Nanoscience and nanotechnology made their appearance in the scientific scene at a time when both the economy of Spain and the Spanish Research and Innovation System were experiencing strong growth. This circumstance resulted in a remarkable development of nanoscience and nanotechnology especially in universities and public research institutions such as the Spanish National Research Council (Consejo Superior de Investigaciones Científicas - CSIC). However, this development in academia has not been reflected in a similar increment in the transfer of knowledge to the productive sector despite several efforts and initiatives were launched...

We present a "bottom-up" fabrication approach to first grow a new class of inorganic (silica) long hair-like microfibrils or microwires and then to form monolithic solid pellet that contains parallel arrays of bundled microfibrils with a controlled orientation. During the sol-gel solution processing, reactive precursor species are utilized as molecular "building blocks" for the field-directed assembly growth of microfibrils driven by an electric field of pulsed direct current (dc) with controlled frequency...

Phytoceuticals have been used extensively worldwide due to their reduced toxicity and therapeutic efficacy. The major drawback associated with their delivery which includes lack of sustained action and lipophilicity has been overcome by applications of scientific approach by scientists and researchers. Novel drug delivery systems aimed at enhancing bioavailability, reducing toxicity and in turn improving the patient compliance have been developed with success in recent times. Recent developments in the modern phytopharmaceutical research methods have also solved the major hurdles related to the extraction, identification of constituents in polyherbal systems, and standardisation thereby further facilitating the formulation of improved dosage forms with better efficacy of the herbal drugs...

Synthesis, properties, structural peculiarities, and applications of nanobuds and related nanostructures are discussed. According to observed properties and those predicted by DFT calculations, the nanobuds are semiconducting and stable in normal conditions, can accept adatoms and molecules. They contain a relatively chemically inert carbon nanotubes and more active fullerene species and can be compatible with a variety of other materials, in particular polymers. In addition to nanobuds for SWCNTs, the nanobuds with graphene, small fullerenes or metal nanobud-like structures are also known...

Thermal energy storage (TES) systems using phase change materials (PCM) have been lately studied and are presented as one of the key solutions for the implementation of renewable energies. These systems take advantage of the latent heat of phase change of PCM during their melting/solidification processes to store or release heat depending on the needs and availability. Low thermal conductivity and latent heat are the main disadvantages of organic PCM, while corrosion, subcooling and thermal stability are the prime problems that inorganic PCM present...

Carbon nanotubes (CNTs) are attractive nanostructures in this regard, primarily due to their high aspect ratio coupled with high thermal and electrical conductivities. Consequently, CNT polymer composites have been extensively investigated for various applications, owing to their light weight and processibility. However, there have been several issues affecting the utilization of CNTs, such as aggregation (bundling) which leads to a non-uniform dispersion and poor interfacial bonding of the CNTs with the polymer, resulting in variation in composite performance, along with the additional issue of high cost of CNTs...

Vanadium redox flow batteries (VRFBs) have received considerable attention as large-scale electrochemical energy storage systems. In particular, VRFBs offer a higher power and energy density than other RFBs and mitigate undesirable performance fading, such as inevitable ion crossover, because of the unique advantage that only the vanadium ion is employed as the active species in the two electrolytes. The key constituent of VRFBs is a separator to conduct protons and prevent cross-mixing of the positive and negative electrolytes...

BACKGROUND: Most of the chemical substances which emerge out as potential drug candidates (Active Pharmaceutical Ingredients) are either weak acids or weak bases. Poor aqueous solubility of these drug substances is a common concern. Several R&D centers are focused on developing suitable, economic, simpler and more feasible solubility enhancement techniques for increasing the solubility and thereby bioavailability of such drug substances. Nanocrystals is one of the preferred approaches for solubility enhancement in last few decades...

A theoretical model has been previously proposed to optimize the structure of the electrical probe memory system, whereby the optimal thickness and resistivity of DLC capping layer and TiN under layer are predicted to be 2 nm, 0.01 Ω× m, and 40 nm, 2×10-7 Ω× m, respectively. However, there is no experimental evidence to show that such a media stack can be fabricated in reality by the time of writing. In order to realize this optimized design experimentally, the thickness dependent resistivity for both DLC and TiN film are assessed, from which it is not possible to obtain a media stack with exactly the same properties as the optimized design...
