Advancements and Challenges in Second‐ and Third‐Generation Biofuels: A Comparative Analysis of Lignocellulosic and Algal Feedstocks

open access: yesSafety Science and Technology, EarlyView.
ABSTRACT Advanced biofuels derived from nonfood biomass are increasingly recognized as strategic components of low‐carbon energy systems, particularly for sectors where direct electrification remains difficult. Second‐generation biofuels from lignocellulosic residues and third‐generation biofuels from algal and aquatic biomass offer complementary ...

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

open access: yesStructural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Exploring the potential of Textile Reinforced Concrete for corrosion‐insensitive retaining walls

open access: yesStructural Concrete, EarlyView.
Abstract In a context where durability concerns, particularly the corrosion of steel reinforcement, remain a critical challenge for conventional reinforced concrete structures under severe exposure, Textile Reinforced Concrete (TRC) is emerging as a promising alternative.

Bond, tension‐stiffening, and cracking in multi‐generational recycled aggregate concrete subjected to shrinkage strains

open access: yesStructural Concrete, EarlyView.
Abstract The concrete industry is responsible for a significant portion of global waste production and multi‐generation recycled aggregate concrete (MGRAC) is a means to allow the sector to transition to a circular economy framework. To predict the behavior of MGRAC at the member level there is a need to understand the underlying mechanics of bond ...

Biodiesel Production from Hevea brasiliensis Seeds: A Systematic Review

open access: yesVietnam Journal of Chemistry, EarlyView.
ABSTRACT The Hevea brasiliensis (HB) species, also called the rubber tree, is currently cultivated worldwide for the extraction of latex, an input for rubber production. In addition, its seeds currently have few productive applications, despite their high oil content.

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer

open access: yesWildlife Biology, EarlyView.
Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

open access: yesHigh Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

A Randomised Controlled Trial Comparing a One‐Piece Zirconia Tissue‐Level Implant and Two‐Piece Titanium Bone‐Level Implant for Maxillary Single Tooth Replacement—3 year Results

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives This RCT evaluated and compared the clinical performance of zirconia and titanium dental implants placed in the maxillary premolar region. Outcomes were assessed 3 years after prosthetic loading and included marginal bone level (MBL) changes, clinical parameters, aesthetic outcomes, and patient related outcome measures (PROMs ...

Effect of Implant Design on Fracture Resistance, Mode, and Crystal Structure of One‐ and Two‐Piece Zirconia Implants With Ceramic or Titanium Abutment Screws: An In Vitro Study

open access: yesClinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To evaluate the fracture resistance, fracture modes, and crystalline phase changes of zirconia one‐piece implants (OPI) and bone‐level (BLTPI) or tissue‐level, two‐piece implants (TLTPI), with ceramic (C) or titanium (T) abutment screws after dynamic preloading in a moist environment.
