Improved enzymatic activity by oriented immobilization on graphene oxide with tunable surface heterogeneity

open access: yes, 2021
The precision design of surface properties of supports and immobilization methodologies is essential for improving the biocatalytic activity of immobilized enzymes. In this study, we proposed a surface heterogeneity regulation strategy of graphene oxide (

The surface magnetic activity of the weak-line T Tauri stars TWA 7 and TWA 25 [PDF]

open access: yes, 2021
International audienceABSTRACT We present an analysis of spectropolarimetric observations of the low-mass weak-line T Tauri stars TWA 25 and TWA 7. The large-scale surface magnetic fields have been reconstructed for both stars using the technique of ...

Activity of surface active substances determined from their surface excess [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2005
Commonly, the surface excess is determined from surface tension measurements via the Gibbs equation. This equation relates the activity (chemical potential), the surface excess, and the surface tension. When knowing two out of the three quantities, the third one can be calculated.

SPERMICIDAL ACTIVITY OF SURFACE-ACTIVE AGENTS [PDF]

open access: yesReproduction, 1962
Summary. The spermicidal activities against human spermatozoa of a range of non-ionic, anionic and cationic surface-active agents have been determined with the method of Baker, Ransom & Tynen (1937). Although it has been concluded that surface-tension-lowering properties do not directly influence spermicidal ...

Palmitoylcarnitine, a surface‐active metabolite [PDF]

open access: yesFEBS Letters, 1996
Palmitoylcarnitine is a well‐known intermediate in mitochondrial fatty acid oxidation. Less known are its properties as a surfactant, with a capacity to solubilize biological membranes similar to that of many synthetic detergents used in the biochemical laboratory.

The role of surface stoichiometry in the activity of doped vanadia-based catalysts for the selective catalytic reduction [PDF]

open access: yes, 2022
Mixing dopants into oxide catalysts can improve the catalytic activity, as shown in the dramatic boost of the NH3 selective catalytic reduction (SCR) activity on vanadia catalysts upon doping by tungsten.

Synthesis and evaluation of ?-hydroxy fatty acid-derived heterocyclic compounds with potential industrial interest

open access: yesGrasas y Aceites, 2007
The reaction of 2-hydroxyheptadecanoyl chloride (2) and anthranilic acid gave 2-(1-hydroxyheptadecyl)-4H-3,1-benzoxazin-4-one (3) which was used as starting material to synthesize some condensed and non-condensed heterocyclic compounds by a reaction with
