In this study, dual-triangularly patterned micro/nanorod hierarchical structures were fabricated using a simple combination of the microsphere lithography–reactive ion etching (RIE) process and the nanosphere lithography–RIE process in order to fabricate superhydrophobic surfaces. For the comparison of the wetting pro…
We discuss some aspects of how graphene could be used in mainstream electronic devices. The main focus is on signal processing applications in high-volume, industrially manufactured battery-powered devices, e.g. mobile phones and laptop computers, but we will also discuss applicability to other components like interco…
Tunable microwave magnetoelectric devices based on layered ferrite-ferroelectric structures are described. The theory and experiment for attenuator, band-pass filter and phase shifter are presented. Tunability of the ME devices characteristics can be executed by application of an electric field. This electric tuning i…
Superhydrophobic self-cleaning surfaces were produced with simultaneous wide-angle optical transmittance in the near-infrared region and antireflection properties from combination of multi-scale surface topology based on silica nanoparticles, index grading and interference.
Dendritic gadolinium chelates as magnetic resonance imaging (MRI) contrast agents (CAs) have shown great potential in blood pool and tumor imaging due to their enhanced relaxivities (R1s), prolonged blood circulation time, and homogeneous pharmaceutical properties. However, the non-biodegradability of the currently us…
In this paper, a computer controlled microreactor to synthesize water soluble CdS and CdS/ZnS nanocrystals with in situ monitoring of the reaction progress is developed. It is based on ceramic tapes and the Low-Temperature Co-fired Ceramics technology (LTCC). As well the microsystem set-up, the microreactor fluidic de…
High temperature solid oxide cells, operated alternately in electrolyser or fuel cell mode, represent an appealing approach for efficient electricity storage via hydrogen production/consumption. This paper analyses the thermal balance of a solid oxide electrolyser cell/fuel cell to enable highly transient operation at…
Water-soluble poly(poly(ethyleneglycol)monomethacrylate)-grafted (P(PEGMA)-grafted) Fe3O4 nanoparticles synthesized via a solvent-free atom transfer radical polymerization (ATRP) method were conveniently surface-modified with 3-aminopropyltrimethoxysilane as anchor molecules to donate NH2 groups. Fluorescent magnetic…
A verification study of ultrasound transmission numerical simulation results with experiment results is presented in this paper. The work considers a model of a transformer tank which is filled with electro insulating oil. In the experiment, performed under laboratory conditions, an ultrasound wave is generated by a p…
Based on life cycle assessment(LCA),a quantitative analysis of energy consumption and greenhouse gas emission caused by primary aluminum and recycled aluminum in China in 2008 was carried out.The main reason for the gap between China and international average level was found out through the comparison.The results show…
This chapter discusses the potential of cellulosic nanoparticles or nanocellulose (microfibrillated cellulose and cellulose nanocrystals) extracted from lignocellulosic fibers for the reinforcement of composite materials. The chapter first describes the hierarchical structure of natural fibers and the expected effects…
In order to elucidate the mechanism behind the decrease in the brittle-to-ductile transition (BDT) temperature with the addition of Ni, impact tests and tensile tests were performed at various test temperatures from 130K to 320K with Ni added ultra-low carbon steels. The dependence of absorbed impact energy on tempera…
A conducting polymer electrolyte based on carboxy methylcellulose (CMC) complexed with different concentrations of salicylic acid (SA) has been investigated. The ionic conductivity of the solid polymer electrolyte (SPE) of pure CMC obtained at room temperature is 8.49 × 10 − 10 S cm − 1 . The maximum ionic conductivit…
Size-controlled Stöber silica particles were prepared using a sol–gel methodology. The Stöber silica particles were subsequently reduced using magnesium powder at 500 °C to yield silicon nanocrystals (Si-NCs) that were further reacted with trioctylphosphine oxide (TOPO) to yield hydroxyl terminated, TOPO encapsulated…
Azuliporphyrins were reacted with [Ir(COD)Cl](2) in refluxing o- or p-xylene to give novel iridium(III) derivatives that regioselectively incorporated an oxidized solvent molecule. The iridium(III) is inserted within the porphyrinoid macrocycle and possesses an additional apical acyl unit.
Di-cationic Zn(II)-phthalocyanines (ZnPcs) are promising photosensitizers for the photodynamic therapy (PDT) of cancers and for photoinactivation of viruses and bacteria. Pegylation of photosensitizers in general enhances their water-solubility and tumor cell accumulation. A series of pegylated di-cationic ZnPcs were…
Using electrodeposition and flip-chip bonding, a cross-plane thin film device consisting of 242 pairs of the electrodeposited n-type Bi–Te and p-type Sb–Te thin film legs was successfully fabricated. The electrodeposited Bi–Te films with the thickness of 2.5–20.2 µm exhibited the Seebeck coefficients of −52 to −59 µV/…
By choosing the proper SERS substrate and using a low concentration of p-aminothiophenol (PATP) solution, we observed the genuine SERS spectra of PATP, in which the vibrational modes of 4,4′-dimercaptoazobenzene (DMAB) at 1140, 1390, 1432 cm−1 are not observed, and the SERS spectra is the same as the Raman spectra of…
We present a method to asymmetrically functionalize dimer particles with gold nanoparticles. Our method enables the fabrication of asymmetrically functionalized dimer particles on a large scale.
The formation mechanism of the thermodynamically unstable calcite phase, very high Mg calcite, in biological organisms such as sea urchin or corallina algae has been an enigma for a very long time. In contrast to conventional methods such as KBr pellet Fourier Transform infrared (FTIR) spectroscopy and X-ray diffracti…
