Superoxide dismutase based biosensor for the electrochemical determination of epinephrine
(2018)
New amperometric biosensor for epinephrine was developed, using a screen printed carbon electrode with tetrathiafulvalene (5% v/w) incorporated into carbon ink (SPCTTFE). Electrodic surface was modified with nanoparticles ...
Diseño de una emulsión Pickering fotoactiva
(2023)
Las emulsiones Pickering constituyen un tipo de emulsión estabilizada mediante partículas sólidas en lugar de los convencionales agentes emulsificantes moleculares. Aunque fueron conceptualizadas hace más de un siglo, su ...

(2021)
25B-NBOMe, benzylpiperazine (BZP), 1-(3-chlorophenyl)piperazine (mCPP), and N,N-dimethyltryptamine (DMT) are potent hallucinogenic and stimulant drugs which have emerged as novel psychoactive substances (NPS). The ...
μ2-Chlorido-chlorido(μ2-4-{[2-(diethylamino)ethyl]imino}pent-2-en-2-olato)bis(tetrahydrofuran-κO)cobalt(II)lithium
(2018)
The crystal structure of the title compound, [CoLi(C11H21N2O)Cl2(C4H8O)2], has monoclinic symmetry and comprises one heterometallic binuclear complex molecule in the asymmetric unit. The Co2+ cation is bonded to one oxygen ...
Influence of bitumen and aggregate polarity on interfacial adhesion
(2017)
The quality of the bitumen–aggregate interface formed in an asphalt mixture is dictated by the physicochemical properties of both materials, such as surface polarity. In order to better understand the role of polarity on ...
1-Nitro-4-(1-propyn-1-yl)benzene
(2019)
The title compound, C9H7NO2, was prepared by alkynylation of 4-iodonitrobenzene with 1,3-dilithiopropyne in the presence of 1 equivalent of CuI and catalytic amounts of Pd(PPh3)2Cl2. The complete molecule is generated ...
