A large group index of ～28.5 is calculated from the measurement data, thus indicating achievability of time delay larger than 58ps per millimeter length of the delay line within a tuning range of 20nm. The demonstrated building blocks present a viable path for obtaining scalable TTD modules on...

Using the photonic crystal taper to minimize the coupling loss, the delay lines with 1–3mm long photonic crystal waveguides can operate up to a group index ng23 without significant loss. The large group velocity dispersion enables continuous and wavelength-tunable time delays. Measurements show a ...

Many important materials cannot be grown as single crystals in bulk form because strain destroys long-range crystallinity. Among them, alloys of group IV semiconductors, specifically SiGe alloys, have significant technological value. Using nanomembrane strain engineering methods, we demonstrate the fabricati...
on a ceramic nanomembrane by allowing a carboxyl group (—COOH) and an amine group (—NH2) to form a covalent bond in the presence of N-ethyl-N′-[3-(dimethylamino)propyl]carbodiimide hydrochloride (EDC), thereby forming an amide group (—CONH), and a method for manufacturing the same....
In the present invention, in the presence of EDC (N-ethyl-N'-[3-(dimethylamino)propyl]carbodiimide hydrochloride) on a ceramic nanomembrane, a carboxyl group (-COOH) and an amine group (-NH2) are covalently bonded to form an amide group ( -CONH) to cross-laminate GO/PEI to have ion ...
Another study from the German Neuromyelitis Optica Study Group found that the use of TPE/IA as a first-line therapy within 3 days of the onset of the attack was associated with good outcomes (40% of patients who received TPE within 3 days returned to baseline compared with less than 4% ...
