The authors, who have more than two decades of combined experience teaching an atoms-first course, have gone beyond reorganizing the topics. They emphasize the particulate nature of matter throughout the book in

In this work, we provide an overview of commonly used chemical transformations for the syntheses of PET tracers in all aspects of radiochemistry, thereby highlighting recent breakthrough discoveries and contemporary challenges in the field. We discuss the use of biologicals for PET imaging and high...
The geometric property of an object (or spatial arrangement of points or atoms) of being non-superimposable on its mirror image; such an object has no mirror plane, centre of inversion or rotation–reflection axis. If the object is superimposable on its mirror image the object is achiral (...
(A) The thermally- and shock-stressed Chelyabinsk showed high numbers of nitrogen atoms within CHNO molecular formulas [133]; (B) The extremely thermally-altered Sutter’s mill reflects a loss in organic diversity, but an increase in the polysulfur domain, as compared to Murchison [21,166]....
In this approach, the defect is placed at the centre of the simulation cell and is surrounded by two spherical regions. In the inner Region 1, all atoms are allowed to relax and interactions are accounted for explicitly. In the outer Region 2b, interactions are approximated using the ...
We give an overview of the early evolution of disks, discuss the importance of the stellar high-energy radiation for disk evolution and describe the general thermal and chemical structure of disks. Finally we provide an overview of observational tracers of the gas component and disk winds....
chemical bonds that ‘hold’ the atoms and molecules together to form the material. However, this ‘conventional wisdom’ no longer holds in the nanometer regime in which, in addition to the chemical bonds, the size, dimensionality, and shape also play important roles in determining the propertie...
(using cabbage as an indicator) into an inquiry, and subsequently, we use an historical model to propose a sequence of activities based on the modeling cycle of Couso and Garrido-Espeja for lower secondary school. Finally, we identify some implications for a model-focused teaching approach for ...
During the last century, inorganic oxide compounds laid foundations for materials synthesis, characterization, and technology translation by adding new functions into devices previously dominated by main-group element semiconductor compounds. Today, comp
