Study on the Influence Law of Asphalt Anti - Corrosion Coating Protection Efficiency Based on Performance Degradation [PDF]

open access: yesCailiao Baohu, 2022
In China, the sacrificial anode cathodic protection systems of many pipelines in service with asphalt coating have failed or are about to fail. If the sacrificial anode systems are replaced according to the original design, some pipelines could not be ...

Reducing graphene device variability with yttrium sacrificial layers [PDF]

open access: yesApplied Physics Letters, 2017
Graphene technology has made great strides since the material was isolated more than a decade ago. However, despite improvements in growth quality and numerous “hero” devices, challenges of uniformity remain, restricting the large-scale development of graphene-based technologies.

Epitaxial lift-off of II-VI semiconductors from III-V substrates using a MgS release layer [PDF]

open access: yes, 2013
Epitaxial lift-off (ELO) is a post-growth process that allows an epitaxial layer to be removed from its original substrate and transferred to a new one.

Embedded sacrificial layers for CMUT fabrication

open access: yes2015 IEEE SENSORS, 2015
Capacitive Micromachined Ultrasonic Transducers (CMUTs) are generally fabricated either by conventional sacrificial release process or by wafer bonding technique. In the former, sacrificial layers are patterned with deposited materials on the substrate.

Chromium oxide – A novel sacrificial layer material for MEMS/NEMS and micro/nanofluidic device fabrication

open access: yesMicro and Nano Engineering, 2022
Free standing membranes for fluidic devices typically require long etching times due to the slow, diffusion limited exchange of etchant and etch products when large etch distances are involved.
