Electric-Field-Oriented Growth of Long Hair-Like Silica Microfibrils and Derived Functional Monolithic Solids.

Recent Pat Nanotechnol 2017 ;11(3):243-251

Formerly Metals and Ceramics Division, Oak Ridge National Laboratory, Oak Ridge, Tennessee. United States.

Background: Controlled self-assembly using molecules/nanoparticles as building block materials represents an important approach for nanofabrication.

Method: 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.

Instituto de Ciencia de Materiales de Madrid (ICMM), Consejo Superior de Investigaciones Científicas (CSIC), c/Sor Juana Ines de la Cruz 3, Campus de Cantoblanco, E-28049-Madrid, Spain.

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.

Authors:
Giora Rytwo

Recent Pat Nanotechnol 2017 ;11(3):181-193

Environmental Physical Chemistry Laboratory, MIGAL Galilee Research Institute, P.O. Box: 831, Kiryat Shmona 1101602. Israel.

Background: Freshwater resources will not be able to meet all requirements and water should not be considered a self-renewable, low cost resource. Thus, the needs for increased amount of water imply adopting several approaches that include intercepting and transferring water, desalination and water re-use. In all three approaches removal of turbidity and total suspended solids (TSS) is a crucial step, as one of the essential parameters limiting water quality. Read More

Recent Patents on Nano-Enhanced Materials for Use in Thermal Energy Storage (TES).

Recent Pat Nanotechnol 2017 Jul;11(2):101-108

GREA Innovacio Concurrent, Universitat de Lleida, Lleida, Edifici CREA, Pere de Cabrera s/n, Lleida, Spain.

Objective: 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. Read More

Polymer Composite Containing Carbon Nanotubes and their Applications.

Recent Pat Nanotechnol 2017 Jul;11(2):109-115

Department of Applied Chemistry, Dongduk Women's University, Seongbuk-gu, Seoul, Korea.

Background: 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.

A Review on Recent Patents and Applications of Inorganic Material Binding Peptides.

Recent Pat Nanotechnol 2017 ;11(3):168-180

Interdisciplinary Biomedical Research Centre, Nottingham Trent University, Clifton Lane, Nottingham. United Kingdom.

Background: Although the popularity of using combinatorial display techniques for recognising unique peptides having high affinity for inorganic (nano) particles has grown rapidly, there are no systematic reviews showcasing current developments or patents on binding peptides specific to these materials. In this review, we summarize and discuss recent progress in patents on material binding peptides specifically exploring inorganic nano surfaces such as metals, metal oxides, minerals, carbonbased materials, polymer based materials, magnetic materials and semiconductors. We consider both the peptide display strategies used and the exploitation of the identified peptides in the generation of advanced nanomaterials. Read More

Patents on Membranes Based on Non-Fluorinated Polymers for Vanadium Redox Flow Batteries.

Recent Pat Nanotechnol 2017 Jul;11(2):123-129

Department of Chemical Engineering, Kyonggi University, Yeongtong-gu, Suwon, Korea.

Background: 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.

Description: The key constituent of VRFBs is a separator to conduct protons and prevent cross-mixing of the positive and negative electrolytes. Read More
