The two-step mechanism of nucleation of crystals in solutions posits that the formation of crystal nuclei occurs within structures of extended lifetimes, in which the nucleating solute is at high concentration. The validity of this mechanism has been demonstrated for proteins, small-molecule organic and inorganic mate…
Double-shelled Co/C/polyaniline (Co/C/PA) nanocomposites were prepared by combining the arc-discharge process and in situ chemical oxidative polymerization reaction.
), the poly(ethylene glycol) modified Fe-PDA NPs (termed as PEG-Fe-PDA NPs) exhibited pH-activatable magnetic resonance imaging (MRI) contrast and high photothermal performance. The combination of a small dimension and the pH-activatable MRI contrast can greatly facilitate tumor accumulation and increase the tumor ima…
Electromagnetic interference shielding (EMI) materials were designed using PC (polycarbonate)/SAN [poly(styrene-co-acrylonitrile)] blends containing few-layered graphene nanosheets decorated with nickel nanoparticles (G-Ni). The graphene nanosheets were decorated with nickel nanoparticles via the uniform nucleation of…
Liquid-infused surfaces display advantageous properties that are normally associated with conventional gas-cushioned superhydrophobic surfaces. However, the surfaces can lose their novel properties if the infused liquid drains from the surface. We explore how drainage due to gravity or due to an external flow can be p…
This study attempts to synthesize magnetite nanoparticles from a high purity natural iron oxide ore found in Panvila, Sri Lanka, following a novel top‐down approach. Powder X‐Ray diffraction, elemental analysis, and chemical analysis data confirmed the ore to be exclusively magnetite with Fe2+ : Fe3+ ratio of 1 : 2. S…
Developing new materials for electrochemical supercapacitors with higher energy density has recently gained tremendous impetus in the context of effective utilization of renewable energy. Herein, we report a simple one-pot synthesis of bundled nanorods of Cu(OH)2 embedded in a matrix of reduced graphene oxide (Cu(OH)2…
This review highlights fundamental concepts and synthetic strategies of SMMs and selected examples of 3d, 4f, 5f and mixed 3d–4f, 4d–5d and 3d–5f based SMMs are discussed.
In this work we designed a MoS2 nanoplate-based nanoprobe for fluorescence imaging of intracellular ATP and photodynamic therapy (PDT) via ATP-mediated controllable release of (1)O2. The nanoprobe was prepared by simply assembling a chlorine e6 (Ce6) labelled ATP aptamer on MoS2 nanoplates, which have favorable biocom…
Hole doping leads to an efficient photo-induced interfacial charge transfer from MOFs to TiO 2 and thereby the MOFs can harvest solar radiation to generate electricity.
The sessile drop method is an easy and fast method used to measure the contact angle between solids and liquids. The value of the contact angle is used in surface characterization, in particular the wettability of solid surfaces by the liquid and to calculate the surface free energy. In this work, we study the effects…
Nitrogen-doped hierarchical hollow nest-like carbon nanostructures, fabricated from glucose with a novel template-free method, exhibited outstanding supercapacitive performances.
The healing phenomenon of metallopolymers is studied in detail and the dependency of the chosen metal salt is provided. Furthermore, a correlation between the supramolecular bond life time and the healing behavior could be revealed.
We present a systematic study of the key synthetic parameters that control the growth of Fe–triazole spin-crossover nanoparticles and the effect of this size modulation on the spin transition.
This article describes the synthesis and characterization of ZnO nanoring embedded graphene nanoribbons. Patterned holes (mesopore dia.) in graphene nanoribbons are chemically generated, leading to a high density of the edge planes. These planes carry negatively charged surface groups (like -COOH and -OH) and therefor…
The presence of oxygen vacancies and synergetic interaction between Ce and Mn were responsible for superior Hg 0 oxidation performance of CeO 2 –MnO x compared to pure CeO 2 and MnO x .
Ultrasmall and water dispersible SrF 2 :Tm 3+ ,Yb 3+ upconverting nanoparticles show intense ultraviolet emissions after 980 nm excitation.
Attempts to make a diamino disulfonic acid derivative of an aza-BODIPY showed it was difficult to add BF2 to a disulfonated azadipyrromethene, and sulfonation of an aza-BODIPY resulted in loss of the BF2 fragment. We conclude the electron-deficient character of aza-BODIPY dyes destabilizes them relative to BODIPY dyes…
Poly(cyclotriphosphazene- co -4,4′-sulfonyldiphenol) (PZS) submicro-spheres were easily prepared, which exhibited a selective adsorption and separation of dyes that can be classified as Lewis acids and/or Brønsted acids by acid–base interactions.
Nitrite ions are shown to have significant influence on the selectivity of the photocatalytic oxidation of methane to methanol. An almost complete inhibition of undesired CO2 has been achieved with BiVO4 in the presence of a low concentration of nitrite, which might act both as a UV filter and as a hydroxyl radical sc…
