The dielectric constant and loss of poly(ether ketone ketone) have been investigated over a range frequency temperature. A linear correlation between the ac conductance angular implies that hopping as dominant conduction process contributes to loss. energy density discharged efficiency polymer were measured at various temperatures. High strengths (>400 MV/m) temperatures up 150 °C achieved. increase reduction in breakdown field with increasing temperature could be attributed thermally...

Abstract Promoting tumor angiogenesis effectively and specifically to resolve tumor‐associated hypoperfusion holds promise for improving pancreatic cancer therapy. Herein, a doxorubicin (DOX) loaded smart liposome, MC‐T‐DOX, is constructed, that carries appropriately low‐density cilengitide, an α v β 3 integrin‐specific Arg‐Gly‐Asp (RGD)‐mimetic cyclic peptide, via membrane type 1‐matrix metalloproteinase (MT1‐MMP) cleavable peptide. After being administered systemically in hypoperfused...
