The first example of polymeric lanthanide -trifluoroacetates in chemical solution deposition of up-converting NaGdF:Yb,Er,Nd thin films.

A series of lanthanide -trifluoroacetates {(detaH)[La(tfa)](CHCN)(HO)} and (detaH)[Ln(tfa)] (Ln = Pr-Eu), mixed-ligand complexes [La(tfa)(CHCN)(HO)], [Gd(tfa)(deta)](PrOH) and [Yb(tfa)(deta)](tfa), as well as detaH(tfa) were isolated and characterized. All lanthanide -trifluoroacetates contain two types of 1D anionic chains [Ln(tfa)] and cavities occupied by detaH cations and solvating HO and CHCN molecules. The thermal behavior of (detaH)[Ln(tfa)] in air is investigated by TGA, VT-PXRD and total X-ray scattering with PDF analysis, and the formation of metal fluorides occurs upon heating to 300 °C.

Tuning the Cerium-Based Metal-Organic Framework Formation by Template Effect and Precursor Selection.

The novel metal-organic framework [(CH)NH][Ce(bdc)(DMF)]·2HO (, Hbdc-terephthalic acid, DMF-,-dimethylformamide) was synthesized by a simple solvothermal method. has 3D connectivity of type with a dinuclear fragment connected with eight neighbors, while three types of guest species are residing in its pores: water, DMF, and dimethylammonium cations. Dimethylamine was demonstrated to have a decisive templating effect on the formation of , as its deliberate addition to the solvothermal reaction allows the reproducible synthesis of the new framework.

Partially Ordered Lanthanide Carboxylates with a Highly Adaptable 1D Polymeric Structure.

A new family of 14 isostructural [Ln(piv)(en)] lanthanide pivalate (piv, 2,2-dimethylpropanoate) complexes with ethylenediamine (en) was synthesized by a topology-preserving transformation from 1D coordination polymers [Ln(piv)]. The crystal structures of the compounds were determined by single-crystal and powder X-ray diffraction, which demonstrated that despite the regular ligand arrangement within the chains, the latter are intricately packed within the partially ordered crystal, as only two of four ligands are strictly bound by the translational symmetry. The peculiarities of the lanthanide coordination environment were explored by total X-ray scattering with pair distribution function analysis.

A Family of Lanthanide Hydroxo Carboxylates with 1D Polymeric Topology and Ln Butterfly Core Exhibits Switchable Supramolecular Arrangement.

The unique family of coordination polymers [Ln(OH)(piv)(HO)] of 11 lanthanides (Ln = La-Er) has been prepared by a simple solution method based on controlled hydrolysis. The ribbon-like polymeric structure consisting of connected tetranuclear clusters and supported by pivalate ligands and a framework of H-bonds has been revealed by single-crystal X-ray diffraction. While the compounds demonstrate similar PXRD patterns and unit cell parameters, the joint single-crystal XRD and pair distribution function data suggest the significant local structure change along the lanthanide series.

[ЕXPERIMENTAL ESTIMATION OF THE LOCAL APPLICATION EFFICACY OF BIOLOGICAL STIMULATOR FOR THE SOFT TISSUES REPARATION IN TREATMENT OF CHRONIC GASTRIC ULCERS].

Results of experimental investigation for studying of the local application possibility for the reparative processes stimulators, including autologic purified lipoaspirate, dalargin and a platelet—rich plasma (PRP) for treatment of chronic gastric ulcers, were analyzed. The advantages of PRP application, as the growth factors donator, independently and in combination with dalargin, were proved. The PRP capacity to stimulate the fibroblasts activity and creation of vessels in young connective tissue was proved, what have leaded to the ulcer tissues oxygenation improvement and cellular proliferation promotion, acceleration of the connective tissue maturation, and the ulcer healing.
