Double‐VISTA technique with connective tissue graft or acellular dermal matrix for treating multiple recessions associated with non‐carious cervical lesions: A retrospective study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This retrospective study evaluated whether clinical outcomes differed between connective tissue graft (CTG) and allogeneic solvent‐dehydrated acellular dermal matrix (ADM) for treating multiple gingival recessions associated with non‐carious cervical lesions (NCCLs) using partial restoration and the double‐vestibular incision ...

Characterization and Preliminary Investigation of Alkylpolyglucoside Combined With a Biopolymer for Enhanced Oil Recovery

open access: yesJournal of Surfactants and Detergents, EarlyView.
Materials and main results of the study. ABSTRACT Surfactant–polymer (SP) flooding is a promising Enhanced Oil Recovery (EOR) technique, combining improved displacement from surfactants with enhanced sweep efficiency from polymers. This study investigates two SP systems based on the biopolymer scleroxanthan (a blend of sclerotium gum and xanthan gum ...

Styrene and its natural analogues: accumulation and sustainable production methods

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Styrene, also known as vinyl benzene, is a colourless, highly volatile petrochemical that serves as a key monomer in the production of polystyrene and styrene‐butadiene rubber. Its industrial synthesis via the alkylation of benzene with ethylene relies on fossil fuels, requiring high temperatures and toxic catalysts that contribute to ...

Innovations in polysaccharide‐based hydrogels in sustainable agriculture

open access: yesPolymer International, EarlyView.
Polysaccharide‐based hydrogels are promising in sustainable agriculture, as these natural polymers have the ability to absorb water and nutrients and release them gradually in the soil, in addition to ensuring biodegradability and lower cost. However, some challenges still need to be overcome.

Viscoelastic Modeling of Stress Relaxation in Model High‐Performance Covalent Adaptable Networks

open access: yesJournal of Polymer Science, EarlyView.
Covalent adaptable networks, often referred to as vitrimers, contain a certain fraction of bonds that are able to exchange with other bonds. The ability of this bond exchange to relax stress or result in flow of the material depends on the concentration and specific concentration of these bonds in ways that can be quantified.
