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…
Nanotechnology is having a tremendous impact on our society. However, societal concerns about human safety under nanoparticle exposure may derail the broad application of this promising technology. Nanoparticles may enter the human body via various routes, including respiratory pathways, the digestive tract, skin cont…
Nanophotonics, which is mainly the study of the behavior of light-matter interaction at the wavelength scale, has developed into one of the most important branches in optics-related disciplines. Utilizing organic functional molecules as the building blocks of nanophotonic materials and devices has great potential due…
Polydopamine particles were used as fillers for constructing multifunctional composites for the first time.
We report synthesis of ZrO₂ nanoparticles (NPs) using microwave assisted chemical method at 80°C temperature. Synthesized ZrO₂ NPs were calcinated at 400°C under air atmosphere and characterized using FTIR, XRD, SEM, TEM, BET, and EDS for their formation, structure, morphology, size, and elemental composition. XRD res…
The PVDF/ZnO composites were prepared by a simple hot-press method. The dielectric behavior of the composites was improved at a lower percolation threshold. For the composites with a filler content of 10 wt%, the reflection loss appears as two peaks that can reach −15.90 dB at 6.60 GHz and −25.44 dB at 16.48 GHz.
Newly synthesised {Cr III 2 Dy III 2 } single molecule magnets reveal that the size of the anisotropy barrier is related to the strength of the magnetic exchange interaction in the complex.
The aim of the tutorial review is to show that any crystallization from solution is guided by stable or metastable equilibria and thus can be rationalized by using phase diagrams. Crystallization conducted by cooling, by evaporation and by anti-solvent addition is mainly considered. The driving force of crystallizatio…
Nitrogen-doped carbon quantum dots (N-CQDs) are prepared via one-step hydrothermal processing using citric acid and linear-structured polyethyleneimine (LPEI) polymer as raw materials. The LPEI serves not only as a nitrogen source for N-doping but also as a surface-passivation agent for surface modification. The as-ob…
Recent uses of titanium dioxide (TiO2) have involved various applications which include the food industry. This study aims to develop TiO2nanoparticle-coated film for potential food packaging applications due to the photocatalytic antimicrobial property of TiO2. The TiO2nanoparticles with varying concentrations (0–0.1…
In this paper, we demonstrate the tunable T1 and T2 contrast abilities of engineered iron oxide nanoparticles with high performance for liver contrast-enhanced magnetic resonance imaging (MRI) in mice. To enhance the diagnostic accuracy of MRI, large numbers of contrast agents with T1 or T2 contrast ability have been…
The PVDF/RGO composites synthesized by a thermal reduction process exhibit high values of reflection loss and excellent dielectric properties with low filler loading.
Crosslinked polyaniline was synthesized via chemical oxidative copolymerization to achieve improved electrochemical performance.
A simple, facile and green hydrothermal method was developed in the synthesis of water-soluble nitrogen-doped carbon dots (N-CDs) from streptomycin. The as-prepared N-CDs displayed bright blue fluorescence under the irradiation of UV light, together with a high quantum yield of 7.6% and good biocompatibility as demons…
Effect of dwell time on mean particle size calculation for 250 000 particles per mL of 60 nm Au NPs nebulized at 300 μL min −1 .
Case study-1 (diverse metal core NPs); case study-2 (similar metal core NPs); case study-3 (metal oxide NPs); case study-4 (surface modified multi-walled CNTs); case study-5 (fullerene derivatives).
An RGO/CNT/NiO hybrid material shows extremely high capacity and cycling performance due to the less aggregation of RGO/NiO caused by the addition of CNTs.
Copper sulfide semiconductors made from earth-abundant elements have an optical absorption edge at ca. 1.2 eV, nearly ideal for solar energy harvesting. We report the growth and formation mechanism of vertically oriented arrays of copper sulfide nanostructures formed by electrochemical anodization. Key parameters that…
Field induced single-molecule-magnet behaviour is observed for both a heterodinuclear [ZnDy(L(-))2](3+) complex (1) and a mononuclear [Dy(HL)2](3+) complex (2), with effective energy barriers of 83 cm(-1) and 16 cm(-1), respectively. Insights into the relaxation mechanism(s) and barrier heights are provided via ab ini…
Iron oxide nanoparticles (IONPs) occupy a privileged position among magnetic nanomaterials with potential applications in medicine and biology. They have been widely used in preclinical experiments for imaging contrast enhancement, magnetic resonance, immunoassays, cell tracking, tissue repair, magnetic hyperthermia a…
