Linear-field particle acceleration in free space (which is distinct from geometries like the linac that requires components in the vicinity of the particle) has been studied for over 20 years, and its ability to eventually produce high-quality, high energy...

Complex formation between lithium (Li(+)) ions and electrolyte molecules would affect the ionic conductivity through the electrolyte in lithium-ion batteries (LIBs). We hence revisit the solvation number of Li(+) in the most commonly used ethylene carbonate (EC) electrolyte. The...

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...

Inorg Chem. 2017 Jul 03;56(13):7354-7359. doi: 10.1021/acs.inorgchem.7b00245. Epub 2017 Jun 21.

Quasicrystals (QCs) are well-ordered but aperiodic crystals with classically forbidden symmetries (such as 5-fold). High-dimensional (HD) crystallography is a standard method to locate atom positions explicitly. However, in practice, it is still challenging because of its complexity. Here, we...
