We made comparison of titanium dioxide powders obtained from three syntheses including sol‐gel and precipitation methods as well using layered (tetramethyl)ammonium titanate a source TiO 2 . The precursors were subjected to step annealing at elevated temperatures transform into rutile form. transformation was determined by Raman measurements in each case. resulting products characterised spectroscopy dynamic light scattering. main goal the studies performed compare temperature titania...
This work is a follow-up study for recently-proposed 3D radiochromic gel dosimeter that contains tetrazolium salt and physical matrix made of poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (Pluronic F-127). Several salts were examined in this work, including violet, blue chloride, nitro chloride (NBT), tetranitro (tNBT) thiazolyl bromide (TBTB). The salt-containing dosimeters compared with the first Pluronic composition contained 2,3,5-triphenyltetrazolium (TTC)...
The poor solubility of clotrimazole in the aqueous medium and uncontrolled removal drug-loaded suppository content limit its effectiveness treatment vulvovaginal candidiasis. We present here formulations form non-Newtonian structured fluids, i.e., Bingham plastic or pseudoplastic fluids constructed hyperbranched polyglycidol, HbPGL, with a hydrophobized core aryl groups such as phenyl biphenyl. amphiphilic constructs were obtained by modification linear units containing monohydroxyl benzoyl...
Nanogels of poly(acrylic acid) have been synthesized using a new method, based on intramolecular cross-linking linear macromolecules in aqueous solution, induced by short (a few microseconds) pulses fast electrons. Simultaneous generation number carbon-centered radicals along the polymer chain results predominantly recombination, with only minor contribution intermolecular cross-link formation and scission. This method allows synthesis nanogels pure system consisting water, absence monomers,...
This work reports the first results obtained using a new 3D radiochromic gel dosimeter. The dosimeter is an aqueous physical matrix made of poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (Pluronic F-127, PEO-PPO-PEO) doped with representative tetrazolium salts, 2, 3, 5-triphenyltetrazolium chloride (TTC). There were several reasons for choice Pluronic as forming substrate: (i) high degree transparency and colourlessness; (ii) possibility preparation at both low...
Abstract This work reports on a new type of combined radiochromic ionizing radiation dosimeter for radiotherapy. The LCV‐Pluronic F‐127 serves this purpose, which is leuco crystal violet embedded in physical hydrogel matrix poly(ethylene oxide)‐ block ‐poly(propylene ‐poly(ethylene oxide) (Pluronic F‐127) with additives. responds to by developing blue color an intensity related the dose. improved lower temperature stability adding sodium chloride (NaCl). Subsequently, method manufacturing...
This work describes the measurements of ionizing radiation dose and determination isocenter using a tool consisting three-dimensional polymer gel dosimeters dedicated software package. Specific were selected. Their inherent common feature is possibility high-resolution measurement distribution in radiotherapy presence N-vinylpyrrolidone monomer composition alongside other substances such as cross-linking agent N,N'-methylenebisacrylamide, oxygen scavengers, stabilizers matrix. The aim this...
Abstract Summary: The new polymer gel dosimeter, based on the modification of VIPAR composition, is described for purpose radiation dose distribution measurement in radiotherapy. It features increased concentration two substrates: N‐ vinylpyrrolidone (8%) and gelatine (7.5%) ( N,N ′‐methylenebisacrylamide was maintained at 4%), addition copper sulphate (0.0008%) ascorbic acid (0.007%) order to facilitate preparation through elimination need deoxygenation gel. Following exposure ionizing...
