Wafer bonding of β-Ga2O3 and N-polar GaN single crystal substrates is demonstrated by adding ZnO as a “glue” interlayer. The wafers are fully bonded such that Newton rings not observed. Temperature-dependent current-voltage (I–V) measurements conducted on the as-bonded Ga2O3/ZnO/N-polar test structure after annealing at 600 °C 1100 °C. impact post-annealing temperature electrical structural cha...

The constituents of the title 1:1 co-crystal, C(7)H(6)O(2)·C(14)H(12)N(2), are connected into dimeric aggregates by a bifurcated O-H⋯N hydrogen bond; the hydroxyl-H atom is hydrogen bonded to the two N atoms of the 2,9-dimethyl-phenanthroline. The hydrogen-bonded residues are almost orthogonal to each other [dihedral angle = 78.56 (7) °]. In the crystal packing, the aggregates are assembled int...

In the title compound, C(17)H(18)N(4)O(5)·2C(3)H(7)NO, two solvent mol-ecules are linked to the main mol-ecule via N-H⋯O and O-H⋯O hydrogen bonds, forming a hydrogen-bonded trimer. Intra-molecular O-H⋯N hydrogen bonds influence the mol-ecular conformation of the main mol-ecule, and the two benzene rings form a dihedral angle of 10.55 (18)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds l...

Introduction: To achieve acceptable clinical performance, a ceramic veneer must be bonded to enamel by well-polymerized resin cement. Among different factors, thickness and translucency of the ceramic may affect the resin cement polymerization. Thus, the current study evaluated the effect of the thickness and translucency of lithium disilicate ceramic on light-cured resin cement bond strength t...

The mol-ecule of buthalital, (I) [systematic name: 5-(2-methyl-prop-yl)-5-(prop-2-en-1-yl)-2-sulfanyl-idene-1,3-diazinane-4,6-dione], C11H16N2O2S, exhibits a planar pyrimidine ring, whereas the pyrimidine ring of methitural, (II) [systematic name: 5-(1-methyl-but-yl)-5-[2-(methyl-sulfan-yl)eth-yl]-2-sulfanyl-idene-1,3-diazinane-4,6-dione], C12H20N2O2S2, is slightly puckered. (I) and (II) contai...

In 2-amino-6-methylpyridin-1-ium 2-carboxy-3,4,5,6-tetrachlorobenzoate, C(6)H(9)N(2)(+)·C(8)HCl(4)O(4)(-), there are two perpendicular chains of hydrogen-bonded ions, one arising from the interaction between 2-carboxy-3,4,5,6-tetrachlorobenzoate ions and the other from the interaction between the 2-amino-6-methylpyridin-1-ium and 2-carboxy-3,4,5,6-tetrachlorobenzoate ions. These chains combine ...
