Studies on the Analysis of Surface Active Agents. X VI.

open access: yesJournal of Japan Oil Chemists' Society, 1960
For the analysis of aromatic surfactants by ultraviolet spectrophotometry, the absorption spectra of various surfactants, i.e., sodium dodecylbenzene sulfonate, alkyl pyridinium halides, alkyl benzyl dimethyl ammonium chlorides, POE alkyl phenols and formaldehyde condensates of naphthalene sulfonate, have been measured.

SENSOR ARRAY ABLE TO DETECT AND RECOGNISE CHEMICAL WARFARE AGENTS [PDF]

open access: yes
In this paper we studied a device based on array of six different sensors with surface acoustic wave for detections and recognition of three chemical warfare agents (chloropicrin, soman and lewisite).

Spatial biology in cancer epigenetics

open access: yesMolecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Voltammetric Behavior and Determination of Isoniazid Using PEDOT Electrode in Presence Of Surface Active Agents

open access: yesInternational Journal of Electrochemical Science, 2011
An electrochemical sensor was developed by using poly(3,4-ethylenedioxy thiophene) electrode in presence of different types of surfactants. Voltammetric behavior of isoniazid was studied at this electrode in the presence and absence of SDS and CTAB and ...

Microbial surface tensio-active compounds: Production and industrial application perspectives: A review [PDF]

open access: yes, 2017
Biosurfactants are surface active agents produced naturally by a wide variety of microorganisms, which include different strains of bacteria, fungi and yeast. Biosurfactants, also known as microbial surfactants, are amphiphilic compounds.

ADP‐ribosylation: An emerging regulator of the epigenome

open access: yesMolecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Application of secondary of polymers and surface active agents to increase heavy oil recovery [PDF]

open access: yesActa Montanistica Slovaca, 2006
Basin on a comparison of laboratory results with results obtained by screening modelling, one of the most promising methods was selected – the method of oil displacement by means of the polymer injection.Water intended for the injection is thickened with

Enhancement of mechanical and electrical properties of continuous-fiber-reinforced epoxy composites with stacked graphene

open access: yesBeilstein Journal of Nanotechnology, 2017
Impregnation of expandable graphite (EG) after thermal treatment with an epoxy resin containing surface-active agents (SAAs) enhanced the intercalation of epoxy monomer between EG layers and led to further exfoliation of the graphite, resulting in stacks

Synthesis and Properties of Surface Active Agents. I.

open access: yesJournal of Japan Oil Chemists' Society, 1962
The “Pickling” of steel or iron comprises removal of metal oxide on the surface by immersion in an acid. It has been found that the addition of cationic surface active agents (CSA) which have been called “Inhibitor” to acid decreases the rate of corrosion.In order to study the relationship between chemical construction of CSA and corrosion inhibitive ...
