
As the glass is used in a variety of fields, it is vital to test it on radiation shielding purposes. In this article, the radiation attenuation properties of examined glasses by replacing Li2O for Y2O3 have been investigated.

Melting and Rippling Phenomenan in Two Dimensional Crystals with localized bonding

, 2010
We calculate Root Mean Square (RMS) deviations from equilibrium for atoms in a two dimensional crystal with local (e.g. covalent) bonding between close neighbors. Large scale Monte Carlo calculations are in good agreement with analytical results obtained

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Comparison of radiation shielding properties of some coordination polymers

Radiation Protection and Environment, 2019
We have studied the X-ray and gamma radiation shielding parameters such as mass attenuation coefficient, linear attenuation coefficient, mean free path, half-value layer, tenth-value layer, effective atomic numbers, electron density, exposure buildup ...

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

Advanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

A superburst from 4U 1254-690

, 2003
We report the detection with the BeppoSAX Wide Field Cameras of a superburst from 4U 1254-690. The superburst is preceded by a normal type-I X-ray burst, has a decay time that is the longest of all eight superbursts detected so far and a peak luminosity ...

New Directions in Focused Ion Beam Induced Deposition for the Nanoprinting of Functional 3D Heterostructures

Advanced Materials Technologies, EarlyView.
Here, it is shown that focused ion beam induced deposition (FIBID) using helium and neon ions enables advanced high‐resolution 3D nanoprinting achieving precise multimaterial architectures and engineered internal voids. Thus, FIBID with finely focused noble gas ion species is presented as a unique platform for designing functional nanomaterials for ...
