Fluoride release of orthodontic cements before and after recharge with fluoride solution

, 2008
Objetivo: O objetivo deste estudo foi comparar a liberação de flúor de cimentos de ionômero de vidro (CIV) utilizados para cimentação ortodôntica, antes e após recarga de flúor. Metodologia: Foram avaliados três CIV: Meron (VOCO), Vidrion C (SS WHITE) e Ketac-Cem (3M ESPE). A liberação de flúor foi medida através de eletrodo íon seletivo conectado a um

Near‐Theoretical Redox‐Site Utilization and Fast Zn2+ Storage in a Polyimide‐CNT Cathode

Small, EarlyView.
A CNT‐integrated PTO‐based π‐conjugated polyimide cathode achieves near‐theoretical redox‐site utilization, ultrafast Zn2+ storage up to 20 A g−1, and exceptional cycling stability over 10 000 cycles in aqueous zinc‐ion batteries. ABSTRACT Achieving high utilization efficiency together with fast electrochemical transport remains a central challenge for

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Redistributing Cobalt and Tungsten From WC–Co Soft Scrap Toward Sustainable Cathode and Coating Materials for Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
A sustainable upcycling strategy transforms tungsten carbide–cobalt (WC–Co) soft scrap into high‐performance cathode materials. Recycled Co with trace nickel (Ni) is resynthesized into stabilized LiCoO2 with superior high‐voltage durability, while the recovered tungsten is further utilized as tungsten trioxide to enhance Ni‐rich cathode interfaces ...
