The role of hydrophilic groups in acid intercalated GO for proton conduction has been justified. The higher extents of adsorbed water due to the presence of hydrophilic groups are primarily responsible for offering enhanced proton conductivity.

Reduced graphene oxide–transition metal hybrids were accomplished to deposit a p-type semiconductor films on conductive glass for acetaldehyde sensing.

Insertion of 3-hydroxypropanesulfonicacid (HPS) in the graphene oxide (GO) interlayer results in high proton conductivity (10 -10 S cm ), owing to an improvement in oxygen content, interlayer distance and water absorbing capacity. This result indicates that hydroxyalkylsulfonicacids can be perfect guest molecules for improving the proton conductivity of carbon materials.

An antimalarial drug artesunate (ATS) was encapsulated in both functionalized MCM-41 and ordinary MCM-41 with an excellent loading capacity and sustained release behavior for possible biomedical applications.

Within the nanopores, junctions and interlayer void space (IVS) in graphene oxide film (GOf), we report that IVS function as the key semipermeable site during sieving. The GOf could filter only dye molecules having nanometer-ranged dimensions. Tinier hydrated ions with angstrom-ranged dimensions couldn't be sieved by GOf. Nature and extent of this molecular sieving property have been justified by observing sieving efficacy and flow times for aqueous solutions of dyes, inorganic salts and their mixtures. GOf also could separate the dyes from mixtures with salts. The flow time followed the trend as: mixtures > salt solutions > dye solutions. PXRD data reveal entering of dye molecules at IVS during sieving. Obviously, a part of dye molecules leaking through the nanopores and junctions of GOf, finally become trapped at the IVS. IVS, therefore has been recognized as the key semipermeable site for molecular sieving in GO. With exploring the insight features of molecular sieving in GOf, this report clearly indicates that IVS needs to be tuned to adopt GOf for various analytical aspects including water purification, desalination and organic inorganic separation.[a] Dr.
