For its powerful antimicrobial properties, nanosilver is the most widely used nanoparticle in commercial odor-neutralizing and anti-infective textiles. However, the recent prevalent use of nanosilver has prompted concerns for the potential adverse human and environmental effects caused from the leaching of nanosilver during usage and laundering, ne...

Efficient hole-electron pair separation plays a crucial role in enhancing photocatalytic activity of g-C3N4, which usually requires a noble metal cocatalyst. Here we report metallic NiCo2S4 nanoparticles as a cocatalyst and replacement of noble metals to improve the performance of g-C3N4 for photocatalytic hydrogen evolution. NiCo2S4 nanoparticle-m...

In this contribution, comparison of TiO2 nanowires (TiO2 NWs) and TiO2 nanoparticles (TiO2 NPs) for photodegradation of resorcinol as endocrine model was extensively carried out. The results indicated that X-ray diffraction (XRD) patterns of the TiO2 NWs exhibited brookite and anatase phases; whereas, the prepared TiO2 NPs is pure anatase phase. TE...

The one-dimensional (1D) silver nanowires (AgNWs) with high transmittance, high electronic conductivity and two-dimensional (2D) reduced graphene oxide (rGO) both emerge as leading candidates for the development of next-generation transparent conductive films (TCFs). However, the relatively high sheet resistance of rGO and the poor corrosion resist...

Based on the density functional theory (DFT) method, the geometrical structures, relative stability, electronic, and spectral properties of AuSn (2 ≤ n ≤ 7) clusters are systematically studied, whose sizes are largely in the range of 0.3–0.5 nm. AuS4 and AuS3 show the highest and lowest energy gaps and hence the highest chemical stability and chemi...

In this work, we designed a simple hydrothermal synthetic method for a [email protected]α-Co(OH)2 [email protected] material with good electrochemical properties. The obtained material had a specific capacitance of 423.92 F g−1 at 1 A g−1 and a cycling retention ratio of 78.48% after 1000 cycles at 5 A g−1. A hybrid supercapacitor device ([email protected]α-Co(...

A comprehensive study of the antibacterial (bacteriostatic and bactericidal) properties of non-doped carbon nanodots (CNDs), nitrogen-doped (N-doped), and nitrogen/sulfur co-doped (N,S-doped) CNDs against Escherichia coli (a model organism) is discussed herein. The CNDs, with a size of ca. 5 nm, were found to be capable of inhibiting the growth of ...

The study of bimetallic nanoalloy clusters is of considerable interest due to its interesting electronic, optical, magnetic and catalytic properties. The geometrical structure and electronic properties of AunPt (n = 1–8) nanoalloy clusters are studied by using the density functional theory methodology. The result exhibits that the ground-state conf...

Over the past few decades, detonation nanodiamonds (NDs) have gained increased attention due to their unique physicochemical properties. Various methods for preparation of ND suspensions have been introduced. This paper presents thermally annealed nanodiamonds dispersed via sonication and separated by centrifugation in deionized water and dimethylf...

The presented analysis of the temperature course of a phase transformation of nanoparticles offers a powerful tool to obtain data for the particle size distribution and the enthalpy of transformation. The analysis starts with the temperature distribution within an ensemble of nanoparticles and a functional relation between particle size and transfo...
