Computer Modeling of the Soderberg’s Cell with the Use of Anode’s Cooling Fins

На электролизерах с анодом Содерберга существует проблема перегрева анодной массы и увеличения конуса спекания в центре анода и низких температур (вплоть до смерзания в зимнее время) на периферии. Увеличение высоты конуса спекания в центральной части отрицательно влияет на формирование анода и, как следствие, на физико-механические свойства анода, увеличивая пористость, удельное электросопротивление и снижая механическую прочность. В данной статье представлены результаты моделирования температурных полей электролизеров С8-БМ с ребрами охлаждения в теле анодаSoderberg’s cell there is the problem of overheating of the anode paste and increasing mass of the bakedome in the center of the anode and low temperatures (down to freezing in winter) in the periphery. Increasing the height of the bakedome in the central part affects the formation of the anode and consequently on the physical and mechanical properties of the anode, increasing the porosity, electrical resistance and reducing mechanical strength [1]. This paper presents the simulation results of cell’s temperature fields (S8-BM) with anode’s cooling fin

Towards understanding the triggering of the malignant cell death in high-efficiency magneto-mechanical anticancer therapy

The paper discusses schemes for implementing magneto-mechanical anticancer therapy and the most probable scenarios of damaging mechanical effects on the membranes of malignant cells by targeted magnetic nanoparticles (MNPs) selectively bound to membrane mechanoreceptors employing aptamers. The conditions for the selective triggering of the malignant cell apoptosis in a low-frequency non-heating alternating magnetic field, corresponding to the exceeding threshold value of the force acting on the membrane and its mechanoreceptors, are established using a nanoparticle dynamic simulation. The requirements for the functionality of MNPs and their suitability for biomedical applications are analyzed. Attention is paid to the possibility of the formation of magnetite nanoparticle aggregates in an external magnetic field and their localization near tumor cell membranes. It is shown that the scenario involving the process of aggregation of magnetite nanoparticles provides a sufficient magneto-mechanical impact to achieve a therapeutic effect. A possible explanation for the experimentally established fact of successful application of magneto-mechanical therapy using magnetite nanoparticles is presented, in which complete suppression of the Ehrlich carcinoma in an alternating magnetic field as a response to a magneto-mechanical stimulus was demonstrated. This result confirmed the possibility of using the method for high efficiency treatment of malignant neoplasms. The paper provides an extensive review of key publications and the state of the art in this area
