Eco‐Friendly Surfactants From Pithecellobium dulce: Extraction, Characterization and Surface Activity

Journal of Surfactants and Detergents, EarlyView.
Schematic representation of the comprehensive analysis of saponins extracted form of Pithecellobium dulce (Roxb.) Benth. ABSTRACT The widespread use of synthetic surfactants in industrial and domestic applications has raised environmental concerns due to their biodegradability and ecological issues.

Elemental composition and oxidation of chamber organic aerosol [PDF]

, 2011
Recently, graphical representations of aerosol mass spectrometer (AMS) spectra and elemental composition have been developed to explain the oxidative and aging processes of secondary organic aerosol (SOA).

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

On the implications of aerosol liquid water and phase separation for modeled organic aerosol mass [PDF]

, 2016
Water is an important component of PM2.5 Many traditional SOA species are highly soluble and thus can be considered extractable Water can influence the partitioning of compounds traditionally considered insoluble in models Organic aerosol takes up water ...

Seasonal measurements of total OH reactivity fluxes, total ozone loss rates and missing emissions from Norway spruce in 2011 [Discussion paper] [PDF]

, 2012
Numerous reactive volatile organic compounds (VOCs) are emitted into the atmosphere by vegetation. Most biogenic VOCs are highly reactive towards the atmosphere's most important oxidant, the hydroxyl (OH) radical.

Harnessing Phytochemicals for Brain Cancer Therapy: Insights Into Medulloblastoma and Glioblastoma Treatment

Phytochemical Analysis, EarlyView.
ABSTRACT Primary brain tumors are life‐threatening diseases. Glioblastoma is the most aggressive type with a poor prognosis. Medulloblastoma is the most common pediatric brain tumor. While surgical treatments often result in recurrences owing to the complex nature of the tumor microenvironment, conventional treatments lower the quality of life of ...

Influence of crosslinker on the properties of terpene‐based poly(high internal phase emulsion)s

Polymer International, EarlyView.
Myrcene was polymerized and crosslinked with hydrophilic monomeric and oligomeric dimethacrylates within high internal phase emulsions to produce hierarchically porous bio‐based poly(high internal phase emulsion)s with tuned morphology and mechanical properties.

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

Polymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐
