A combination treatment with topical tacrolimus and an excimer laser may be useful as an induction therapy for up to 6 months, but continuation of this therapy for > 6 months might not provide a better final outcome than monotherapy.

The microwave dielectric properties of Ca[(Li1/3Nb2/3)1−xMx]O3−δ (M = Sn, Ti, 0 ≤ x ≤ 0.5) ceramics were investigated. In general, the ceramics prepared were multiphase materials. However, single-phase specimens having orthorhombic perovskite structure similar to CaTiO3 could be obtained in the vicinity of Sn = 0.2 to 0.3, and Ti = 0.2. As Sn concentration increased, the dielectric constant (εr) decreased and the quality factor (Q) significantly increased within the limited Sn concentration. As Ti concentration increased, the dielectric constant (εr) increased, the quality factor (Q) decreased, and the temperature coefficient of resonant frequency (τf) changed from a negative to positive value. The temperature coefficient of resonant frequency of 0 ppm/°C was realized at Ti = 0.2. The Q · fo value and εr for this composition were found to be 26100 GHz and 38.6, respectively.

Titanium dioxide thin film doped with nitrogen was deposited at 420 °C on p-type silicon substrate by metalorganic chemical vapor deposition using titanium tetra-isopropoxide and nitrous oxide. From an x-ray diffraction result, when deposited at 420 °C, only the anatase (101) peak and (200) peak were observed. Raman spectroscopy confirmed the presence of anatase phase without any rutile or TiN phase. X-ray photoelectron spectrum revealed that nitrogen was doped into the lattice of TiO2 anatase. In the bulk of the film nitrogen peak was observed, and the spectrum of Ti 2p core level confirmed titanium–nitrogen bonding due to nitrogen incorporation into the anatase lattice.
