This work is focused on the application of Cu-containing zeolites as potential environmental sensors for monitoring carbon monoxide. A number commercial with different structural properties (NaX, NaY, MOR, FER, BEA and ZSM-5) were modified using CuSO4, Cu(NO3)2 Cu(OAc)2 solutions copper sources to prepare Cu+-containing zeolites, since Cu+ forms stable complexes CO at room temperature that can ...

OBJECTIVES Prevalence of opioid addiction has alarmingly increased over the recent years. In South Asian region alone there are more than 10 million opioid abusers amounting to 2% of world population. Detoxification remains to be the first step for the successful treatment of opioid addiction. The present study was carried out to compare the relative efficacy and safety of buprenorphine -naloxo...

Infrared spectroscopy has been used in adsorption studies of trimethyl phosphite (TMP) on the hydrogen (H) form of the A-type and 13X zeolites. Infrared spectra of H-zeolites, except H-KA, show that TMP reacts rapidly with silanol hydroxyls on their surfaces and gives rise to form product molecules such as SiOCH3 and liquid dimethyl phosphite. The unaccomplished adsorption on the HKA zeolite ha...

The mass spectrometric behavior of palladium(II) halide complexes of three types of quinolinylaminophosphonates, diethyl and dibutyl esters of [α-anilino-(quinolin-2-yl)methyl]phosphonic (L1, L2), [α-anilino-(quinolin-3-yl)methyl]phosphonic (L3, L4), and [α-(quinolin-3-ylamino)-N-benzyl]phosphonic acid (L5, L6), was investigated under positive ion electrospray ionization conditions. Each type o...

The development of stretchable organic thermoelectric materials is prompted by fast evolving application fields like flexible electronic devices, soft robotics, health monitoring and internet-of-things. Stretchability in usually obtained using an insulating elastomer, either as a substrate or matrix blend composite, which, unfortunately, leads to compromise performance. Herein, potential soluti...
