Experimental Studies on the Thermal Properties and Decomposition Course of a Novel Class of Heterocyclic Anticancer Drug Candidates

Marta Worzakowska et al.

Summary: This study investigates the thermal properties and decomposition process of a new class of potential anticancer drugs containing asymmetrical triazine template. The experimental methods used were differential scanning calorimetry (DSC) and simultaneous thermogravimetry/differential scanning calorimetry (TG/DTG/DSC) coupled online with Fourier transform infrared spectroscopy (FTIR) and quadrupole mass spectrometry (QMS). The results show that the melting points of the compounds depend on the position and type of substituents, but not on the furnace atmosphere. The compounds exhibit high thermal stability in both inert and oxidizing conditions, with most of them being more stable in oxidizing conditions. The pyrolysis process releases volatiles such as NH3, HNCO, HCN, CO, CO2, H2O, NO2, aromatic amine derivatives, alkenes, and HCl, while the oxidative decomposition process emits NH3, CO2, CO, HCN, HNCO, H2O, aromatics, HCl, N-2, NO2, NH2OH, and (CN)(2). The decomposition is initiated by a radical mechanism and involves the cleavage of C-N and C-C bonds (inert conditions) as well as the reaction of volatiles and residues with oxygen (oxidizing conditions).

The addition of carbon nanotubes modifies the biological, physicochemical, and electrical properties of carbon nanofiber composites

Sebastian Wilk et al.

Summary: In this study, carbon nanofiber (CNF) - carbon nanotube (CNT) nanofibrous composites were fabricated by thermal treatment of electrospun polyacrylonitrile precursor. The presence of CNTs affected the structure and chemical composition of the CNF composites and improved their antibacterial performance. These materials exhibited excellent electrical conductivity, cytocompatibility, and antibacterial properties.

Thermal removal of partial nitrogen atoms in N-doped graphene for enhanced catalytic oxidation

Yang Zhao et al.

Summary: This study demonstrates that nitrogen-doped graphene with structural defects can effectively activate peroxymonosulfate for bisphenol A degradation. The synergistic effect between doped nitrogen atoms and created structural defects enhances the catalytic performance. The nonradical pathway is proposed to play the dominant role in the PMS activation process.

Summary: Every year, the American Cancer Society projects the numbers of new cancer cases and deaths in the United States, with the latest data showing a significant decline in lung cancer mortality, while prostate cancer mortality has plateaued and breast and colorectal cancer mortality have slowed. Improvements in treatment have accelerated progress against lung cancer, leading to a record drop in overall cancer mortality.

Covalently bonded surface functional groups on carbon nanotubes: from molecular modeling to practical applications

Aleksandra Benko et al.

Summary: The study investigates the impact of chemical functionalization on the electronic properties of multi-walled carbon nanotubes, affecting the electrophoretic deposition process for fabricating high-quality all-carbon nanotube layers. Surface modifications with various functional groups were shown to alter the electronic properties of the nanotubes, as evidenced by changes in work function measurements and dipole moments. This research provides insights into the rational design of carbon-based biomaterials.
