Modeling of the formation of short-chain acids in propane flames [PDF]

open access: yesarXiv, 2009
In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), acetic (CH3COOH), propionic (C2H5COOH) and propenic (C2H3COOH)) acids, has been developed. Simulations of lean (equivalence ratios from 0.9 to 0.48) laminar premixed flames of

Discovery Of Copper Catalyst For New Chemical Polishing Acid On Superconducting Niobium [PDF]

open access: yesarXiv, 2020
High field Q-slope (HFQS) seriously limits the high gradient performance of the buffered chemically polished (BCP) superconducting radio frequency (SRF) niobium cavities. The direct cause or mechanism is not yet fully understood. In our recent extensive data analysis, we concluded that the potential root cause could be nitrogen contamination on the ...

A thermodynamic basis for prebiotic amino acid synthesis and the nature of the first genetic code [PDF]

open access: yes, 2009
Of the twenty amino acids used in proteins, ten were formed in Miller's atmospheric discharge experiments. The two other major proposed sources of prebiotic amino acid synthesis include formation in hydrothermal vents and delivery to Earth via meteorites.

The evidence for α-linolenic acid and cardiovascular disease benefits: Comparisons with eicosapentaenoic acid and docosahexaenoic acid.

open access: yesAdvances in Nutrition, 2014
Our understanding of the cardiovascular disease (CVD) benefits of α-linolenic acid (ALA, 18:3n-3) has advanced markedly during the past decade. It is now evident that ALA benefits CVD risk.

Eicosapentaenoic Acid Protects against Palmitic Acid-Induced Endothelial Dysfunction via Activation of the AMPK/eNOS Pathway

open access: yesInternational Journal of Molecular Sciences, 2014
Recent studies have shown that free fatty acids are associated with chronic inflammation, which may be involved in vascular injury. The intake of eicosapentaenoic acid (EPA) can decrease cardiovascular disease risks, but the protective mechanisms of EPA ...

Angiogenesis as a Therapeutic Target of (Poly)phenols: Tackling Cancer and Vascular‐Related Complications

open access: yesMolecular Nutrition &Food Research, EarlyView.
(Poly)phenols constitute a source of natural therapeutic molecules capable of targeting angiogenesis in different scenarios. This review summarizes the current evidence of the role of (poly)phenols in modulating angiogenesis. The reader can find a compilation of preclinical and human investigations describing pro‐ and anti‐angiogenic effects of these ...
