Microstructure of Ba1−xLaxTiO3−δ ceramics sintered by spark plasma sintering [PDF]

, 2011
Nano-sized Ba1−xLaxTiO3 (0.00 ≤ x ≤ 0.14) powders were prepared by a coprecipitation method and calcined at 850 °C in air. The corresponding ceramics were obtained by Spark Plasma Sintering (SPS) at 1050 °C.

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

Advanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Silicate Biomaterials‐Induced Bone Marrow Organoids for Tissue Regeneration

Interdisciplinary Materials
The bone marrow is essential for immune function, hematopoiesis, and skeletal system. The emergence of bone marrow organoids (BMOs) holds promise for addressing bone‐related deficiencies, although maintaining BMOs homeostasis is still challenging, and ...

An Inkjet‐Printed Platinum‐Based Temperature Sensing Element on Polyimide Substrates

Advanced Engineering Materials, EarlyView.
An inkjet‐printed, meander‐structured, nanoparticle platinum‐based resistive temperature sensors on polyimide substrates are demonstrated as proof‐of‐concept. Optimized sintering at 250°C enables stable conductive structures. The Pt100‐ and Pt1000‐type sensors exhibit linear resistance–temperature characteristics with stable TCR in the 20°C–80°C range,

Anode interfacial layer formation via reductive ethyl detaching of organic iodide in lithium–oxygen batteries

Nature Communications, 2019
To fulfill the great promise of Li-O2 batteries, the high charge overpotential is a major challenge that has to be addressed. Here the authors introduce triethylsulfonium iodide as a redox mediator as well as an enabler of a protective layer on Li anode,

Enabling Digital Continuity in Virtual Manufacturing for Eco‐Efficiency Assessment of Lightweight Structures by Means of a Domain‐Specific Structural Mechanics Language: Requirements, Idea and Proof of Concept

Advanced Engineering Materials, EarlyView.
This article presents a solver‐agnostic domain‐specific language (DSL) for computational structural mechanics that strengthens interoperability in virtual product development. Using a hierarchical data model, the DSL enables seamless exchange between diverse simulation tools and numerical methods.

Optimizing the properties of vat photopolymerization 3D-printed SiC ceramics by multi-infiltration

Journal of Asian Ceramic Societies
Digital Light Processing (DLP) technology is a highly effective molding method for creating complex structural parts. However, the low solid content of SiC stereolithography slurry has been found to diminish the mechanical properties of the ceramic ...

Fundamental tribological properties of ceramics [PDF]

When a ceramic is brought into contact with itself, another ceramic, or a metal, strong bond forces can develop between the materials. Adhesion between a ceramic and itself or another solid are discussed from a theoretical consideration of the nature of ...
