Long-range three-body atom-diatom potential for doublet Li${}_3$

open access: yes, 2012
An accurate long-range {\em ab initio} potential energy surface has been calculated for the ground state ${}^2A'$ lithium trimer in the frozen diatom approximation using all electron RCCSD(T).

A rigorous test of the statistical model for atom–diatom insertion reactions

open access: yesThe Journal of Chemical Physics, 2003
The statistical model of atom–diatom insertion reactions is combined with coupled-channel capture theory and used to calculate differential cross sections for the reactions of C(1D), N(2D), O(1D) and S(1D) with H2. In the case of C(1D) and S(1D), the resulting statistical differential cross sections are found to be in excellent agreement with the ...

The UV filtering potential of drop-casted layers of frustules of three diatom species

open access: yesScientific Reports, 2018
Diatoms are in focus as biological materials for a range of photonic applications. Many of these applications would require embedding a multitude of diatoms in a matrix (e.g.

Satellite remote sensing reveals a positive impact of living oyster reefs on microalgal biofilm development [PDF]

open access: yes, 2018
Satellite remote sensing (RS) is routinely used for the large-scale monitoring of microphytobenthos (MPB) biomass in intertidal mudflats and has greatly improved our knowledge of MPB spatio-temporal variability and its potential drivers.

Biodiversity of diatom population in the Masouleh stream,Guilan, Iran

open access: yesتاکسونومی و بیوسیستماتیک, 2013
Studies of stream and river ecosystems in Iran are very sketchy and their information is rather general and vague. Understanding various aspects of river systems is vital for their management and protection.

Global discovery and characterization of small non-coding RNAs in marine microalgae [PDF]

open access: yes, 2014
Background Marine phytoplankton are responsible for 50% of the CO2 that is fixed annually worldwide and contribute massively to other biogeochemical cycles in the oceans. Diatoms and coccolithophores play a significant role as the base of the marine food

Short-term variability in the sedimentary BIT index of Lake Challa, East Africa over the past 2200 years : validating the precipitation proxy [PDF]

open access: yes, 2015
. The branched vs. isoprenoid index of tetraethers (BIT index) in Lake Challa sediments has been applied as a monsoon precipitation proxy on the assumption that the primary source of branched tetraether lipids (brGDGTs) was soil washed in from the lake's

Biological markers as an additional method of determining drowning

open access: yesOpen Veterinary Journal
Background: There is no specified diagnostic procedure that can help in determining the cause of death and the diagnosis of drowning because the pathohistological signs are almost identical and non-specified.
