TL;DR: This Perspective argues that electronics is poised to enter a new era of scaling – hyper-scaling – driven by advances in beyond-Boltzmann transistors, embedded non-volatile memories, monolithic three-dimensional integration and heterogeneous integration techniques.
Abstract: In the past five decades, the semiconductor industry has gone through two distinct eras of scaling: the geometric (or classical) scaling era and the equivalent (or effective) scaling era. As transistor and memory features approach 10 nanometres, it is apparent that room for further scaling in the horizontal direction is running out. In addition, the rise of data abundant computing is exacerbating the interconnect bottleneck that exists in conventional computing architecture between the compute cores and the memory blocks. Here we argue that electronics is poised to enter a new, third era of scaling — hyper-scaling — in which resources are added when needed to meet the demands of data abundant workloads. This era will be driven by advances in beyond-Boltzmann transistors, embedded non-volatile memories, monolithic three-dimensional integration and heterogeneous integration techniques. This Perspective argues that electronics is poised to enter a new era of scaling – hyper-scaling – driven by advances in beyond-Boltzmann transistors, embedded non-volatile memories, monolithic three-dimensional integration, and heterogeneous integration techniques.

TL;DR: In this article, the authors investigated the nature of perovskite absorption features and optical properties and proposed a band structure composed of two distinct transitions that is consistent with the various spectral features and kinetic behavior of the CH3NH3PbI3 excited state.
Abstract: The rapid increase in efficiency of methylammonium lead halide perovskite solar cells necessitates further investigation into the nature of perovskite absorption features and optical properties. Films obtained from the deposition of solutions containing lead halides and the CH3NH3+ organic cation is known to yield the CH3NH3PbI3 perovskite structure upon annealing. In examining the precursor solution used in the processing of CH3NH3PbI3 solar cells, we find that Pb2+ readily forms plumbate complexes in the presence of excess iodide ions and exhibits characteristic absorption bands at 370 (PbI3−) and 425 nm (PbI42−). Through comparative spectral analysis of the absorption features of charge transfer complexes in the solution phase and the final solid-state perovskite films, we are able to fully classify the absorption features in the excited state of CH3NH3PbI3 across the transient absorption spectrum recorded following laser pulse excitation. In particular, we attribute the broad photoinduced absorption to a charge-transfer excited state, and show correlation between the photoinduced absorption and 480 nm bleach signals. These observations lead us to propose a band structure composed of two distinct transitions that is consistent with the various spectral features and kinetic behavior of the CH3NH3PbI3 excited state. Characterization of this unique dual excited state nature provides further insight into the optoelectronic behavior of hybrid lead halide perovskite films and thus aids in elucidating their exceptional photovoltaic properties.

TL;DR: Several of these means of emulsion and thin-film stabilization of emulsions in petroleum-water mixtures are reviewed in this paper, as well as some of the key physical and chemical means of characterizing both the materials that stabilize the emelsions and the means of charactersizing the oil-water interface and the emulsion films themselves.
Abstract: Emulsions of oil droplets in water but more typically water droplets in oil are common in the production, transportation, and refining of petroleum and related products. Emulsions of water in petroleum or petroleum-derived liquids can be stabilized by a variety of surface-active compounds and components present in petroleum and also with which petroleum comes into contact. These include asphaltenes, carboxylic organic acids of various types, fine inorganic particles, and combinations of these three types of materials. Several of these means of emulsion and thin-film stabilization of emulsions in petroleum–water mixtures are reviewed here, as well as some of the key physical and chemical means of characterizing both the materials that stabilize the emulsions and the means of characterizing the oil–water interface and the emulsion films themselves. Some of the key unanswered questions surrounding the study of emulsion stability in petroleum systems are also reviewed.
