Analysis of Temperature and Stress Distribution on the Bond Properties of Hybrid Tailored Formed Components

open access: yesAdvanced Engineering Materials, EarlyView.
Hybrid materials enable high‐performance components but are challenging to process. This study explores an inductive heating concept with spray cooling for steel–aluminum specimens in a two‐step process including friction welding and cup backward extrusion.

Precursor proteins in transit through mitochondrial contact sites interact with hsp70 in the matrix [PDF]

open access: yes, 1990
We previously reported that hsp70 in the mitochondrial matrix (mt-hsp70 = Ssc1p) is required for import of precursor proteins destined for the matrix or intermembrane space.

The Impact of the Pandemic on International Trade in the Republic of Moldova

open access: yesACROSS, 2022
The article analyses the impact of isolation measures applied both nationally and internationally on reducing external demand from the main partners of the Republic of Moldova (Moldova), which has caused and resulted in declining exports, economic ...

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

open access: yesAdvanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Mitochondrial import receptors for precursor proteins [PDF]

open access: yes, 1991
The specific targeting of precursor proteins synthesized in the cytosol to various cell organelles is a central aspect of intracellular protein traffic. Several hundred different proteins are imported from the cytosol into the mitochondria.

An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave
