Delayed Capillary Flow of Elastomers: An Efficient Method for Fabrication and Nanofunctionalization of Flexible, Foldable, Twistable, and Stretchable Electrodes from Pyrolyzed Paper
Pyrolyzed cellulose-based materials are extensively used in many fields for many different applications due to their excellent electrical properties. However, pyrolyzed materials are extremely fragile and prone to crack (…)
Ordinary microfluidic electrodes combined with bulk nanoprobe produce multidimensional electric double-layer capacitances towards metal ion recognition
In addition to recognizing mineral water and lake samples, our platform was used to monitor the salinity of offshore petroleum exploratory well. Using machine learning, the chip also assured simultaneous quantification of the individual concentration of heavy metal ions in mixtures.
Common tools to comprehensively characterize the toxicological profile of two dimensional materials at cell level
This chapter aims to review the latest knowledge and most significant works on the assessment of two dimensional materials potential to induce adverse effects on human health. It highlights the key knowledge achieved so far, not only in terms of negative impact but also solutions identified to make those materials safer or even biocompatible.
The multifunctional magneto-luminescent nanoplatform are biocompatible, showing no acute toxicity to the zebrafish embryos. Following the nanoparticles uptake and biodistribution via Synchrotron X-ray fluorescence imaging, which manifests their bioaccumulation in embryo’s gastrointestinal tract as an integrated form, suggesting new biological and environmental potential applications.
Critical properties and techno-economic aspects of activated carbons from sugarcane bagasse are correlated
Pyrolyzed sugarcane bagasse is pointed out as an economically-competitive alternative raw material to produce activated carbons at broad range of activation conditions that also tune their critical physico-chemical properties for water and air decontamination
New uses for sugarcane bagasse! Its biochar is converted into a substitute for carbon blacks in polymeric composites
Carbonaceous additives were produced from sugarcane bagasse biochar and tested in polyethylene composites, that presented mechanical, thermal and colorimetric properties very close to the ones prepared with the carbon black from fossil fuels
