... of preservice Spanish teachers’ learning light and color concepts when one experimental group was engaged with hyper-realistic optical simulations such as a coin immersed in water, a convergent lens, chromatic aberration and a concave mirror and another control group was involved with more traditional didactic...

... the substrate was bent toward the inside (concave like feature), it experienced more compression and hence the resistance dropped, as shown in Fig. 4.13(a) . In contrast, when it was bent outward (convex like feature), the resistance increased. This suggests that a small change in the curvature of the sample...

... is suggested due to its lower thermal mass, an example of which is depicted in Fig. 8.6(c) . Many strategies have been suggested to improve the heat distribution. One such example describes a fabricated concave-shaped structure of the suspended membrane in which Pt heating elements were incorporated. Due...

... method is limited in boule length due to the free carrier absorption in the infrared causing problems in heat removal and a convex-to-concave interface inversion, which results in a corkscrew or spiral formation ( Baldini et al., 2018 ). EFG grown β-Ga₂O₃ crystals do...

... zeolites, some activated carbons, and certain porous oxides). When the amount of adsorbed reaches a limiting value and becomes concave to the p/p0 axis, a type I isotherm forms. Instead of the internal surface area, the accessible micropore volume controls this limiting absorption...

... that of the normal flat state [Fig. 2.5(b) ]. The increasing emission was attributed to the spreading of the solid emission angle under the concave upward condition of basic emitting Se–In–In–Se units ( Ho and Chu, 2015 ). PL studies also shed light on the fact that InSe exhibits a direct bandgap over a wide range...
