BACKGROUND: The association of gadolinium-based contrast agents (GBCAs) with nephrogenic systemic fibrosis (NSF) has led to a heightened awareness towards patients' renal function. Whereas detailed guidelines exist for the use of GBCAs in adult patients, best practice is less well defined in children, especially in th…
The effects of thin Al2O3 layers interposed between atomic layer deposited SrTiO3 (STO) films and Ru substrates on the growth and properties of STO films were examined. Although a 3–4 nm thick TiO2 barrier layer was necessary to completely suppress the oxygen diffusion from the underlying Ru(O) layer, which could resu…
Kinetics of passive film growth on a CoCrMo biomedical alloy have been studied using the Electrochemical Quartz Crystal Microbalance technique (EQCM) in phosphate buffer solution at room temperature and 37°C. CoCrMo layers were deposited on the quartz crystals by physical vapor deposition (PVD) reaching a dense and co…
An anode supported solid oxide fuel cell (SOFC) with a dual layer anode consisting of a Cu-CeO 2 impregnated Ni-yttria stabilized zirconia (YSZ) support outer layer and a Ni-YSZ electroactive inner layer was investigated for the direct operation on ethanol. High electrochemical performance without evidence of anode co…
The chromium salt tanning system, which is still the most popular leather tanning procedure, is under continuous pressure from environmental groups and international regulations. Therefore, for many years, numerous experiments have been carried out on chromium-free leather production. In this study, newly produced syn…
The entrapment of anticancer drug ellipticine in the dipalmitoylphosphocholine (DPPC) liposome and its release by addition of three different bile salts, namely sodium deoxycholate, cholate and taurocholate, have been studied by steady state and time resolved fluorescence spectroscopy. We found that the release of the…
We apply the versatile method of in situ hydrophobization of aluminum oxide particles with short amphiphiles for the stabilization of water-in-toluene emulsions. We found that octyl gallate is an ideal surface modifier to adjust particle wetting properties in toluene. The most important parameters affecting the drople…
The electrochemical deposition of ZnO thin films (2D layers) and nanowires on glass substrates covered with transparent conductive oxide (TCO) was studied with the purpose to use them in nanostructured solar cells. It was shown that the bath temperature and the electrolyte concentration played an important role on the…
Vacuum ultraviolet (VUV) spectroscopic properties of undoped and Tb3+-doped Ba3Sc(BO3)3 were investigated by using synchrotron radiation. The Tb3+-doped Ba3Sc(BO3)3 sample crystallized in a flower-like shape even was synthesized at 1100 °C. Upon VUV excitation, Ba3Sc(BO3)3 exhibited an intrinsic broad UV emission cent…
Formation and Characterization of Oriented Micro- and Nanofibers Containing Poly (ethylene oxide) and Pectin, Furlan, R., Rosado, J. A. M., Rodriguez, G. G., Fachini, E. R., da Silva, A. N. R., da Silva, M. L. P.
The Yttrium ions substituted Ni-Zn ferrites powders were prepared using a sol-gel technique. The crystal structure, magnetic properties and microwave absorption properties of the Ni-Zn ferrites powders were studied by X-ray diffraction, vibrating sample magnetometer and vector network analyzer. The results show that t…
Solid lipid nanoparticles (SLN) stabilized by nonionic polysorbate or block copolymer surfactants were used for the preparation of hierarchical meso–macroporous silica through a co-templated approach combining a cooperative templating mechanism (CTM) with micelles and spherical soft matter particles imprinting. Depend…
One-pot salt metathesis reaction of anhydrous LnCl3 with one equivalent of guanidinate lithium [(SiMe3)2NC(NCy)2]Li (Cy = cyclohexyl), following the introduction of two equivalents of NaN(SiMe3)2 or LiN(SiHMe2)2 in THF at room temperature, afforded a family of mono(guanidinate) rare earth metal bis(amide) complexes [(…
Highly ordered semiconducting metal oxide nanorod arrays on transparent and flexible substrates are promising materials for modern optoelectronic and electronic devices, such as touch screens, flexible displays, and printable electronics components. Herein, a modified nanocrystal-seed-directed-hydrothermal route has b…
Regenerable hydrogen storage of lithium amidoborane is firstly achieved through the routes of direct thermal dehydrogenation and subsequent chemical hydrogenation of its dehydrogenated products by treatment with hydrazine in liquid ammonia.
Fine-tuning the design of polymer-doxorubicin conjugates permits optimization of an efficient nanocarrier to greatly increase intracellular uptake and cytotoxicity. Here, we report synthesis of a family of self-assembled polymer-doxorubicin nanoparticles and an evaluation of the effects of various types of side-chains…
Efficient delivery of anti-cancer drugs into tumor cells for enhancing the intracellular drug concentration is a major challenge for cancer therapy due to the instability of drug-loading vehicle. In this report, we developed a simple method to stabilize the nanostructure of micelles only by bubbling air to crosslink t…
Mesoporous nanoparticles functionalized with amino groups on the pore surface and quaternary ammonium groups on the particle surface with particle sizes of 500–800 nm in length and 300–500 nm in diameter and a pore size of 7.2–7.4 nm, have been obtained through a post-synthesis and co-condensation method. Bleomycin (B…
