A near infrared pumped luminescent metal-organic framework thermometer Nd(0.577)Yb(0.423)BDC-F4, with near infrared fluorescence and excellent sensitivity in the physiological temperature range (293-313 K), has been first realized, and might be potentially applied for biomedical systems.
In this work, fluorescent carbon dots (C-dots) were synthesized using a hydrothermal method with <italic>Punica granatum</italic> (pomegranate) fruits as precursors, and were then used as probes for imaging of bacterial ( <italic>Pseudomonas aeruginosa</italic> ) and fungal ( <italic>Fusarium avenaceum</italic> ) cell…
Advanced membrane systems with excellent permeance are important for controllable separation processes, such as gas separation and water purification.
Besides being valuable assets in our daily lives, noble metals (namely, gold, silver, and platinum) also feature many intriguing physical and chemical properties when their sizes are reduced to the nano- or even subnano-scale; such assets may significantly increase the values of the noble metals as functional material…
We report the synthesis of two-dimensional (2D) NiCo2O4 nanosheet-coated three-dimensional graphene network (3DGN), which is then used as an electrode for high-rate, long-cycle-life supercapacitors. Using the 3DGN and nanoporous nanosheets, an ultrahigh specific capacitance (2173 F g(-1) at 6 A g(-1)), excellent rate…
One of the major challenges for nanoparticles to be used as a drug/gene delivery platform is their tendency to aggregate in electrolyte solution (physiological environment). The present work introduced the albumin pre-coating strategy that effectively prevented inorganic layered double hydroxide (LDH) nanoparticles wi…
Recent developments in nanomedicine for the cancer therapy have enabled programmable delivery of therapeutics by exploiting the stimuli-responsive properties of nanocarriers. These therapeutic systems were designed with the relevant chemical and physical properties that respond to different triggers for enhanced antic…
A bottom-up method, using monoethanolamine (MEA) as both a passivation agent and a solvent, has been developed for rapid and massive synthesis of nitrogen-doped carbon dots (N-C-dots) from citric acid under heating conditions. This method requires a relatively mild temperature (170 °C) without special equipment, and a…
Highly fluorescent water-soluble and nitrogen-doped carbon dots (NCDs) were synthesized by a simple one-pot hydrothermal method using citric acid as carbon source and urea as nitrogen source.
A systematic study of the synthesis and characterization of epoxy thermosets derived from ELO cured with different DCAs in the presence of DMAP at 160 °C for 1 h.
Copper nanoparticle (Cu-NP) synthesis has been gaining attention due to its property and applicability. The main objective of the work is to synthesize stable Cu-NP through green synthesis. This work demonstrates the synthesis of Cu-NP by the addition of the acidic chitosan solution to CuSO 4 solution with constant st…
Atomically-thin, inherently 2D semiconductors offer thickness scaling of nanoelectronic devices and excellent response to light for low-power versatile applications. Using small exfoliated flakes, advanced devices and integrated circuits have already been realized, showing great potential to impact nanoelectronics. He…
We report the fabrication of NiO nanoflake-based bifunctional glass electrodes that combine energy storage and electrochromism.
A large variation is observed in induction times measured under equal conditions in 1 ml solutions. Ruling out experimental errors, this variation originates from the nucleation process. The induction time distribution is explained by the stochastic nature of nucleation if the number of nuclei formed is approaching 1…
Magnetocaloric effect (MCE) and thermal conductivity of two gadolinium hydroxides, Gd(OH)3 (1) and Gd2O(OH)4(H2O)2 (2), are investigated. Magnetic studies indicate that both 1 and 2 exhibit antiferromagnetic interaction, and the MCE values for 1 and 2 at 2 K and ΔH = 7 T are 62.00 J kg(-1) K(-1) and 59.09 J kg(-1) K(-…
A one-step way to achieve smart reversible switching between the underwater superoleophobicity and underwater superoleophilicity of femtosecond laser ablated Ti materials.
Citric acid was reacted with α,β-diamines, β-amino thiols and β-amino alcohols to produce fluorescent derivatives of 2-pyridone (QY up to ∼79%). The chemical structures of these compounds were confirmed by analyses of 1D, 2D NMR and ESI-MS data.
Two types of functionalized carbonaceous fibers, <italic>i.e.</italic> , carbon fiber@reduced graphene oxide@manganese dioxide (CF@RGO@MnO <sub>2</sub> ) and CF@thick RGO (CF@TRGO), were successfully prepared for high performance flexible all-solid-state asymmetric supercapacitors.
