Magnetic nanoparticles and magnetic particle spectroscopy-based bioassays: a 15 year recap Nano Futures (IF 2.1) Pub Date : 2022-04-07 Kai Wu, Jinming Liu, Vinit Kumar Chugh, Shuang Liang, Renata Saha, Venkatramana D Krishna, Maxim C-J Cheeran, Jian-Ping Wang
Magnetic nanoparticles (MNPs) have unique physical and chemical properties, such as high surface area to volume ratio and size-related magnetism, which are completely different from their bulk materials. Benefiting from the facile synthesis and chemical modification strategies, MNPs have been widely studied for applications in nanomedicine. Herein, we firstly summarized the designs of MNPs from the

Multi-orbital topolectrical circuit for topological quantum states Nano Futures (IF 2.1) Pub Date : 2022-04-06 Junjie Yao, Xiamin Hao, Biyu Song, Yizhen Jia, Chenqiang Hua, Miao Zhou
Remarkable progress has been made in using electric circuits as a powerful platform to realize a plethora of exotic topological quantum states, even of higher orders and/or dimensions. So far the proposed circuits are restricted to a single-orbital tight-binding model with different lattices. Here, we introduce the concept of a multi-orbital topolectrical circuit and construct practical LC circuits

One-pot synthesis of 1T MoS2/MWCNT hybrids for enhanced zinc-ion storage Nano Futures (IF 2.1) Pub Date : 2022-04-05 Yu-Ting Wang, Ze-Zhi Zhang, Ming-Xue Li
Two-dimensional transition metal dichalcogenides are regarded as the ideal hosts for zinc-ions. Herein, a facile hydrothermal method is proposed to fabricate the metallic phase (1T phase) MoS2/multi-walled carbon nanotube (MWCNT) hybrids serving as the cathode materials for zinc-ion batteries (ZIBs). By virtue of the exertion of phase engineering and the synergy between the 1T MoS2 nanosheets and MWCNT

Moiré patterns and carbon nanotube sorting Nano Futures (IF 2.1) Pub Date : 2022-02-28 Olga V Konevtsova, Daria S Roshal, Sergei B Rochal
Moiré patterns (MPs), arising from the superposition of two lattices with close periods, are tightly related to the physicochemical properties of bilayer nanostructures. Here, we develop the theory of complex MPs emerging in twisted bilayer graphene and planar nets of double-walled nanotubes at significant relative twist and/or deformation of layers. The proposed theory clarifies the physicochemical

Raman spectroscopy of colloidal semiconductor nanocrystals Nano Futures (IF 2.1) Pub Date : 2022-02-25 Klaus Boldt
Raman spectroscopy is a powerful method that gives insight into the atomic structure and composition of nanomaterials, but also allows to draw conclusions about their electronic properties. It is based on the inelastic scattering of light, which is able to excite phonons in the material. In the field of semiconductor nanocrystals, Raman spectroscopy has been employed to make significant contributions

Novel ternary metal oxide nanoparticles (La2Cu0.8Zn0.2O4) as a potential photocatalyst for visible light photocatalytic degradation of methylene blue and desulfurization of dibenzothiophene Nano Futures (IF 2.1) Pub Date : 2022-02-24 Molood Barmala, Mohammad Behnood
In this work we present the preparation of novel ternary metal oxide nanoparticles, La2Cu0.8Zn0.2O4 (LCZO), using a simple co-precipitation method. The crystalline structure, morphology and composition of the prepared LCZO nanoparticles were characterized by x-ray diffraction, scanning electron microscopy and energy-dispersive x-ray analysis. The diffuse reflectance spectrum investigation showed that

An investigation into the environmental and therapeutic applications of holmium-doped titanium dioxide (Ho-TiO2) nanocatalysts: a kinetic and thermodynamic study of the photocatalytic degradation of Safranin O dye Nano Futures (IF 2.1) Pub Date : 2022-02-07 F Akbar Jan, Wajidullah1, Rahat Ullah, Salman2, Naimat Ullah, Abdul Salam
Titanium dioxide (TiO2) and holmium-doped titanium dioxide (Ho-TiO2) nanoparticles(NPs) were synthesized through a sol gel route. The synthesized NPs were characterized by ultraviolet-visible (UV–Vis) spectroscopy, x-ray diffraction (XRD), energy dispersive x-ray analysis, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy, and photoluminescence (PL) spectroscopy.
