Redox states of soda lime glass melts have been widely studied by using variations of oxidizing and colorizing agents. In physical decolorizing process, the clear white glassware can be obtained by controlling the suitable amount and type of both oxidizing and colorizing agents in the batch formula. Erbium oxide (Er2O…
Abstract Unglaublich dünn, gleichzeitig fest und leitfähig − die wissenschaftliche Welt feierte die zweidimensionale Kohlenstoffmodifikation nach der Entdeckung Anfang der 2000er Jahre als neues Wundermaterial. Inzwischen hat die Begeisterung etwas nachgelassen – aber verebbt ist sie noch nicht.
The inside cover picture shows a schematic idea of the concept of degeneracy reprogramming. Mutating a given protein with non-proteinogenic amino acid (NAA) has become an invaluable tool in protein engineering. Incorporating a NAA is usually accomplished by reprogramming one of the stop codons, so frequently, multiple…

Kenaf bast fibers were prepared into two types as untreated and maleic anhydride (MA) treated. Unsaturated polyester (UPE) resin was used as matrix and applied onto the kenaf bast fibers using hand lay-up method. Transverse and longitudinal flexural properties of unidirectional long kenaf bast fiber reinforced unsatur…
Monazite (LaPO4) coatings were deposited on woven cloths of alumina fibers by heterogeneous nucleation and growth using solution precursors. Coatings were characterized by scanning electron microscopy, and X-Ray diffraction; thermogravimetric analysis was performed on LaPO4 precursors. The results show that the optimu…
Polysilicon layers acting as an absorption layer in a metal-semiconductor-metal (MSM) photodetector were post-annealed with various annealing processes to find the relationship between the morphology of polysilicon and the photo-response of the MSM photodetector. Among the processes, rapid thermal anneal (RTA) was a s…
Si3N4 (0 and 6 mass%) were added to Al-Al2O3 composite respectively, with phenolic resin as binder, to make Al-Si3N4-Al2O3 unfired composites, which were dried at 200°C for 24h.The creep properties of composites were tested researched under 0.2MPa×50h at 1300°C. The results indicated that the samples put up the featur…
Motivation One of the fundamental issues in both chemistry and biology is the identification of the structural determinants that dictate protein folding and stability. The decoding of the folding code of protein structures would have a major impact on native structure prediction and on de novo design. This task is par…
Ling Liu and co-workers demonstrate that Hydrogen bonds serve as “thermal bridges” that effectively conduct heat between two materials of drastically different thermal properties in article 1600211. By covalently functionalizing graphene with hydroxyl groups, thermal conductance across the graphene/poly(methyl methacr…
The influence of beta radiation on the changes in the structure and selected properties (mechanical and thermal) polymers were proved. The use of low doses of beta radiation for polypropylene and its influence on the changes of micro, macro mechanical properties was thoroughly studied. The specimens of polypropylene w…
In this paper, a series of YSZ/NiZn ferrite composites with seven varying volume fractions of NiZn ferrite (0 vol%, 20 vol%, 40 vol%, 50 vol%, 60 vol%, 80 vol% and 100 vol %) were prepared. The complex permeability of the composites was measured in frequency range from 1 MHz to 100MHz and the effect of the composition…
The objective of this research is to investigate the effect of the annealing process on the mechanical and electrical properties of thermoplastic polyurethane/multi-walled carbon nanotube (TPU/MWCNT) nanocomposites. The TPU/MWCNT nanocomposites were prepared by melt-mixing the TPU with 1, 3, and 5 wt.% MWCNT. The TPU/…
There is a rising demand to substitute fossil fuels with environmental-friendly energy resources. Providing hydrogen resource through a water splitting process can be one way to satisfy this critical need. The high cost of the conventional water splitting catalysts such as platinum makes this process inapplicable for…
Special-effect finishes are used in many applications to create new color impressions, pronouncing the design of a product and at the same time making the product appear alive. Total appearance conducting color and geometrical factors such as gloss, shape, etc. Gloss is an attribute of visual appearance that originate…
The present work has the purpose to study and to evaluate the corrosion resistance of zinc layers and phenol – formaldehyde resin/Zn composite layers obtained by electrodeposition. For the best results it was used different parameters for electrodeposition such as: current density between 3 – 5 A/dm2, time for electro…
The cover picture shows, in a symbolized manner, the two elemental processes that occur during the metal-templated macrocyclization of linear tetrapyrroles: the locking of a pseudomacrocyclic conformation and the induced cyclization by coupling of the tetrapyrrole termini. Isocorroles are new members of the porphyrino…
The operational degradation of surface layers due to a rolling contact process was simulated for Hadfield steel by a special testing rig. A specific limited state based on cumulative depletion of plasticity was achieved.Precise evaluation of the surface layer's mechanical parameters is necessary for a service life pre…
An experimental study of buckministerfullerene on the Au(111) surface and of chlorobenzene and oxygen molecules on the Si(111)-7x7 surface has been conducted with variable and room temperature (RT) scanning tunneling microscopes, respectively. First, the formation of hybrid clusters, (C\(_{60}\))\(_n\)-(Au)\(_m\), fro…
The Co element was used during the first operation of high temperature reactor (HTR) reactor to distinguish low-enrichment and high-enrichment fuel elements. In this paper the YSZ/CoO ceramic tracer microspheres with YSZ coating were prepared. The design size of the microspheres were about 750μm. The YSZ shell thickne…
