In this article, we demonstrate the application of digital image correlation (DIC) in evaluating the strains and Poisson ratio of a range of soft materials in terms of their spatial and temporal resolutions. Homogeneous samples of polydimethylsiloxane (PDMS) elastomer were used as control substance and were measured t…
Highly dispersed metal nanoparticles were immobilized in the pores of a metal-organic framework (MOF), MIL-101, using a double solvents method. The resulting composites were investigated in the reduction of Cr(VI) to Cr(III) using formic acid, showing that the Pt and Pd catalysts were active with the Pt nanoparticles…
A combined ultrasound-vapour phase diffusion technique was used for the rapid synthesis of a terbium-based metal–organic framework (MOF), [Tb(1,3,5-BTC)]n. Compared with conventional solvothermal and ultrasound-assisted methods, such a kind of combined ultrasound-vapour phase diffusion technique is highly sufficient f…
Highly mesoporous carbon foam (MCF) with a high specific surface area has been successfully synthesized via a facile, cost-effective and template-free Pechini method. The as-prepared MCF exhibits a high specific surface area of 1478.55 m2 g−1 and a commendable pore size distribution for impregnating sulfur. After sulf…
Two classical metal clusters, CuI4I4 and CuI6S6, are introduced as functional connecting nodes to construct a novel multi-metal-cluster MOF [(CuI4I4)3(CuI6)2(3-ptt)12]n·24nDEF·12nH2O (1) that incorporate their inherent luminescent properties, induced by their respective metal–metal interactions. These two distinct clu…
A series of sulfonic acid-functionalized carbon materials (C–SO3H), including poly(p-styrenesulfonic acid)-grafted carbon nanotubes (CNT-PSSA), poly(p-styrenesulfonic acid)-grafted carbon nanofibers (CNF-PSSA), benzenesulfonic acid-grafted CMK-5 (CMK-5-BSA), and benzenesulfonic acid-grafted carbon nanotubes (CNT-BSA),…
A series of metal–organic frameworks (NOTT-100a (MOF-505a), NOTT-101a, NOTT-102a, NOTT-103a and NOTT-109a) with variable open copper sites and micropore spaces have been examined as potential adsorbents for methane storage. They exhibit high adsorption capacities for methane at 300 K and 35 bar (181–196 cm3 (STP) cm−3…
In this work, we describe the use of unfolded graphene as a three dimensional (3D) conducting network for LiFePO4 nanoparticle growth. Compared with stacked graphene, which has a wrinkled structure, the use of unfolded graphene enables better dispersion of LiFePO4 and restricts the LiFePO4 particle size at the nanosca…
Three perfluorinated Cu-based metal-organic frameworks (MOFs) were prepared starting from extensively fluorinated biphenyl-based ligands accessed via C-H functionalization. These new materials are highly hydrophobic: with water contact angles of up to 151 ± 1°, they are among the most water-repellent MOFs ever reporte…
Superparamagnetic iron oxide nanoparticles (SPIONs) have shown great promise in biomedical applications. In this review, we summarize the recent advances in the design and fabrication of core-shell and hetero-structured SPIONs and further outline some exciting developments and progresses of these multifunctional SPION…
An isoreticular series of cobalt-adeninate bio-MOFs (bio-MOFs-11–14) is reported. The pores of bio-MOFs-11–14 are decorated with acetate, propionate, butyrate, and valerate, respectively. The nitrogen (N2) and carbon dioxide (CO2) adsorption properties of these materials are studied and compared. The isosteric heats o…
A new AgNW-graphene hybrid transparent conducting electrode (TCE) was prepared by dry-transferring a chemical vapor deposition (CVD)-grown monolayer graphene onto a pristine AgNW TCE. The AgNW-graphene hybrid TCE exhibited excellent optical and electrical properties as well as mechanical flexibility. The AgNW-graphene…
Over the past decade extensive studies of single semiconductor nanowire and nanowire array photovoltaic devices have explored the potential of these materials as platforms for a new generation of efficient and cost-effective solar cells. This feature review discusses strategies for implementation of semiconductor nano…
Poly(N-vinylcarbazole) (PVK) was blended with graphene oxide (GO) to form a PVK–GO polymer nanocomposite capable of adsorbing heavy metal from aqueous solutions. The homogenous distribution of GO in the PVK–GO nanocomposite was determined by X-ray photoelectron microscopy (XPS) and attenuated total reflectance – infra…
Topological insulators represent unique phases of matter with insulating bulk and conducting edge or surface states, immune to small perturbations such as backscattering due to disorder. This stems from their peculiar band structure, which provides topological protections. While conventional tools (pressure, doping et…
The ability of Date palm Leaves powder (DPLP) to remove methylene blue (MB) from aqueous solutions by the biosorption process has been studied. Biosorption studies were carried out at different initial dye concentration, contact time, initial solution pH, biosorbent dosage, the particle size of (DPLP) and temperature.…
Here we report a rapid and simple microwave-assisted seeding technique for the synthesis of high-quality ZIF-8 membranes with an average propylene-propane selectivity of about 40. The new seeding method was found to be applicable to other ZIFs including ZIF-7 and SIM-1.
‘Structural electrolytes’ retain the desirable mechanical characteristics of structural (epoxy) resins whilst introducing sufficient ionic conductivity to operate as electrolytes in electrochemical devices. Here, a series of ionic liquid–epoxy resin composites were prepared to identify the optimum system microstructur…
It is known that low-dimensional carbon allotropes can be used as a new class of anode materials for lithium-ion batteries. However, the existing carbon allotropes cannot meet the increasing energy and power demand, and thus there is still a need for further development of new materials for lithium-ion batteries. In t…
Efficient hydrogen production and photocatalytic reduction of nitrobenzene were achieved by using a Pt-deposited amino-functionalised Ti(IV) metal–organic framework (Pt/Ti-MOF-NH2) under visible-light irradiation. XRD and N2 adsorption measurements revealed that crystalline microporous structures were formed and maint…
