محققان آلماني روشي جديد براي توليد پوششهاي نانوكامپوزيتي پليمري - فلزي با خاصيت آنتيميكروبي ارائه دادند كه در آن نانوذرات طلا و نقره در لايه سطحي نازكي كنار هم قرار گرفتهاند. به گزارش سرويس «فنآوري» خبرگزاري دانشجويان ايران(ايسنا)، اين پوشش جديد خواص ميكروبكشي فوقالعادهاي از خود به نمايش گذاشته است. پتانسيل استفاده از پوششهاي سطحي آنتي ميكروبي باعث استفاده شايع آنها در صنايع مختلف مانند ساختمان و بستهبندي مواد غذايي و پزشكي كه آلودگيهاي موجود در ادوات تجهيزات آن موجب وارد آمدن زيانهاي هنگفت ميشود شده است. فيلمهاي نازك حاوي نقره اولين گزينههاي انتخابي براي اين منظور هستند. نقره به عنوان يكي از قديميترين عوامل ميكروبكش شناخته شده است. يونهاي نقره عامل بازدارندهاي در برابر آنزيمهاي باكتريها دارند و همچنين باعث جلوگيري از اتصال باكتريها به DNA ميشوند. نقره به صورت كاملاً مؤثر عليه باكتريها، قارچها و ويروسهاي مختلف مورد استفاده قرار ميگيرد. دكتر Vladimir Zaporojtchenko عضو هيأت علمي دانشگاه Kiel آلمان ميگويد: ما فرآيند جديدي را براي رسوب لايه نازك روي سطح ابداع كرديم كه سطح را در برابر رشد باكتريها مصون نگه ميدارد، اين فيلم نازك نانوكامپوزيتي داراي ذرات نقره درون يك ماتريكس فلوئوروپليمري ميباشد. با رسوب خوشههاي طلا درون لايه نازك، خاصيت ميكروبكشي نقره به شدت افزايش يافت. كارايي بالاي يونهاي نقره موجود در اين پوشش را ميتوان به تركيب خوشههاي نقره با خوشههاي نجيب طلا نسبت داد. تاكنون محصولات مبتني بر نقره جهت جلوگيري از نفوذ باكتريها مدنظر بودهاند. هر چند گاهي نتايج به دست آمده نااميد كننده يا كاملاً موفق بوده است. به گزارش ايسنا از ستاد ويژه توسعه فنآوري نانو، يونهاي نقره رايج مانند نيترات نقره در محيطهاي سيال زيستي به دليل تشكيل كمپكسهاي غيرفعال زيستي سريعاً غيرفعال ميشوند. روشهاي ديگر مانند بارورسازي نقره در حجم تودهيي، موجب ناكارامدي استفاده از ذرات نقره بارورشده گرانقيمت ميشود و از طرفي به دليل پراكندگي زياد مواد در حجم بالا كارآيي خاصيت ميكروبكشي آن كاهش مييابد، در نتيجه مقادير زيادي از نقره بدون استفاده ميماند. اين محققان توانستند با اين روش پوششهاي كامپوزيتي نازك با ضخامتهاي مختلف به دست آورند.

محققان استراليايي نخستين روكش ديوار ضدميكروب و ضدباكتري مبتني بر فنآوري نانو براي بيمارستانها را عرضه كردند.
به گزارش سرويس «فنآوري» خبرگزاري دانشجويان ايران(ايسنا)، اين محصول كه توسط شركتي در سيدني استراليا معرفي شده حتي ميتواند ميكروارگانيسمهايي مانند Staphylococcus Aureus يا MRSA را كه نسبت به آنتيبيوتيكها مقاوم ميباشند، از بين ببرد.
گفته ميشود، اين روكش جديد بر خلاف ساير رنگهاي ضدميكروب كه خاصيت ضد باكتريايي آنها پس از مدتي و با گذشت زمان از بين ميرود (از طريق تبخير مواد ضدميكروب)، حاوي نانوذراتي ميباشد كه در فاز جامد قرار دارند؛ بنابراين اثر خود را به طور ثابتي حفظ ميكند.
به علاوه، اين روكش به عنوان روكش عاري از نشر ماده شناخته شده و هيچگونه مادهاي را در فضاي دروني ساختمانها آزاد نميكند.
موسسه فنآوري شيميايي فرانهوفر آلمان به همراه Bioni Gmbh اين محصول را توسعه دادهاند كه نشاندهنده آخرين اكتشافات در زمينه فنآوري نانو و فنآوري روكشها ميباشد.
ميكروبها، باكتريها، و هاگهاي قارچهايي كه با اين روكش جديد و نانوذرات يكپارچه آن تماس پيدا كنند، به سرعت حذف ميشوند.
اثرات وسيع ايجاد شده توسط اين نانوروكش نه تنها باعث افزايش سطح بهداشتي در محيطهاي پزشكي و بيمارستاني ميشود، بلكه در حمامها، دستشوييها، محلهاي شستوشو و آشپزخانهها نيز موجب ايجاد بيشترين محافظت در برابر كپكزدگي و زنگ گياهي ميشود.
