The contact resistance performance of gold coated carbon-nanotube surfaces under low current switching [PDF]

open access: yes, 2013
Multi-Walled CNT (MWCNT) are synthesized on a silicon wafer and sputter coated with a gold film. The planar surfaces are mounted on the tip of a piezo-electric actuator and mated with a gold coated hemispherical surface to form an electrical contact ...

Operating Lifetime Behavior of Thermal Contact Resistance Between Clip-Attached TO 247 Package and Heat Sink with and Without an Ultra-Thin Interlayer Silver Film

open access: yesEnergies
The thermal contact resistance between a clip-attached TO 247 package and heat sink is a very large contributor to the total thermal resistance. Therefore, it is important to investigate its reliability and lifetime behavior.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

A comparison of the predictions of a finite element model and multiscale model for a rough MEMS electrical contact

open access: yes, 2013
Rough surface contact is difficult to model effectively due to multiple scales of detail that need to be considered. This work presents the results of a multiscale rough surface contact model in comparison to a finite element based deterministic model ...

Thermal and arc erosion behavior of CuCr contact material based on large plastic deformation treatment

open access: yesJournal of Materials Research and Technology, 2023
CuCr alloys are the main contact materials used in medium-voltage and high-current vacuum interrupters. In this paper, the effect of large plastic deformation on microstructure and the transverse/longitudinal thermal conductivity of CuCr30 contact ...

The Numerical Estimation of Thermal Contact Resistance in Contacting Surfaces [PDF]

open access: yesAmerican Journal of Applied Sciences, 2008
For some manufacturing processes, the heat transfer between the components, the tools and the environment has an effect on tool-life and the accuracy of the formed component. Consequently, the measurement of Thermal Contact Resistance (TCR) is of increasing interest to researchers and industrial engineers participating in the manufacture of high ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Contact-Resistance-Free Stretchable Strain Sensors with High Repeatability and Linearity

open access: yes, 2021
Most of the existing stretchable strain sensors are based on the contact-resistance mechanism, where the stretchability and resistance variation depend on the change of the contact relationship of the conductive microstructures.

Simulation of contact thermal resistance when designing processing equipment

open access: yesFrontier Materials & Technologies, 2023
Analysis of the processing equipment structures when designing according to the temperature criterion is a necessary guarantee of ensuring the required performance characteristics. The presence of a significant number of parts in the processing equipment

CEACAM1 participation in breast cancer progression

open access: yesMolecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.
