SrRThe natural occurrence of elements such as aluminium and silicon in their native form is usually ascribed to either contamination or the presence of strongly reducing fluids 1 (for example, pure methane or hydrogen, although such fluids have never been found in nature). Here we describe the formation of crystals of native aluminium, silicon, titanium, iron and platinum inside the quartz tubes that we used to sample hot volcanic gas jets associated with Kudriavy volcano on lturup island in… 
Vanadium, V – a new native element mineral from the Colima volcano, State of Colima, Mexico, and implications for fumarole gas composition
Abstract Vanadium, V, is a new mineral found in sublimates of high-temperature fumaroles of the Colima volcano, Mexico. The mineral precipitates over a narrow temperature range of 550-680°C, and
Native aluminum: Does it exist?
Several papers reporting exotic native elements have been published within the last few decades. The “native” occurrences described are rather dubious in view of the lack of solid proof of their

Gold transport during magmatic degassing: Model experiments
Interaction of metallic gold with (Na, K)Cl salt melts was investigated by the weight-loss method at 700–1000°C using silica glass ampoules. Interaction was not detected in hermetic evacuated
Discovery of native aluminum on Variscan metagranitoids in Upper Carinthia, Austria: natural or anthropogenic origin?
Native aluminum was discovered in 2004 at Hochwurten, Goldberg mountain group, Upper Carinthia, Austria. The discovery site is close to the Wurtenkees (glacier), where the dominant rock (Central
The nature and formation of cristobalite at the Soufrière Hills volcano, Montserrat: implications for the petrology and stability of silicic lava domes
Cristobalite is commonly found in the dome lava of silicic volcanoes but is not a primary magmatic phase; its presence indicates that the composition and micro-structure of dome lavas evolve during,
From dome to disease : the respiratory toxicity of volcanic cristobalite
Exposure to fine-grained volcanic ash can potentially cause acute and chronic respiratory disease. The toxicity of ash is likely to vary depending on the type and style of eruption; eruptions at
The first finding of native platinum in Cretaceous-Paleogene boundary clay, the gams section, Eastern Alps, Austria
For the first time, native platinum was found by microprobe analysis in the course of detailed studies of a transitional clay bed in the Cretaceous-Paleogene boundary, the Gams section, Eastern Alps,
Plant-derived silica nanoparticles and composites for biosensors, bioimaging, drug delivery and supercapacitors: a review
TLDR
To fight the COVID-19 pandemic, recent research has shown that silver nanocluster/silica deposited on a mask reduces SARS-Cov-2 infectivity to zero, and properties, preparation and applications of silica nanoparticles are reviewed.

KUDRIAVY volcano on Iturup island in the Kuril arc is an active calc-alkaline volcano. It has not erupted this century; its current volcanic activity is characterized by hot (up to 910oC) gas jets