اثرات ضدباكتريايي Bioni Hygienic در آزمايشات وسيعي به اثبات رسيده است. كاهش ٦/٩٩ درصدي Staphylococcus Aureus قدرت اين روكش جديد را ثابت ميكند.
به گزارش ايسنا، با ظهور ابرارگانيسمهايي مانند Staphylococcus Aureus در بيمارستانها و ساير مراكز بهداشتي، مساله سطوح بهداشتي به يكي از بزرگترين نگرانيها در زمينه كاهش انتشار باكتريها تبديل شده است.
با وجودي كه در گذشته تميز كردن ساده تجهيزات و ابزارهاي جراحي مناسب به نظر ميآمد، اما اخيراً دريافتهاند كه ديوارها و سقفها اولين محل تكثير و رشد باكتريها ميباشند.
باكتريها به چندين روش مانند نشستن گرد و غبار و آئروسلهاي ريز، تماس با پوست انسان، و قطرات ريز مايع ميتوانند با ديوار تماس پيدا كنند. برخي باكتريها تا چند هفته و حتي چند ماه در اين محيط زنده ميمانند و حتي برخي هاگهاي باكتريها ميتوانند تا چند سال روي اين سطوح دوام بياورند.
تميز و بهداشتي نگه داشتن اين نواحي بايد يكي از اجزاي اصلي هر سيستم بهداشتي بيمارستاني باشد. به گزارش ستاد ويژه توسعه فنآوري نانو، به ويژه در بيمارستانها، درخواست بالايي براي مواد شيميايي و همچنين نيروي كار جهت تميز كردن ديوارها و روكشهاي داخلي وجود دارد.
اين محصول جديد - موسوم به Bioni Hygienic - براي پاسخگويي به اين خواسته طراحي شده است تا سطح بالايي از تميز بودن، ضدعفوني بودن، و حذف مواد شيميايي را ايجاد كند؛ به علاوه، اين روكش آتشزا نبوده و ايمني منحصر به فردي ايجاد ميكند.
Harry Stulajter مدير Nanovations Pty - شركت استراليايي سازنده اين نانوروكش - ميگويد: «Bioni Hygienuc بالاترين نيازمنديها و استانداردهاي بيمارستاني را تامين ميكند.
با وجود گزارشهايي كه نشان ميدهد ٦ درصد بيماران بستري در بيمارستان دچار نوعي آلودگي به نام عفونت بيمارستاني ميشوند و با تخمين South Australia كه نشان ميدهد هر عفونت بيمارستاني رقمي معادل ٢٢٠٠٠ دلار هزينه دربردارد (سالانه حدود ١٥٠ ميليون دلار)، مطمئناً براي چنين محصولي بازار خوبي وجود خواهد داشت. Bioni Hygienuc شرايط بهداشتي را در بيمارستانها و كلينيكها به ميزان زيادي بهبود خواهد بخشيد».
اين محصول نه تنها پنج سال گارانتي دارد، بلكه همراه آن فهرستي از نتايج آزمايشهاي انجام شده توسط مؤسسات معروف مستقل نيز ارسال ميشود.
At a groundbreaking conference on Nanotechnology held in South Africa on 19-20 April 2005, the Plasma Group of Peldev made several announcements regarding their technologies, capabilities and products.
Zircon Beneficiation
South Africa produces 350 000 tons/a of zircon (ZrSiO4), approximately 40% of the global demand. Very little is beneficiated locally and the majority is exported with little or no value addition.
Zircon is a very inert material and traditionally needs to undergo a high temperature alkaline melting processes to extract the valuable zirconia products from it. By using in-flight, non-transfer arc plasma technology, the zircon can be dissociated and made accessible for easy chemical processing. By using specialized plasma technology, such as the newly developed V-type plasmatrons, nano-zirconia products are manufactured in-situ in the plasma reactor.
Doped-Zircon Pigments
A unique, patented process for the manufacturing of inorganic doped-zircon pigments has been developed. This cost-effective process entails the dissociation of zircon through a high temperature non-transfer arc plasma to form a chemically reactive, plasma dissociated zircon (PDZ), which is suitable for use directly as feed stock for the manufacturing of Pr-yellow, V-blue and iron-coral zircon pigments. These pigments have been tested by various pigment manufacturers and by an independent international research laboratory. The results compare very favorably with the best pigments commercially available.
Superior Zircon opacifier
A patented process has been developed to upgrade an inferior grade of zircon to a superior opacifier for ceramic applications by means of a calcining process in the presence of selected mineralizers. This process results in a substantial improvement in the opacifying properties of an inferior grade of zircon compared to that of prime grade zircon that is currently being used commercially in the ceramic industry.
Nano Materials
Nano-titania (TiO2) is now used extensively in sunscreens, cosmetic products, pharmaceuticals, and in paints. The titania materials can now be manufactured by means of a high temperature plasma torch, using titanium tetrachloride (TiCl4) as feedstock.
The plasma process is environmental friendly, in the sense that zero effluent is produced as all the chloride is recovered as chlorine gas which is recycled to the chlorination process to produce TiCl4 from illmenite or rutile sand. The particle size of the plasma titania is sub-micron and the plasma parameters can be manipulated to produce nano-titania.
