The Application of Supercritical Carbon Dioxide and Ethanol for the Extraction of Phenolic Compounds from Chokeberry Pomace

open access: yes, 2017
Chokeberry (Aronia melanocarpa (Michx.) Elliot) is a fruit with exceptionally high levels of phenolic compounds which are accumulated mainly in the peel; hence, the majority remains in the leftovers after juice production.

Manufacturing of PP‐Based Composite Sandwich Panels via Simultaneous Foaming and Skin‐Core Bonding

open access: yesPolymer Composites, EarlyView.
One‐step CO2 physical foaming process for manufacturing thermoplastic sandwich panels: in‐situ expansion of a foaming‐grade PP core and fusion bonding with PP/glass fiber composite skins. ABSTRACT Sandwich panels are skin‐core‐skin structures commonly used in aerospace applications due to their high strength‐to‐weight ratio and flexural stiffness.

Copolymer Synthesis of N‐Vinylacetamide and 2‐Methylene‐1,3‐Dioxepane Provides a New Degradable Polymer

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1306-1318, 15 March 2025.
ABSTRACT N‐vinylamides, especially noncyclic N‐vinylacetamide (NVA), have been used in various applications such as biomaterials, surfactants, and hydrogels. However, their potential to copolymerize with cyclic ketene acetal (CKA) to create degradable polymers is underexplored.

Method for growth of crystals by pressure reduction of supercritical or subcritical solution [PDF]

open access: yes, 1985
Crystals of high morphological quality are grown by dissolution of a substance to be grown into the crystal in a suitable solvent under high pressure, and by subsequent slow, time-controlled reduction of the pressure of the resulting solution. During the

3D Customized Silica‐Based AFM Probes Fabricated by Selective Laser Etching

open access: yesSmall Methods, EarlyView.
Selective laser etching (SLE) enables the monolithic fabrication of customized, fully 3D silica AFM probes integrating both cantilever and tip with controlled 3D geometries. The process allows the production of either sharp or spherical tips with high design flexibility, reproducibility, and yield.

Convective instability and mass transport of diffusion layers in a Hele-Shaw geometry

open access: yes, 2010
We consider experimentally the instability and mass transport of a porous-medium flow in a Hele-Shaw geometry. In an initially stable configuration, a lighter fluid (water) is located over a heavier fluid (propylene glycol).
