Extraction of Phytochemical Compounds from Eucheuma cottonii and Gracilaria sp using Supercritical CO2 Followed by Subcritical Water

open access: yesMATEC Web of Conferences, 2018
Extraction of phytochemical compounds (such as β-carotene, linoleic acids, carrageenan, and polyphenols) from algae Eucheuma cottonii and Gracilaria sp with supercritical CO2 followed by subcritical water has been investigated.

Subcritical water extraction of bioactive components from algae [PDF]

open access: yes, 2013
Subcritical water extraction (SWE) is presented in this chapter as a potent and novel alternative to conventional solvent extraction processes for isolating bioactive components from algae. SWE is defined as extraction with water at temperatures ranging from boiling point to the critical temperature and at pressures high enough to keep the water in a ...

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Subcritical water extraction laboratory plant design and application

open access: yesAnnual ... of the Croatian Academy of Engineering, 2017
Demand for different green extraction techniques, which provide shortened extraction time and reduced organic solvent consumption are in constant increase. Subcritical water is a green, cheap and non-toxic processing medium, which makes treatments inexpensive, ecofriendly, more selective and less time consuming.

Natural‐based antioxidants in cosmeceuticals: Extraction, bioavailability and skin ageing applications

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Natural antioxidants from plants, fruits, seeds and fungi combat ageing by neutralizing free radicals, boosting collagen and protecting against UV damage. Enhanced by green extraction and smart delivery systems, they offer powerful anti‐inflammatory and antimicrobial benefits.

Peri‐implant tissue definition and registration with a 3D‐printed emergence profile former on titanium stock healing abutment: A dental technique and clinical report

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Recent focus has shifted toward refining the soft tissue emergence profile to enhance aesthetics, support peri‐implant health, and ensure long‐term success. Traditionally, titanium stock healing abutments or chairside‐customized abutments were used to shape peri‐implant tissues and develop the emergence profile for implant‐supported prostheses.

Sleep Deprivation in Mice: Looking Beyond the Slow Wave Rebound

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep is a fundamental process supporting the dynamic regulation of neural function. Emerging methods have proposed that the aperiodic components of brain signals (such as the spectral slope, spectral intercept, and spectral knee), in addition to entropy‐based measures, offer robust empirical markers of neural states.

Variations in downslope activity and bottom current dynamics in a land‐detached submarine channel system since the Last Glacial Maximum

open access: yesSedimentology, EarlyView.
ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.
