Rapid Communications in Mass Spectrometry, Volume 39, Issue 24, 30 December 2025.ABSTRACT Rationale The Japanese sea lion (Zalophus japonicus), once abundant in Japan, Korea, and Russia, went extinct by the mid‐20th century due to hunting and environmental change. This study examines the diet and ecological role of Korean Z. japonicus using stable carbon and nitrogen isotope analysis of bone collagen from archaeological and ...

Electrochemical preparation of tungsten, tungsten carbide and cemented tungsten carbide
Mineral Processing and Extractive Metallurgy, 2013Tungsten is conventionally made by the reduction of tungsten oxide with hydrogen, tungsten carbide by the reaction of tungsten with carbon and cemented tungsten carbide by the sintering together of tungsten carbide with a metal, usually cobalt. This paper reports the electrochemical preparation of tungsten, tungsten carbide and cemented tungsten ...

A review on cryogenic treatment of tungsten carbide (WC-Co) tool material
Materials and Manufacturing Processes, 2020Cryogenic treatment is a thermal treatment process in which the parts are usually cooled to temperatures below −70 C (< 203 K) to induce metallurgical changes in materials.

CEMENTED TUNGSTEN CARBIDE PNEUMOCONIOSIS
Acta Pathologica Japonica, 1978An autopsy case of cemented tungsten carbide pneumoconiosis, the first lethal case in our country, is presented. A 28‐year‐old woman, who had been engaged in grinding presintered metallic matrix for four years, developed respiratory symptoms. X‐ray examinations were indicative of interstitial pulmonary fibrosis.
