Recently, it was discovered that by defect modification, the electromechanical responses of P(VDF-TrFE) based ferroelectric polymers can be modified significantly. Here, we present a room temperature phase diagram which illustrates the compositions of two classes of PVDF based polymers investigated in this paper. In the compositions at PVDF homopolymer, by including bulky monomers such as CTFE (chlorotrifluoroethylene),...
It is important for laser-induced thermal therapy to exactly destroy all tumor cells within a desired region. In medical practice, it has been demonstrated that nano particles will extravasate and accumulate in tumors and serve to enhance absorptance of near infrared light. However, few efforts have yet been made to evaluate such improvement. This study proposed using infrared images to quantify the...
Cryosurgery is a minimally invasive surgical technique that employs the destructive effect of freezing to eradicate benign or malignant tumors which are difficult or even impossible to be extirpated by conventional surgery. Recently, we proposed a method for flexibly controlling the freezing scale during cryosurgery by percutaneously injecting thermally important functional solutions into the target...
