Jan 21, 2018 · Diatoms (pictured below) are a common type of unicellular phytoplankton that likely originated around the Jurassic period. Diatoms can form colonies characterized by particular shapes (e.g., stars, fans, and ribbons) and are encapsulated by a unique cell wall composed of silica, termed a frustule.

For the spin state of the molecules (singlet state in all cases), the default spin formalism was followed in the calculations, and default Gaussian 09 values were adopted for the numerical integration grids, self-consistent-field (SCF) and geometry optimization convergence criteria. Geometries were optimized without symmetry restrictions.

Based on a theoretical model where the nuclear spins remain unchanged during a collision, we provide an analytical and general expression for the nuclear spin state-to-state distribution of an ultracold diatom-diatom chemical reaction in a magnetic field, for given rotational transitions of the molecules. Peptides and proteins were identified during a controlled laboratory degradation of the marine diatom Thalassiosira weissflogii by a surface seawater microbiome. Samples from each time point were processed both with and without the protease trypsin, allowing a partial differentiation between peptides produced naturally by microbial enzymatic degradation and peptides produced from the. Since diatoms are known to store nitrate in concentrations of up to 274 mmol L −1, the diatoms present in the sediment readily explain the measured sedimentary intracellular NO 3 −. It needs to be noted though that the cellular fucoxanthin content may vary with environmental factors and the physiological state of the diatoms.

Keywords: Photo-CIDNP MAS NMR, Diatoms, Cyclotella meneghiniana 1 Introduction The solid-state photo-CIDNP effect is a spin-chemical effect in which transiently nuclear spin order far from Boltz-mann equilibrium occurs, which can be detected by solid-state NMR methods as modification of the equilibrium signal intensity. F. Thus at ultralow temperatures hyperfine-state-changing collisions are rigorously forbidden. II. MODEL A. Hamiltonian Our investigation of molecular collisions follows the model of diatom-diatom scattering originally due to@13,14#, but modified to incorporate the electronic spin of oxygen molecules. The O2(3S g 2)2O 2(3S g 2) dimer has a spin. Dec 01, 2008 · The atom is taken to be structureless while the molecule can be in its singlet, doublet, or triplet spin states and can be treated as either a rigid rotor or a rovibrational target.

Controlling charge-spin current conversion by electric fields is crucial in spintronic devices, which can now be realized in diatom ferroelectric semiconductor GeTe. It is well demonstrated that ferroelectricity can change the spin texture in this compound. The spin-orbit dependence of the chemiluminescence pathway was found to be substantial for the CH 3 I and CH 2 I 2 reactions and similar to that previously observed for halogen diatom and alkyl bromide reagents. By contrast, no spin-orbit effect was observed for Ca(3 P 0)+SF 6. These results are discussed in terms of our previously.

Assessing the state of the Barents Sea using indicators: how, when, and.
Diatoms are unicellular, photosynthetic bio-mineralization marine organisms that possess a bio-silica shell, which is called the frustule, with two di-mensional (2-D) periodic pores [1,2]. The unique optical, physical, and chemical properties of diatom frustules have attracted long-lasting interests for more than two centuries [3-5].

The different combinations of spin angular momentum can be calculated as: s1(z) = +1/2 +1/2 −1/2 −1/2 s2(z) = +1/2 −1/2 +1/2 −1/2 Sz= +1 0 0 −1 Hence, the spin angular momentums of two p or d-electrons can interact in four ways, creating four combinations; out of which, two quantum-mechanically allowed series can be fashioned.

The low values of T c 0 in this regime allow us to reveal and probe deep into the normal state by applying H up to 35 T, because we find H c2 ∼ 20 T in LESCO with x = 0.10 and H c2 ∼ 25 T in LNSCO with x = 0.12, as shown below. Fields perpendicular to CuO 2 planes, i.e., along the c axis, enhance both spin (11, 12) and charge orders (13, 14).

Aureochromes constitute a family of blue light (BL) receptors which are found exclusively in heterokont algae such as diatoms (Bacillariophyceae) and yellow-green algae (Xanthophyceae). Previous studies on the diatom Phaeodactylum tricornutum indicate that the formation of a high light acclimated phenotype is mediated by the absorption of BL and that aureochromes might play an important role.
