Synthesis of pure nano Cr2O3 from chromite ore by a novel method and investigation of its composites with bentonite for their photocatalytic properties

Optimizing nanofluid additives for enhanced thermophysical properties in anionic crude oil for EOR applications

“…Nanoparticles within nanosuspensions typically range in size from 1 to 100 nm, and this small size amplifies their effective surface area and notable surface‐area‐to‐volume ratio, [ 6–12 ] impacting fluid properties like heat transfer, viscosity, [ 13 ] and particle activity on surfaces. [ 14,15 ] Moreover, nanoparticles possess unique physicochemical and mechanical properties and exhibit resilience against degradation, [ 16–22 ] especially in oil and gas reservoirs characterized by high salinity and temperature. [ 23 ]…”

Investigation into the elimination of nitrates using nano γ-alumina and magnetite-alumina nanocomposite adsorbents synthesized through different methods and precursor materials

“…Furthermore, nano-adsorbents have been the subject of meticulous scrutiny, gaining ascendancy owing to their propitious attributes, notably including an expansive surface area, inherent self-assembly prowess, and markedly heightened reactivity [22][23][24] . While nanomaterials are commercially procurable 25,26 , their synthesis affords a ner degree of tailoring for requisite special characterizations 27 . Various methodologies, such as mechanical milling, sol-gel processes, hydrothermal modalities, chemical reduction, ultrasound, precipitation, and microwave-assisted preparation, have been invoked in the synthesis of metallic nanoparticles [28][29][30][31][32][33] .…”

Nitrate removal study of synthesized nano γ-alumina and magnetite-alumina nanocomposite adsorbents prepared by various methods and precursors

“…Furthermore, nano-adsorbents have been the subject of meticulous scrutiny, gaining ascendancy owing to their propitious attributes, notably including an expansive surface area, inherent self-assembly prowess, and markedly heightened reactivity 22 – 24 . While nanomaterials are commercially procurable 25 , 26 , their synthesis affords a finer degree of tailoring for requisite special characterizations 27 . Various methodologies, such as mechanical milling, sol–gel processes, hydrothermal modalities, chemical reduction, ultrasound, precipitation, and microwave-assisted preparation, have been invoked in the synthesis of metallic nanoparticles 28 – 33 .…”
