New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

The Journal of the Society of Chemical Industry, Japan, 1960 Cr2O3とカーボンブラックよりCr23C6,Cr7C3,Cr3C2を製造し,その製造条件を調べ,これら各種炭化クロムとNiとの焼結体を製造し,その焼結体の機械的性質の測定,X線解析,耐酸化試験,耐食試験を行なった。その結果,Cr7C3-Ni系焼結合金は焼結不完全で,X線解析の結果,焼結体中の炭化物相は単純なCr7C3でないことがわかった。Cr3C2-15%Ni焼結合金にCr7C3を10%まで加えた場合,機械的性質,常温におけるH2SO4,HCl,NHO3,NaOHに対する耐食性には,Cr3C2-15%Ni焼結合金と著しい差は認められなかった。耐酸化性についてはCr3C2-15%Ni焼結合金が,これにCr7C3を10%加えたものまりもすぐれた耐酸化性を有することが明らかになった。各種耐食試験 ...

Does attachment removal damage enamel? Influence of adhesive, resin, and bur on surface integrity
European Journal of Oral Sciences, Volume 134, Issue 3, June 2026.Abstract To evaluate the combination of composites, adhesive systems, and burs considering artificial accelerated aging (AAA), influence enamel roughness and morphology after attachment removal. One hundred ninety‐two bovine enamel specimens were divided according to composite type (Transbond XT, flowable, bulk‐fill flowable), adhesive system (Single ...
