Statement Of Problem: Titanium has been considered the standard element in implant manufacturing. Recent studies have evaluated the role of titanium as a biological modulator of oral health. However, evidence regarding the association between the release of metal particles and peri-implantitis is lacking.
Purpose: The purpose of this scoping review was to evaluate the literature regarding the release of metal particles in peri-implant tissues correlated with the methods of detection and the local and systemic implications.
Material And Methods: The study was performed in adherence with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines and was registered with the National Institute for Health Research PROSPERO (Submission No. 275576; ID: CRD42021275576). A systematic search was conducted in the Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE via PubMed, Scopus, and Web of Science bibliographic databases, complemented by a manual evaluation. Only in vivo human studies written in the English language and published between January 2000 and June 2022 were included.
Results: In total, 10 studies were included according to eligibility criteria. Different tissues and analytic techniques were reported: the characterization technique most used was inductively coupled plasma mass spectrometry. All 10 studies analyzed the release of metal particles in patients with dental implants, continuously detecting titanium. None of the studies reported a significant association between metal particles and biological effects.
Conclusions: Titanium is still considered the material of choice in implant dentistry, despite the detection of metal particles in peri-implant tissues. Further studies are necessary to evaluate the association between analytes and local health or inflammatory status.

The recovery of valuable materials from spent lithium-ion batteries (LIBs) has experienced increasing demand in recent years. Current recycling technologies are typically energy-intensive and are often plagued by high operation costs, low processing efficiency, and environmental pollution concerns. In this study, an efficient and environmentally friendly dielectrophoresis (DEP)-based approach is proposed to separate the main components of "black mass" mixtures from LIBs, specifically lithium iron phosphate (LFP) and graphite, based on their polarizability differences.

Liquid metals are highly conductive like metallic materials and have excellent deformability due to their liquid state, making them rather promising for flexible and stretchable wearable sensors. However, patterning liquid metals on soft substrates has been a challenge due to high surface tension. In this paper, a new method is proposed to overcome the difficulties in fabricating liquid-state strain sensors.
View Article and Find Full Text PDFNative ion channels play key roles in biological systems, and engineered versions are widely used as chemogenetic tools and in sensing devices . Protein design has been harnessed to generate pore-containing transmembrane proteins, but the capability to design ion selectivity based on the interactions between ions and selectivity filter residues, a crucial feature of native ion channels , has been constrained by the lack of methods to place the metal-coordinating residues with atomic-level precision. Here we describe a bottom-up RFdiffusion-based approach to construct Ca channels from defined selectivity filter residue geometries, and use this approach to design symmetric oligomeric channels with Ca selectivity filters having different coordination numbers and different geometries at the entrance of a wide pore buttressed by multiple transmembrane helices.

The bi-transition-metal interstitial compounds (BTMICs) are promising for water electrolysis. The previous BTMICs are usually composed of irregular particles. Here, this work shows the synthesis of novel 1D CoMoC-based heterojunction nanowires (1D Co/CoMoC) with diameters about 50 nm and a length-to-diameter ratio about 20 for efficient water electrolysis.
