Chemoenzymatic Synthesis of Enantiopure Amino Alcohols from Simple Methyl Ketones

open access: yesEuropean Journal of Organic Chemistry, Volume 26, Issue 34, September 6, 2023., 2023
A site‐selective bromination, followed by a hydrolysis and an enantioselective biocatalytic synthesis yields valuable chiral amino alcohols (phenylglycinol derivatives) with excellent enantiomeric excesses. The presence of an extensive keto‐enol‐tautomerism even expands the range of amino alcohol products.

Soot formation in laminar counterflow flames [PDF]

open access: yesProgress in Energy and Combustion Science, 2019
Abstract Many practical soot-emitting combustion systems such as diesel and jet engines rely on diffusion flames for efficient and reliable operation. Efforts to mitigate soot emissions from these systems are dependent on fundamental understanding of the physicochemical pathways leading from fuel to soot in laminar diffusion flames.

Research and Development on Coatings and Paints for Geothermal Environments: A Review

open access: yesAdvanced Materials Technologies, Volume 8, Issue 18, September 25, 2023., 2023
Geothermal power production, by harnessing the natural heat in the earth's crust, provides clean energy, with year‐round availability. However, corrosion, erosion, and scaling of power plant components can hinder energy production. In his review paper, the first of its kind since 1980, a detailed overview of research studies on coatings developed to ...

Study on combustion performance of microgas turbine combustor with different fuels

open access: yesEnergy Science &Engineering, Volume 11, Issue 7, Page 2642-2653, July 2023., 2023
A low‐pollution single‐tube microgas turbine burner using different gas fuels is studied. The combustion performance and pollutant generation characteristics of two landfill gases and natural gas were tested in a single‐head burner. Abstract A low‐pollution single‐tube microgas turbine combustor using different gas fuels was studied.

A Numerical Study of CO2 Decoupled Effects on Extinction Limit and Flame Microstructure in CH4/Air Counterflow Diffusion Flame with Various Pressures

open access: yesInternational Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023
Extinction limits and flame microstructures of CH4 versus air (N2/O2) counterflow diffusion flames with additional CO2 to oxidizer stream under various pressure conditions were numerically investigated by a proposed decoupled strategy. The chemical and thermal effects of CO2 addition were isolated from the synergistic effect on extinction limits and ...

Influences of stretch and curvature on the temperature of stretched cylindrical diffusion flames

open access: yesJournal of Thermal Science and Technology, 2016
The structure of a counterflow-type cylindrical diffusion flame was studied experimentally to determine the effect of stretch and curvature. The cylindrical flame used in this study had a concave curvature with respect to the fuel stream.
