Gadolinium(<sc>iii</sc>) chelate-functionalized carbon quantum dots having good magnetic resonance response and photoluminescence properties were prepared, which can be used for multimodal imaging.
A precise probe that can be applied in a variety of situations, such as both environmental sensor and vitro imaging, is very attractive promising. Here, we firstly reported kind nitrogen-rich carbon dots (N-CDots) growing during hydrothermal treatment, which emit bright colorful fluorescence utilized reliable for Ferric ions (Fe3+) detection bio-imaging. The nitrogen/carbon molar ratio (N/C) N-CDots high 39.9%. It the nitrogen content provides quantum yield (at excitation wavelength 365 nm,...
Abstract To solve the problem that self‐generated proppant in fractures grows slowly and cannot support time, nano‐graphite (NG) was introduced into a phase change liquid (PCL) composed of “styrene‐divinylbenzene (SDB)” resulting proppants were constructed with high growth speed. The NG/PCL started transition from to solid after 8 min at about 55°C wellbore section, completed for only 2.5 constant temperature 65°C fracture. Moreover, due thermal conductivity heterogeneous nucleation NG...
Abstract Zero‐dimensional nitrogen‐doped carbon dots (N‐CDs) have been proved effective when introduced into the polymerization system of aniline as hard template to synthesis small‐sized, monodisperse and highly conductive N‐CDs/PANI (N‐CDs/PANI) nanocomposites, which were then added acrylic (AC) resin produce coatings with excellent corrosion resistance antifouling performances in this paper. Compared PANI, did show remarkably improved anticorrosion properties. The protection efficiency AC...
The commercially acquired aqueous solution of “carbon quantum dots” sample was evaluated by optical absorption and fluorescence emission methods; in reference to dispersed small carbon nanoparticles representative dots prepared from chemical functionalization the nanoparticles. results suggest a very low content that is associated with nanoscale particles/domains as-supplied sample; likely significant contamination dye-like species/mixtures. In absence any information on synthesis history...
A facile synthetic strategy, which leads to a high-performance Gd<sup>3+</sup>-based MRI contrast agent (Gd<sup>3+</sup>@CGO), is developed using graphene oxide as nanocarrier.
Fullerene cages are known as being able to participate in radical initiated copolymerization reactions with vinyl monomers for polymer-functionalized fullerenes. In this work, poly(N-vinylcarbazole) (PVK) was selected a representative of electronic polymers the functionalization fullerene C60 by same reaction yield PVK-C60. Similarly found that small carbon nanoparticles could also be surface-functionalized and -passivated attached PVK polymers, which structurally adhering general definition...
Carbon dots (CDots) are small carbon nanoparticles with effective surface passivation accomplished mostly via organic functionalization. In this study, the largely amorphous were copolymerized N-vinylcarbazole in microwave-assisted radical reactions. The copolymers thus formed structurally equivalent to individual each surface-functionalized by multiple poly(N-vinylcarbazole) (PVK) segments, denoted as PVK-CDots. Their electronic transitions and photoexcited state properties, including...
Abstract Ultra‐low‐density proppants are of great significant in slick water fracturing system, but the polymer composite microspheres can hardly promise quality oil and gas due to their poor hydrophobicity. To address issue, we prepared several types modified styrene‐divinyl benzene copolymer (MSDBs) with long‐term durable hydrophobicity high strength, including O‐MSDBs (hydrophobic MSDBs), LO‐MSDBs (long‐time hydrophobic CO‐MSDBs (coated O‐MSDBs) on basis a molecular structure...
With residual double bonds contents increasing, the binding energy of Pt/SDB increased, which made catalytic activity and stability enhanced.
An ideal proppant showing super-hydrophobicity and enough strength to bear high closure stress is revolutionary for the effective exploration of gas or oil in shale. Here, proppants were obtained by wrapping specially treated phenol formaldehyde resins around cover traditional ceramsites. The resin coating patterned with innumerable fluorine-modified silica nanoparticles, whose thickness controllable. Benefitting from low surface energy fluorine, nano-roughness structures nano-silica,...
