Description In an advance that could lead to new treatments for a variety of diseases, MIT researchers have devised a new way to deliver messenger RNA (mRNA) into cells. Messenger RNA, a large nucleic acid that encodes genetic information, can direct cells to produce specific proteins. Unlike DNA, mRNA is no

Description The struggle to keep drinks cold during the summer is a lesson in classical phase transitions. To study phase transitions, apply heat to a substance and watch how its properties change. Add heat to water and at the so-called “critical point,” watch as it transforms into a gas (steam). Remove heat fr

Description into contact with alkanes There are claims of synthesis of a room temperature superconductor. However, these claims have not been officially accepted by scientific communities. Currently, the highest transition temperature (Tc) recognized in scientific articles is 135 K at 1 atm of Hg-Ba-Ca-Cu-O system which is a copper oxide superconductor. We packed graphite flakes into a ring-shaped polytetrafluoroethylene (PTFE) tube and further injected heptane or octane. Then we generated circulating current in this ring tube by electromagnetic induction and showed that this circulating current continues to flow continuously at room temperature for 50 days. This experiment suggests that bringing alkane into contact with graphite may result in a material with zero resistance at room temperature. In addition, we showed by means of AC resistance measurements using the two-terminal method that the resistances of graphite fibers brought into contact with various alkanes suddenly change at specific critical temperatures between 363 and 504 K. In this study, we show that after a magnetic field is applied to a single-layer graphene at room temperature, alkane is brought into contact with the single-layer graphene, then the graphene excludes the magnetic field immediately. This phenomenon demonstrates that the alkane-wetted single-layer graphene shows Meissner effect at room temperature. Furthermore, we applied a magnetic field perpendicularly to the annular single-layer graphene brought into contact with n-hexane and immediately removed the magnetic field. After that we observed that a constant magnetic field generates from this annular graphene for some time. In conclusion, the single-layer graphene brought into contact with alkane shows Meissner effect at room temperature, which provides definitive evidence for room temperature superconductivity.
