We present the electrochemical detection of mephedrone in forensic samples using independent redox processes synthetic cathinones on a graphene screen-printed electrode.
The use of synthetic cathinones (SCs) has increased in recent years, posing significant public health problems due to their adverse effects and potential for fatal poisonings. structural diversity rapid emergence new SC analogues create challenges law enforcement drug screening techniques. This work presents the first time electrochemical detection SCs using differential pulse voltammetry (DPV) on a boron-doped diamond electrode (BDDE). We analyzed 15 SCs, including well-known compounds such...
3,4-methylenedioxypyrovalerone (MDPV) is a harmful and controlled synthetic cathinone used as psychostimulant drug sport-enhancing substance. A sensor was developed for the direct analysis of MDPV by transducing its oxidation signal means an electropolymerized molecularly imprinted polymer (e-MIP) built in-situ on screen-printed carbon electrode’s (SPCE) surface previously covered with multi-walled nanotubes (MWCNTs) silver nanoparticles (AgNPs). Benzene-1,2-diamine functional monomer while...
A SiO₂-SO₃H amorphous catalyst containing a small surface area of 115.0 m²g-1 and 1.32 mmol H+/g was prepared from fine construction sand sodium carbonate sulfonated with H₂SO₄. In 10% (w/w) basis, it is very efficient for catalyzing the esterification carboxylic acids phenol. The reaction processes were performed using conventional heating under microwave irradiation. yields higher in microwave-irradiated esterification. could be used three sequences both processes.
Nesse trabalho o modelo multiobjetivo relativo à colheita de cana-de-açúcar, coleta e geração energia provenientes do aproveitamento sua biomassa é proposto a partir outros já divulgados na literatura. Análise soluções desse realizada explorando-se um procedimento híbrido envolvendo os métodos previsor-corretor primal-dual pontos interiores, branch-and-bound da soma ponderada. Este visa determinar escolha das variedades cana-de-açúcar que minimizam custo cana e/ou maximizam balanço...
The ionic liquid 3-methylimidazolium hydrogensulfate is soluble within the glycerol phase that it creates, after catalyzing transesterification of sunflower oil to fatty acids methyl esters with methanol. Separation this and addition acetone allow production 5-membered ketal 2,2-dimethyl-1,3-dioxylane-4-yl-methanol, in which catalyst insoluble removed by decantation. After drying under vacuum, ready rerun two-stage cycle no apparent loss activity.

3',4'-Methylenedioxy-N-tert-butylcathinone (MDPT), also known as tBuONE or D-Tertylone, is a synthetic cathinone (SC) frequently abused for recreational purposes due to its potent stimulant effects and similarity illegal substances like methamphetamine ecstasy. The structural diversity rapid introduction of new SC analogs the market poses significant challenges law enforcement analytical methods preliminary screening illicit drugs. In this work, we present, first time, electrochemical...
