Investigation of Tribological Performances for Porous Structure of Diatom Frustule with FSI Method

open access: yesAdvances in Condensed Matter Physics, 2014
Tribological performances of the diatom frustule are investigated with the liquid-solid interaction (FSI) method. Take, for example, the representative Coscinodiscus sp.

Towards a representative periphytic diatom sample [PDF]

open access: yesHydrology and Earth System Sciences, 2007
The need to acquire a representative periphytic diatom sample for river water quality monitoring has been recognised in the development of existing diatom indices, important in the development and employment of diatom monitoring tools for the Water ...

Diatom-Specific Oligosaccharide and Polysaccharide Structures Help to Unravel Biosynthetic Capabilities in Diatoms

open access: yesMarine Drugs, 2015
Diatoms are marine organisms that represent one of the most important sources of biomass in the ocean, accounting for about 40% of marine primary production, and in the biosphere, contributing up to 20% of global CO2 fixation.

Use of benthic diatom indices for assessing ecological status of the Sai Gon river, Vietnam

open access: yesVietnam Journal of Science, Technology and Engineering, 2018
In the present study, the Biological diatom index (BDI) and the Trophic diatom index (TDI) were calculated for the assessment the ecological status and the water quality of the Sai Gon river in comparison with the physico-chemical variables. In addition,

Identification coral reef diatom using scanning electron microscope at Nature Reserve Pulau Sempu (NRPS), East Java

open access: yesDepik Jurnal
Diatom, Bacillariophyceae, has an important role in environmental support because these algae contribute to 25% of the oxygen supply globally and each year represent 40% of primary production by fixed carbon using photosynthesis.

Technical note: Nitric acid addition reduces residues and increases diatom-detection efficiency in the diatom testing of closed organs

open access: yesForensic Science International: Reports
We aimed to assess the ability of a revised diatom testing method, namely nitric acid addition (NAAdd), where nitric acid is added after the first digestion, to reduce residue content and maintain diatom-detection efficiency, in two experiments (1 and 2)

Biochemical characterization of Fucoxanthin Chlorophyll a/c binding proteins in the diatom Phaeodactylum tricornutum [PDF]

open access: yes, 2012
Diatoms contribute largely to the total primary production of the ecosphere and are key players in global biogeochemical cycles. Their chloroplasts are surrounded by four membranes owing to their secondary endosymbiotic origin.
