Peisan Wang, Chunxia Qi, Pengchao Wen, Luyuan Hao, Xin Xu, Simeon Agathopoulos
Τhe photocatalytic activity in the range of visible light wavelengths and the thermal stability of the structure were significantly enhanced in Si, N co-doped nano-sized TiO2, and synthesized through high-energy mechanical milling of TiO2 and SiO2 powders, which was followed by calcination at 600 °C in an ammonia atmosphere. High-energy mechanical milling had a pronounced effect on the mix...... hiện toàn bộ
Fundamentals to Apply Magnetic Nanoparticles for Hyperthermia TherapyNanomaterials - Tập 11 Số 5 - Trang 1203
Hira Fatima, Tawatchai Charinpanitkul, Kyo‐Seon Kim
The activation of magnetic nanoparticles in hyperthermia treatment by an external alternating magnetic field is a promising technique for targeted cancer therapy. The external alternating magnetic field generates heat in the tumor area, which is utilized to kill cancerous cells. Depending on the tumor type and site to be targeted, various types of magnetic nanoparticles, with variable coat...... hiện toàn bộ
Hierarchical Doped Gelatin-Derived Carbon Aerogels: Three Levels of Porosity for Advanced SupercapacitorsNanomaterials - Tập 10 Số 6 - Trang 1178
Ayshuwarya Kandasamy, Tamilselvi Ramasamy, Ayesha Samrin., N. Padmanathan, M. Ramesh, Olha Bazaka, Igor Levchenko, Kateryna Bazaka, M. Mandhakini
Nitrogen-doped graphene-based aerogels with three levels of hierarchically organized pores were prepared via a simple environmentally friendly process, and successfully tested in supercapacitor applications. Mesopores and macropores were formed during the aerogel preparation followed by carbonization and its chemical activation by potassium hydroxide (KOH). These mesopores and macropores c...... hiện toàn bộ
Efficient Photoelectrochemical Water Splitting by Tailoring MoS2/CoTe Heterojunction in a Photoelectrochemical CellNanomaterials - Tập 10 Số 12 - Trang 2341

Solar energy conversion through photoelectrochemical water splitting (PEC) is an upcoming promising technique. MoS2/CoTe heterostructures were successfully prepared and utilized for PEC studies. MoS2 and CoTe were prepared by a hydrothermal method which were then ultrasonicated with wt. % ratios of 1:3, 1:1 and 3:1 to prepare MoS2/CoTe (1:3), MoS2/CoTe (1:1) and MoS2/CoTe (3:1) heterostruc...... hiện toàn bộ
Low-Power Graphene/ZnO Schottky UV Photodiodes with Enhanced Lateral Schottky Barrier HomogeneityNanomaterials - Tập 9 Số 5 - Trang 799
Youngmin Lee, Deuk Young Kim, Sejoon Lee
The low-power, high-performance graphene/ZnO Schottky photodiodes were demonstrated through the direct sputter-growth of ZnO onto the thermally-cleaned graphene/SiO2/Si substrate at room temperature. Prior to the growth of ZnO, a thermal treatment of the graphene surface was performed at 280 °C for 10 min in a vacuum to desorb chemical residues that may serve as trap sites at the interface...... hiện toàn bộ
Polypropylene Nanocomposite Filled with Spinel Ferrite NiFe2O4 Nanoparticles and In-Situ Thermally-Reduced Graphene Oxide for Electromagnetic Interference Shielding ApplicationNanomaterials - Tập 9 Số 4 - Trang 621

Herein, we presented electromagnetic interference shielding characteristics of NiFe2O4 nanoparticles—in-situ thermally-reduced graphene oxide (RGO)—polypropylene nanocomposites with the variation of reduced graphene oxide content. The structural, morphological, magnetic, and electromagnetic parameters and mechanical characteristics of fabricated nanocomposites were investigated and studied...... hiện toàn bộ
In-Out Surface Modification of Halloysite Nanotubes (HNTs) for Excellent Cure of Epoxy: Chemistry and Kinetics ModelingNanomaterials - Tập 11 Số 11 - Trang 3078

In-out surface modification of halloysite nanotubes (HNTs) has been successfully performed by taking advantage of 8-hydroxyquinolines in the lumen of HNTs and precisely synthesized aniline oligomers (AO) of different lengths (tri- and pentamer) anchored on the external surface of the HNTs. Several analyses, including FTIR, H-NMR, TGA, UV-visible spectroscopy, and SEM, were used to establis...... hiện toàn bộ
