The combination of TLC and Bacillus subtilis bioassay was already demonstrated to detect the antibiotics in samples.
One possible candidate to address future nodes (below 16 nm) is electron beam lithography as sub 10 nm resolution was already demonstrated in PMMA or HSQ resists.
Feasibility of swine manure treatment using MFCs was already demonstrated by previous studies, however low Coulombic efficiencies were attained due to a competing methanogenic degradation occurring in the same cells.
The latter was already demonstrated and discussed in [9].
It was already demonstrated that amorphous Mg2Ni exhibits lower hydrogen absorption capacity than crystallized Mg2Ni [18].
Indeed, the application of SiNWs for new type of solar cell was already demonstrated [6].
For these systems, the successful Si-nc formation was already demonstrated.
Regarding the learning speed, it was already demonstrated that η shows lower sensitivity compared to λ.
This was already demonstrated by Egypt's parliamentary election, in which the Salafist Nour party took a quarter of the seats in the new parliament.
The serotoninergic substance is most likely 5-methyl-serotonin, the presence of which was already demonstrated in a CR extract [59].
Especially the latter one, the pentafluorosulfanyl group, was already demonstrated half a century ago (Sheppard 1962) of its impressive stability and compatibility with several reactions.
