In this paper, we introduce the Modelverse, a metamodelling framework and model repository. It clearly distinguishes and supports physical and linguistic conformance relations and allows for deep characterization and deep instantiation using potency. We introduce language fragments, which are reusable pieces of a language definition, consisting of an abstract syntax definition, as well as the d...

The self-assembled rosette nanotubes (RNT) are organic nanomaterials generated from the selfassembly of a bicyclic guanine-cytosine (GC motif) base. One of the advantages of these nanomaterials is the ability to tailor their function and properties by synthetically modifying the GC motif. Therefore, understanding the detailed supramolecular structure and arrangement of the RNTs with different f...

The objective of this study was to evaluate the influence of gelator, vegetable oil, stirring speed, and temperature on the physical properties of obtained organogels. They were prepared under varying independent conditions and applying a fractional experimental design. From there a rheological characterization was developed. The physical characterization also included polarized light microscop...

introduction: while little is known about the molecular mechanisms that establish the apical growth patterns in fungal mycelia, recent research on the genetics of a. nidulans and n. crassa has provided considerable amount information on some genes involving in polarised cell growth. a.nidulans is particularly amenable to experimental analysis and is importantly related to other human pathogen f...

two peroxidases (ec. 1.11.1.7), pod i and pod ii were purified from the roots of cultivatedraphanus sativus l. var. cicil by one step ion-exchange chromatography after fractionation by acetone. the molecular weight of these enzymes were 43000 and 41000 daltons and rz 1.2 and 2.0 for pod i and pod ii, respectively. both enzymes consisted of a single polypeptide chain on sds-page. the maximum act...

The thickness of silicon dioxide that is used as the transistor gate dielectric in most advanced memory and logic applications has decreased below 7 nm. Unfortunately, the accuracy and reproducibility of metrology used to measure gate dielectric thickness during manufacture of integrated circuits remains in some dispute. In addition, detailed materials characterization studies have resulted in ...

Successful organisms solve a myriad of problems in the face of profound physical constraints, and it is a challenge to quantify this functionality in a language that parallels our characterization of other physical systems. Strikingly, when we do this the performance of biological systems often approaches the limits set by basic physical principles. Here we describe our exploration of functiona...

Nowadays solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) have been investigated as carrier systems for many applications. SLNs consist of pure solid lipids, while NLCs are made of a solid matrix that entraps liquid lipid nano-compartments. These systems revealed several advantages compared to other colloidal carrier systems. They provide a controlled drug release and an ...

In the present work, we report the synthesis of binary nano metal oxides such as Zinc /Copper Oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. The synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦C. X...
