Ann Dermatol. 2008 Sep;20(3):113-9. doi: 10.5021/ad.2008.20.3.113. Epub 2008 Sep 30.

BACKGROUND: Transforming growth factor-β (TGF-β), a multifunctional growth factor, has three isoforms: TGF-β1, TGF-β2, and TGF-β3. Different isoforms of TGF-β are associated with different proliferation and differentiation states of the epidermis. Narrow band ultraviolet B (NBUVB) emits a concentrated...

J Phys Chem Lett. 2015 Apr 02;6(7):1155-61. doi: 10.1021/acs.jpclett.5b00389. Epub 2015 Mar 17.

Ferroelectricity has been believed to be an important but controversial origin of the excellent photovoltaic performance of organometal trihalide perovskites (OTPs). Here we investigate the ferroelectricity of a prototype OTP, CH3NH3PbI3 (MAPbI3), both theoretically and experimentally. Our first-principles calculations...

Ferroelectric perovskites with strongly elongated unit cells (c/a > 1.2) are of particular interest for realizing giant polarization induced by significant ionic off-center displacements. Here we show that epitaxial BiFe0.6Ga0.4O3 (BFGO) thin films exhibit a stable super-tetragonal-like structure with...
