an ion imprinted polymer (iip) based on aniline-formaldehyde was synthesized and then modified with extra aniline as cross-linker in the presence and absence of sr (ii) as the template to produce ion imprinted poly(aniline-formaldehyde) (iipaf) and non imprinted poly(aniline-formaldehyde) (nipaf). the sorbent was characterized by fourier transform infrared spectroscopy and was used for solid ph...

Commonly used implants for therapeutic approaches of non-systemically impaired bone do not sufficiently support the healing process of osteoporotic bone. Since strontium (II) has been proven as an effective anti-osteoporotic drug new types of strontium enriched calcium phosphate bone cements were developed. As osteoporosis is characterized by an imbalance of osteoblast and osteoclast activity t...

Ab initio QMCF-MD simulations of aqueous 18-crown-6 (18C6) and strontium(II)-18-crown-6 (18C6-Sr) were performed to gather insight into their hydration properties. Strongly different characteristics were found for the two solutes in terms of structure and dynamics such as H-bonding. They, however, have in common that their backbone shows high flexibility in aqueous medium, adopting structures s...

In the present investigation, three different solid wastes namely almond green hull, eggplant hull, and moss were initially treated and used as adsorbents for the adsorption of strontium ion from aqueous solutions. Adsorbent types and chemical treatments are proved to have effective roles on the adsorption of Sr(II) ion. Among the three adsorbents, almond green hull demonstrated strong affinity...

A facile bottom-up approach for the controlled self-assembly of infinite strontium vanadium oxide chains is presented. Two novel one-dimensional strontium-linked polyoxovanadate chains have been isolated by linkage of decavanadate clusters with strontium(ii) ions. To control the architecture dimensions, urea was used as a critical control parameter which allowed tuning of the intra- and intermo...

Osteoarthritis (OA) is a joint disease that most commonly accompanied with pain and joint deformity which eventually leads to disability. Burden of OA will be accounted second in women and fourth in men in Iran. Most therapies of knee osteoarthritis are symptomatic treatment. Recently, strontium ranolate are used as a new agent for handling of post menopausal osteoporosis and provided reduces i...

Strontium can replace calcium in triggering neurotransmitter release, although peak release is reduced and the duration of release is prolonged. Strontium has therefore become useful in probing release, but its mechanism of action is not well understood. Here we study the action of strontium at the granule cell to Purkinje cell synapse in mouse cerebellar slices. Presynaptic residual strontium ...

In the title compound, [Sr(C(10)H(15))(2)(C(10)H(8)N(2))], the Sr-N distances are 2.624 (3) and 2.676 (3) Å, the Sr⋯Cp ring centroid distances are 2.571 and 2.561 Å and the N-C-C-N torsion angle in the bipyridine ligand is -2.2 (4)°. Inter-estingly, the bipyridine ligand is tilted. The angle between the plane defined by the Sr atom and the two bipyridyl N atoms and the plane defined by the 12 a...