Pyrogenic silica, or fumed silica, with special properties like high specific surface area, nano particle size, hydrophobic or hydrophilic in nature, is synthesized in a plasma reactor from silicon tetrachloride (SiCl4). SiCl4 is a byproduct emanating from the carbo-chlorination of zircon sand. With the plasma process, this waste product is transformed into a high value product that is used in specialized silicon polymers, pharmaceuticals, food, etc.
Other nano particle size products can also be manufactured by utilizing plasma technology. These include nano alumina, nano zinc oxide, carbides, borides and nitrides.
Microbian evolution on a wide variety of surfaces can produce phenomena such as corrosion, dirt, smells and even serious hygiene and health problems.
It is well known there is a great interest in the design and development of the so-called “hygienic surfaces”, referring to surfaces that not only provides biocidal activity but also to those that are easy to clean and even self-cleaning.
Achieving these properties on a surface is possible by means of coatings and treatments on specific surfaces, and in which nanotechnology plays a key role. Most of these coatings acquire their biocidal/self-cleaning capacity by incorporating specific nanoparticles: basically silver (Ag) and titanium oxide (TiO2).
The development of these coatings is key mainly in sectors such as architecture and construction, textiles, heat exchangers, air conditioning circuits, hygiene-health (hospitals, schools) and food processing.
The achievement of such coatings means, not only a reduction in the problems of corrosion and in health risks, but also a reduction or elimination in the consumption of biocides and toxic industrial detergents.
Various methods and technologies currently exist that enable the obtaining of these biocidal surfaces, amongst which are the incorporation of nanoparticles in organic resins (in ceramic matrixes), as well as the deposition in plasma-vacuum with incorporation of nanoparticles.
An INASMET-Tecnalia research team has led the proposal for the project known as “Development and evaluation of coatings and surface conditions on steel for antibacterial and easy-to-clean properties, DECOBIOF”. The aim is to design, develop and evaluate those surfaces with antibacterial and self-cleaning properties.
Apart from the participation of the Technological Centre, co-ordinator of the project, el the consortium is made up of CORUS UK Limited (UK), the Max Planck Institute (Germany), OCAS-Arce-lor N.V. (Belgium), SIMR (Sweden), ACERINOX (Spain) and the Centro Sviluppo Materiali (Italy).

Nanohorizons Release Silver and Gold Antimicrobial Nanoparticles for Consumer Applications NanoHorizons, Inc. today announced the availability of a low-cost line of concentrated, polymer-compatible gold and silver nanoparticles in research and pilot production volumes. With prices for small quantities ranging from $100 to $400 per liter, NanoHorizons’ noble-metal nanoparticles’ unique combination of exceptionally low cost and polymer manufacturing process compatibility will enable manufacturers to create a vast array of plastic consumer and industrial products with built-in antimicrobial properties. Examples of potential products include plastic storage containers, food packaging materials, plastic gloves, and clothing such as odor-free, microbial-free shoes, socks, and hats. From Odorless Shoes to Extended Shelf Life for Perishable Products “Our manufacturing process advantages enable us to price our nanoparticles aggressively - 90% below the lowest competitive price we could find - and offer them in a choice of solvents, making them easily adaptable to current manufacturing processes,” said Robert Burlinson, CEO and President of NanoHorizons. “This means that all sorts of manufacturers can easily and inexpensively incorporate the attractive properties of noble metals into their products. Imagine shoes or socks that are odor-resistant, mascara that resists transmitting infections, and food packaging materials that increase food storage life on the shelf or in the home.” Silver: An Antimicrobial Since Antiquity Silver’s antimicrobial properties have been known for centuries. In ancient Greece and Rome, silver containers were used for perishable liquids because they retarded the growth of food-spoiling organisms. Western medicine has been using eye-drops containing silver to prevent infections in newborn babies’ eyes for more than a century. More recently, silver has been introduced into socks to prevent foot infections for soldiers deployed in jungles.
“While silver has been used since antiquity for its antimicrobial properties, these are the first commercially available noble metal nanoparticles engineered for use in plastic-based products, making them economically viable for innumerable products and applications,” said Dr. Stephen Fonash, NanoHorizons’ Chairman. “These particles are terminated with specific surface chemistries and delivered in organic solvents, making them compatible with polymer processing. This breakthrough brings together three critical components: noble-metal nanoparticles, volume commercial availability at breakthrough costs, and compatibility with polymer processing. Pricing NanoHorizons’ silver and gold nanoparticles are available immediately at prices ranging from $100/liter (non-functionalized, in water) to $400/liter (Carboxylic acid or Amine functionalized in water, Methanol or Ethanol). NanoHorizons Gold nanoparticles are 10-30 nanometers(nm) in size; silver nanoparticles are offered in two particle sizes: 10-30nm and 49-90nm. Available surface terminations include Amine, Carboxylic Acid, or Methyl and are delivered in a choice of two organic solvents: methanol and ethanol. They are also available in water.
