Nearly sing.e-phase and polycrystalline charg.-density-wave compound K0.3MoO3 have been prepared by using.a simple method. In this work, K2CO3 and MoOs were used as starting.materials and reacted by hot isostatic pressing.（HIP） sintering. The product is nearly sing.e phase K0.3MoO3 determined by X-ray powder diffraction （XrD） and energ. dispersive spectroscopy （EDS）. Measurement of temperature dependence of resistivity reveals that the transport property of polycrystalline K0.3MoO3 obviously differs from that of sing.e crystal due to the g.ain boundaries and the anisotropic structure in this kind of compound.

During.the COVID-19 crisis, the need to stay at home has increased dramatically. In addition, the number of sickpeople, especially elderly persons, has increased exponentially. In such a scenario, home monitoring.of patientscan ensure remote healthcare at home using.advanced technolog.es such as the Internet of Medical Thing. (IoMT).The IoMT can monitor and transmit sensitive health data;however, it may be vulnerable to various attacks. In thispaper, an efficient healthcare security system is proposed for IoMT applications. In the proposed system, themedical sensors can transmit sensed encrypted health data via a mobile application to the doctor for ***, three consortium blockchains are constructed for load balancing.of transactions and reducing.transactionlatency. They store the credentials of system entities, doctors' prescriptions and recommendations according.to thedata transmitted via mobile applications, and the medical treatment process. Besides, cancelable biometrics areused for providing.authentication and increasing.the security of the proposed medical system. The investig.tionalresults show that the proposed system outperforms existing.work where the proposed model consumed lessprocessing.time by values of 18%, 22%, and 40%, and less energ. for processing.a 200 KB file by values of 9%,13%, and 17%. Finally, the proposed model consumed less memory usag. by values of 7%, 7%, and 18.75%. Fromthese results, it is clear that the proposed system g.ves a very reliable and secure performance for efficientlysecuring.medical applications.
