摘要： In this study, the role of the material chemistry and the physical surface nanostructure (topography) of polymeric films to stimulate heterogeneous nucleation of three representative organic molecules, acetaminophen, acetylsalicylic acid and glycine, was investigated. Aim of the work was to enhance current knowledge of the mechanisms involved in heterogeneous nucleation and to enable rational design and fabrication on a large scale of materials useful to control nucleation processes for scientific, technological, and industrial applications. Experimental results demonstrated that while solute-polymer interaction dictated whether a surface would behave as an effective heteronucleant, roughness cannot be generally considered as an absolute and univocal parameter in directly enhancing its nucleating activity, as the specific surface topography has to be correlated with its wetting behavior, so that chemical and physical properties will cooperate or compete to address the process.

摘要： When students are introduced to the ways in which atoms are arranged in crystal structures, transposing the textbook illustrations into three-dimensional structures is difficult for some of them. To facilitate this transition, this article describes an approach to the study of the structure of solids through a well-known monument, the Atomium in Brussels, Belgium. After a brief introduction to this monument (it represents an unit cell of iron crystal, magnified 165 billion times), a series of questions is proposed to address various topics such as crystal lattice, unit cell, body-centered cube structure, metallic crystals, typical trends for atomic radii in the periodic table, introductory solid structure calculations, and rounding in calculations. Furthermore, this exercise promotes spatial vision in students. The question-answer approach engages the students and most of them gain an appreciation for the three-dimensional structures. Students have expressed keen interest in this type of "tangible" chemistry where a concrete example of everyday life helps them to better understand chemistry topics.

摘要： In this paper, we use a variety of analytical techniques to examine the impact of local chemistry, and the mechanical properties, of the encapsulation dielectric films on the post-packaging device rejection rate of integrated circuit devices. A strong dependence of lot rejection rate (LRR) on the effective Young's modulus of the encapsulating dielectric stack is demonstrated;specifically, the device fall out rate increases with increasing Young's modulus. The increase in LRR with increasing stiffness of the encapsulating layer is attributed to the increase in thermal stress in the encapsulation dielectric stack layer and in the metal lines due to their increased constraint. This stems from the strong adhesion of the encapsulating dielectric material to the metal, thus fixing the loci of the surface planes of the metal, which could result in mechanical damage through voiding, cracking or delamination. It is also found that the increase in the local SiOH concentration leads to a decrease in the Young's modulus of the encapsulating SiO2. Thus, the engineering and optimization of the chemistry of the encapsulating dielectric are essential for improved post-packaging burn-in yields. Published by Elsevier B.V.
