A total of 137 urine samples and 46 serum samples, corresponding to 154 self-confessed designer drugs consumers in Ibiza island, were analyzed for the presence of designer drugs: amphetamine and amphetamine derivatives (methamphetamine, methylenedioxymethamphetamine (MDMA), methylenedioxyethylamphetamine (MDEA), methylenedioxyamphetamine (MDA), p-methoxymethylamphetamine (PMMA), p-methoxyamphet...

Using Microgenics unique technology, cloned enzyme donor immunoassay (CEDIA), the multiplex assay (CEDIA Amphetamines/Ecstasy) has been developed for the detection of amphetamine, methamphetamine, and ecstasy drugs at cutoff level either of 500 ng/mL or 1000 ng/mL applicable for either qualitative screening or semiquantitative measurement. The multiplex assay detects the total concentration of ...

Cationic waterborne polyurethane as a new dispersing polymer was synthesized by using relatively hydrophilic polyols. Dispersing cationic polyurethane (DCPU) nanocomposites were prepared using isophorone diisocyanate (IPDI), polyethylene glycol (PEG) with different molecular weights (Mn=200, 400, 600,and1000 g/mol), N-methyl diethanolamine (MDEA), dibutyltin dilaurate (DBTDL) and different perc...

Methyldiethanolamine (MDEA) atau yang sering disebut amine memiliki rumus CH3N(C2H4OH)2 adalah suatu cairan kimia ketika dicampurkan dengan 50 % air mempunyai kemampuan untuk menyerap CO2 dari stream gas dan dapat dilepas kembali memanaskan sampai di atas suhu penguapan air. Amine banyak mengandung rich amine. Richamine dipanaskan tujuan menghilangkan kemudian lean Pengujian pada content ini ya...

In the last years, reduction of CO2 emissions from steel industry has been great importance. Carbon capture, oxygen blast furnaces and top gas recycling technologies, among others, have deeply studied as low carbon solutions. this paper, a novel integration capture power to technologies in steelmaking is presented. Green hydrogen via proton exchange membrane (PEM) electrolysis methyldiethanolam...

Carbon capture technologies have been recognized as a potential alternative to alleviate global warming. and storage (CCS) is preferred over carbon conversion utilization (CCU) due its lower operating costs higher CO2 reduction capability. Nevertheless, has the be more economical if value-added products are produced. This highlights importance of assessing routes alternatives in management. rev...
