Novel synthesis of gold nanoparticles supported on functionalized silica
Recently, we presented stable silica-supported gold nanoparticles (AuNPs) suitable for catalysis, obtained by using as the only reactants a gold precursor, chloroauric acid (HAuCl4), and commercial polyethyleneimine-functionalized silica beads (SiO2-PEI), with the need for neither external reducing agents nor conventi…
Strong Coupling and Coherent Phenomena in Semiconductor Metamaterials
Metamaterials are nanoengineered materials with electromagnetic properties beyond those found in nature. Recently, interest has focused towards controlling light matter interaction using metamaterials for applications in nanoscale emitters from lasers to single photon sources. We propose an active metamaterial with em…
Swellipsometry in Twente : Measuring Polymer Swelling by In-Situ Ellipsometry
Thin and ultra-thin (<100 nm) polymer films are frequently used in important technological areas, including coatings, barrier and membrane applications. In these areas the films are frequently exposed to interacting penetrants. The interactions may significantly change equilibrium and dynamic properties of the thin fi…
Similarities between Cell Method and Non-Standard Calculus
Infinitesimal analysis has without doubt played a major role in the mathematical treatment of physics in the past, and will continue to do so in the future, but we must also be aware that several important aspects of the phenomenon being described, such as its geometrical and topological features, remain hidden, in us…
The synthesis of vertically aligned carbon nanotubes on nanostructured porous silicon template by in-situ catalyst double thermal chemical vapour deposition method / Noor Asnida Asli
Nanastructured porous silicon template (NPSiT) was successfully prepared from [100] orientation p-doped silicon (Si) substrate by photo-electrochemically anodization method with optimization parameters of etching time and annealing temperature while the rest of parameters were fixed. Uniform porous structures, optimum…
Silicon and Carbon-Based Anode Materials for Lithium and Sodium-Ion Rechargeable Batteries
This thesis is focused on the Si-based anode materials for lithium-ion batteries (LIBs) as well as biomass-derived carbons for LIBs and sodium-ion batteries (NIBs). In our first attempt we investigated the effect of the support growth substrate as well as of aluminum coating layers on the electrochemical performance o…
Study on thermal conduction for low-dimension magnetic materials
The thermal conduction research process of low-dimensional magnetic material is a complicated process. In this process, the higher requirement on growing condition of monocrystal is proposed. For growing process of, the thermal conduction conditions produce the important influence on monocrystal forming; in the proces…
Si-DLC coatings optimized for low wear and low friction applications
Diamond-like carbon (DLC) has excellent properties for the use as tribological coating such as high hardness, high wear resistance and a low friction coefficient. Nanolayer systems of hydrogenated diamond-like carbon (a-C:H) and silicon doped hydrogenated diamond-like carbon (Si-DLC or a-C:H:Si) have been studied. The…
Magnetoresistance Effects in Carbon-Based Nanostructures
Magnetoresistance (MR) effect is extensively used in state-of-the-art magnetic field sensing and data storage devices. In this work, we present (a) current-perpendicular-to-plane (CPP) MR effect in multilayer graphene (MLG) grown on cobalt (Co) foil and (b) spin valve MR effect in a vertical array of multiwall carbon…
Tuning Electronic Properties of Low Dimensional Materials
Discovery of grapheme has paved way for experimental realization of many physical phenomena such as massless Dirac fermions, quantum hall effect and zero-field conductivity. Search for other two dimensional (2D) materials led to the discovery of boron nitride, transition metal dichalcogenides(TMDs),transition metal ox…
Covalent-bonded graphyne polymers with high hardness
Eight covalent-bonded graphyne polymers have been proposed using the newly developed USPEX and CALYPSO methods based on the first principle calculations. These polymers are energetically more favorable than the corresponding graphyne under ambient pressure, and seven of them are more stable than fullerene C₆₀, indicat…
Large Area Micro-Channel Plates for LAPPDTM
Manufacturing plans for “next generation” microchannel plates (MCPs) and the technical advantages enabled by this evolving technology are presented. The Large Area Picosecond Photodetector (LAPPD) is an MCP based photodetector, capable of imaging, with high spatial and temporal resolution in a hermetic package with an…
The Hydrothermal Synthesis of 1D Biomedical Hydroxyapatite Nanostructures
1D hydroxyapatite nanostructures such as nanotubes, ultra long nanowires and other morphological varieties have been promising material for bone reconstruction and therapy. Advantages like high specific surface, packing properties and mechanical properties make those nanostructures excellent candidates for scaffolds.…
CINÉTICA DE POLIMERIZACIÓN DE SISTEMAS BICOMPONENTES
Los polimeros termoestables se preparan a partir de resinas de bajo peso molecular que son polimerizadas por condensacion o adicion empleando agentes reticulantes. El polimero que se obtiene esta muy entrecruzado formando una red tridimensional, lo que los convierte en polimeros insolubles e infusibles. Debido a esto…
建筑师们住哪？WHERE ARCHITECTS LIVE
建筑师自己家中的风格会是其独特设计风格的延续吗？还是展现出完全不同的另一种风格？策展人弗朗西斯卡·蒙坦尼（FRANCESCAMOLTENI）和戴维德·皮兹公尼（DAVIDEPIZZIGONI）一起合作的“建筑师们住在哪”展便是对这些问题和人们的好奇心的回应。但并不只限于满足我们的好奇心。著名英国建筑师理查德·罗杰斯（RICHARDROGERS）曾说过：“一间房是一个城市的起点（AROOMISTHEBEGINNINGOFACITY）”，这句似乎也正是此展览的目的，尝试理清建筑师的个人品味和喜好，如何影响到他们的建筑作品。
グルコースイソメラーゼの結晶化に及ぼす微小重力効果: Nanostep 2プロジェクト提案に向けた共同研究
We focus on the growth mechanism of protein crystals and their perfection. The growth mechanism will be studied by surface observation and by measuring growth rates. Crystal defects will be studied by special etching and X-ray topography. We successfully carried out Nanostep experiments in 2012 using lysozyme crystals…
Development of a novel hydrogel for skin regeneration
Skin lesions are traumatic events that lead to increased fluid loss, infections, scars formation and the appearance of immunocompromised regions. The loss of skin integrity can result in significant physiological imbalances and disability or even death. Skin functionality must be restored quickly in order to maintain…
