A proof of principle is presented for the rational design of metal clusters functionalized with hydrophilic, chiral ligands. A colloidal method is used to prepare "unprotected" metal clusters of well-defined size that are subsequently functionalized in a separate step with hydrophilic, chiral ligands. As clusters from the same batch are functionalized with different organic molecules while the ...

• High SOD activity of Cu(II) complexes upon covalent immobilization in aerogel. EPR and SANS show the molecular level separation data formation new coordination modes Chemical environment, mode, alter reactivity complexes. mimetic aerogels form stable microparticles water. The copper(II) 1,4,7,10-tetraazacyclododecane (cyclen) 1,4,8,11- tetraazacyclotetradecane (cyclam) were covalently immobil...

The use of physical paper is often preferred due to its unique properties that improve various aspects reading. However, digital media and information are more engaging, diverse, up date, thereby challenging the existence in our everyday life. By combining two types a seamless way, interactivity multimedia content can complement reading experience, maintaining feel books. current state art addr...

Two-dimensional metal carbides and nitrides–MXenes?represent a group of materials which have attained growing attention over the last decade due to their chemical versatility, making them highly promising in areas such as energy storage, superconductivity, heterogenous catalysis. Surface terminations are natural consequence MXene synthesis, conventionally consisting O, OH, F. However, recent st...

A gold nanorod (AuNR) based colorimetric probe was reported for the rapid and selective detection of Cu(2+) ions. The probe was fabricated by functionalizing cysteine (Cys) onto AuNR (Cys-AuNR) with an aspect ratio of 2.3. The strong coordination of Cu(2+) with cysteine resulted in a stable Cys-Cu-Cys complex, and induced the aggregation of the colloidal nanorods along with a rapid colour chang...

The fabrication of a gas nanosensor for detecting ammonia gas in air that is unaffected by humidity is demonstrated. On functionalizing single-walled carbon nanotube (SWNT) networks with a precise amount of camphorsulfonic-acid-doped polyaniline (PANI(CSA)), the opposite electrical resistance responses of the CSA-doped PANI and SWNTs to humid air effectively canceled each other, thereby elimina...
