In this work, the characteristics of a commercial sample of LaNi5 are compared to those of an experimental one obtained by mechanical alloying followed by low temperature annealing. The nominal composition of the experim...

The braking system is a critical safety component in land vehicles, relying on efficient deceleration during operation. Among its elements, the brake disc plays a central role in dissipating the heat generated by frictio...

Abstract Photoinitiated polymerization of methyl methacrylate has been observed using cw-CO2 laser radiation of (10.6 µm). Both of DSC and TGA thermal analysis techniques were used for identification of the thermal char...

"Successful utilization of Additive Manufacturing (AM) in the space sector implicates two aspects: First, an understanding of the process inherent characteristics has to be developed, where the anisotropic behavior of ma...

In the present work, the mechanical performance of polylactic acid (PLA) based composites reinforced with hydroxyapatite (HA) or β-tricalcium phosphate (β-TCP) was investigated. The polymer was melt compounded with 1 a...

Phenolic mercapto oxadiazole and triazole monomers were prepared and then azotized with aniline and Para-phenylene diamine. The prepared monomers have been characterized with FTIR and1HNMR. The six prepared monomers were...

Pumice is a porous volcanic rock containing a significant proportion of silica and alumina, and which has a low iron content. This natural, silica-rich material attracts wide attention because of its applications in adso...

Abstract In this research, we prepared a eutectic ternary alloy from (Pb-Sn-Zn) metals under normal pressure. We investigated some of the physical properties of the alloy and their elements, which are thermal properties ...

"Church “Nuestra Señora de la Paz” is located in Pilar, province of Buenos Aires, Argentina. It has an octagonal floor plan and an internal volume of 2500 m3 with bare sidewalls and little ornamentation. Excessive r...

Abstract Molecular single-source precursors are a promising way of obtaining multi-element extended solids directly. We show that thermal decomposition of well-defined mono-, bi- and trimetallic polyoxovanadates (POVs) p...

"In this work, the peel of Arapey Sweet Potato (Ipomoea batatas), a vegetable waste, was used as a source of phenolic compounds which are widely recognized as beneficial antioxidants for human health. The extract obtaine...

Abstract This study aims to develop a performance grade (PG) zoning map for asphalt pavements along the Kabul–Salang Highway in Afghanistan, considering local climatic conditions and traffic factors, to support optimiz...

Abstract The differences in the proteolytic patterns and shear force of pork and beef during aging were evaluated. Pork and beef semitendinosus muscles were obtained at 24 and 48 h postmortem, respectively, and aged at 4...

Surface texturing consists of introducingwell-defined, intentional cavities on bearing surfaces, either on the housing or on the rotating shaft. Forsuch configurations, it iswell established in the literature that mass-c...

Metal oxides (MO) are essential in various industrial applications, yet their limited solubility in common solvents often hinders their utility. This study investigates the dissolution of Zinc Oxide (ZnO) using green a...

Although soil C is a critical component of soil health, studies robustly exploring the agronomic and pedoclimatic effects on soil C are limited, especially at the landscape scale. Therefore, a dataset of 1490 topsoil ...

En la provincia de Buenos Aires, cerca del 14% de las escuelas se encuentra en áreas rurales. Es frecuente que estas escuelas tengan que realizar ampliaciones en sus edificios que permitan absorber la creciente matrícu...

The main objective of the study is to improve energy efficiency of a shell-and-tube jet injection fer-menter (SJT) for aerobic cultivation of microorganisms. The relevance of the work is determined by the biotechnology i...

Waste materials from agricultural and food packaging usage pose significant health and environmental challenges, where the main source of waste originates from plastics and protein-based amino acids, and their thermal de...

Abstract This study examines the thermo- and photo-oxidative degradation of bio-based polyamide 5.10, both neat and reinforced with 20 wt% regenerated cellulose fibers (RCF). The materials were additionally modified with...

Abstract This model is highly helpful in thermal management and complex energy systems, particularly where precise control over heat and mass transfer is required. Solarized nanofluids can be used to improve heat absorpt...

Duplex stainless steels fabricated by Laser Bed Powder Fusion (LPBF) exhibit refined and metastable microstructures that can be particularly sensitive to intermediate-temperature exposure. In this study, the effect of 47...

Tertiary fatty amide, N,N-dibutyldodecanamide (DBDA), has been synthesized and evaluated as a new environmentally friendly plasticizer for polyvinyl chloride (PVC). Homogeneous PVC/DBDA films containing from 10 to 40 w...
