Micellar and Solubilization Properties of Biological Surfactant Surfactin

open access: yesJournal of Surfactants and Detergents, EarlyView.
ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.

Optimization of Ethylbenzene Production Facility [PDF]

open access: yes
Ethylbenzene is a foundational organic compound used as a reactant in styrene production. The objective of this thesis is to present the optimization of the in-house production process of ethylbenzene, aiming to avoid external procurement for the ...

Ethylbenzene Disproportionation over Large Pore Zeolites

open access: yes, 1994
The disproportionation of ethylbenzene was studied over the large pore zeolite catalysts LaNaY, LaNaEMT, HL and HBeta, and over a zeolite with unknown pore structure, viz. HMCM-22.

A walk in the park—Identifying healthy greenspaces using scents

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
As urbanisation accelerates globally, access to nature is increasingly recognised as vital for public health and wellbeing. We captured and analysed plant‐emitted airborne ‘scent signatures’ across Oxford's urban greenspaces to assess their potential health relevance.

Detailed hazard assessment of ethylbenzene to establish an indoor air quality guideline in Japan

open access: yesEnvironmental Health and Preventive Medicine
Background: Indoor air quality (IAQ) is an important determinant of human health. In Japan, IAQ guidelines have been established for 13 chemicals since 1997.

Rhodium Cluster Catalysts Enable Efficient Catalytic Hydroformylation in Mild Conditions: Cluster Size Dependence

open access: yesSmall, EarlyView.
Nanometer‐sized Rh clusters provide a specific reaction environment that facilitates the balanced co‐adsorption of styrene, CO, and H, thereby promoting hydroformylation. ABSTRACT The size of the reactive metal domain, termed an ‘ensemble’, in supported metal catalysts critically influences their catalytic activity.

Mixed M-V-Sb oxides as oxodehydrogenization catalysts

open access: yesТонкие химические технологии, 2010
The properties of mixed M-V-Sb (M = Ni, Co, Bi, Sn) oxides, supported on aluminum oxide, have been physically characterized and their activities estimated .in dehydrogenation of light paraffins, ethyl benzene and ethanol.

Decoverslipping of Archival Cytology Aspirate Smears for Ancillary Studies: A Review of Methods and Institutional Experience With Freezer‐Based Techniques

open access: yesCytopathology, EarlyView.
Freezer‐based decoverslipping of archival cytology aspirate smears achieved only 32.5% slide‐level success (26/80), with mounting medium composition and coverslip material, not freezing temperature or duration, identified as dominant determinants, underscoring the need to align coverslipping practices with anticipated ancillary testing requirements ...

Optimization of Solid Phase Micro-Extraction (SPME) for Monitoring Occupational Exposure to Ethyl Benzene

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2009
Background and Objectives: Analytical methods for volatile organic compounds (VOCs) in different samples need extraction of compounds, by applying hazardous solvents. Solid phase micro-extraction (SPME) is a solvent-free equilibrium extraction method, in

Hypothesis-driven weight of evidence evaluation indicates ethylbenzene lacks endocrine disruption potential by EATS pathways

open access: yesEXCLI Journal : Experimental and Clinical Sciences
Ethylbenzene (EB) was placed on List 2 for Tier 1 endocrine screening in the U.S. EPA’s two-tiered Endocrine Disruptor Screening Program (EDSP) and was scheduled for evaluation under TSCA.
