Nitrogen-vacancy (NV) centers in diamond excel as room-temperature quantum sensors by virtue of their long-lived spin coherence and experimental addressability at the single-spin level. When isolated deep within bulk diamond, NVs' spin coherence times and relaxation times are limited to several milliseconds by interna…
The ultrasonic study of oxalic acid and its complex with chromate(III) have been measured in acidic pH solution at different temperature and concentration. The apparent molar volume, adiabatic compressibility, apparent molar compressibility, partial molar volume and partial molar compressibility have been calculated a…
In our work, we focused on reactions of organometallic tin (IV) precursors, such as Sn(OtBu)4, Me3SnCl, and Me3SnF, with β-heteroarylalketonates: 3,3,3-trifluoro(pyridin-2-yl)propen-2-ol, 3,3,3-trifluoro(dimethyl-1,3-oxazol-2-yl)propen-2-ol, and 3,3,3-trifluoro(1,3-benzthiazol-2- yl)propen-2-ol. Obtained compounds were e…
In contrast to the rich marine fossil record that extends to the late Mesozoic, records of pre-Quaternary lacustrine diatom deposits are relatively scarce, particularly from the high latitudes. Such records provide information concerning paleoenvironmental change, as well as new insights concerning the evolution of fr…
The combination of the conventional cathode material, La0.8Sr0.2MnO3-𝛿 (LSM), and exceptional oxygen ion conducting material, (Er0.2Bi0.8)2O3 (ESB), has shown promise as a potential candidate for low temperature solid oxide fuel cell (LT-SOFC) cathodes. Though the initial performance of this composite is encouraging,…
Student performance is one of the most important indicators for assessing the quality of education, the results have a significant impact on increasing motivation for learning and the formation of professional thinking. One way to assess the quality of mastering the discipline «Pharmaceutical Chemistry» is a score-rat…
Na uzorcima korozijski postojanih celika, provedena su laboratorijska ispitivanja te ispitivanja uzoraka u stvarnim uvjetima trosenja. Elektrokemijska ispitivanja provedena su u cilju provjere korozijske otpornosti modificiranih povrsina celika. Na uzorcima korozijski postojanih celika X20Cr13 i X17CrNi16-2, provedena…
The high operating temperatures in solid oxide fuel cells (SOFC) result in high cost, reduced longevity, and decreased efficiency impeding the wide application of this technology. Lowering the temperature of SOFC requires electrolytes with high ionic conductivity at lower temperatures. Stabilized δ-Bi2O3 electrolytes…
Lack of reliable and adequate information on material characteristics of glass fibre reinforced polymer (GFRP) at elevated temperatures lowers the accuracy of analytical and design models developed to predict the behaviour of GFRP reinforced concrete members. There is an essential need to assess the remaining strength…
Two new Schiff base ligands (L1, L2) derived from 2-pyridinecarboxaldehyde, benzaldehyde and 5-amino-1,3,4- thiadiazol-2-thiol have been synthesized. These ligands were treated with Cu (II) and Co (II) chloride with a metal : ligand ratio of 1:1 to afford the four new complexes [CuL1(H2O)2]Cl2, [CoL1Cl2], [CuL2(H2O)2]…
Objective: To prepare BCNU-loaded micelles modified with interleukin-13 (IL13) as gliomas-tar-geting ligand that can penetrate the blood-brain barrier and raise the concentration of BCNU in brain, and en-hance the anti-tumor activity. Methods: BCNU-loaded micelles (BCNU-M) were prepared by film hydration with DSPE-PEG…

It is the process of prevention of corrosion of mild steel from vapors emitted by packing woods. It was observed that the passive film on mild steel surface has been presented. The passive film is stabilized by continued exposure to the passivating environment The vapor of  anthrocene and naphthalene some other relat…
Carbon nanotubes (CNTs) were proposed as a promising interconnection material in future miniaturized electronics, owing to their exceptional electrical and thermal properties. A series of CNT bundles with 1 mm diameter were grown on silicon substrate by thermal Chemical Vapor Deposition (CVD) at temperature 700 oC. Th…
Dizajn novih materijala željenih fizikalnih svojstava danas je jos uvijek vrlo izazovan zadatak. Naime, odgovori funkcionalnih materijala određeni su relativnom orijentacijom gradbenih blokova od kojih je materijal izgrađen. U supramolekulskim arhitekturama organskih krutina do sada je ustanovljeno da se određeni supr…
