Densification of lightweight aluminum borate ceramics by direct sintering of milled powders

open access: yesJournal of Asian Ceramic Societies, 2018
Dense aluminum borate (Al18B4O33) materials were processed by simple milling-sintering of aluminum borate powders obtained by reacting calcined alumina and fine boric acid at temperatures of around 600–800ºC.

Danmarks Mineraler

open access: yesDanmarks Geologiske Undersøgelse II. Række, 1943
Den danske Mineralverden er, som man kan tænke sig, ikke særlig rig; Antallet af forskellige Mineraler er ikke stort (ca. 50), og der er ikke blandt Forekomsterne nogen, der udmærker sig ved store og smukke Krystaller, eller er videre iøjnefaldende paa anden Maade. Alligevel frembyder de dog forskelligt af Interesse, og jeg haaber, at en Sammenstilling

Frailty Predicts Incident Osteoporotic Fractures in Veterans with Rheumatoid Arthritis

open access: yesArthritis Care &Research, EarlyView.
Objective Rheumatoid arthritis (RA) is associated with an increased risk of frailty and osteoporosis, but the relationship between frailty and incident osteoporotic fractures in RA is underexplored. Methods Data were from the Veterans Affairs (VA) Rheumatoid Arthritis Registry. Frailty was measured using the VA Frailty Index (VAFI).

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

open access: yesAdvanced Engineering Materials, EarlyView.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an
