Thickness-controlled uniform MoS <sub>2</sub> films are grown by polymer-assisted deposition approach from 50 nm to 2.5 nm, corresponding to bandgaps modulated from 1.50 eV to 1.64 eV. The photoresponse test demonstrates as-grown MoS <sub>2</sub> has fast response to light.
A superhydrophobic flexible tilt angle controlled needle surface is fabricated by integrating the methods of soft-lithography and crystal growth.
It can be difficult to reduce the electrical resistivity of highly degenerate semiconductors due to their high carrier concentration, impeding the further increase in their thermoelectric power factor.
In this study, we have developed an efficient and scalable method for improving the mechanical properties of carbon nanotube (CNT) fibers. The mechanical properties of as-synthesized CNT fibers are primarily limited by their porous structures and the weak bonding between adjacent CNTs. These result in inefficient load…
A direct “green” aqueous synthesis of mercapto acetate-stabilized copper indium sulfide (CIS) nanoparticles (NPs) and core/shell CIS@ZnS NPs of a varied composition under ambient conditions and a temperature lower than 100 °C is reported.
The elastic properties of the nanotubes of self-assembled aromatic dipeptide diphenylalanine are investigated by means of Raman spectroscopy and a mass-in-mass 1D model. Analysis of nanotubes' lattice vibrations reveals the essential contribution of the water in the nanochannel core of the tubes to the Young's modulus…
The adsorption properties of six NH <sub>3</sub> -SCR related small gases and the competitive adsorption of NH <sub>3</sub> , SO <sub>2</sub> and NH <sub>3</sub> , H <sub>2</sub> O were investigated.
The thermal conductivities of two groups of silicon nanoribbons of ∼20 and ∼30 nm thickness and various widths have been measured and analyzed through combining the Callaway model and the Fuchs-Sondheimer (FS) reduction function. The results show that while the data for the ∼30 nm thick ribbons can be well-explained b…
A number of plasmonic devices and applications, such as chemical and biological sensors, plasmon-enhanced solar cells, optical nanoantennas, metamaterials and metasurfaces, require the deposition of plasmonic metal nanocrystals on various substrates. Because the localized plasmon resonance modes, energies and strength…
The synergetic effect between Sb and Ce not only increases the surface acidity of the catalyst but also enhances the redox property, both of which contribute to improving NH <sub>3</sub> -SCR activity.
Electrospun niobium carbide/carbon nanofibers are a facile precursor to derive highly nanoporous carbide-derived carbon for supercapacitor applications, or niobium pentoxide/carbon for battery electrodes.
] (R = ethyl (1), n-propyl (2), n-butyl (3), n-hexyl (4) or n-octyl (5)) have been prepared and explored as single source precursors for use in melt reactions to form lead sulfide. X-ray single crystal structures of (2), (3) and (4) were used along with previously reported structures to investigate the influence of st…
Excitons play a key role in technological applications since they have a strong influence on determining the efficiency of photovoltaic devices. Recently, it has been shown that the allotropes of phosphorus possess an optical band gap that can be tuned over a wide range of values including the near-infrared and visibl…
This review article gives insights into the recent developments in the synthesis, functionalization, and potential applications of nanosized inorganic porous materials.
Nowadays, only by balancing the relationship of electromagnetic applications and electromagnetic pollution management can human health and quality of life be guaranteed.
In the present study pure, citric acid (CA) and l -valine (LV) doped potassium dihydrogen phosphate (KDP) crystals have been grown with the aim to investigate the nonlinear optical applications facilitated by UV–visible, third order nonlinear optical (TONLO) and dielectric properties. The structural parameters of grow…
We interpreted the mechanisms of energy harvesting and conversion for intrinsic upconverted mechano-persistent luminescence in CaZnOS through a native point defects study. We found that vacancy defects such as Zn and O vacancies, as well as Schottky pair defects, act as energy harvesting centers; they are very readily…

A three-dimensionally stretchable supercapacitor without an elastic substrate is created by designing a pyramid structure. Its specific capacitances are varied below 7% after stretching for thousands of cycles in three dimensions, and it exhibits the highest power and energy densities among the currently available str…
This paper reported that the peroxidase-like activity of DNA–Ag/Pt nanoclusters (NCs) can be inhibited selectively by Hg <sup>2+</sup> .
