Global Performance Indices for Dynamic Crystals as Organic Thermal Actuators

Crystal adaptronics is an emergent materials science discipline at the intersection of solid-state chemistry and mechanical engineering that explores the dynamic nature of mechanically reconfigurable, motile, and explosive crystals. Adaptive molecular crystals bring to materials science a qualitatively new set of properties that associate long-range structural order with softness and mechanical compliance. However, the full potential of this class of materials remains underexplored and they have not been considered as materials of choice in an engineer's toolbox. A set of general performance metrics that can be used for quantification of the performance of these prospective dynamic materials as micro- and macroactuators is presented. The indices are calculated on two selected representatives of thermosalient solids—materials that undergo rapid martensitic transitions accompanied with macroscopic locomotion. Benchmarking of their performance against extensive set of data for the existing actuator classes and visualization using materials property charts uncover the hidden potential and advantages of dynamic crystals, while they also reveal their drawbacks for actual application as actuators. Altogether the results indicate that, if the challenges with fabrication and implementation in devices are overcome, adaptive molecular crystals can have far-reaching implications for emerging fields such as smart microelectronics and soft microrobotics.

The elements of forming traditional Turkish cities: Examination of houses and streets in historical city of Erzurum

When the historical parts of cities—which are the cultural mosaics and which reflect the feelings, thoughts, tendencies, life experiences and the accumulations of the periods in which they were built—begin to disappear, it affects the historical identities of the cities negatively. Investigating, learning, documenting and transferring to the future the values of these spaces, which are bridges between past and future, are vitally important for the maintenance of the cities. This analytical study carried out in Üç Kümbetler and its vicinity in the historical city of Erzurum—where historical and traditional urban elements such as religious buildings, traditional houses, streets, and fountains are intense—aimed at fulfilling these ends.

Soil management effects on aggregate dynamics in semiarid Aragon (NE Spain)

During decades, in semiarid rainfed Aragon, intensive soil tillage and low crop residue input have led to the loss of soil structure and soil degradation. Conservation tillage and cropping intensification can improve soil structure in these areas. The objective of this study was to determine the influence of three different tillage systems (traditional tillage, reduced tillage and no-tillage) under two cropping systems (fallow-barley rotation and barley monoculture) on soil aggregation dynamics during a cropping season. A decrease in tillage intensity resulted in a higher mean size of dry aggregates and a greater water aggregate stability in both cropping systems particularly under no-tillage.
