In this research, we have described a facile and user-friendly protocol for the formation of 2((1H-Indole-3yl)(Phenyl)methyl)malononitrile derivatives using a recoverable and efficient TiO2 nanocatalyst. This protocol is simple and incredibly efficient fo... see more

Background. The nervous system failures are caused by the influence of various harmful industrial and environmental factors. Among them polymers play an important role. Polymeric materials (PM) and additive substances can be sources of significant disorde... see more

Aim. To develop the preparative methods for obtaining new series of biologically active substances by the three-component interaction between isatin, a-amino acids and N,N’-di(3-carboxypropenoyl)-1,2-ethylenediamine and determine the structure of the comp... see more

Multicomponent domino reactions are an effective modern approach in the synthesis of different types of organic compounds, including biologically active pyrans.Aim. To study the three-component interaction of 1,2-benzoxathiin-4(3H)-one 2,2-dioxide with di... see more

LaCl3/ClCH2COOH was used as an efficient, and recyclable catalytic system for synthesis of 8H-benzo[a]xanthe, hexahydro-1H-xanthene and pyran-10,12(11H)-dione derivatives via a one-pot three-component reaction of aldehydes, 2-naphthol, and cyclic 1,3-dica... see more

The functional properties of multi-component materials are often determined by a rearrangement of their different phases and by chemical reactions of their components. In this contribution, a material model is presented which enables computational simulat... see more

This study explores the representation of socio-cognitive components in Indonesian political multimodal news text using the framework of Systemic Functional Multimodal Discourse Analysis (SF-MDA). With the increasing prominence of multimedia in contempora... see more

Teniendo en cuenta las innovaciones metodológicas que ofrecen las mediciones de pobreza multidimensional, especialmente la desagregación que permite por áreas urbana y rural se hace evidente la brecha rural de manera particular en los países latinoamerica... see more

A recent development of heterogeneous platforms (i.e. those containing different types of computational units such as multicore CPUs, GPUs, and FPGAs) has enabled significant improvements in performance for real-time data processing. This potential, howev... see more
