Production of Bio-oil via Catalytic Pyrolysis of Medlar Seeds

open access: yesBioResources, 2023
The pyrolysis of medlar seeds was performed at 350, 450, 550, and 650 °C with and without K2CO3, MgO, and expanded perlite (10 wt%). The maximum dichloromethane extract yield (6.70 wt%) was obtained at 450 °C in the pyrolysis experiments without catalyst,

New sorbents for removal of petroleum-derived pollution on the basis of expanded perlite

open access: yesChemical and Process Engineering
New hydrophobic sorbents were developed to remove oil-derived pollutants. The process of hydrophobization was conducted by the application of stearic acid and the commercially available silicone agent Sarsil H.

The effect of expanded perlite on fired clay bricks

open access: yesJournal of Physics: Conference Series, 2020
Abstract Nowadays stricter energy regulations are compelling us to further improve the thermal insulation performance of current building materials. In this study we investigated the possibility of improving the thermal insulating performance of fired clay bricks.

The effect of moisture content on sound absorption of expanded perlite plates [PDF]

open access: yes, 2005
Expanded perlite is a porous, lightweight, fire resistant and moisture retaining material with sound and thermal insulation properties. In this research, acoustical behaviour of plates made of expanded perlite was studied experimentally.

A phosphatidic acid‐based retrograde signaling pathway responsive to abiotic stress in Arabidopsis

open access: yesThe Plant Journal, Volume 127, Issue 5, September 2026.
SUMMARY Due to their sessile nature, plants are constantly exposed to the environment and must cope with sometimes extreme changes in conditions during the day or growing season. Plants depend on photosynthesis as their primary means to generate energy and building blocks, and adverse environmental conditions can stress the photosynthetic apparatus ...

The Impact of Dextrin-Activated Expanded Perlite and Vermiculite Particles on the Performance of Thermal Insulating Rapeseed Oil-Based Polyurethane Foam Composites

open access: yesApplied Sciences
To enhance the performance of polyurethane foams, fillers are often incorporated into the matrix. However, the interaction between the filler and the polyurethane matrix is crucial for achieving the desired property improvements.

Advancements and Challenges in Liquid Hydrogen Storage Tank Design for Maritime Applications

open access: yesEnergy Storage, Volume 8, Issue 5, August 2026.
ABSTRACT In line with the Paris Agreement and the IMO's decarbonization goals, the shipping industry has begun to focus more intensively on adopting alternative fuels to reduce emissions. Among these, hydrogen has attracted considerable attention, with liquid hydrogen (LH2) offering advantages in energy density and storage volume over compressed gas ...

Study of the Biodegradation Properties of Amorphous Blends of Poly(Lactic Acid) and Poly(3‐Hydroxybutyrate‐co‐4‐Hydroxybutyrate) Foamed With Supercritical CO2

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Supercritical CO2 foaming of fully amorphous PLA/PHA blends produced low‐density closed‐cell foams with fine cellular morphology. Blending with PHA enhanced biodegradation under simulated home‐composting conditions, achieving up to 84% mass loss after 4 months, whereas marine degradation remained limited and was mainly restricted to the PHA component ...
