Hyperthermia opens a safe alternative for cancer treatment. Researchers synthesize new materials that can be successfully used for the biomedical application. We have synthesized Mn1-xZnxFe2O4 (0.2 ≤ x ≤ 1.0, in the steps of 0.2) and coated the samples with chitosan. The structural properties of the...

Bangladesh reported the highest number of annual deaths (n = 281) related to dengue virus infection in 2022 since the virus reappeared in the country in 2000. Earlier studies showed that >92% of the annual cases occurred between the months of August and September. The 2022 outbreak is characterized ...
