'Nikola Dordevic' 'Weyde M. M. Lin' 'Olesya Yarema' 'Vanessa Wood'] Engineering the compositional gradient for core/shell semiconductor nanocrystals improves their optical properties. To date, however, the structure of graded core/shell nanocrystal emitters has only been qualitatively described. In this paper, we…

'Xiaoshuang Chen' 'Giorgio Biasiol'] The electronic properties of zincblende ZnSe/Si core-shell nanowires (NWs) with a diameter of 1.1-2.8 nm are calculated by means of the first principle calculation. Band gaps of both ZnSe-core/Si-shell and Si-core/ZnSe-shell NWs are much smaller than those of pure ZnSe or Si NWs.…

Over the past two decades, nanostructured materials, especially semiconductor heterostructures, have been major contributions to advance nanotechnology [1,2]. There has been a particularly growing interest in nanowires (NWs) research [3,4], as semiconductor NWs have emerged as versatile building blocks for nanoscale…

This report of the reddest emitting indium phosphide quantum dots (InP QDs) to date demonstrates tunable, near infrared (NIR) photoluminescence and fluorescence multiplexing in the first optical tissue window with a material that avoids toxic constituents. This synthesis overcomes the InP synthesis “growth bottleneck”…

'Milan Pejić' 'Peter A. van Aken' 'Branko Matović' 'J. Christian Schön' 'Carmen Canevali'] ZnO/ZnS core/shell nanostructures, which are studied for diverse possible applications, ranging from semiconductors, photovoltaics, and light-emitting diodes (LED), to solar cells, infrared detectors, and thermoelectrics, were…

Amorphous Selenium Nanoparticles (α-SeNPs) exist in a metastable state of polymeric Se8 rings and Sen chains that break and reform by electron propagation. Here we show that this quality can underlie the formation of metal selenide nanoparticles (MSeNPs) via a disproportionation type reaction with metal salt…

In this contribution, porous hollow silica nanoparticles using inorganic nanosized ZnS as a template were prepared. The hydrothermal method was used to synthesize pure ZnS nanospheres material. The ZnS@SiO2 core-shell nanocomposites were prepared using a simple sol-gel method successfully. The hollow silica…

The discovery of layered materials with potentially unique electrical and chemical properties has become a major focus of materials research in the past decade. II-VI layered hybrids (LHs) are a family of ligand-protected layered materials capable of isolation in few-layer form and possess emissive and electronic…

Plasmonic materials, such as gold nanoparticles (AuNPs), exhibit significant extinction and near-field enhancement across the visible and near-infrared spectrum, attributable to localized surface plasmon resonances (LSPRs). Epsilon-near-zero (ENZ) materials, such as aluminum doped zinc oxide (AZO) are known in…

Carboxysomes are proteinaceous organelles featuring icosahedral protein shells that enclose the carbon-fixing enzymes, Rubisco, alone with carbonic anhydrase. The intrinsically disordered scaffolding protein CsoS2 plays a vital role in the construction of α-carboxysomes through bridging the shell and cargo enzymes. The…

'A. Martynov' 'T. Haga' 'D. L. Distel' 'Donald James Colgan'] The sea-grass borer Zachsia zenkewitschi belongs to a group of economically and ecologically important bivalves, commonly referred to as shipworms. The sole recognized representative of the genus Zachsia, this species displays an unusual life history and…

In this article, we present a Shell Language Preprocessing (SLP) library, which implements tokenization and encoding directed on parsing of Unix and Linux shell commands. We describe the rationale behind the need for a new approach with specific examples when conventional Natural Language Processing (NLP) pipelines…

The Linux shell is arguably one of the most important computational tools across various scientific disciplines. Its high flexibility makes it the platform of choice for many file operations and smaller scripting tasks. Also, many stand-alone programs are called from the Linux shell - typically followed by multiple…

AbstractThe present study aims to clarify the confused taxonomy of Z.schaufussi von Frauenfeld, 1862 and Zospeumsuarezi Gittenberger, 1980. Revision of Iberian Zospeum micro snails is severely hindered by uncertainties regarding the identity of the oldest Iberian Zospeum species, Z.schaufussi von Frauenfeld, 1862. In…

A careful design of nanocrystal architecture can strongly enhance the nanocrystal function. So far, this strategy faced a synthetic bottleneck in the case of refractory oxides. Here, we demonstrate the epitaxial growth of hafnia shells onto zirconia cores, and pure zirconia shells onto europium doped zirconia cores.…

Building on prior mathematical formulations of the periodic law, this paper demonstrates that the algebraic formula S(k) = 2 * (floor(k/2) + 1)^2 accurately predicts the period lengths (2, 8, 8, 18, 18, 32, ...) of the periodic table. This pattern is not a numerical coincidence but a direct consequence of the…

'Puchao Zhang'] Abstract—In IT system operations, shell commands are common command line tools used by site reliability engineers (SREs) for daily tasks, such as system configuration, package deployment, and performance optimization. The efficiency in their execution has a crucial business impact since shell commands…
