A new device is presented for the combinatorial analysis of complex nano-scale material systems. The parallel nano-differential scanning calorimeter (PnDSC) is a micro-machined array of calorimetric cells. This new approach to combinatorial calorimetry greatly expedites the analysis of nano-scale material thermal properties. A power-compensation differential scanning calorimetry measurement is ...

Introduction As a new class of an ultra-high capacity anode material for Li-ion batteries, nano-Si/carbon composites have a considerable potential [1, 2]. In such composites, nano-Si can store lithium faster than bulk Si, and the carbon matrix serves nano-Si with an electrical path to compensate the poor electrical conductivity of Si. Though Si has an extremely high theoretical capacitance up t...

MgO is an important inorganic material, which can be used in many aspects, such as catalyst, toxic-waste remediation agent, adsorbent, and others. In order to make use of MgO, nano-MgO was prepared by ultrasonic method using Mg (CH3COO)2.2H2O as precursor, NaOH aqueous solution as precipitant in this paper. Effect factors on MgO nano-particle size were investigated. Characteristics of samples w...

The cooperative effects between the PANI (polyaniline)/nano-NiO (nano nickel oxide) composite electrode material and redox electrolytes (potassium iodide, KI) for supercapacitor applications was firstly discussed in this article, providing a novel method to prepare nano-NiO by using β-cyelodextrin (β-CD) as the template agent. The experimental results revealed that the composite electrode proce...

Nowadays, nanodevices like small fluidic channels, semiconductor lasers, nano contacts for solar cells, nano magnets or nano antennas for infrared detection (THz) are of great interest. The applications for these devices extend the fields of e.g. energy, computational or medical sciences. For example, by arranging nano dots consisting of a magnetic material, logical circuits can be designed whi...

Chemically functionalized and nanostructured materials, which mimic the features of the natural extracellular matrix, provide a tool to organize cell surface receptors into nanoscale clusters and manipulate cell functions. However, the existing materials are mainly based on static structures. Herein, we developed a DNA based structure-switchable and multivalent material that acts as a 'nano-spr...

The aim of this study is to evaluate the use of our nano-HA/PCL composite 3D scaffolds as graft materials for mastoid cavity obliteration in an animal model. Nano-HA particles were synthesized by chemical precipitation technique and mixed them with PCL solution to make composite paste. 3D scaffolds were fabricated by a paste extruding deposition process. The nano-HA/PCL 3D scaffolds showed good...
