Las nanopartículas de níquel han sido de gran interés en los últimos años por sus diversos campos de aplicación. En este trabajo se estudia la síntesis de nanopartículas de níquel metálico, cuando se emplea el proceso polyol. Mezclas de NiCl26H2O y NaOH disueltos en dietilenglicol (DEG) se sometieron a ebullición y ag…
El presente trabajo estudia un proceso de endurecimiento superficial a través de la formación de una capa boronitrurada sobre la superficie de un hierro puro. La selección del hierro puro es para evadir la influencia de algún elemento de aleación que modifique el crecimiento de las capas. Los procesos fueron llevados…
This paper studies multiaxial low cycle fatigue crack mode and failure life of Ti-6Al-4V. Stress controlled fatigue tests were carried out using a hollow cylinder specimen under multiaxial loadings of ?=0, 0.4, 0.5 and 1 of which stress ratio R=0 at room temperature. ? is a principal stress ratio and is defined as ?=s…

This paper suggests that chemical and metallurgical solid waste could be transformed into products through "addition" and "subtraction" processes, focusing on the "addition" and "reduction" methods and their common key process - crystallization process, as well as the control and function of metastable intermediates i…
The paper presents the comprehensive experimental study of radiation characteristics of a single slot in a coaxial cable shield. The slot was realized in four different embodiments, which varied by slot orientation and length. Three orthogonal polarizations of radiated electric field were analyzed along the axis perpe…
\nProduction of biodegradable polylactic acid (PLA) from biomassbased lactic acid is widely studied for substituting petro-based plastics or polymers. This study investigated PLA production from commercial lactic acid in a batch reactor by applying a direct melt polycondensation method with two kinds of catalyst, γ-a…
This paper aims to analyze the corrosion resistance of composite layers based on Ni-P matrix and disperse phase alumina of 10 µm size, present in amounts of 5, 10 and 20 g / L in the nickel plating bath. The influence of alumina on the corrosion resistance of Ni-P-Al2O3 composite layers was tested in 0.1 N hydrochlori…

The article presents preliminary assessment of the accident scale, level of its radiation effect on the population and response of national authorities of various countries for the population radiation protection provisions. High levels of the environmental radioactive contamination demanded the application of complex…

The heat fluxes impact on the road-dressing concrete surfacing under different regions climatic conditions of the construction and maintenance dramatically degrades their solidity, corroding-, shiftingand frost-resistance, and ultimately – the service durability. The source of deformation processes is the character of…
ABSTRACT A study was performed to evaluate the mechanical properties of solder of solder joints made to a 0.200Ti-4.0Cu-2.0Pt-0.25Au (μm) thin film conductor on low-temperature co-fired ceramic (LTCC) substrates. The solder joints were made with 63Sn-37Pb (wt.%, abbreviated Sn-Pb) or the 95.5Sn-3.9Ag-0.6Cu (SAC396) al…
This article presents a technique to create a model of shaping of the machined surface that takes into account: tool wear, dynamic system of the metal-cutting machine, cutting parameters, manufacturing errors and assembly errors of the metalcutting machine's drives.
ackground: One of the aims of food packaging is to protect the product from environmental factors that can cause a reduction in quality. Surface growth of microorganism is one of the leading causes of food spoilage. One option is to use antimicrobial packaging to provide an increased margin of safety and quality. Obje…
This study investigated the effect of pre-treatment and particle geometry/stratification on the physical and mechanical properties of cement-bonded particle boards (CBPBs). 6 mm thick homogeneous cement-bonded particle boards were made from Gmelina arborea roxb. sawdust and bambusa vulgaris shard. fibres with type 1 P…
