Effect of Triton-x-100 on the Rate of Hydrogen Evolution at a Cathode

International Journal of Electrochemical Science, 2014
The effect of H2 evolution on the mass-transfer coefficient of cathode reduction of potassium ferricyanide at a mercury cathode was studied with the aim of (i) comparing the mass transfer behavior at a Hg cathode with that at solid electrodes under gas ...

Velocity and temperature distributions in compressible turbulent boundary layers with heat and mass transfer [PDF]

, 2000
In the present work, asymptotic methods are used to derive new expressions for the law of the wall, for the law of the wake and for the skin-friction and the Stanton number equations, for compressible turbulent boundary layers with heat and mass transfer.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Uma análise do coeficiente de remoção de poluentes em função do espectro de gotas de chuva em diferentes localidades no Brasil e Alemanha An analysis of pollutant scavenging coefficient in function of drop size distributions from different localities in Germany and Brazil

Química Nova, 2010
The pollutant transference among reservoirs atmosphere-hydrosphere, relevant to the atmospheric chemistry, depends upon scavenging coefficient (Λ) calculus, which depends on the raindrop size distribution as well as on the rainfall systems, both ...

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Study on Boiling Heat Transfer Characteristics of R290 in Horizontal Micro-tubes

Zhileng xuebao, 2020
In this study the boiling heat transfer characteristics of R290 in a 1, 2, and 4 mm horizontal micro-tube were investigated experimentally. The effects of mass flow rate [50-600 kg/(m2?s)], quality (0-1), and heat flux (5-20 kW/m2) on the boiling heat ...

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells

FEBS Open Bio, EarlyView.
Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

Bubble mass transfer in fluids under gravity: a review of theoretical models and intensification technologies in industry

Frontiers in Physics
Bubble mass transfer is a common phenomenon in industrial applications. In this paper, bubble dynamics in both still and turbulent flow were introduced first, followed by the mass transfer properties of a single bubble and bubble swarms.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

FEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.
