Artichoke Bracts and Stems Residues as Active Filler for Poly(Butylene Succinate‐Co‐Adipate) (PBSA) Composites: From Agro‐Waste to a New Sustainable Material

Polymer Composites, EarlyView.
PBSA‐based biocomposites made from artichoke bract and stem powders have been characterised and formulated for agricultural and food applications, such as active mulching films. ABSTRACT In the context of a growing bioeconomy and the drive for sustainable materials, new biocomposites were formulated by incorporating poly(butylene succinate‐co‐adipate) (

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.

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‐

Larvicidal Potential of the Halogenated Sesquiterpene (+)-Obtusol, Isolated from the Alga Laurencia dendroidea J. Agardh (Ceramiales: Rhodomelaceae), against the Dengue Vector Mosquito Aedes aegypti (Linnaeus) (Diptera: Culicidae)

Marine Drugs, 2016
Dengue is considered a serious public health problem in many tropical regions of the world including Brazil. At the moment, there is no viable alternative to reduce dengue infections other than controlling the insect vector, Aedes aegypti Linnaeus.
