A DPP molecule has appropriate energy levels and bipolar charge-transport properties for both donor and acceptor in OSCs.
The necessity of high performance materials has become latent in high technology sectors such as aerospace, automotive, renewable energy, nuclear engineering and sports. The expanding impact on future manufacturing of the EU waste management legislation and increasing price of current waste management methods stress t…
The use of granular electrodes in Microbial Fuel Cells (MFCs) is attractive because granules provide a cost-effective way to create a high electrode surface area, which is essential to achieve high current and power densities. Here, we show a novel reactor design based on capacitive granules: the fluidized capacitive…
It is of interest to create superoleophobic surfaces that exhibit high oil contact angle, low contact angle hysteresis, high wear resistance, antismudge properties, and optical transparency for industrial applications. In the superoleophobic surfaces developed to date, the mechanical durability data is lacking. By dip…
X-ray photoelectron spectroscopy (XPS) is a nearly universal method for quantitative characterization of both organic and inorganic layers on surfaces. When applied to nanoparticles, the analysis is complicated by the strong curvature of the surface and by the fact that the electron attenuation length can be comparabl…
Pure nanodrugs (PNDs), nanoparticles consisting entirely of drug molecules, have been considered as promising candidates for next-generation nanodrugs. However, the traditional preparation method via reprecipitation faces critical challenges including low production rates, relatively large particle sizes, and batch-to…
High Resolution Image Download MS PowerPoint Slide Poly(norbornene)- g -poly(4-methacryloyloxy-2,2,6,6-tetramethylpiperidin-1-oxyl) (PNB- g -PTMA) was prepared by a grafting-through approach based on anionic polymerization of 4-methacryloyloxy-2,2,6,6-tetramethylpiperidin-1-oxyl using a norbornene-substituted diphenyl…
Defects are unavoidable and usually originate exotic properties in realistic materials. One of the most fundamental defect-induced properties of a solid surface is its reactivity to adsorbed species. Defects in anodes of electrochemical cells for water splitting could therefore play a critical role in the interatomic…
Plasmonic nanostructures are synthesized by decorating B- or N-doped carbon nanotubes (CNTs) with Au nanoparticles. While the plasmonic nanoparticles promote exciton generation and dissociation, the B- and N-doped CNTs enable charge-selective transport enhancement in the organic active layer. Such concurrent enhanceme…
In this study, we report the utilization of solution-processed high electrical conductive [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) combined with solution-processed TiO2 as the electron transport layer (ETL) to overcome extremely low electrical conductivity of solution-processed TiO2 ETL in planar heterojunc…
Auxetic honeycombs have proven to be an attractive advantage in actual engineering applications owing to their unique mechanical characteristic and better energy absorption ability. The in-plane dynamic crushing behaviors of the honeycombs with various cell-wall angles are studied by means of explicit dynamic finite e…
We evaluate and compare the sensitivity of gold nanodisks on silica substrates and nanoholes made in silica-supported gold films, two of the most common sensor structures used in plasmonic biosensing. An alumina overcoat was applied by atomic layer deposition (ALD) to precisely control the interfacial refractive index…
Near-infrared (NIR) photothermal therapy has developed very quickly in recent years. However, its clinical applications are hindered by many practical problems, such as low accumulation in tumors, high laser power density and high biotoxicity in vivo . Herein, a versatile system combining chemotherapy with phototherma…
Herein, we report the targeted synthesis and solid state assembly of a novel triazine-based [4+6] organic molecular cage. The tetrahedral cage features a large cavity (∼2070 Å(3)), and after desolvation, the resultant material exhibits a high Brunauer-Emmett-Teller surface area of 1181 m(2) g(-1) and also features sel…
This article addresses the intriguing hydrogen-abstraction (H-abstraction) and oxygen-transfer (O-transfer) reactivity of a series of nonheme [Fe(IV)(O)(TMC)(Lax)](z+) complexes, with a tetramethyl cyclam ligand and a variable axial ligand (Lax), toward three substrates: 1,4-cyclohexadiene, 9,10-dihydroanthracene, and…
There is much evidence that nucleation of liquid droplets from vapor as well as nucleation of crystals from both solution and vapor occurs preferentially in surface defects such as pits and grooves. In the case of nucleation of solid from liquid (freezing) the situation is much less clear-cut. We have therefore carrie…
A new Mo-doped LiV 3 O 8 nanorod-assembled nanosheet was prepared by a simple hydrothermal method and subsequent calcination. Its unique structure demonstrates a maximum discharge capacity of 269 mAh g −1 at 300 mA g −1 within 4.0-2.0 V, and excellent rate and cycle performance for Li-ion batteries.
We investigate the development of metre long negative discharges and focus on their x-ray emissions. We describe appearance, timing and spatial distribution of the x-rays. They appear in bursts of nanosecond duration mostly in the cathode area. The spectrum can be characterized by an exponential function with 200¿keV…
The remarkable rise of organometal halide perovskites as solar photovoltaic materials has been followed by promising developments in light-emitting devices, including lasers. Here we present unique insights into the processes leading to photon emission in these materials. We employ ultrafast broadband photoluminescenc…
High-energy and high-power Li-ion batteries have been intensively pursued as power sources in electronic vehicles and renewable energy storage systems in smart grids. With this purpose, developing high-performance cathode materials is urgently needed. Here we report an easy and versatile strategy to fabricate high-rat…
