“…Moreover, it can be easily tailored into zerodimensional (0D) fullerenes [60], and one-dimensional (1D) carbon nanotubes (CNTs) [61]. A plentiful literature survey suggested that numerous synthesis methods have been proposed and developed including micromechanical stripping [62], chemical vapor deposition (CVD) [63], and SiC epitaxial growth method, etc Because of graphene's vast plane conjugate structure, electrons exhibit a strong delocalisation impact [64]. Consequently, graphene possesses a zero-band distance, which is characteristic of half-metallic compounds.…”

Prostate cancer (PC) is significantly increasing as a principal cause of mortality among the men’s population. Accordingly, research scholars have made tremendous development for the effective treatment of PC. Despite this, the early diagnosis of PC is a challenging task for scientific fraternities due to the plenty of demerits of currently engaged methods in terms of sensitivity, selectivity, and many more. For that reason, PC management needs exceptional alternative strategies for proficient management of PC that can endow with early diagnosis of PC and eventually it will result in promising cure of PC. Strategies involved in advanced nanomaterials especially carbon nanomaterials have gained tremendous consideration due to their numerous benefits. Notably, graphene quantum dots (GQDs) are a promising next-generation carbon nanomaterial with manifold biomedical applications such as biosensing and drug delivery in cancer and different life-threatening health issues that may be due to the versatile and tunable properties of GQDs. In a nutshell, it provides high sensitivity and selectivity towards the target biomarker of PC. In this review, the prevalence and distribution of PC, major highlights and limitations of current diagnostics and treatments, as well as recent trends for PC management have been discussed in brief. Afterward, the synthesis methods, properties, biocompatibility, and bioconjugation of GQDs along with their impact on the performance of biosensors have been summarised in brief. Finally, the application of GQD based biosensors exhibited the lowest detection limit up to femtogram in simulated and real-time samples. As a result, the applications of GQDs as novel biosensors presents plentiful advantages including high sensitivity, high selectivity, high stability, rapid response, etc of the PC biomarkers. Therefore, this review will provide the details of recent updates to prepare and extend advanced biosensing prospects using GQDs as excellent nanomaterial probes in PC and other cancer types.

“…Materiały te odznaczają się około 100-krotnie większą wytrzymałością na rozciąganie niż stal. Nanorurki charakteryzują się również bardzo dobrą odpornością na działanie podwyższonej temperatury, sięgającej nawet 2800°C, oraz są bardzo dobrymi przewodnikami ciepła (Iijima, 2002;Szadkowski i Pingot, 2016;Sahu et al, 2017). Do badań laboratoryjnych użyto nanorurek wielowarstwowych o średnicy zewnętrznej 10-20 nm, średnicy wewnętrznej 5-10 nm oraz długości 10-30 µm; • tlenek grafenu -utleniona forma grafenu, wytworzona w procesie oksydacji kryształów grafitu z mieszanką kwasu siarkowego, azotanu sodu i nadmanganianu potasu (metodą Hummersa).…”

Drilling deep holes or drilling to provide access to thermal waters places increasingly high demands on the properties of the drilling muds. Due to the very high temperature, it may be difficult to maintain the appropriate rheology of the drilling fluid during drilling, especially when an inflow of highly mineralized brines occurs. High temperatures significantly reduce the effectiveness of most of the polymeric agents currently used in the drilling muds technology, in extreme cases causing complete and irreversible damage to their structure. Polymers with ether bonds, which include starches and cellulose, are the most vulnerable. Based on the literature data, it can be concluded that the disadvantages of these polymers can be effectively compensated by the addition of synthetic polymers, e.g. sulfonated polymers. Another direction in improving the thermal resistance of drilling muds indicated in the literature is the use of carbon nanoparticles: graphene flakes and nanotubes. The article presents an analysis of the possibilities of improving thermal stability of drilling muds by using chemical agents that allow to maintain appropriate rheological and structural parameters and filtration at temperatures up to 130°C. During the tests, three types of chemicals were added to the polymer-potassium drilling mud at different concentrations. The impact of these modifications on technological parameters of the drilling mud was tested. Then, samples modified by the addition of selected agents were exposed to the temperature of 130°C for a period of 24 hours. After this time, the samples were cooled to 20°C, then their technological parameters were measured and compared with the results obtained before aging at high temperature, and based on the obtained results, the effectiveness of individual agents was assessed. Among the agents tested to protect drilling mud against the adverse effects of high temperature, the most beneficial effect was shown by potassium formate in combination with PoliAMPS.

“…The coordination behaviour of hydrazones has been well studied and depends on the pH medium, nature of the substituents and also on the position of hydrazone group relative to other moieties. As biologically active compound [7,8] hydrazone find a remarkable application to cure tumor [9], cytotoxic [10], antiproliferative, antibacterial, antiviral, antifungal [11][12][13][14], tuberculosis, leprosy, along with some mental diseases [15][16][17]. Hence many important enzymatic reactions catalyzed by the transition metal complexes take place only due to presence of Schiff bases [18,19].…”

This report describes the synthesis and exploration of novel Schiff base ligand in the form of a polymer (heptamer) which was prepared by reaction between 3,4-diacetyl-2,5-hexanedione and hydrazine hydrate in ethanol. On further reaction of Schiff base with transition metals ions (Co and Cu) leads to formation of its transition metal complexes. The structural identification of Schiff base ligand and its transition metal complexes were characterized by classical structural techniques like FT-IR, NMR and mass spectra. The free ligand and its transition metal complexes have been screened for in vitro biological activities against various strains of bacteria and fungi. The prepared Schiff base and its metal complexes were also screened for antiangiogenic activity. The results have shown the remarkable antimicrobial and antiangiogenic activities of the Schiff base and its metal complexes.
