In this paper, the luminescent complex Eu(3-thenoyltrifluoroacetonate)3 was integrated with Fe3O4 and gold (Au) nanoparticles to form a multifunctional nanocomposite, Fe3O4/Au/Eu(TTA)3 (FOASET NC), for dual magnetic-photothermal therapy biomedical imaging. Upon functionalization amine-NH2, FOASET NC exhibits small size of 60-70 nm strong, sharp emission at λmax = 614 nm, enhanced by surface plasmon resonance (SPR) Au that provided an effective label HT29 colorectal cancer cells fluorescence...
Abstract The Eu 3+ ‐doped GdPO 4 nanoparticles were prepared via a straightforward combustion method using urea as fuel and nitrates precursor. X‐ray powder diffraction patterns, infrared spectrum (IR), HR‐TEM, photoluminescence (PL), phonon sideband excitation (PLE) researched. There is phase transition from the hexagonal into monoclinic when calcined temperature over 700 °C. All of phosphors have similar morphology average diameters for are 20–30 nm. Under at 273 nm, :Eu powders showed red...
In this report, GdPO 4 ·nH 2 O and Tb 3+ -doped nanorods@silica-NH conjugated with IgG antibody were synthesized by applying hydrothermal, sol-gel, coprecipitation methods successively. The effects of /Gd molar ratios reactants on the size, morphology, luminescence samples also investigated. For optimized : sample, uniform nanorods sizing from 10 to 30 nm in diameter 200 300 length obtained strongest green color narrow bands under UV excitation (325 nm). results revealed that, after being...

Bài toán định tuyến vận tải di chuyển trong môi trường có đặc tính thay đổi linh hoạt đã được nghiên cứu nhiều năm. Việc xây dựng bài tìm đường đi tối ưu rất cần thiết thực tế. Đặc biệt, khi chi phí giao hàng xu hướng tăng ổn và thường ngang bằng với giá thành của hóa. Điểm nổi bật là thời gian thiểu coi tiêu chí chứ không phải khoảng cách như hầu hết các công trình trước đây. Chúng tôi sử dụng phương pháp quang học - hình đề xuất bởi tác giả A.L.Kazakov A.A.Lempert để phát triển ứng dụng,...
In this paper, the Gd2O3:Eu3+ nanospheres with ratio Eu3+/Gd3+ of 6% mol were successfully synthesized by a multi-step chemical method mean nanoparticles size about 200 to 220 nm and low standard deviation. The morphology, structure optical behavior as-synthesized annealed Gd2O3:6%Eu3+ samples investigated field-emission scanning electron microscopy (FESEM), X-ray diffractions (XRD), photoluminescence spectroscope (PL) luminescence lifetime was also discussed. biomedical nanocomplexes IgG...
We have successfully demonstrated a simple and low-cost fabrication technique, called direct laser writing (DLW), for realisation of photonic plasmonic nanostructures. First, based on low one-photon absorption (LOPA) phenomena in weakly absorbing photoresist (532 nm vs. SU8 or S18 photoresist), this DLW enabled production submicrometre 2D 3D structures demand using very modest power. also that the LOPA allowed embedding single nanoparticle (fluorescent, nonlinear, magnetic, metallic nature)...
The Fe3O4/Au/Eu(TTA)3 nanocomposite was functionalized with amino groups, which folic acid attached to the groups permit targeting of certain cancer cell lines that express high levels folate receptor. In this paper, a Fe3O4/Au/Eu(TTA)3-folate nanocomplex successfully synthesized. as-synthesized material has small size from 75 100 nm in diameter and good dispersity solution. addition, exhibits strong emission at λmax = 614 nm, superparamagnetic properties biocompatibility.
In recent years, solid waste pollution has been a burden on sustainable development in Vietnam. The suburban districts major cities, particular, have all witnessed high rate of urbanization and rapidly increasing amount waste. Focusing the case unsustainably managed Hoai Duc district (2016-2020), five research hypotheses, including factors affecting increase Duc, are proposed, i.e.: Industrialization (based change agricultural land area), population growth, (manifested by changes urban...
