@MaraLui56385486 @LatinXChem and we conducted 5 cycles of the dephosphorylation reaction, and our catalyst showed no signs of leaching, demonstrating its ability to be reused even after multiple cycles. (2/2)

@MaraLui56385486 @LatinXChem Hi María, thank you for your question! Our multifunctionalized graphene is capable of performing both the dephosphorylation reaction and the reduction of a nitro group, which sets it apart from other nanomaterials that typically cannot achieve both. (1/2)

@IanVioli @LatinXChem @nanoscale_rsc @green_rsc @beyondbenign @RSC_Sus (3/3) The issue of leaching is a crucial aspect of this research proposal because it doesn't solely depend on the formation of covalent bonds. The interaction between CNT and CuO can also be highly stable. But ongoing recycling tests will provide clarity on this matter.

@_MartinezAndre_ @LatinXChem @nanoscale_rsc @green_rsc @beyondbenign @RSC_Sus Hi André! Very nice work. Have you tried control experiments employing only the CNT / only de CuxO NPs in the degradation of DNP? What about the leaching of NPs/CNT, is it really an heterogeneous catalyst? Thanks in advance!

@IanVioli @LatinXChem @nanoscale_rsc @green_rsc @beyondbenign @RSC_Sus (2/3) However, when considering isolated CuOxNPs, this material lacks stability without any supporting material. With this instability leading to aggregation and, subsequently, a lack of catalytic performance.

@IanVioli @LatinXChem @nanoscale_rsc @green_rsc @beyondbenign @RSC_Sus (1/3) Hi Ianina, I appreciate your questions! Tests using only CNTs are underway and data obtained will be of most value. However, it's important to note that significant catalytic activity is not anticipated from CNT by itself; literature shows it requires the presence of NPs.

@EliasPFNeto @LatinXChem @nanoscale_rsc @green_rsc @beyondbenign @RSC_Sus (2/2) Consequently, in case that dinitrophenol is not completely oxidized, it could potentially yield even more toxic compounds. With this in mind, to determine the specific product produced during the detoxification process the reduction route is a more favorable choice.

@_MartinezAndre_ @LatinXChem @nanoscale_rsc @green_rsc @beyondbenign @RSC_Sus Hi André! Interesting work! I was wondering with your catalyst could be used as a heterogeneous photocatalyst for the same reaction without addition of NaBH4. What do you think? Have you tried any photocatalytic test?

@EliasPFNeto @LatinXChem @nanoscale_rsc @green_rsc @beyondbenign @RSC_Sus (1/2)Hello Elias! I'm delighted by your interest. While we haven't conducted a photocatalytic test as of now, upon reviewing other photocatalytic tests (doi.org/10.1016/j.jpho…), it is evident that these degradation processes tend to exhibit non-selectivity.

Greetings, @LatinXChem! I'm Maria, PhD at @GqmUfpr. Today at #LatinXChemNanoMat, I'll showcase my research on liquid-liquid interface techniques for ternary thin film synthesis. Take a look and don't hesitate to ask any questions! #NanoMat108 #LatinXChem23.

Hello @LatinXChem, today I will present my latest results titled "Utilization of Dendrimer-Stabilized Silver Nanoparticles in the Construction of SPR Biosensors" #Ana49 #LatinXChemAna #LatinXChem23 @MethodsRSC @AnalysisSensing @GqmUfpr @AldoZarbin

@WTakarada 💅

Phenol-derivatives are known to be #pollutants and some are byproducts of #pesticides neutralization... How can we treat them?

Hi @LatinXChem! This year I'm presenting the work developed in my PhD at @GqmUfpr and as a visiting researcher at @OfficialUoM! When liquid-liquid thin films meet liquid-liquid electrochemistry! It's a match! 🇧🇷🇬🇧 #LatinXChem23 #LatinXChemNanoMat #NanoMat115 @nanoscale_rsc
