There is a limited number of metal alloys and metal-ceramic powders available for use in additive manufacturing (AM) processes. There is great demand to develop industrial-scale processes for producing raw material with ...

In this research, the effects of an Al2O3 nanoparticle additive on the structure and electrical properties of Pb0.88Sr0.12Zr0.54Ti0.44Sb0.02O3 (PSZST) ceramics were investi‐ gated. The PSZST ceramics with the addition ...

The results are presented of the study of kinetics of fragmentation of titanium nanofilms 100 nm thick deposited onto the surface of samples made from single crystals of Al2O3(leucosapphire), ZrO2, SiC, and AlN ceramics ...

Nanostructure CaCu 2.90 Zn 0.10 Ti 4 O 12 (CCZTO) electronic ceramic was synthesized by semi-wet route. The objective of this route is to enable the calcination and sintering processes to go for completion in shorter tim...

Two kinds of functionalized nanostructured hybrid microspheres, based on the bridged silsesquioxane family, were synthesized by employing the sol-gel method via self-assembly of two different organic-inorganic bridged mo...

The materials for medical application are normally consisted of metal, ceramic, and polymer. Each material has its own limitations such as corrosion in metal, the brittleness of ceramic, and the high temperature problem ...

This study presents a novel, modular 3D printing system for the scalable production of microbially induced calcium carbonate (CaCO3) precipitation (MICP) produced bio-materials. Through modular design principles and oper...

With a wide variety of post systems and materials available for the restoration of lost tooth structure of endodontically treated teeth, the clinical decision of which to use constitutes a challenge to dental practitione...

En este trabajo se presentan los resultados del análisis de la colección del Túmulo II del Brazo Largo (Delta Inferior del Paraná), datada en circa 750 años 14C AP. El registro arqueofaunístico se caracteriza por e...

In the past years, the consumption of energy produced by wind turbines had an exponential growth. This requirement gave momentum to the development of larger turbines with the goal of producing more energy at the same si...

The global transition to sustainable energy systems requires breakthroughs in electrochemical storage technologies that are not only safe but also resource efficient. Solid-state batteries (SSBs), which use superionic so...

Presentamos la caracterización tecnológica y composicional de cerámica de estilo Molinos hallada en la localidad de Punta de la Peña en Antofagasta de la Sierra (puna meridional argentina) y en sitios de la cuenca de...

Polymer composites of epoxy resin and Nb2O5 doped BaTiO3 were prepared in the form of film (thickness 30-300 μm) using a dipping technique. Samples containing various amounts of ceramic filler were examined by thermal a...

Exploramos las relaciones entre los habitantes indígenas de la llanura santiagueña y el estado Inca, a partir del análisis distribucional, contextual y estilístico de tres líneas de evidencias: artefactos metálicos...

This work presents, for the frst time, the development of magnetic composites using activated biochar (BC-Act) derived from yerba mate waste. It includes an analysis of the effect of the activation process on the formati...

The Tunas Formation crops out in the eastern sector of the Ventania System (southwestern Buenos Aires Province, Argentina) and represents the last unit of the Pillahuincó Group (Pennsylvanian–Cisuralian). This work in...

Using an exact solution for transient state population of a three-stage absorbing Markov chain the problem ofmodeling the bimodal behavior of three window materials represented as some self-repairing optical systemsprone...

La disponibilidad de recursos hídricos en Patagonia aparece como uno de los limitantes para la distribución de los seres vivos en el espacio. Es en ese contexto que, durante el Holoceno tardío, no sólo se destacan la...

Polyvinylidene fluoride (PVDF) is a semi-crystalline thermoplastic polymer renowned for its exceptional piezoelectric, pyroelectric, and ferroelectric properties, along with high chemical resistance, thermal stability, a...

Abstract Background This study aimed to evaluate the bond strength to dentin of dental posts fabricated with different PEEK using the push-out test, while also examining the failure modes. Methods Sixty mandibular premol...
