Biosynthesis of Selenium Nanoparticles Supported on and within Diatomite through a Continuous Flow Method

Proceedings, 2020
Diatomite, also known as diatomaceous earth (DE), is a sedimentary rock formed by the deposition of shells of unicellular microscopic algae of the class Bacillariophyceae (diatoms). [...]

Navigating turbid waters: Effects of turbulence and suspended particulate matter on ingestion and defecation of the calanoid copepod Acartia tonsa

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract The interactive effects of turbulence and suspended particulate matter (SPM) on copepod feeding and egestion remain poorly understood. We experimentally examined how turbulence (0, 10−3, and 100 cm2 s−3) and SPM (0 and 150 mg L−1; Diatomaceous Earth), alone and combined, affect ingestion, fecal pellet production, gut passage time, assimilation

Effect of Foliar Application of Siliceous Nanomaterial on Photosynthesis Performance in Sweet Almond (Prunus dulci)

Proceedings, 2020
Siliceous natural nanomaterials, i.e., diatomaceous earth and natural zeolites, are biorational products, generally recognized as safe (GRAS) due to their large utilization as dietary supplement [1] and food/feed additive [2]. [...]

Hydrogen Production from Formic Acid and Methanol in a Fluidized Bed Made Out of Diatomaceous-Earth-Based Catalysts with Fast Chromatographic Hydrogen Detection

Energies
From the sedimentary rock moler, a specific fraction of diatomaceous earth suitable for fluidized-bed applications was isolated. Three heterogeneous catalysts were prepared by wet impregnation: Cu@diatomaceous-earth, Co3O4@diatomaceous-earth, and NiO ...

Effect of inert dust on the mortality of Sitophilus zeamais (Coleoptera: Curculionidae) [PDF]

Brazilian Journal of Biology
The maize weevil, Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae), generally reaches pest status in stored grain. Chemical control is the most used method for population suppression, which can cause adverse impacts, thus creating a need ...

Use of Diatomaceous Earth as a Silica Supplement on Potted Ornamentals

Horticulturae, 2019
The role of silica as a needed supplement in soilless media is gaining interest. This research studied the effects of diatomaceous earth as a supplement on growth and flower characteristics, physiology, and nutrient uptake in dahlia (Dahlia Cav.

Evaluating locally sourced inert dusts as insecticides against the cereal leaf beetle (Oulema melanopus [L.]; Coleoptera: Chrysomelidae): a combined laboratory and field study

Cogent Food & Agriculture
The Cereal Leaf Beetle (CLB), Oulema melanopus [L.], poses a major threat to wheat (Triticum aestivum L.) production, worsened by insecticide resistance and changing EU pesticide regulations.
