The use of gold nanoparticles (AuNPs) as labeling carriers in combination with the enzymatic activity of the Horseradish Peroxidase (HRP) in order to achieve an improved optical lateral flow immunoassay (LFIA) performance is here presented.Briefly in a LFIA with an immune-sandwich format AuNPs are functionalized with a detection antibody already modified with HRP, obtaining an "enhanced" label. Two different detection strategies have been tested: the first one following just the red color of the AuNPs and the second one using a substrate for the HRP (3 different substrates are evaluated), which produces a darker color that enhances the intensity of the previous red color of the unmodified AuNPs. In such very simple way it is gained sensitivity (up 3

“…The reaction rates for the production of tritiated methane and tritiated propylene are negligibly small, whereas ethylene reacts significantly with tritium and forms tritiated productions in the catalytic reactor. This selective tritiation of ethylene comes mainly from the fast reaction of hydrogenation of ethylene to ethane at the relatively low temperatures, where an isotopic exchange reaction between ethylene and tritium proceeds slowly [16,17]. Even then, the production of the tritiated ethylene affects negligibly the overall detritiation performance of the DS module since the produced tritiated ethylene can be combusted completely by the catalyst reactor at the temperature for a LTR operated normally around 200°C.…”

Detritiation system of a nuclear fusion plant is mandatory to be designed and qualified taking carefully into consideration all the possible extraordinary situations in addition to that in a normal condition. We focused on the change in the efficiency of tritium oxidation of a catalytic reactor in an event of fire where the air accompanied with hydrocarbons, water vapor, and tritium is fed into a catalytic reactor at the same time. Our test results on the effect of these gases on the efficiency of tritium oxidation of the catalytic reactor indicated; (1) tritiated hydrocarbon produces significantly by reaction between tritium and hydrocarbons in a catalytic reactor; (2) there is little possibility of degradation in the detritiation performance because the tritiated hydrocarbons produced in the catalyst reactor are combusted; (3) there is no possibility of uncontrollable rise in the temperature of the catalytic reactor by heat of reactions; and (4) saturated water vapor could temporarily poison the catalyst and degrades the detritiation performance. Our investigation indicated a saturated water vapor condition without hydrocarbons would be the dominant scenario to determine the amount of catalyst for the design of catalytic reactor of the detritiation system.

“…Earlier, the exchange and redistribution of hydrogen and deuterium have been observed when simple alkenes were deuterogenated over a nickel catalyst giving a mixture of alkanes with varying deuterium content, with the 2 H 4 -derivative as the main product. 13 Another alkene reduction strategy was investigated (Scheme 3). The deuterogenation of linoleic acid 10 (over Pd/C or Pd/ BaSO 4 ), a potential starting material for alkylresorcinols, did not furnish the 2 H 4 -stearic acid 11 cleanly but gave instead a mixture of 2 H 0 up to 2 H 15 isotopologues, 2 H 4 -and 2 H 5 -derivatives being the main products according to MS.…”

“…The preparation of an isotopically labelled long chain 5-nalkylresorcinol has been described only twice. 14 C-heneicosylresorcinol (C 21 ) was synthesized for a metabolism study 7 and 13 Cdodecylresorcinol (C 12 ) was obtained by biosynthesis starting from a 13 C-labelled substrate. 8 Two studies concern the labelling of short alkyl chain (C 5 , C 3 ) analogues which are substructures of tetrahydrocannabinols and their metabolites.…”

Four alternative strategies for the preparation of deuterium poly-labelled 5-n-alkylresorcinols are explored. Ring-labelled 2 H 3 -alkylresorcinols synthesized by acidic H/D exchange are stable under electrospray ionization MS conditions but scrambling occurs in electron bombardment ionization MS. Side chain-labelled 2 H 4 -derivatives prepared by two different total synthesis approaches are contaminated by isotopologues with varying number of deuterium labels due to H/D redistribution and exchange during D 2 gas deuterogenation. The derivative carrying an x-2 H 3 label is isotopically pure and completely stable under all relevant analytical conditions encountered in quantitation work.
