We demonstrate for the first time highly reliable actuators based on two-way shape memory effect (TWSME). Under life test, our actuators endure 300.000 loading cycles without performance degradation (fade out or amnesia). Further, we developed manufacturing technology which enables programming of the actuator deformat…
The europium-doped barium strontium titanate (BST:Eu) films find application in ferroelectric as well as in optoelectronic devices. In this paper, we report the pulsed laser deposition (PLD) of BST:Eu thin films. The structural and optical properties of the PLD-grown BST film have been investigated and correlated. The…
The crystallography, phase relationships, and magnetic properties of the Ce5Si4−xGex alloys with 0≤x≤4 have been investigated by using x-ray powder diffraction and isothermal magnetization measurements. There are three different crystal structures in the Ce5Si4−xGex system: the Zr5Si4-type tetragonal structure with sp…
The performance of the composites is determined on the basis of the interface bonding of the filler and the polymer matrix. Particulate filled polymer composites are used extensively for their wide range of applications at low cost. In this study, the effect of the mica with different particle size and different fille…
Uniform Gd 2 O 3 : Eu 3+ luminescent nanowires were prepared on a large scale by a facile solvothermal method using polyethylene glycol (PEG‐2000) as template and ethanol as solvent; the properties and the structure were characterized. X‐ray diffraction (XRD) patterns and Fourier transform infrared spectrometry (FTIR)…
Uniform and well-crystallized octahedral microcrystals have been successfully synthesized by a facile one-step hydrothermal synthesis method without involving any templates. The prepared samples were systematically characterized by powder X-ray diffraction, field-emission-scanning electron microscopy, photoluminescenc…
Nephrogenic systemic fibrosis is a recently recognized disease entity that is potentially debilitating. The exact pathogenesis of nephrogenic systemic fibrosis is unclear, but the disease has been linked with the use of gadolinium-based contrast agents, predominantly in patients with acute renal failure or end-stage r…
We study heat transport in a chain of harmonic oscillators with random \nelastic collisions between nearest-neighbours. The equations of motion of \nthe covariance matrix are numerically solved for free and fixed boundary \nconditions. In the thermodynamic limit, the shape of the temperature profile \n…
Energy is an important cost factor in the U.S iron and steel industry. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. iron…
In this review we briefly discuss the magnetocaloric properties of the manganites. It is evidenced that the maximum entropy change observed in manganites exceeds that of gadolinium (the prototype material for room temperature refrigerators). For the manganites characterized by second-order magnetic phase transitions t…
Cellulose is an almost inexhaustible source of raw material for the increasing demand for biodegradable products, and its solvent is a key for the research and developments. This chapter summarizes the aqueous cellulose solvents, such as NaOH aqueous, NaOH/urea aqueous, NaOH/thiourea aqueous and LiON/urea aqueous syst…
Pediatric and geriatric patients, have difficulty swallowing or chewing solid dosage forms. Many pediatric and geriatric patients are unwilling to take solid preparations due to fear of choking. Even with fast dissolving tablets there is a fear of choking due to its tablet type appearance. Hence oral film drug deliver…
The impact of mineral fillers to the moisture resistance of the wood-plastic composites (WPC) is studied. Five inorganic fillers were tested for the wood-plastic composites calcium carbonate, two d ...
Rare-earth (RE) ions are widely investigated luminescent centers because their intraionic-4f transitions generate narrow and intense emission lines. In this work Eu doped ZnO nanoneedles have been grown, by a thermal evaporation-deposition method, and structural and luminescence characterization has been carried out.…
In this study, magnetite nanoparticles (MNPs) with series of size varying from 8 nm to 103 nm were synthesized by a chemical co-precipitation and an oxidationprecipitation method to aim for finding the optimum particle size which has high heating efficiency in the applied magnetic field (9.6–23.9 kA·m–1, 100 kHz). The…
The potential feasibility of anionic clay hydrotalcite for removal of eriochrome black dye from aqueous solution was investigated. The effects of various experimental parameters such as contact time, pH and adsorbent dosage were investigated. The extent of eriochrome black dye removal increased with the increased in c…
Over the years, biological imaging has seen many advances, allowing scientists to unfold many of the mysteries surrounding biological processes. The ideal imaging resolution would be in nanometres, as most biological processes occur at this scale. Nanotechnology has made this possible with functionalised nanoparticles…
2 Abstract: Polyester (P), cotton (C) and Polyester-Cotton (PC) blended fabrics were treated with 350gpl of phosphorous containing flame retardant (FR) chemical. Oxidative thermal degradation of these fabrics before and after the treatment was studied using Thermogravimerty (TG) - Differential Thermal Analysis (DTA).…
1-Ethyl-3-methylimidazolium bis(oxalato)borate ([Emim][BOB]), a room-temperature ionic liquid, has been prepared and used for the first time to develop new borate-containing material. A new open-framework cobalt borophosphate, (NH(4))(7)Co(4)(H(2)O)[B(2)P(4)O(15)(OH)(2)](2)[H(2)PO(4)][HPO(4)], with peanut shaped extra…
Europium-doped zinc aluminate (ZnAl2O4:Eu3+) films were prepared by the dip-coating technique using a non-alkoxide precursor sol-gel method in ethanolic medium. Photoluminescence spectra displayed the main excitation bands at 270 and 393 nm. The emission spectra of the film heated at 500 ºC displayed bands at 578, 590…
