Optimization of softwood pretreatment by microwave-assisted deep eutectic solvents at high solids loading.

open access: yesBioresource Technology, 2022
Microwave-assisted deep eutectic solvent (DES) has received attention as an ultrafast pretreatment method in lignocellulose fractionation. This study investigated the improvement of milled softwood mixture (MSM) fractionation with chlorine chloride ...

Overcoming extended lag phase on optically pure lactic acid production from pretreated softwood solids

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Optically pure lactic acid (LA) is needed in PLA (poly-lactic acid) production to build a crystalline structure with a higher melting point of the biopolymer than that of the racemic mixture.

Full Scale Evaluation of GFRP Confined Softwood after Long-Term Exposure to High Humidity Environment [PDF]

open access: yes, 2023
Plantation softwood timber poles are associated with low natural durability, and it is also not clear what the effects of the high humidity environment on the long-term performance of composite action integrity of such a system.

One-step peracetic acid pretreatment of hardwood and softwood biomass for platform chemicals production

open access: yesScientific Reports, 2021
Lignocellulosic biomass is an attractive renewable resource to produce biofuel or platform chemicals. Efficient and cost-effective conversion systems of lignocellulosic biomass depend on their appropriate pretreatment processes.

Mechanical properties of the most common European woods: a literature review

open access: yesFracture and Structural Integrity, 2020
Wood is an orthotropic material used since ancient time. A literature research about the mechanical properties of density, fracture toughness, modulus of elasticity, and Poisson s ratio has been done to have a broader view on the subject.

Role of IAA and Primary Metabolites in Two Rounds of Adventitious Root Formation in Softwood Cuttings of Camellia sinensis (L.)

open access: yesAgronomy, 2022
The type of adventitious root formation of tea softwood cuttings is different from that of single node cuttings. In addition to the callus at the base of cuttings, the adventitious roots are also formed in the upper cortex of softwood cuttings.
