Sum Frequency Generation Vibrational Spectroscopy Using Evanescent Waves—Toward Probing Irregular and Complex Surfaces of Mesoscopic-Scale Materials
With the rapid development of materials science, on-demand techniques are highly needed with the capability to characterize materials in the micrometer and nanometer scales. In this work, we show that, by employing a prism geometry, total internal reflection sum frequency generation (SFG) vibrational spectroscopy allows for characterizing mesoscopic materials with irregular or complex surfa...

[Solar Energy Materials and Solar Cells]Construction of nanowire CH3NH3PbI3-based solar cells with 17.62% efficiency by solvent etching technique
1D Nanowire CH3NH3PbI3 thin films have been successfully constructed by solvent etching technique. The etching solution was consisted of a small amount of polar solvent in non-polar solvent, and the roughness of the film can be precisely controlled by the adding amount of polar solvent. A best and repeatable PCE of 17.62% was achieved from the CH3NH3PbI3-based solar cells device with nanowire fi...

【RSC Advances】Facile synthesis of hierarchically porous carbonaceous materials derived from olefin/ aldehyde precursors using silica as templates
Porous carbon is exceptionally useful, but it remains a great challenge to develop a facile route to prepare porous carbon materials with hierarchical structure and enhanced porosity. This work demonstrates a novel synthetic pathway for hierarchical carbonaceous materials (HCM) using isobutene and formaldehyde as carbon precursors via silica templates impregnated with phosphorus. Different from ...

【Materials Letters】Tunable field emission properties of carbon nanotube arrays by engineering Fe catalysts
High-quality carbon nanotube (CNT) arrays composed of nanotubes with different diameters and wall numbers were synthesized by water-assisted chemical vapor deposition (CVD) from engineered Fe catalysts. Interestingly, the distribution of nanotube diameter and wall number broadened over 2.5 times as the catalytic Fe thickness increased. The mean diameter and wall number of nanotubes increased mon...

【Journal of Materials Science】Electromagnetic and microwave absorbing properties of magnetite nanoparticles decorated carbon nanotubes/polyaniline multiphase heterostructures
Magnetite nanoparticles decorated CNTs/PANI multiphase heterostructures were prepared by polymerization of aniline monomer and an additional process of the coprecipitation of Fe2+and Fe3+. Scanning electron microscopy and transmission electron microscopy observation indicated that the monodispersed magnetite nanoparticles were uniformly decorated on the surface of CNTs/PANI. The formation of mag...

【Journal of Materials Science】Nitrogen-doped graphene-supported molybdenum dioxide electrocatalysts for oxygen reduction reaction
A simple one-step pyrolysis strategy has been developed to prepare molybdenum dioxide supported on nitrogen-doped graphene (MoO2/NG) as electrocatalyst for oxygen reduction reactions (ORR). Homogeneous anchoring of MoO2 nanoparticles on nitrogen-doped graphene was achieved for the composite synthesized at 500 °C (MoO2/NG-500). For the first time, the MoO2/NG composite manifests considerable ele...

NIR-I-to-NIR-II fluorescent nanomaterials for biomedical imaging and cancer therapy,Journal of Materials Chemistry B, 2018, 6, 349
Near-infrared (NIR) fluorescence imaging, which affords high imaging resolution owing to deep tissue
penetration of NIR photons, is an attractive imaging modality for both biomedical research and clinical
applications. To further improve the image contrast at increased tissue depth, recently much attention
has been focused on the development of NIR-I-to-NIR-II fluorescence imaging, whic...

117.Creating Quasi Two-Dimensional Cluster-Assembled Materials through Self-Assembly of a Janus Polyoxometalate-Silsesquioxane Co-Cluster
Clusters are an important class of nanoscale molecules or superatoms that exhibit an amazing diversity in structure, chemical composition, shape, and functionality. Assembling two types of clusters is creating emerging cluster-assembled materials (CAMs). In this paper, we report an effective approach to produce quasi two-dimensional (2D) CAMs of two types of spherelike clusters, polyhedral oligo...

【Journal Of Materials Chemistry A】A Review On Noble-Metal-Free Bifunctional Heterogeneous Catalysts For Overall Electrochemical Water Splitting
Production of hydrogen by water splitting is an appealing solution for sustainable energy storage. Development of bifunctional catalysts that are active for both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) is a key factor in enhancing electrochemical water splitting activity and simplifying the overall system design. Here, recent developments in HER–OER bifunct...
