TL;DR: This Review focuses on recent strategies used to create semiconductor-metal hybrid nanoparticles, presents the emergent properties of these multicomponent materials, and discusses their potential applicability in different technologies.
Abstract: One key goal of nanocrystal research is the development of experimental methods to selectively control the composition and shape of nanocrystals over a wide range of material combinations. The ability to selectively arrange nanosized domains of metallic, semiconducting, and magnetic materials into a single hybrid nanoparticle offers an intriguing route to engineer nanomaterials with multiple functionalities or the enhanced properties of one domain. In this Review, we focus on recent strategies used to create semiconductor-metal hybrid nanoparticles, present the emergent properties of these multicomponent materials, and discuss their potential applicability in different technologies.

TL;DR: In this paper, the authors proposed a mechanism, applicable to AGN and nuclear starburst galaxies, in which there is accretion onto a supermassive black hole (SBH), which brings in gas from large to small scales by successive dynamical instabilities.
Abstract: A mechanism, applicable to AGN and nuclear starburst galaxies in which there is accretion onto a supermassive black hole (SBH), is proposed which brings in gas from large to small scales by successive dynamical instabilities. On the large scale, a stellar bar sweeps the interstellar medium into a gaseous disk a few hundred pc in radius. Under certain conditions, this disk can become unstable again, allowing material to flow inwards until turbulent viscous processes control angular-momentum transport. This flow pattern may feed viscosity-driven accretion flows around an SBH or lead to the formation of an SBH if none was present initially.

TL;DR: Investigation of the small subunit ribosomal RNA (16S-like rRNA) from the protozoan Giardia lamblia provided a new perspective on the evolution of nucleated cells and challenged the phylogenetic significance of multiple eukaryotic kingdoms.
Abstract: An analysis of the small subunit ribosomal RNA (16S-like rRNA) from the protozoan Giardia lamblia provided a new perspective on the evolution of nucleated cells. Evolutionary distances estimated from sequence comparisons between the 16S-like rRNAs of Giardia lamblia and other eukaryotes exceed similar estimates of evolutionary diversity between archaebacteria and eubacteria and challenge the phylogenetic significance of multiple eukaryotic kingdoms. The Giardia lamblia 16S-like rRNA has retained many of the features that may have been present in the common ancestor of eukaryotes and prokaryotes.

TL;DR: A hubris theory of entrepreneurship is developed to explain why so many new ventures are created in the shadow of high venture failure rates: more confident actors are moved to start ventures, and then act on such confidence when deciding how to allocate resources in their ventures.
Abstract: This paper develops a hubris theory of entrepreneurship to explain why so many new ventures are created in the shadow of high venture failure rates: More confident actors are moved to start ventures, and then act on such confidence when deciding how to allocate resources in their ventures. Building on theory and evidence from the behavioral decision-making literature, we describe how founders socially constructed confidence affects the manner in which they interpret information about their prior and current ventures. We then link founders propensity to be overconfident to their decisions to allocate, use, and attain resources. In our model, founders with greater socially constructed confidence tend to deprive their ventures of resources and resourcefulness and, therefore, increase the likelihood that their ventures will fail.
