Impact of initial gradation on compaction characteristics and particle crushing behavior of gravel under dynamic loading

open access: yes
Gravel is a widely used construction material due to its versatility and cost-effectiveness. However, gravel particles are prone to crushing under dynamic loading, causing changes in gradation.

Dissecting the dissection laboratory: Elements for designing a human anatomy laboratory

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The human anatomy dissection laboratory is a critical component of anatomical and medical education. Development, maintenance, and stocking of these laboratory spaces have unique demands, with all of the challenges in running a laboratory with Biosafety Laboratory Level 2 (BSL‐2) classification, housing a large volume of tissues saturated with

The Preprint Evolution: The Rise of Unreviewed Drafts on arXiv and Its Implications for Astronomy

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The arXiv preprint server originally democratized astronomical research by removing the financial barriers of journal subscriptions. However, a system designed for the lower publication volumes of the 1990s has fractured under modern research output. Today, the sheer volume of unreviewed manuscripts—often tagged as “submitted,” “under review,”

Characterizations of macroscopic deformation and particle crushing of crushed gangue particle material under cyclic loading: in solid backfilling coal mining

open access: yes, 2019
In solid backfilling coal mining (SBCM), the deformation resistance of crushed gangue particle material (CGPM) is critical for controlling overburden strata movement and ground surface subsidence.

A sustainable business ecosystem: a case study demonstrating biochar's potential

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The need for renewable, climate‐friendly resources has become urgent as legislators worldwide have sought to find ways to cut emissions while ensuring resource security for consumers. The use of biochar could help to achieve these goals. This study examines the current state of commercial biochar production and the maturity of the related ...

Biochar‐based fertilizers improve nutrient use efficiency in sunflower grown on a subtropical tidal soil

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Improving fertilizer use efficiency is essential for reducing environmental pollution, sustaining agricultural production, and maximizing the economic profitability of crop production systems. This study tested the hypothesis that the formulation strategy of biochar‐based fertilizers, rather than nutrient addition alone, is associated with ...

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

Biogas purification and enrichment: sustainability metrics analysis of dry anaerobic digester with cashew apple bagasse substrate

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study hypothesizes that cashew apple bagasse‐based anaerobic digestion, combined with biochar purification, enhances biogas quality and sustainability. This study aims to investigate the performance and sustainability of a biochar‐based biogas purification technology using cashew apple bagasse as a substrate, with a focus on environmental
