Two polymorphs of l-aspartic acid hydrochloride, C4H8NO4+Cl-, were obtained from the same aqueous solution.Their crystal structures have been determined from singlecrystal data collected at 100 K. The crystal structures revealed
three- and two-dimensional hydrogen-bonding networks forthe triclinic and orthorhombic polymorphs, respectively. The cations and anions are connected to one another...

The work presented in this paper revealed the effect of insulating (Al2O3) and semiconductive (TiO2) nanoparticles on green alternative insulating methyl ester oil synthesized from palm kernel oil. It also investigates the optimal concentration of the nanoparticle for dielectric improvement. The nanoparticle was functionalized with oleic acid before dispersion into the methyl ester to modify...

This work discloses the characteristics of a Bi2S3 nanowire / ITO photodiode and a manufacture method thereof; wherein, the high-crystalline Bi2S3 nanostructures were prepared by an environmental friendly dip-coating method onto Indium-doped Tin Oxide (ITO) coated glass substrates using bismuth nitrate and thiourea as raw material with DMF as solvent. The XRD spectra showed that the Bi2S3...

Il est toujours connu que les nanosatellites disposent de la plus petite taille de l’enveloppe, un coût bas, avec un temps de développement le plus court. En effet, c’est une nouvelle forme miniaturisée des satellites conventionnels et l’une des formes les plus recherchées.
Pourtant, ils font face à différents problèmes à savoir les gradients thermiques élevés ou les différentes charges...

Ferroelectric photovoltaics has been known for 50 years, it was not investigated extensively due to the low power conversion efficiency. Thus, we have very limited knowledge of ferroelectric materials and the underlying PV mechanism. Remarkably, recent research on the ferroelectric PV cells shows that engineered domain walls can exhibit a photovoltaic effect with an impressively high voltage...

Recent developments from the doping of two-dimensional (2D) monolayer MoS2 has opened up the possibility of scaling down the thickness of semiconductors channel field-effect transistors to the sub-nanometer scale. In order to realise efficient MoS2 based devices including p-n junction and field-effect-transistor for optimal performance, a controlled doping system needs to be fully understood....

Combining different polymers lead to a wide range of phase behavior. At rapid processing conditions (during preparation or flow), polymers are squeezed/deformed at various length scales and exhibit significantly different properties. The extent of deformation and the variation in properties depend on how the polymer responds to such rapid processing conditions and is related to the molecular...

A new hybrid graphene layer structure of the resonance of localized surface plasmon (LSPR), with silver nanoparticles (AgNPs) and substrate has been proposed to obtain a broadband absorption response for plasmon biosensors. The resonance peaks in the absorption spectra of the nanostructure SiOx/AgNPs/Graphene, demonstrate significantly different profiles such as the thickness of the graphene,...

Nanofluids are advanced kind of liquids or heat transfer fluids mixed with a small concentration of nanometer-sized solid particles in suspension. Nanofluids have broad applications in industries where efficient heat transfer fluids are crucial for cooling or heating processes. In addition, the shortage of fossil fuels motivated researchers to use alternative energy sources such as solar...

A growing interest in the development and use of small satellites in interplanetary missions with more up to date technologies is becoming a considerable option than large conventional satellites. Future development of these small satellites will require the application and use of passive thermochromic layers to achieve good thermal control for longer mission life and cost-effective launches....

The knowledge of the rheology of residues involved in dry digestion is an essential factor for process optimization. Despite this fact, it is difficult to characterize the rheological behaviour of these residues with high total solid (TS) content. Indeed, the standard methods of rheological measurements are poorly adapted to these residues because of the sliding effects observed during the...

Topological semi-metals are newly discovered states of quantum matter that have arisen interest
in the research community due to their application in spintronics and valleytronics. There are three
types of topological semi-metals (TSMs); Dirac Semi-metal (DSM), Weyl Semi-metal (WSM) and
Node Line Semi-metal (NLSM), each with special features that makes them novel candidates for
future...

EXTENDED ABSTRACT
(General) cosmology (GC) - the scientific study of the origin, evolution and eventual consequence of the universe – may be broadly and conveniently classified into two major parts. These are physical cosmology (PC) and mythological cosmology (MC) (otherwise known as religious mythology) (Peebles, 1993; https://en.wikipedia.org/wiki). There is no doubt that worldwide research...

The Pb(Zn1/3Nb2/3)O3-4.5PbTiO3 (PZN-4.5PT) single crystals showed very large ferroelectric and piezoelectric properties compared to traditional ferroelectric ceramics (BaTiO3 and PZT) used presently as active material in medical imaging, detection and sonars. However, despite these excellent properties, the greatest difficulty to use PZN-4.5PT single crystals on electronic devices is to...
