The chromian marbles of Kittilä, Finnish Lapland [PDF]
Bulletin of the Geological Society of Finland, 1978 The volcano-sedimentary rock association at Kittilä is characterized in many places by the presence of green-colored fuchsite-bearing ferroan dolomite-quartz rocks, locally called chromian marbles.

Microplastics from Wearable Bioelectronic Devices: Sources, Risks, and Sustainable Solutions
Advanced Functional Materials, EarlyView.Bioelectronic devices (e.g., e‐skins) heavily rely on polymers that at the end of their life cycle will generate microplastics. For research, a holistic approach to viewing the full impact of such devices cannot be overlooked. The potential for devices as sources for microplastics is raised, with mitigation strategies surrounding polysaccharide and ...

Colloidal Crack Sintering Lithography for Light‐Induced Patterning of Particle Assemblies
Advanced Functional Materials, EarlyView.Colloidal crack sintering lithography (CCSL) is a microfabrication technique that uses light‐induced photothermal heating to trigger sintering and controlled cracking in polymer colloidal assemblies. Local structural changes generate microchannels and patterns, enabling direct writing of diverse topographic motifs.

Sediment-Hosted Copper Mineralization in Bavanat Region, Southern Sanandaj-Sirjan, Iran [PDF]
Journal of Sciences, Islamic Republic of Iran, 2019 Sedimentary Copper mineralization has been observed in Monj and Jolany locations in Bavanat (Sanandaj – Sirjan metamorphic belt). According to current study, the host rocks for copper mineralization in this area are green sandstones, generally in ...

Modeling the growth of stylolites in sedimentary rocks [PDF]
, 2012 [1] Stylolites are ubiquitous pressure solution seams found in sedimentary rocks. Their morphology is shown to follow two self-affine regimes. Analyzing the scaling properties of their height over their average direction shows that (1) at small scale ...

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications
Advanced Functional Materials, EarlyView.Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...
