eng Modified Seed Growth of Iron Oxide Nanoparticles in Benzyl Alcohol – Optimization for Heating and Broad Stability in Biomedical Applications
Gilliland III, Stanley E.; Carpenter, Everett E.; Shultz, Michael D.
Nanobiomedicine Vol. 1, No. Godište 2014, 2014
Iron oxide nanoparticles have received sustained interest for biomedical applications as synthetic approaches are continually developed for control of nanoparticle properties. However, many approaches focus solely on the material, rather than the complete optimization of synthesis and functionalization together to enhance translation into biological systems. Presented herein is a modified seed growth method designed for obtaining optimal nanoparticle properties and ease of surface functionalization for long term stability. With a one or two add...

hrv Micelarna tekućinska kromatografska analiza benzilnog alkohola i benzaldehida u injekcijskim pripravcima
eng Micellar liquid chromatographic analysis of benzyl alcohol and benzaldehyde in injectable formulations
RIZK, MOHAMED; IBRAHIM, FAWZIA; HEFNAWY, MOHAMED; NASR, JENNY JEEHAN
Acta Pharmaceutica Vol. 57, No. 2, 2007
Razvijena je točna, osjetljiva i selektivna reverzno-fazno micelarna kromatografska metoda za simultano određivanje benzilnog alkohola i benzaldehida. Ta metoda je primijenjena u injekcijskim pripravcima diklofenaka, piroksikama, linkomicina i klindamicina. U koncentracijskom području 10100 i 120 μg mL1 postignuta je izvrsna linearnost s granicom detekcije (S/N = 3) 0,25 μg mL1 (2,3 × 106 mol L1) i 0,12 µg mL1 (1,13 × 106 mol L1) za benzilni alkohol, odnosno benzaldehid. Metoda je uspješno primijenjena za analizu benzilnog alkohola i b...

eng Volatile Organic Compounds of Marine Sponge Petrosia ficiformis from the Adriatic Sea
Radman, Sanja; Maras, Elena; Jerković, Igor
Croatica Chemica Acta Vol. 94, No. 4, 2021
Volatile organic compounds (VOCs) of Petrosia ficiformis were investigated for the first time. The VOCs from fresh and air-dried sponge were obtained by hydrodistillation and headspace-solid phase microextraction and they were analysed by coupled gas chromatography-mass spectrometry. Aliphatic compounds with octan-3-one (up to 24.02 %), oct-1-en-3-ol (up to 8.65 %) and heptadecane (up to 39.37 %) were the most abundant in the fresh sponge along with benzaldehyde (up to 18.59 %) and diisobutyl phthalate (up to 8.44 %). Higher percentage of N,N...

hrv Čišćenje slike Gospa od Karmela Antonija Grapinellija emulzijama na bazi Pemulena tr-2
eng Cleaning the “Our Lady of Carmel” by Antonio Grapinelli with Pemulen TR-2-based emulsions
Kekez, Lana; Lujić, Zrinka
Portal Vol. , No. 3, 2012
Oltarna pala s prikazom Gospe od Karmela djelo je Antonija Grapinellija, venecijanskog slikara sredine 18. stoljeća. Uz opis zatečenog stanja i izvedenih konzervatorsko-restauratorskih zahvata, posebno je izdvojeno čišćenje slike od površinske nečistoće i laka te prijašnjih preslika. Metodologija čišćenja ističe se zbog primjene Pemulena TR-2, materijala primarno osmišljenog za primjenu u kozmetičkoj industriji. Inovativnost primjene navedenog polimernog emulgatora leži u jednostavnoj pripremi vodenih gelova i emulzija. Na konkretnoj problema...
