Triboelectric nanogenerators as new energy technology and self-powered sensors – Principles, problems and perspectives
Triboelectrification is one of the most common effects in our daily life, but it is usually taken as a negative effect with very limited positive applications. Here, we invented a triboelectric nanogenerator (TENG) based on organic materials that is used to convert mechanical energy into electricity. The TENG is based…
Nanoparticles for photothermal therapies
The current status of the use of nanoparticles for photothermal treatments is reviewed in detail. The different families of heating nanoparticles are described paying special attention to the physical mechanisms at the root of the light-to-heat conversion processes. The heating efficiencies and spectral working ranges…
Prepare dispersed CIS nano-scale particles and spray coating CIS absorber layers using nano-scale precursors
In this study, the Mo-electrode thin films were deposited by a two-stepped process, and the high-purity copper indium selenide-based powder (CuInSe2, CIS) was fabricated by hydrothermal process by Nanowin Technology Co. Ltd. From the X-ray pattern of the CIS precursor, the mainly crystalline phase was CIS, and the alm…
Tuning the structure and function of metal–organic frameworks via linker design
Metal-organic frameworks (MOFs) are constructed from metal ions/clusters coordinated by organic linkers (or bridging-ligands). The hallmark of MOFs is their permanent porosity, which is frequently found in MOFs constructed from metal-clusters. These clusters are often formed in situ, whereas the linkers are generally…
Metal–organic frameworks for artificial photosynthesis and photocatalysis
Solar energy is an alternative, sustainable energy source for mankind. Finding a convenient way to convert sunlight energy into chemical energy is a key step towards realizing large-scale solar energy utilization. Owing to their structural regularity and synthetic tunability, metal-organic frameworks (MOFs) provide an…
Earth-abundant cocatalysts for semiconductor-based photocatalytic water splitting
Photocatalytic water splitting represents a promising strategy for clean, low-cost, and environmental-friendly production of H2 by utilizing solar energy. There are three crucial steps for the photocatalytic water splitting reaction: solar light harvesting, charge separation and transportation, and the catalytic H2 an…
Applications of metal–organic frameworks in heterogeneous supramolecular catalysis
This review summarizes the use of metal-organic frameworks (MOFs) as a versatile supramolecular platform to develop heterogeneous catalysts for a variety of organic reactions, especially for liquid-phase reactions. Following a background introduction about catalytic relevance to various metal-organic materials, crysta…
Lead-free organic–inorganic tin halide perovskites for photovoltaic applications
Perovskite solar cells based on abundant low cost materials promise to compete on performance with mainstream PV. Here we demonstrate lead-free perovskite solar cells, removing a potential barrier to widespread deployment.
Luminescent metal–organic frameworks for chemical sensing and explosive detection
Metal-organic frameworks (MOFs) are a unique class of crystalline solids comprised of metal cations (or metal clusters) and organic ligands that have shown promise for a wide variety of applications. Over the past 15 years, research and development of these materials have become one of the most intensely and extensive…
Formamidinium lead trihalide: a broadly tunable perovskite for efficient planar heterojunction solar cells
Perovskite-based solar cells have attracted significant recent interest, with power conversion efficiencies in excess of 15% already superceding a number of established thin-film solar cell technologies. Most work has focused on a methylammonium lead trihalide perovskites, with a bandgaps of ∼1.55 eV and greater. Here…
Connecting thermoelectric performance and topological-insulator behavior: Bi2Te3 and Bi2Te2Se from first principles
Thermoelectric performance is of interest for numerous applications such as waste heat recovery and solid state energy conversion, and will be seen to be closely connected to topological insulator behavior.In this context we here report first principles transport and defect calculations for Bi2Te2Se in relation to Bi2…
XPS/ToF-SIMS characterization of TiO2 supported Au nanoparticles: Effect of catalytic CO oxidation
X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) are employed for a comparative study of the surface composition and electronic structure of an Au/TiO2 catalyst in the asprepared state and after using it in the reaction of CO oxidation at room temperature. As found,…

My Friend “ELASTOMERS” for 40 years
The characteristics of filler gel developed in the silica filled rubber systems were described in relation to the carbon gel. Two kinds of filler gel were considered. The one is that the filler gel corresponds to a rubber component entrapped within a secondary structure formed by silica particles (agglomerates), which…
