Cavity resonator for dielectric measurements of high-ε, low loss materials, demonstrated with barium strontium zirconium titanate ceramics.

Numai utilizatorii înregistrați pot traduce articole

A resonant cavity method is presented which can measure loss tangents and dielectric constants for materials with dielectric constant from 150 to 10 000 and above. This practical and accurate technique is demonstrated by measuring barium strontium zirconium titanate bulk ferroelectric ceramic

Tuning the cavities of zirconium-based MIL-140 frameworks to modulate CO2 adsorption.

Numai utilizatorii înregistrați pot traduce articole

A combined experimental and computational study has revealed the interplay between the framework pore size and functionality on the CO2 adsorption performance of zirconium-based MIL-140 frameworks. The CO2-sorbent interactions were markedly influenced by pore-confinement effects which arise from the

Shaping Solid-State Supramolecular Cavities: Chemically Induced Accordionlike Movement of gamma-Zirconium Phosphate Containing Polyethylenoxide Pillars.

Numai utilizatorii înregistrați pot traduce articole

The hydrophilic oxygen atoms of polyethylenoxide chains inserted as pillars in gamma-zirconium phosphate form hydrogen bonds with the acid groups of the host. As a result the pillars are almost perpendicular to the gamma layers. Upon changing the pH level of the supernatant solution the hydrogen

Fracture resistance of endodontically treated mandibular first molars with conservative access cavity and different restorative techniques: An in vitro study.

Numai utilizatorii înregistrați pot traduce articole

The aim was to investigate in vitro the fracture resistance (FR) of endodontically treated teeth (ETT) with conservative access cavity restored using various direct and indirect restorative materials and techniques. Seventy-two mandibular first molars were equally divided into six groups. Teeth in

A zirconium metal-organic framework with an exceptionally high volumetric surface area.

A zirconium metal-organic framework (MOF), PCN-111, has been synthesized by using an elongated ditopic carboxylate linker, 4,4'-(buta-1,3-diyne-1,4-diyl)dibenzoate. Single crystal X-ray diffraction characterization indicates that the noninterpenetrated microporous structure of PCN-111 is

Microprobe and SEM analysis of surface coatings on caries-like lesions in enamel after metal ion mordanting and APF application.

Numai utilizatorii înregistrați pot traduce articole

The production of tenacious surface coatings on enamel after metal ion mordanting followed by APF has been reported to prevent caries-like lesion initiation in vitro. In this study, similar surface coatings, which may be responsible for the inhibition of lesion progression, were examined using SEM

Diagnosis of external root resorption in teeth close and distant to zirconium implants: influence of acquisition parameters and artefacts produced during cone beam computed tomography.
