“…compared to micro-particles. [8][9][10] By gel spinning fibrous structures of CuFe 2 O 4 could be prepared and subsequently loaded with Agnanoparticles to obtain high antibacterial magnetic fibres. 6 Formation of TiO 2 as surface layer and incorporation of copper as antimicrobial agent has been proposed to introduce antimicrobial surface properties on Ti-implants.…”

Copper(i)oxide microparticles – synthesis and antimicrobial finishing of textiles

Copper containing particles are of high interest to provide antibacterial activity to textiles for medical products, hygiene application or where odor formation as result of bacterial activity has to be controlled. Cu(I)oxide microparticles with a rather uniform diameter between 1.5 and 2 µ m can be prepared by controlled reduction of alkaline Cu(II)-tartaric acid complexes. Such particles can be bound to textile surfaces by means of a pigment binder system used in pigment dyeing. By a simple pad-dry process textile fabrics with a Cu-content of 250 -270 mg Cu / kg fabric could be prepared. The samples (fabrics) exhibited a reduction in viability of 100 % for Staphylococcus aureus and 84 % for Klebsiella pneumonia as estimated by the ASTM E2149 antimicrobial test. Simulated wash procedures led to a reduction in Cu-content to 60 -50 % of the initial value. Reduction in viability remained at 99 % for Staphylococcus aureus and 78 % for Klebsiella pneumoniae. The new process is of high value to impart antimicrobial properties to textile products because an antimicrobial product with good wash permanence can be delivered using rather simple processing and ordinary chemicals. Experimental Material and ChemicalsCopper(I)oxide microparticles were be bound to textile surfaces by means of a pigment binder system to provide antibacterial activity with good wash permanence, using rather simple processing and ordinary chemicals.

“…The mathematical formula is only a way of mathematical description. Due to the possibility of error, the linear function was used to describe the experimental data and given the very large adjustment (R 2 over 90%) [33], where: R 2 -coefficient of determination (it shows how well the data are fitted to a statistical model); R -linear correlation coefficient (it shows the strength and the direction of a linear relationship between two variables).…”

XPS analysis of nanolayer formed on AISI 304L SS after High-Voltage Electropolishing (HVEP)

Original scientific paper In the paper, a novel process named the High-Voltage Electropolishing (HVEP) is proposed to gain the specific surface properties on the treated metallic material. The AISI 304L stainless steel as the biomaterial was used for the HVEP treatment. Another feature of this work is using a concentrated phosphoric acid solution within the copper nitrate as electrolyte. The main purpose of the HVEP processing in that kind of electrolyte was to incorporate the copper ions into the passive surface film. Such a modified surface nanolayer was studied by means of the X-ray Photoelectron Spectroscopy (XPS) to reveal the composition of the obtained film. The comparison of the numerical results, dependent on the voltage applied, was performed. Moreover, the Cr/Fe and Cu/P ratios were determined to show the advantages of this electrochemical HVEP treatment. Keywords: AISI 304L SS; copper nitrate; High-Voltage Electropolishing (HVEP); phosphoric acid; XPS XPS analiza nano sloja nastalog na AISI 304L SS nakon elektropoliranja pod visokim naponom (HVEP)Izvorni znanstveni članak U radu se predlaže novi postupak nazvan elektropoliranje pod visokim naponom -High-Voltage Electropolishing (HVEP) kako bi se dobila specifična svojstva površine obrađivanog metalnog materijala. Za HVEP obradu kao biomaterijal korišten je AISI 304L nehrđajući čelik. Druga karakteristika ovoga rada je primjena koncentrirane otopine fosforne kiseline kao elektrolita u bakrovom nitratu. Osnovna svrha HVEP-a u toj vrsti elektrolita bila je uključivanje bakarnih iona u pasivni površinski sloj. Takav se modificirani nanosloj analizirao primjenom X-ray Photoelectron Spectroscopy (XPS) kako bi se otkrio sastav dobivenog sloja. Učinjena je usporedba numeričkih rezultata, ovisno o primijenjenom naponu. Uz to, određeni su omjeri Cr/Fe i Cu/P kako bi se pokazale prednosti tog elektrokemijskog HVEP postupka. Ključne riječi: AISI 304L SS; bakrov nitrat; elektropoliranje pod visokim naponom (HVEP); fosforna kiselina; XPS

“…The main disadvantage of plasma treatment is that it is an expensive process that must be carried out in a vacuum and may therefore be impractical for larger units of food processing equipment. Corona and flame treatments can impart similar functionality as plasma, are inexpensive, and can be used in a continuous operation; however, they are not as uniform or effective as plasma treatment (Chan 1993).…”

Emerging technologies in antimicrobial coatings can help improve the quality and safety of our food supply. The goal of this review is to survey the major classes of antimicrobial agents explored for use in coatings and to describe the principles behind coating processes. Technologies from a range of fields, including biomedical and textiles research, as well as current applications in food contact materials, are addressed, and the technical hurdles that must be overcome to enable commercial adaptation to food processing equipment are critically evaluated.
