New diamond-like carbon nitrides (C–N heterodiamonds), no less hard than diamond, have been synthesized for the first time in bulk form by shock compression of graphitic carbon nitride precursors in the dynamic pressure–temperature range around 30 GPa–3000 K. Typically, the C2N heterodiamond obtained from graphitic C3…
The article presents a review of the theory of reliability and its use for design code making procedures based on the probabilistic approach. Principles of structural safety in design code making are considered. To do so, the basic principles of the limit state methods in the form of partial factors and ways of their…
Microporous poly(D,L-lactide-co-glycolide) matrices containing encapsulated proteins were fabricated in a solvent-free manner. Microporous foam was generated by saturating a mixture of polymer and protein particles in supercritical carbon dioxide (SC-CO2), dispersing the protein particles in the polymer melt followed…
Polylactides and their copolymers are key biodegradable polymers used widely in biomedical, pharmaceutical and ecological applications. The development of synthetic pathways and catalyst/initiator systems to produce pre-designed polylactides, as well as the fundamental understanding of the polymerization reactions, ha…
The need for this book arose from my teaching, engineering, and - search experience in the non-power aspects of nuclear technology. The lack of a comprehensive textbook in industrial applications of radiation frustrated my students, who had to resort to a multitude of textbooks and research publications to familiarize…

The adhesion of plated metal layers to epoxy polymer surfaces is of prime importance for the reliability of electronic interconnections. An increase in the roughness of the polymer surface, caused by chemical treatment, strengthens adhesion by increasing the total area of interaction between both layers. The evolution…
The physico-chemical properties of the natural diatomite, mined in the Lampang Province of Thailand, and the treated diatomite were studied. There included the composition analysis, phase analysis, morphology, thermal analysis, and particle size analysis. The results showed that the natural diatomite was composed of m…
Collagen is often used in bioartificial livers as a biomimetic coating to promote liver cell adhesion and differentiation. Animal proteins are expensive and expose the host to risks of cross-species infection due to contamination with prions. Silk fibroin (SF) is a biocompatible protein produced by Bombyx mori silk wo…
The synthesis of the new polynucleating ligand 1,3-bis-(3-oxo-3-(2-hydroxyphenyl)-propionyl)-benzene (H4L) is reported along with the preparation, structure and properties of its dinuclear complexes [Cu(2)(H(2)L)(2)(py)(2)](1), [Ni(2)(H(2)L)(2)(py)(4)](2), [Mn(2)(H(2)L)(2)(dmf)(4)](3), [Co(2)(H(2)L)(2)(dmf)(4)](4) and…
This paper contains a review of basic research and new concepts in flax and hemp fibre processing for flax and hemp cotton-like and wool-like yarns spun by different spinning systems. The review covers the trends and economical conditions since the beginning of the 20th century. We present the advantages and disadvant…
It has been acknowledged that ultrasonic impact treatment (UIT) occupies a firm position among methods for improving the reliability of welded joints, particularly their fatigue strengths. Developed in Russia in the early 1970s, this process has aroused considerable interest among experts and researchers in the area o…
The preparation of SBA-15 type plugged mesoporous silica using an inexpensive silica source in a two-step process is described. The resulting material was used as a catalyst support for a hydrodechlorination (HDC) reaction. The structure and morphology of the mesoporous silica and catalysts were determined using trasm…
The redox active ligand EDT-TTF-CONH-3-pyridine undergoes a [2 + 2] cycloaddition upon irradiation with polychromatic light, an unprecedented single-crystal-to-single-crystal transformation for a TTF derivative.
Magnetic Barkhausen noise measurements have been carried out to characterize Ferrite-Martensite steels. Using thermal treatments, the volume fraction and the carbon content of martensite were varied in reasonable proportions. The results indicate that the Barkhausen noise measurements can easily allows us to distingui…
The reaction of a series of phosphanyl-terminated carbosilane dendrimers displaying only one phosphorus ligand per arm with [RuCl(2)(p-cymene)](2) resulted in the grafting of RuCl(p-cymene) moieties on the periphery of the dendrimer. In these species, the chloride ligand is easily displaced by the organic bases pyridi…
Nearly monodispersed tin/tin oxide core/shell nanoparticles were prepared by a reverse microemulsion technique. A phenanthroline–tin chloride complex was used in an optimized microemulsion system to obtain small particle size and good size control (mean = 3.2 nm, standard deviation = 0.5 nm). Preparation in the absenc…
Freestanding anodic aluminum oxide (AAO) membranes were fabricated using a two-step anodization procedure, voltage reduction method, and inductively coupled plasma polymerization. The fabrication process was monitored with electrochemical and spectroscopic ellipsometry measurements, X-ray photoelectron spectroscopy, F…
Abstract Hartree–Fock (HF) and density functional (DFT) LCAO calculations of single (2D) and periodical (3D) slab models of MgO crystal are presented. HF and DFT methods produce very close results for the surface energy and electrostatic potential and exhibit the same convergence properties, with the slab thickness in…
We propose a new method for the kinetic treatment of self-discharge of intercalation electrodes based on a combination of cyclic voltammetry (CV) and chronopotentiometry under net zero current conditions. This was applied to composite graphite electrodes in 1 M dimethyl polycarbonate at four different temperatures fro…
