Paramagnetic nanoparticles in stem cell therapy
In recent years metal oxide nanoparticles have become a useful tool in biomedicine. They are used as contrast agents for magnetic resonance imaging, carriers in drug delivery, compounds for hyperthermia cancer treatment or targets for cell tracking and guiding mechanisms. Even though recent advances bring stem cell th…
Characterizing the role of the Early Gene at 23 (E23) in Drosophila Melanogaster Oogenesis
Drosophila melanogaster (fruit fly) females undergo oogenesis to create oocytes from undifferentiated stem cells in the ovary. Similar to estrogen in humans, the steroid hormone ecdysone in fruit flies has a known role in facilitating oogenesis. The ecdysone signaling pathway is highly studied as it can help us draw p…
Diffusion characterization of antimony-based type-II superlattices using electron beam induced current and time-resolved photoluminescence
The infrared wavelength range is of vital importance for thermal imaging, molecular sensing, astronomy, and a variety of other health, medicine, and security and defense applications. Infrared detectors, capable of light detection in this vital wavelength range are thus of significant technological importance. In the…

Corrélations électroniques des acènes vers la limite de longue taille : étude par Monte Carlo quantique
We study the family of acenes by means of quantum Monte Carlo methods (QMC) based on a Jastrow correlated antisymmetrized geminal power (JAGP) wave function. Those methods allows for JAGP optimization in a variational manner (energy minimisation) and for ground state energy evaluations when the wave function nodes are…
Influence of Drying Duration of Paving Block with the 5% Fly Ash Addition on Compressive Strength (Water Binder)
This study was conducted to determine the effect of variations in drying time with the addition of 5% by weight of fly ash in the manufacture of paving blocks through compressive strength testing. Fly ash is derived from the combustion of coal in a steam power plant of Sijantang Sawahlunto. The increase of production…
Untersuchungen zur Steuerung des Kristallisationsverhaltens von Aminosäuren in Lösung durch den Einsatz von Deuterium oder Biomineralien
Im Zusammenspiel aus unterschiedlichen Methoden, wurde das Polymorphieverhalten von Glycin und die Enantiomerentrennung von DL-Prolin untersucht. Hierbei lag der Fokus auf möglichen Einflüssen durch den Isotopenaustausch von Wasserstoff gegen Deuterium und die Effekte, die die Adsorption an biomineralischen Oberfläche…

Continuous Silicate Utilization Over 14L:10D Day:Night Cycle Confirms Night Metabolism in Lake Michigan Diatom Enrichments Using Either Nitrate or Ammonium as a Nitrogen Source
Diatoms are single-celled organelle containing eukaryotes living in “glass houses”. As diatoms only take up silica when they replicate, measuring the amounts of dissolved and particulate silicate were an important aspect of this study. Silica was used as a proxy of the diatom reproduction. Depending on growth conditio…
Performance comparison between a prism and diffraction grating in a low-cost spectrometer
Optical spectroscopy is a very important branch of chemistry; it can be used for the quantitative analysis of chemical specimen, but also provides a detailed view of the structure and behavior of chemical systems.When using fluorescence spectroscopy on weakly emitting samples, a very sensitive spectrometer must be use…
Effect of channel angle on the material flow and hardness distribution during incremental ECAP of Al-1050 billets
Incremental equal channel angular pressing (I-ECAP) is an extension of the classical ECAP method used to produce ultrafine grained (UFG) metals. This paper investigates the first pass of I-ECAP performed on AA-1050 billets measuring 10x10x60mm and the effects of processing with two different dies with the channel inte…
Cellular Automata Associated to Finite Groups
The purpose of this research is to study a type of dynamical system called a “cellular automaton” (CA) and to investigate a family of one-dimensional cellular automata associated with a finite group of symmetries. We aim to analyze the large scale structural statistics of these systems in order to gain insight about t…
Optimization of Magnetostrictive Nanocellulose Composites
Terfenol-D, first synthesized in the 1970s, exhibits the highest magnetostrictive properties of all alloys. It is costly to produce and difficult to machine. It also exhibits low ductility and tensile strength. Terfenol-D particles can be integrated into a composite in order to reduce manufacturing cost, while still p…
Ferroelectrics Manipulate Magnetic Bloch Skyrmions in a Composite Bilayer
Theoretical investigation demonstrates that the composite bilayer (i.e., chiral-magnetic/ferroelectric bilayer) offers the possibility of electric-induced magnetic Skyrmions [Phys. Rev. B \textbf{94}, 014311 (2016)]. In this Article, we propose a micromagnetic model to physically manipulate magnetic Bloch Skyrmions pr…
