The prevalence of surface functionalized carbon dots (CDs) with intriguing fluorescence properties has given a new dimension to the field of bioimaging and is perceived as a promising alternative to quantum dots (QDs).
Carbon aerogels with large open pores and high surface area are fabricated via pyrolysis of a readily available natural resource, e.g., bacterial nanocellulose (BNC) aerogels. Freeze-drying of the BNC hydrogels is used to preserve the 3D open network structure upon calcination whereas using Fe(III) improves the yield…
Polyaniline (PANI)/graphene thermoelectric (TE) nanocomposite films with three types of graphene have been prepared by a solution-assistant dispersing method. The graphene nanoplates were aligned in the PANI matrix in the direction parallel to the substrate. The structural defects and oxygen content in the graphene ha…
Val-TPE shows aggregation-induced emission, aggregation-induced circular dichroism, circularly polarized luminescence and the capacity to self-assemble into helical nanofibers.
Single-crystalline NiO nanosheet arrays on Ni foam as a binder-free electrode for high-performance supercapacitors, fabricated by a facile and cost-effective hydrothermal approach, exhibit a high specific capacitance, good rate capability, and excellent cycling stability.
Silica has been extracted from rice husk, employing a simple extraction for preparing poly(lactic acid) bio-composites with different filler contents.
Three-dimensional porous composites of reduced graphene oxide and polyaniline prepared by electro-codeposition exhibited much higher areal specific capacitances and greatly improved rate capability compared with those of their individual components.
The formation mechanism of red phosphor K 2 SiF 6 :Mn 4+ free of manganese oxides has been discussed based on detailed experimental results. Significant improvements in the luminescence efficiency make it a good candidate for applications in “warm” white LEDs.
The electrochemical production of H2O2 from O2 catalyzed by [Au25(SC12H25)18] was studied as a function of the charge state (-1, 0 and +1). Maximum H2O2 production (∼90%) was obtained from the negatively charged clusters (Au25(-)) due to the efficient electron transfer from the anionic Au25(-) cluster into the LUMO (π…
In modern times, with the rapid development of technology, science and economy, applications of electromagnetic (EM) wave absorption in both commercial and military fields have increased. Meanwhile, the problems brought by EM wave absorption have gradually become obvious, such as signal interference, back-radiation of…
Here we propose, for the first time, a new and green ethanol-thermal reaction method to synthesize high-quality and pure thiophene-sulfur doped reduced graphene oxide (rGO), which establishes an excellent platform for studying sulfur (S) doping effects on the physical/chemical properties of this material. We have quan…
A supercapacitor electrode of porous urchin-like MnCo 2 O 4.5 hierarchical architectures demonstrated an outstanding rate capability and excellent cycling stability, which could be considered as a potential mixed transition metal oxide material for high-rate supercapacitors.
In this work, we present a facile two-step hydrothermal method with a successive annealing treatment to integrate two ternary metal oxides (NiCo2O4 and CoMoO4) into unique core/shell nanowire arrays (NWAs) on Ni foam as advanced binder-free electrodes for the first time. In addition, a possible growth mechanism for th…
The effects of different local crystalline structures of two-dimensional (2D) MoS 2 sheets on the performance of organic solar cells (OSCs) are studied, providing new insights towards high-performance devices.
This work analyzes the differences between a ‘photoanode first’ and a ‘photocathode first’ 2-photon water splitting device.
Hydrogels formed by ultrashort peptides are emerging as cost-effective materials for cell culture. However, L-peptides are labile to proteases, while their D-isomers are thought to not support cell growth as well. In contrast, the self-assembly behaviour and biological performance of heterochiral peptides (i.e., made…
We give a review of the theoretical approaches for predicting spectral phonon mean free path and thermal conductivity of solids. The methods can be summarized into two categories: anharmonic lattice dynamics calculation and molecular dynamics simulation. In the anharmonic lattice dynamics calculation, the anharmonic f…
This perspective demonstrates the inapplicability of equilibrium partition coefficients as fate descriptors for nanoparticles.
BACKGROUND: To assess the risk of all nanomaterials (NMs) on a case-by-case basis is challenging in terms of financial, ethical and time resources. Instead a more intelligent approach to knowledge gain and risk assessment is required. METHODS: A framework of future research priorities was developed from the accorded o…
Lanthanide-doped upconversion nanoparticles (UCNPs) have recently shown great promise in photodynamic therapy (PDT). Herein, we report a facile strategy to fabricate an efficient NIR-triggered PDT system based on LiYF4:Yb/Er UCNPs coupled with a photosensitizer of a β-carboxyphthalocyanine zinc (ZnPc-COOH) molecule vi…
