    Opis:
    Key protocols of the preparation of conjugated nitroalkenes were reviewed and critically discussed. It was established, that optimal strategy for the obtaining of target compounds are small molecules extrusion processes from saturated nitro-compounds. Among them, the most universal methodologies based on carboxylic acids elimination have been discussed, which provide for smooth applications.

    Opis:
    Several methods exist for the synthesis of alkanes including Corey’s synthesis, Wurtz reaction, reduction of alcohols and aldehydes, Kolbe’s electrolysis, hydrogenation of alkenes, and Grignard reaction. Among the available methods, the age-long Corey’s synthesis presents robust advantages of yielding symmetrical, unsymmetrical, straight chain and branched chain alkanes. Moreover, it allows of generating high yields of alkanes by utilizing primary alkyl halide and an array of lithium dialkyl copper ranging from primary, secondary to tertiary. Corey’s synthesis has also been implicated in the synthesis of various organic compounds such as (+)-taylorione, terminal alkynes, caribenol A, ketones, and aldehydes. In this work, an explanation of the general concept in the Corey’s synthesis is provided. Furthermore, specific examples of Corey’s reactions and modifications are discussed. Finally, an outlook into the benefits of the Corey’s synthesis in present-day organic synthesis is provided, which is expected to enhance the understanding of organic reaction mechanisms for the development of various organic compounds as drugs for treating diseases.

    Opis:
    Metal-organic frameworks (MOFs) are a class of porous hybrid materials comprising metal ion-based vertices and multitopic organic ligands (linkers). The possibility of combining a wide range of metals with similarly large number of available ligands opens ways to design the structures meeting specific purposes. At present, many potential applications of MOFs may require them to be constructed at the nanometer length scale (nanoMOFs). The possibility of filling the track-etched membrane pores with MOF HKUST-1 has been demonstrated in this work.

    Opis:
    The usage of forming principles of wild life got the new quality and received a name of architectural and bionic process and became one of the trends of architecture in the world architectural practice for the last 40 years. Bionics is an innovative architectural style that took all the best from nature: relief outlines and forms. It can be called architecture of future and its aim is synthesis of nature and modern technologies.

    Opis:
    In recent years, the number of materials used as drug delivery systems (DDS) has increased dramatically. The widespread use of DDSs has improved both the safety and efficacy of therapy. The systems currently in use pose numerous drawbacks and require proper improvements. Although many modern materials are being developed, metal-organic frameworks (MOFs) deserve special attention. Thermal and chemical stability, high specific surface area, low toxicity, high biocompatibility, and great potential for modification are the main features enabling MOFs to be used as DDS. In this review, we describe MOFs, their structure, synthesis, and characterization, as well as drug loading, drug release kinetics, and bioassays. A critical approach is to outline the disadvantages as well as the limitations of MOFs and to identify areas that need to be studied more thoroughly. Nonetheless, the prospective nature of MOFs as DDS and potential adsorbents in overdose or poisoning is presented and highlighted.
