Abstract
Epoxy resin nanocomposites were prepared by curing bisphenol-F with an aliphatic amine in the presence of SiO2 and ZrO2 nanoparticles as inorganic fillers. Both types of particles were prepared with diameters of around 10 nm and 70 nm to study size effects in the nanocomposites. The nanoparticles showed a different constitution: while silica was amorphous and spherical in nature, zirconia was crystalline and non-spherical. Both nanoparticles were surface-functionalized with novel diethylene-glycol-based capping agents to increase the compatibility with the epoxy matrix. The organic functionalities were attached to the nanoparticle surface via phosphonic acid (zirconia) and trialkoxysilane (silica) anchor groups. The homogeneity of the distribution of surface-modified inorganic nano-sized fillers in the matrix up to 5.8 vol% in case of silica and 2.34 vol% in case of zirconia was determined by small-angle X-ray scattering and transmission electron microscopy. Mechanical properties such as hardness and storage modulus were increased with increasing filler content while thermal stability of the obtained materials was nearly unaffected after incorporation of nanoparticles.

Study of the effect of the concentration, size and surface chemistry of zirconia and silica nanoparticle fillers within an epoxy resin on the bulk properties of the resulting nanocomposites
Epoxy resin nanocomposites were prepared by curing bisphenol‐F with an aliphatic amine in the presence of SiO2 and ZrO2 nanoparticles as inorganic fillers. Both types of particles were prepared with...Ionic polymers with tunable liquid‐crystalline properties
Side‐chain polyesters were synthesized from N‐octyl‐, N‐dodecyl‐ or N‐hexadecyl‐diethanolamine and succinic acid anhydride. These polyesters were then transformed into polyester hydrochlorides by...Influence of medium on the nanostructure and properties of poly(4‐aminodiphenylamine)‐silver nanocomposites
Poly(4‐aminodiphenylamine)‐silver nanocomposites were synthesized by an easy one‐step aqueous chemical oxidative polymerization of 4‐aminodiphenylamine (4ADPA) using silver nitrate (AgNO3) as the...Design, synthesis and characterization of novel biodegradable shape memory polymers based on poly(D,L‐lactic acid) diol, hexamethylene diisocyanate and piperazine
A novel series of biodegradable shape memory polyurethane ureas (SMPUUs) were designed and synthesized based on poly(D,L‐lactic acid) diol, hexamethylene diisocyanate and piperazine. Their structure,...Effect of [6,6]‐phenyl‐C61‐butyric acid methyl ester on the morphology of poly(3‐hexylthiophene) film
The change of morphology of poly(3‐hexylthiophene) (P3HT) film as a result of blending with [6,6]‐phenyl‐C61‐butyric acid methyl ester (PCBM) was studied using a freeze‐dry method. A porous structure...Poly(L‐lactic acid) metal organic framework composites: optical, thermal and mechanical properties
Biodegradable composites based on poly(L‐lactic acid) (PLLA) and metal organic frameworks (MOFs) were developed. PLLA without and with the addition of 1, 3 and 5 wt% MOFs was melt compounded in a...The effect of pH and ionic strength on the dispersion of carbon nanotubes in poly(acrylic acid) solutions
The dispersion of three kinds of acid‐treated carbon nanotubes (CNTs) in poly(acrylic acid) (PAA) aqueous solution of different pH and ionic strengths (varied by NaCl, KCl and ZnCl2) was investigated...Effect of liquid isoprene rubber on dynamic mechanical properties of emulsionpolymerized styrene/butadiene rubber vulcanizates

Message from Ms Irina Bokova, Director-General of UNESCO, on the occasion of the World Day for Audiovisual Heritage - 27 October 2011
Message from Ms Irina Bokova,Director-General of UNESCO,on the occasion of the World Day for Audiovisual Heritage 27 October 2011
Among all the types of humanity’s heritage, the audiovisual heritage is one of those that provide the most direct and intuitive access to the wealth of world cultures and the infinite diversity of human civilization.
Audiovisual records offer unique means of learning, sharing and becoming informed through sound and image. They are, in form and content, living testimonies to the history of technology, performance and culture. By presenting images and sounds from foreign cultures, historic moments shaping our collective memory, they contribute to cementing the foundations of intercultural dialogue and enriching humanity’s awareness.
All these records, these films and soundtracks, are also extremely vulnerable. Part of the twentieth century audiovisual archive collection has already disappeared, victim of technological obsolescence, institutional neglect and losses due to deterioration, deliberate destruction or ignorance. The rapid development of the digital world has only compounded the challenges.
Protection of these records is a cultural and educational imperative and must never be taken for granted. Quite the opposite: it is an ongoing task. It is one of the central aspects of UNESCO’s flagship Memory of the World programme, which ensures the protection of humanity’s documentary heritage in all its forms. Many audiovisual records have already been included in the Memory of the World Register: “The Story of the Kelly Gang”, the first feature-length fiction film, the complete original film production of the Lumière brothers, and the “Liberation
Struggle Living Archive Collection”, a unique documentary on the apartheid system in South Africa. They are each an irreplaceable source of learning and discovery. Their loss would impoverish our world heritage and be tantamount to collective amnesia.
To protect the audiovisual heritage, appropriate safeguard measures should be instituted and training and support for archive professionals, libraries and specialized institutions provided. I invite today all UNESCO’s partners and collaborators to redouble efforts to ensure the protection of this unique documentary heritage and help it to fulfil all its educational and cultural promises.
