Novel Low‐Temperature Operating Catalytic Combustion‐Type Methane Gas Sensor Based on Gadolinium Silicate‐Supported Palladium Oxide

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
In this study, a novel catalytic combustion‐type methane gas sensor was developed using an 11.3 wt.% PdO/20 wt.% Gd10Si6O27/γ‐Al2O3 (PdO/GdSiO/AlO) catalyst. The incorporation of GdSiO as a promoter efficiently supplied active oxygen species to the PdO, thereby enabling methane combustion at low temperatures.

Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

VIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Characterisation and textural analysis of Middle Bronze Age Transdanubian inlaid wares of the Encrusted Pottery Culture, Hungary: a preliminary study

, 2008
Inlaid ceramics belonging to the Encrusted Pottery Culture and dated to the Middle Bronze Age (2000–1500 BC) are highly distinctive vessels with complex decorative motifs found in large numbers in the Transdanubia region of Hungary.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Chemical Stability and Bond Strength of Endodontic Sealers Exposed to Acidic, Alkaline and Protein‐Rich Environments: An In Vitro Investigation

Australian Endodontic Journal, EarlyView.
ABSTRACT The sealing performance of endodontic sealers may be influenced by environmental factors such as pH and blood‐derived proteins. This in vitro study evaluated the effects of pH variation and protein contamination on calcium ion (Ca2+) release and push‐out bond strength (BS) of a calcium silicate‐based sealer (Bio‐C Sealer) and an epoxy resin ...

Influence of Drying Protocol on the Setting and Crystalline Phase Formation of Calcium Silicate‐Based Sealers

Australian Endodontic Journal, EarlyView.
ABSTRACT The objective of this study was to assess the hydration, crystalline structure, and setting of bioceramic ready‐to‐use and powder/liquid sealers in dry and wet root canal dentine. Thirty‐two single‐rooted human teeth were embedded in acrylic resin and sectioned into 2‐mm segments.

Strontium coupling with sulphur in mouse bone apatites

Reviews on Advanced Materials Science
One of the key aspects of new advanced biomaterial development is to understand and design new compositions of selected components. The important idea for bioapatite-based materials is the substitution of Ca by other elements, such as strontium. Here, we
