Magnitude of the impact test for spacecraft is generally required to be between 1000 g and 2000 g, moreover, the magnitude of some products is more than 3000 g. For high-magnitude impact test of large products, it is difficult for film impact test and drop impact test to meet the test requirements. In order to solve t…
Abstract In this work, the differences in nanomechanical properties, topography and morphology of carbonpalladium (C-Pd) films were studied. These films were prepared with a Physical Vapour Deposition method on various substrates with different technological parameters. We show that duration of the PVD process is a cr…
The objective of this research is improving the freeness of waste paper stock and paper quality by using the Cellulose Binding Domain (CBD) of endoglucanase Egl-II. CBD has been separated from endoglucanase Egl-II by proteolysis method. CBD has a molecular weight of approximately 21 kD. The produced CBD contained 0.04…
The continued use of fossil (petroleum-based) materials has raised environmental concerns due to their lack of bio-degradability and bio-sustainability. The coatings industry has been proactive by incorporating natural materials into its products. The recent thrust in favor of bio-based materials for coatings has led…
In diamond grinding cutting forces affect the quality of the machined surface. We can estimate a wear rate of the diamond wheel by the magnitude of the forces and promptly resort to the restoration of its cutting properties. To solve this problem it is necessary to define a relationship between grinding wheel wear and…
One of the progressive ways for increasing oral bioavailability of drug substances with poor solubility is nanoparticles preparation. Glibenclamide (Biopharmaceutical Classification System class II) was chosen as a model compound with low solubility and high permeability. Nanoparticles were prepared either by the anti…
We demonstrate microwave metamaterial with enhanced nonlinearity enabled by a significant mass and loss reduction due to perforated SU-8 substrate supporting self-rotating split ring resonators utilizing gravity as a restoring force. Forces involved in resonator movement are analyzed, and mechanical features of the st…
This paper explores new approaches in design and fabrication of novel composite materials in order to increase corrosion and wear resistance. By mimicking nature, nacreous particles from seashells were used as reinforcement in an aluminum matrix. A powder metallurgy process was developed to fabricate the nacreous-rein…
Purpose This paper aims to a newly designed photoresponsive four-armed graft copolymer was synthesised and characterised. The synthesised polymer contains photochemical group and a greater part of the cross-linkable functional group which is not affected by short wavelength when subject to under ultraviolet (UV) irrad…
The present study investigated the effect of changes in the milk fat globule membrane on the emulsion changes and flocculation of milk fat globules under the influence of saliva. Samples of raw and homogenized milk were examined. The flocculation process was characterized through computer image analysis of the emulsio…
Se han realizado varios estudios de la influencia de la orientación de la polarización en las características globales de los piezocompuestos. Extendiendo estas ideas, en el presente trabajo se estudia la influencia de la orientación de la magnetización en las características globales de un compuesto piezoeléctrico/pi…
Desiccant composites were prepared from seven high-impact polystyrene copolymers and two homopolymers (polystyrene, PS) to study the effect of structure and elastomer content on their functional and application properties. Composites containing an 4A type zeolite up to 50 vol % were homogenized in an internal mixer an…
This article reports on the temperature-controlled irreversible transition between the two isomeric forms of the strong electron acceptor dicyano- p -quinonediimine (DCNQI) on the Cu(100) surface. A combination of experiment (time-resolved, variable-temperature scanning tunneling microscopy, STM) and theory (density f…
Purpose The key purpose of this study was to investigate the effects of different ultrasonic irradiation times on the wettability and other properties of the resulting water-based coating. The subject water-based coating was prepared using water-soluble polyester and amino resins by ultrasonic oscillation. Design/meth…
Abstract Iron and nitrogen co-modified titanium dioxide nanocomposites, nFe,N-TiO2 (where n = 1, 5 and 10 wt% of Fe), were investigated by detailed dc susceptibility and magnetization measurements. Different kinds of magnetic interactions were evidenced depending essentially on iron loading of TiO2. The coexistence of…
Direct methanol fuel cells (DMFCs) are becoming a choice of a power source in the field of power electronics, and portable devices because of their high energy density. The benefits of using a fuel cell toward the environment will be enhanced if the fuel used for its application comes from renewable sources such as et…
La industria electrónica ha crecido en los últimos cincuenta años, sobre todo en los países desarrollados, contribuyendo a su progreso económico. Particularmente en el Estado de Baja California ubicada en el noroeste de México, estas empresas han prosperado en los parques industriales de Mexicali considerada como una…
Paper mill using recycle fiber as raw material produces reject containing fiber and plastic. The reject was identified by means of sorting. Reject pellet was prepared by drying, followed by shredding, and pellets molding. It was analyzed for its proximate composition (moisture, ash, volatile matter and fixed carbon).…
In this paper, a 3-D resistance model is proposed for phase-change (PC) memory cell based on cell geometry and RESET current. Explicit expression is developed for PC radius in terms of RESET current, cell geometry, and material property. Conformal mappings are used for SET and RESET resistance calculation in 2-D model…
Gels, microgels, and matrices were prepared based on a previously developed recombinant spidroin, 1F9, produced by Saccharomyces cerevisiae yeast strain; their physical, chemical, and biological properties were investigated. It was shown that microgels obtained from 2.5% hydrogel are sized in the range of 50–300 μm, w…
