Advancements in TLP Bonding for Power Electronics Die‐Attach Applications

Advanced Materials Technologies, EarlyView.
Transient Liquid Phase (TLP) bonding is gaining traction as a lead‐free die‐attach technology in power electronics packaging. This review examines the state of TLP bonding, its key elements, reliability aspects, and practical limitations. This review also highlights emerging trends, such as nanostructured interfaces, that may improve scalability of TLP

Efficient FORM-based extreme value prediction of nonlinear ship loads with an application of reduced-order model for coupled CFD and FEA

Journal of Marine Science and Technology, 2019
In this paper, a method for predicting the extreme value distribution of the vertical bending moment (VBM) in a ship under a given short-term sea state is presented. To predict the extreme value distribution of the VBM, the first-order reliability method

Full‐Domain 3D Digital Twin for Comprehensive Analysis and Validation of Standing Surface Acoustic Wave Generation on LiNbO3 Substrate

Advanced Materials Technologies, EarlyView.
A full‐domain 3D digital twin of a standing surface acoustic wave (SSAW) device on 128° YX LiNbO3 is developed and experimentally validated. The predictive power of the model is confirmed by electrical characterisation and laser Doppler vibrometry measurements, which show excellent agreement with simulations.

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel

Advanced Materials Technologies, EarlyView.
The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Determination of polar compounds by TLC-FID in refined and partially hidrogenated soja heated oils.

Grasas y Aceites, 1997
The thermal degradation of oils and fats leads to the formation of polar compounds, which is the reason why their determination is adopted for the quality control of the oil and fat used in frying.

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
