The efficient storage of hydrogen is one of three major hurdles towards a potential hydrogen economy. This report begins with conventional storage methods for hydrogen and broadly covers new technology, ranging from physical media involving solid adsorbents, to chemical materials including metal hydrides, ammonia bora…
Nitrogen-doped carbon dots (CDs) have attracted great interest due to their extraordinary properties, especially their enhanced emission efficiency, and thus a facile synthesis of nitrogen-doped CDs with high emission efficiency is critical for practical applications. To improve the emission efficiency of CDs, herein…
The unique plasma-specific features and physical phenomena in the organization of nanoscale soild-state systems in a broad range of elemental composition, structure, and dimensionality are critically reviewed. These effects lead to the possibility to localize and control energy and matter at nanoscales and to produce…
A facile approach for extracting cellulose nanocrystals (CNCs) was presented through hydrochloric acid hydrolysis of cellulose raw materials under hydrothermal conditions. The influences of preparation parameters, such as reaction time, reaction temperature, and acid-to-cellulose raw material ratio, and different neut…
As one of the most common chemical materials, titanium dioxide (TiO2) has been prepared and widely used for many years. Among all the applications, the biomedical applications of TiO2 have motivated strong interest and intensive experimental and theoretical studies, owing to its unique photocatalytic properties, excel…
Hydrogels can be formed by the self-assembly of certain small molecules in water. Self-assembly occurs via non-covalent interactions. The self-assembly leads to the formation of fibrous structures which form the matrix of the gel. The mechanical properties of the gels arise from the properties of the fibres themselves…
We designed and synthesized a perfluorinated covalent triazine-based framework (FCTF-1) for selective CO2 capture. The incorporation of fluorine (F) groups played multiple roles in improving the framework's CO2 adsorption and separation capabilities. Thermodynamically, the strongly polar C–F bonds promoted CO2 adsorpt…
Highly fluorescent graphitic carbon nitride quantum dots (g-CNQDs) with a quantum yield of 42% are synthesized by a low-temperature solid-phase method with urea and sodium citrate as the precursors. Notably, the tunable emission of g-CNQDs can be achieved by simply adjusting the molar ratio of the two reactants.
Dynamic light scattering is a method that depends on the interaction of light with particles. This method can be used for measurements of narrow particle size distributions especially in the range of 2–500 nm. Sample polydispersity can distort the results, and we could not see the real populations of particles because…
Antimicrobial materials with immobilized/entrapped silver nanoparticles (AgNPs) are of considerable interest. There is significant debate on the mode of bactericidal action of AgNPs, and both contact killing and/or ion mediated killing have been proposed. In this study, AgNPs were immobilized on an amine-functionalize…
A reversible single-crystal-to-single-crystal transformation is used to dramatically change the relaxation behavior of a single-ion magnet. The coordination geometry of the DyIII site of a [Zn–Dy–Zn] complex changes from pentagonal–bipyramid (quasi-D5h) to octahedron (quasi-Oh), inducing an energy barrier change from…
To meet the pressing demands for portable and flexible equipment in contemporary society, it is strongly required to develop next-generation inexpensive, flexible, lightweight, and sustainable supercapacitor systems with large power densities, long cycle life, and good operational safety. Here, we fabricate a flexible…
Starch ampholytes (AmS) – cationic starch succinates – with the degree of substitution according tocationic groups of 0.29 or 0.36 and the degree of substitution according to anionic groups from 0.11 to0.34 were prepared by succinylation of precationized starch. FT-IR spectra confirmed the incorporationof carboxylic gr…
The development of high-performance shielding materials against electromagnetic pollution requires mobile charge carriers and magnetic dipoles. Herein, we meet the challenge by building a three-dimensional (3D) nanostructure consisting of chemically modified graphene/Fe3O4(GF) incorporated polyaniline. Intercalated GF…
An asymmetric supercapacitor (ASC) is a supercapacitor based on two different electrode materials. One electrode is based on redox (Faradic) reactions with or without non-faradic reactions, and the other one is mostly based on electric double-layer (non-Faradic or electrostatic) absorption/desportion. Aqueous electrol…
Graphene, a two-dimensional carbon sheet with one atom thickness and one of the thinnest materials in universe, has inspired huge interest in physics, materials science, chemistry and biology. However, pure graphene sheets are limited for many applications despite their excellent characteristics and scientists face ch…
Graphene has attracted extensive interest in the field of supercapacitor research due to its 2D structure which grants it exceptional properties such as superior electrical conductivity and mechanical properties as well as an extensive surface area better than that of carbon nanotubes (CNTs). Furthermore, unlike other…

Because of their unique chemical and physical properties, inorganic semiconducting nanostructures have gradually played a pivotal role in a variety of research fields, including electronics, chemical reactivity, energy conversion, and optics. A major feature of these nanostructures is the quantum confinement effect, w…
The field of energy textiles is growing but continues to face two main challenges: (1) flexible energy storage does not yet exist in a form that is directly comparable with everyday fabrics including their feel, drape and thickness, and (2) in order to produce an “energy textile” as part of a garment, it must be fabri…
