UNIVERSIDAD DE ALICANTE posted this:Natural hybrids nanopigments synthesis for multiple industrial applications.The Colour and Vision Research Group of the University of Alicante has been designed a new process to develop nano-structured hybrid nanopigments (from synthetic or natural dyes). These nanopigments confer improved optical, thermal, and mechanical properties when they were applied on composite materials. The nanoclays, dyes, and additives have been selected depending on the composite matrix source. Also, it has been selected the additives order in the process of synthesis, based on the material properties that would be going to improve. The parameters that could be control with this new system are: the adsorbed dye concentration, the degradation temperature of the reinforced dye, the degradation temperature of the final nanocomposite, the bending resistant modulus, and the UV-VIS colour fastness. Also, it can be controlled the optical properties as transparency and colouring power degree. It is looking for companies interested in commercial exploitation of these new colored nanomaterials.
UNIVERSIDAD DE ALICANTE posted this:Novel and simple procedure for dispersing graphene derivatives in chemically curable resins.The Laboratory of Adhesion and Adhesives of the University of Alicante and the company Dental Global Training, have developed a new procedure to incorporate efficiently graphene derivatives (nanofibers, nanosheets, nanoparticles) in chemically cured resins by using an in situ polymerization technique. The method is very simple and fast, it provides an excellent dispersion of the graphene derivatives in both the solid components of the resin and in the cured polymer matrix, and is entirely friendly with the environment. The novel method does not require the use of organic solvents nor water, ultrasounds, and high pressure/temperature. The resulting resin composites show excellent mechanical properties, good wear resistance, easy manipulation and increase the insolubility in oral fluids, and therefor they have special interest in applications in odontology, traumatology and non-medical applications too (automobile, construction, civil engineering, aeronautics, space engineering, electronics and optics). It is looking for companies interested in acquiring this technology for its commercial exploitation.

UATEC - Unidade de Transferência de Tecnologia posted this:Optical pressure sensor based on zirconia nanostructuresA group of researchers from a Portuguese university has developed the concept of a gas pressure gauge based on the control of the luminescence from zirconia nanostructures. The invention aims to measure the gas pressure based on the nanoparticles emission that is different depending on the amount of gas molecules surrounding the nanoparticles. Comparing with existing solutions, the advantage of this process, which operate in a pressure range of interest for various market sectors (ex. Food industry), is the absence of electrical contacts.

UNIVERSIDAD DE ALICANTE posted this:New process for the manufacture of electrodes from superporous nanostructured carbon materialsSpanish University have developed a process for the manufacture of electrodes from superporous nanostructured carbon materials. The process uses electrospraying technique to deposit a suspension of a carbon material over a collector. This method facilitates processing superporous nanostructured carbon materials due to its high efficiency and less complexities compared to conventional techniques. The electrodes obtained can be used in energy storage or analytical sensors in commercial devices.
RAMOT at Tel Aviv University Ltd. posted this:Harnessing inhibitory RNA based- nanoparticles for therapeutic intervention in blood cancersModulating T cells functions by down regulating specific genes using RNA interference (RNAi) holds tremendous potential in advancing targeted therapies in many immune related disorders including cancer, inflammation, autoimmunity and viral infections. Hematopoietic cells, in general, and primary T lymphocytes, in particular, are notoriously hard to transfect with small interfering RNAs (siRNAs). Herein, we describe a novel strategy to specifically deliver siRNAs to murine CD4+ T cells using targeted lipid nanoparticles (tLNPs). To increase the efficacy of siRNA delivery, these tLNPs have been formulated with several lipids designed to improve the stability and efficacy of siRNA delivery. The tLNPs were surface functionalized with anti-CD4 monoclonal antibody (mAb) to permit delivery of the siRNAs specifically to CD4+ T lymphocytes. Ex vivo, tLNPs demonstrated specificity by targeting only primary CD4+ T lymphocytes and no other cell types. Systemic intravenous administration of these particles led to efficient binding and uptake into CD4+ T lymphocytes in several anatomical sites including the spleen, inguinal lymph nodes, blood and the bone marrow. Silencing by tLNPs occur in a subset of circulating and resting CD4+ T lymphocytes. Interestingly, we show that tLNPs internalization and not endosome escape is a fundamental event that takes place as early as one hour after systemic administration that determine tLNPs efficacy. Taken together, these results suggest that tLNPs may open new avenues for the manipulation of T cell functionality and may help to establish RNAi as a therapeutic modality in leukocyte-associated diseases.

RAMOT at Tel Aviv University Ltd. posted this:Heavily doped semiconductor nanocrystalsDoping of semiconductors by impurity atoms enabled their widespread technological application in micro and optoelectronics. However, for strongly confined colloidal semiconductor nanocrystals, doping has proven elusive. This arises both from the synthetic challenge of how to introduce single impurities and from a lack of fundamental understanding of this heavily doped limit under strong quantum confinement. We develop a method to dope semiconductor nanocrystals with metal impurities providing control of the band gap and Fermi energy. A combination of optical measurements, scanning tunneling spectroscopy and theory revealed the emergence of a confined impurity band and band-tailing. Successful control of doping and its understanding provide n- and p-doped semiconductor nanocrystals which greatly enhance the potential application of such materials in solar cells, thin-film transistors, and optoelectronic devices.
