Ablation resistance of certain epoxy compounds
Polymer Mechanics, 1972The rate of ablation in oxidative and inert media at flow velocities up to 200 m/sec has been investigated for certain epoxy compounds containing powdered copper and zinc dust. The causes of ablative destruction and the factors tending to improve the ablation resistance are examined.

Corrosion Science, 2020
Abstract Si-Mo alloy was infiltrated into porous graphite to develop a short-term low-ablative SiMo/graphite composite material. 19.4 vol.% residual Si was retained in the composites and significantly improved the short-term (less than 60 s) ablation resistance without sacrificing long-term (∼180 s) ablation resistance.

Revision on Renal Sympathetic Ablation in the Treatment of Resistant Hypertension
Current Hypertension Reviews, 2016Hypertension is one of the most prevalent diseases in the world, with about 1 billion people affected and a possible increase to 1.5 billion by 2025. Despite advances in treatment, a proportion of patients remain resistant to conventional treatment and uncontrolled, and this can adversely affect future cardiovascular events and mortality. This alarming

Polymer resist materials for excimer ablation lithography
Applied Surface Science, 1998Abstract Excimer ablation lithography (EAL) is a new lithography suitable to TFT-LCD. Among the constituent technologies, the polymer materials for the resist is most crucial, as high ablation rates are required at low fluence. To elucidate the ablation mechanism at low fluence we specified some characteristic features through observations of about ...

Advances in the ablation resistance of C/C composites
Carbon, 2015Carbon/carbon (C/C) composites are considered the most promising materials for high-temperature structural applications owing to their excellent properties at high temperature. However, oxidation and ablation limits their applications in oxygen-containing environments at ultrahigh temperatures and high-speed gas flows.

ATF7 ablation prevents diet-induced obesity and insulin resistance
Biochemical and Biophysical Research Communications, 2016The activating transcription factor (ATF)2 family of transcription factors regulates a variety of metabolic processes, including adipogenesis and adaptive thermogenesis. ATF7 is a member of the ATF2 family, and mediates epigenetic changes induced by environmental stresses, such as social isolation and pathogen infection.

Laser Ablation of Etch Resists for Structuring and Lift-Off Processes
2009Structuring of dielectric and metal layers as well as silicon itself are key processes in the production of silicon solar cells. In this paper we suggest selective structuring of etch resist and organic lacquers by laser ablation as a general structuring approach. This approach is a simple and fast way of creating small structures in an etch resists or
