Bi 2 Te 2.7 Se 0.3 (BTS) is known to be the unique n-type commercial thermoelectric (TE) alloy used at room temperatures, but its figure of merit ( ZT ) is relatively low, and it is vital to improve its ZT for its wide applications. Here, we show that incorporation of an appropriate amount of GaAs nanoparticles in BTS…
Cyclohexane-1,2,4,5-tetracarboxylic diimide with a nonconjugated core has been incorporated to bridge two conventional triphenylamine units. The obtained monomer has successfully hypsochromically shifted the maximum absorption wavelength by 10 nm in comparison to the one with a pyromellitic diimide bridge. Consequentl…
Compared with the crystalline transition metal oxyhydroxide, low-crystalline structure is conducive to high electrochemical performance due to its more grain boundaries and ion diffusion channels. However, the manufacture of low-crystalline oxyhydroxides remains challenging, especially those with multiple transition m…
A functional substrate with heterogeneous wettability elaborately integrates the water loving and repellent properties onto an individual surface. Compared with homogeneous surfaces, nonuniformity in wettability endows a heterogeneous surface with a more remarkable capability for manipulation of the solid–liquid–gas i…
The phytosynthesis of metal oxides nanoparticles (NPs) has been extensively reported; yet mechanism involved and incorporated bioactive compounds in the synthesized NPs are still need to be investigated. In this regard, here an efficient sustainable co-precipitation synthesis of zinc oxide nanoparticles (ZnO NPs) has…
It is attractive and encouraging to develop new fluorescent carbon dots (CDs) with excellent optical properties and promising applications prospects. Herein, highly-efficient green emissive CDs ( m -CDs) with a high quantum yield (QY) of 71.7% in water are prepared through a facile solvothermal method. Interestingly,…
Abstract Species-specific enzyme detection refers to an important modality in the field of monitoring foodborne pathogens. Particularly, β-galactosidase (β-gal) has been extensively employed for ascertaining the concentration of Escherichia coli (E. coli). The major challenges facing the recent works include improving…
Abstract Magneto‐optic effect is attracting wide interest as it renders a contactless, potentially power‐free, highly sensitive and spatio‐temporal resolved way in both magnetic material characterization and light manipulation. Intensive explorations exhibit its potential in diverse applications such as optical commun…
The corrosion behavior of Mg-Nd binary alloys in the harsh South China Sea environment was researched by scanning electron microscopy, energy-dispersive spectrometry and X-ray diffraction analysis. In order to explain the corrosion mechanism, corrosion resistance was analyzed by weight loss rate and electrochemical me…
Increasing demands in minimization of fire risks and meeting fire safety requirements by polymers require advances in knowledge of flame-retardant materials suitable for use in fire-retardancy applications. The present work represents the seminal review of alginate/polymer-based materials as flame retardants. Alginate…
Abstract Most syntheses of advanced materials require accurate control of the operating temperature. Plasmon resonances in metal nanoparticles generate nanoscale temperature gradients at their surface that can be exploited to control the growth of functional nanomaterials, including bimetallic and core@shell particles…
(e.g., 111-622-811). Despite the importance of these materials and tremendous progress with density functional theory (DFT) calculations in understanding basic design principles, it is computationally prohibitively expensive to make this problem tractable. Specifically, predicting the open circuit voltage for any cath…
This study presents the preparation of membranes of polylactic acid (PLLA), polyacrylonitrile (PAN) and their corresponding membranes coated with polyaniline (PANI) for the adsorption of methylene blue (MB). Scanning electron microscopy micrographs reveal that all the membranes exhibit nanofibrous morphology. The adso…
In the field of synthesis and processing of noble metal nanoparticles, the study of the bottom-up method, called Ultrasonic Spray Pyrolysis (USP), is becoming increasingly important. This review analyses briefly the features of USP, to underline the physical, chemical and technological characteristics for producing na…
The cellulose/graphene oxide (GO) networks as the scaffold of free-standing aerogel electrodes are developed by using lithium bromide aqueous solution, as the solvent, to ensure the complete dissolution of cotton linter pulp and well dispersion/reduction of GO nanosheets. Polyaniline (PANI) nanoclusters are then coate…

This new finding opens a window of opportunity for the rational designing of next-generation energy storage devices, supercapatteries, that combine the characteristics of batteries (high energy) and supercapacitors (high power).
In recent years, there has been an increasing interest in the study of lightweight syntactic foams (SFs) because of their tailorable properties, quality characteristics and suitable applications in diverse technology industry. A considerable amount of literature has been published on SFs with most of these studies foc…
ConspectusPlasmonic nanostructures have garnered widescale scientific interest because of their strong light-matter interactions and the tunability of their absorption across the solar spectrum.
