In this study we employed self-deposition and competitive or synergistic interactions between metal ions and gold nanoparticles (Au NPs) to develop OR, AND, INHIBIT, and XOR logic gates through regulation of the enzyme-like activity of Au NPs. In the presence of various metal ions (Ag(+), Bi(3+), Pb(2+), Pt(4+), and H…
Sr2Fe1.5−xNixMo0.5O6−δ (x = 0, 0.05, 0.1, 0.2, 0.4) (SFNM) materials have been synthesized by a sol–gel combustion method and studied towards application as cathode materials for intermediate temperature solid oxide fuel cells (IT-SOFCs). The crystal structure, microstructure, thermal expansion, element valence, condu…
A facile and general method to covalently functionalize graphene oxide (GO) with copolymers, using poly(styrene-co-methylmethacrylate) (P(St-co-MMA)) as an example, via miniemulsion polymerization is described in this study. After in situ reduction, insulating GO is converted to conductive reduced-graphene oxide (RGO)…
Hexagonal corundum-type indium oxide (h-In2O3) is the structure that normally exists in a high-temperature and pressure environment. This structure has been realised from ambient environment stable cubic indium oxide (c-In2O3) using a high-energy ball milling approach at room temperature, in which the rearrangements o…
Supported gold nanoparticles have recently been shown to possess intriguing catalytic activity for hydrogenation reactions, particularly for selective hydrogenation reactions. However, fundamental studies that can provide insight into the reaction mechanisms responsible for this activity have been largely lacking. In…
The influence of nucleating agents (nano-sized calcium carbonate and sodium benzoate) on mechanical and thermal properties of PLA/PBS co-continuous blends was investigated. PLA/PBS 60/40, 50/50, 40/60 wt% blends were compounded with NPCC or SB (0.5 and 1.0 phr) in a twin-screw extruder and fabricated into thin sheets…
The temperature prevailing in the catalyst bed of three different IR spectroscopic reaction cells was assessed by means of thermocouples, an optical pyrometer and reaction rate measurements. One of the cells was a custom-made transmission FT-IR cell for use with thin wafers and the two others were commercial Harrick a…
Montmorillonite/poly(vinyl alcohol) (MMT/PVA) nanocomposites spanning the complete range of MMT content (0-100 wt%) are prepared by simple evaporation-induced assembly. Effects of MMT content on the structure and mechanical properties of nanocomposites are systematically investigated and exhibit two important transiti…
The potential use of methanol as a fuel is well known. Many research scientists are working on single stage production of methanol. Currently it is being produced by a conventional two-step process which is expensive and energy intensive. Conversion of methane to a liquid fuel is a more desirable alternative to compre…
CoNi alloy nanoparticles anchored on a spherical carbon monolith (CoNi-C) were prepared by a solvothermal route and subsequent heat treatment without any templates. Their permittivity and permeability behaviors were studied in the frequency range of 2-18 GHz. The CoNi-C composites showed the best microwave absorbing p…
Chitosan is a naturally occurring biopolymer having diversified applications not only in the pharmaceutical field, but also in the biomedical profession. The presence of functional groups, i.e., hydroxyl, acetamido, and amine in the chitosan parent backbone, makes it a suitable candidate for chemical modification, and…
Developing flexible and deformable supercapacitor electrodes based on porous materials is of high interest in energy related fields. Here, we show that carbon nanotube sponges, consisting of highly porous conductive networks, can serve as compressible and deformation-tolerant supercapacitor electrodes in aqueous or or…
In this tutorial review the preparation of monolithic silica materials with hierarchical porosity by the competing processes of sol-gel transition and chemical phase separation is summarized. Four principally different routes will be discussed in detail, including multiple micellar as well as high internal phase emuls…
We have presented a self-cross-link strategy to fabricate HSA nanoparticles using a desolvation method. The nanoparticles were stabilized by intermolecular disulfide bonds while still dissolvable in reducing media. The fabrication process does not involve any toxic chemicals and hence the nanoparticles may be useful a…
The repeatable wettability of the facile-to-fabricate porous copper surface shows superhydrophobicity in air and improved superhydrophobicity under oil. The resultant 3D copper foam can separate and capture oils from water with high separation efficiency, fast capture kinetics, fine mechanical resistance to water impa…
Herein, we report on how to teach a thermoplastic polyurethane elastomer completely stress-free, bidirectional motion. Briefly spoken, we applied training, consisting of extensive tensile deformation in the specimen's viscoelastic state, initiating deformation-induced crystallization. Once unloaded, thermo-reversible…
A novel photochromic diarylethene with a salicylidene Schiff base substituent has been synthesized and characterized. The diarylethene could be used as a multi-addressable fluorescence switch when triggered by light, protons and metal ions. As a result, two logic circuits were constructed with the unimolecular platfor…
This study analyses and compares the behaviour of 5 commercial porous carbons in the ionic liquid N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (PYR14TFSI) and its mixture with propylene carbonate (PC) as electrolytes. The results of this investigation show that the existence of a distribution of po…
We propose a new mechanism for destabilizing Mg-H bonding by means of a combination of the size effect and MgH2-carbon scaffold interfacial bonding, and experimentally realize low temperature hydrogen release starting from 50 °C using an MgH2@CMK-3 nanoconfinement system (37.5 wt% MgH2 loading amount). Based on comput…
Harnessing the properties of biomolecules, such as peptides, adsorbed on inorganic surfaces is of interest to many cross-disciplinary areas of science, ranging from biomineralisation to nanomedicine. Key to advancing research in this area is determination of the peptide conformation(s) in its adsorbed state, at the aq…
