INTRODUCTION: Biocompatible mesoporous silica nanoparticles (MSNs) are regarded as one of the most promising inorganic drug delivery systems (DDSs) to concurrently enhance the therapeutic efficiency and mitigate the side effects of anticancer drugs. Elaborately combining multicomponents with MSNs will endow them with…
A material is said to be flexoelectric when it polarizes in response to strain gradients. The phenomenon is well known in liquid crystals and biomembranes but has received less attention in hard materials such as ceramics. Here we derive the governing equations for a flexoelectric solid under small deformation. We ass…
Artificial superlattice nanocomposites are successfully prepared by electrostatic heteroassembly of redoxable Co-Al or Co-Ni layered double hydroxide (LDH) nanosheets with graphene. The superlattice electrodes exhibit a high capacity up to ca. 650 F/g, which is approximately 6 times that of pure graphene. The composit…
Electric-field-controlled tunneling magnetoresistance (TMR) of magnetic tunnel junctions is considered as the milestone of ultralow power spintronic devices. Here, reversible, continuous magnetization rotation and manipulation is reported for TMR at room temperature in CoFeB/AlOx/CoFeB/piezoelectric structure by elect…
ABSTRACT Cellulosic nanoparticles with high Young's modulus, crystallinity, specific surface area, and aspect ratio can be found in the natural structure of plant fibers. Indeed, lignocellulosic fibers consist of semicrystalline cellulose nanofibrils embedded in an amorphous matrix mainly composed of lignin and hemice…
Hybrid nanostructures composed of semiconductor and plasmonic metal components are receiving extensive attention. They display extraordinary optical characteristics that are derived from the simultaneous existence and close conjunction of localized surface plasmon resonance and semiconduction, as well as the synergist…
La Polymerisation Radicalaire par Ouverture de Cycle (R-ROP) est une methode de synthese de polymeres contenant des fonctions chimiques de choix dans le squelette carbone grâce a un mecanisme d'addition-fragmentation. L'utilisation de monomeres specifiques, les Acetals Cetenes Cycliques (CKA), permet dans certaines co…
La Polymérisation Radicalaire par Ouverture de Cycle (R-ROP) est une méthode de synthèse de polymères contenant des fonctions chimiques de choix dans le squelette carboné grâce à un mécanisme d'addition-fragmentation. L'utilisation de monomères spécifiques, les Acétals Cétènes Cycliques (CKA), permet dans certaines co…
Herein, we demonstrate that a perfect replication of a desired composition is not only related to the degree of interconnectivity of the double gyroid ordered mesoporous silica template, there is also an enormous effect from the nature of precursor and its composition. For the first time, the symmetry of ordered mesop…
Des produits de consommation de première nécessité aux produits les plus fortuits, l'emballage, en particulier plastique, constitue aujourd'hui un élément indispensable de notre vie quotidienne. Son utilisation intensive dans le domaine agroalimentaire pour un usage unique à courte durée de vie incite aujourd'hui à s'…
The present paper is devoted to the study of classes of mappings with\nnon-bounded characteristic of quasiconformality. It is obtained a result on\nnormal families of the open discrete mappings $f:D\\rightarrow {\\Bbb\nC}\\setminus\\{a, b\\}$ of the class $W_{loc}^{1, 1}$ having a finite distortion\nand omitting two f…
We study the propagation of light in a three-dimensional double-periodic\nAg/TiO2 multilayer metamaterial composed of coupled plasmonic waveguides\noperating in the visible and UV spectral range. For these frequencies, light\npropagation in the plane of the waveguides is described by a negative phase\nvelocity, while…
Industrial production of the detergent enzymes takes place in fermenters 40–125 m3 in size by Bacillus licheniformis. Without the use of specific enzymes and specially tailored enzyme mixtures, the high performance of modern detergents would be not feasible.
The production of granules from powdered solids takes place in dry conditions under pressure or with the addition of liquids with subsequent drying/cooling. These processes are well established in industry worldwide.

In chemical conversions, the raw materials and the synthesis route as well as the chemical reactor(s) with the appropriate operating conditions influence the product design. The product quality depends in particular on the removal of reaction heat and the residence time distribution.

In extraction and processing of materials from natural resources, reactions between ground raw materials and fluid media (gases, liquids) occur. In model ideas (“shrinking core”), the starting particles shrink during reaction, shown in several examples from practice.

In the past 50 years, powdery and granular detergents have improved significantly in performance and ecology. The production of solid detergents expires in spray towers either without or with a compaction step and in “non-tower” agglomeration plants. Latest generation of granulation allows the production of spherical…
