Among different carbon nanomaterial foam-filled polymer composites, graphene-based foam gives superior specific shielding effectiveness when compared to typical metals.
. Furthermore, the uptake of HA capsules is a stiffness-dependent process, with slower and less cellular internalization observed with increasing capsule stiffness. Nevertheless, regardless of the stiffness, all internalized capsules are deformed and located in the lysosomes. These findings offer insights into the inf…
Solid state asymmetric supercapacitors are fabricated by employing conducting polymers, such as polyaniline and poly(3,4-ethylenedioxythiophene) as positive and negative electrodes, respectively.
The effect of acid treatment towards the degree of defibrillation. Rapid uptake of cationic dye. Hemicellulose responsible for dye uptake.
. The probe exhibits significant advantages, such as no self-quenching at high concentrations, a large Stokes shift (190 nm) and high specificity to β-galactosidase with an excellent light-up ratio of 820 fold. Moreover, thanks to its good retention in living cells, the application of SA-βGal for the imaging of cellul…
In this paper, using CoS@NiCo 2 S 4 as an example, we report the successful design and synthesis of a novel hierarchical core/shell metal sulfide with conductive CoS on nickel foam via a facile ion exchange process.
We report a strategy for developing π-electronic covalent organic frameworks as heterogeneous catalysts that enable the use of columnar π-walls as catalytic beds to facilitate organic transformations in their one-dimensional open channels. The π-frameworks exhibit outstanding catalytic activity, promote Diels-Alder re…
Here we report a two-step programmable reduction of graphene oxide (GO) which was synthesized by oxidation of graphite.
Boron nitride nanosheets (BNNSs) with micron-sized edges were prepared in high yields by direct exfoliation of bulk hexagonal boron nitrides using ionic liquids (ILs). The ILs strongly attached onto BNNS surfaces, and dramatically enhanced the exfoliation, giving highly concentrated BNNS dispersions (∼1.9 mg mL(-1)) a…
This is a comprehensive review on the toxicity of metal oxide nanomaterials regarding their environmental interactions at the nano–bio–eco interface.
Experimental evidence for high temperature diffusion of hydrogen into the interlayer space of graphite is provided. This process is discussed as a possible method for the rapid production of high-quality, inexpensive graphene in large quantities, which could lead to the widespread application of graphene. It was found…
Conventional chemotherapy for the treatment of cancer has limited specificity when administered systemically and is often associated with toxicity issues. Enhanced accumulation of polymeric nanocarriers at a tumor site may be achieved by passive and active targeting. Incorporation of trigger responsiveness into these…
Three air-stable tetrahedral manganese(ii) dihalide complexes [MnX2(DPEPO)] (DPEPO = bis[2-(diphenylphosphino)phenyl]ether oxide; X = Cl, Br and I) were prepared. All of the obtained compounds were structurally characterized by single-crystal X-ray diffraction analyses, which reveal that they crystallize in centrosymm…
A new graphene/Cu nanoparticle composite was prepared via the in situ reduction of GO in the presence of Cu nanoparticles which was then utilized as a sacrificing template for the formation of graphene electrodes for supercapacitors.
A metal-free aromatic compound with a chiral carbon sandwiched between a donor moiety and an acceptor moiety was designed. Under thermally activated delayed fluorescence, the compound displayed a photoluminescence quantum yield of 26%, and showed circularly polarized luminescence with a dissymmetry factor of 10(-3).
Understanding the interaction of proteins with charged diamond nanoparticles is of fundamental importance for diverse biomedical applications. Here we present a thorough study of protein binding, adsorption kinetics and structure on strongly positively (hydrogen-terminated) and negatively (oxygen-terminated) charged n…
Graphene quantum dots (GQDs) have attracted tremendous attention for biological applications. We report the first study on cytotoxicity and genotoxicity of GQDs to fibroblast cell lines (NIH-3T3 cells). The NIH-3T3 cells treated with GQDs at dosages over 50 μg mL(-1) showed no significant cytotoxicity. However, the GQ…
Carbon dots with solid-state fluorescence have been synthesized and applied for light emitting devices and bioimaging.
A facile and cost-effective solvothermal method is described for the synthesis of mesoporous NiCo 2 O 4 –rGO electrode material using PVP polymeric surfactant for supercapacitor application.
The bonding of benzotriazole-an outstanding corrosion inhibitor for copper-on reduced and oxidized copper surfaces is discussed on the basis of density functional theory (DFT) calculations. Calculations reveal that benzotriazole is able to bond with oxide-free and oxidized copper surfaces and on both of them it bonds…
