A comprehensive review of the application of cold plasma technology in lignocellulosic biomass pretreatment

open access: yesBiofuels, Bioproducts and Biorefining, Volume 19, Issue 2, Page 453-468, March/April 2025.
Abstract Lignocellulosic biomass (LCB) is a promising feedstock for the sustainable production of biofuels and other biobased products, owing to its abundance, low cost, and minimal competition with food crops for resources. It is mainly composed of cellulose, hemicellulose, and lignin, forming a complex biomass matrix.

Role of tidal range and coastline morphology on the evolution of two macrotidal sand spits

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 311-327, February 2025.
Based on historical map and stratigraphic data, the construction dynamics of two sandspits, respectively, subject to macrotidal and hypertidal range (6.5 m vs. 14 m), and that both appeared at the end of the 17th century, are compared. The hypertidal spit developed fast, between 1650 and 1750 CE, with a dominant seaward direction while the macrotidal ...

Present‐Day Shortening Accommodated by Folding, Thrusting and Strike‐Slip Faulting in the Enriquillo Basin of Southern Central Hispaniola: Implications for the Regional Seismic Hazard

open access: yesTectonics, Volume 44, Issue 1, January 2025.
Abstract Hispaniola accommodates a significant portion of the present‐day convergence between Caribbean and North American plates. Located in southern Hispaniola, the Neogene Enriquillo basin is bounded by the Neiba and Bahoruco mountain ranges. The role of active individual faults and fault systems in this basin is not well understood, particularly ...
