After casting, cementitious materials exhibit a continuous change in the mechanical properties with time due to a chemical reaction known as hydration. In addition, these materials also exhibit a change in state, from a fluid to a solid, in the first few hours. Conventionally, changes in the ...
Optical techniques for solid-state materials characterization Over the last century, numerous optical techniques have been developed to characterize materials, giving insight into their optical, electronic, magnetic, and structural properties and elucidating such diverse phenomena as high-temperatu...

The distance between two successive perovskite layers, which is dependent on the molecular chain length, appears very short in the crystalline initial form. The polymorphism has been studied by thermal and crystallographic investigations on both powder and single-crystal materials. Five crystalline forms...
‘the capacity of past states or experiences to influence present or future responses of a community’2, is critical to predict a disturbance effect on ecosystems. The memory effect is transmitted as legacies of species and materials, which are prerequisites. We here examined the extent to which...
debated2,3. To answer these questions, we have to study these materials under reaction conditions because the dynamical working structures may be different from those characterized under vacuum. The need to clarify these structure–property relationships in catalyst materials has spurred the adaption of...
2. Materials and methods 2.1. Sample description The data stem from two Trypanosoma brucei transgenic cell lines overexpressing either TbHslV-wild type or TbHslV-mutant protease. The T. brucei mitochondrion contains a proteasome-like ATP-dependent protease named TbHslVU that plays a critical role ...
