Integration of quasi-two-dimensional (2D) films of metal-chalcogenides in optical microcavities permits new photonic applications of these materials. Here we present tunable microcavities with monolayer MoS2 or few monolayer GaSe films. We observe significant modification of spectral and temporal properties of photolu…
The paper demonstrates a class of multifunctional core-shell hybrid nanogels with fluorescent and magnetic properties, which have been successfully developed for simultaneous optical temperature sensing, tumor cell imaging and magnetic/NIR-thermally responsive drug carriers. The as-synthesized hybrid nanogels were des…
The research of p-type dye-sensitized solar cells (p-DSSCs) has attracted growing attention because of the potential for integration with conventional n-type DSSCs (n-DSSCs) into the more efficient tandem-DSSCs. However, to date the performance of p-DSSCs is lagging behind that of n-DSSCs. One main reason is the lack…
A new form of nanoceria, porous nanorods of ceria (PN-CeO 2 ), was prepared by a two-step hydrothermal synthesis. PN-CeO 2 has been found to display enhanced reducibility and capacity for oxygen storage.
Sandwich-structured hierarchical (MnO 2 , PPy)/rGO nanosheets composites exhibited a maximum specific capacitance of 404 F g −1 and ∼91% of capacitance retention over 5000 cycling.
Reduced graphene oxide (rGO) sheet and ternary-component Ni(1-x)Co(x)Al-layered double hydroxide (Ni(1-x)Co(x)Al-LDH) hybrid composites with an interesting sandwich structure have been fabricated by an in situ growth route. The as-obtained composite displays a sandwich architecture constructed by the self-assembly of…
Silicene monolayers grown on Ag(111) surfaces demonstrate a band gap that is tunable by oxygen adatoms from semimetallic to semiconducting type. With the use of low-temperature scanning tunneling microscopy, we find that the adsorption configurations and amounts of oxygen adatoms on the silicene surface are critical f…
Selective detection of bioanalytes in physiological fluids, such as blood, sweat or saliva, by means of low-cost and non-invasive devices, is of crucial importance to improve diagnosis and prevention in healthcare. To be really useful in everyday life a sensing system needs to be handy, non-invasive, easy to read and…
Sodium metal phosphates, NaMPO 4 (M = Mn, Co and Ni) were successfully synthesized by a solution combustion synthesis (SCS) method using glycine-nitrate as a precursor.
The TEM image of the synthesized iron oxide nanocrystals.
Natural halloysite nanotubes (HNTs) modified with 3-aminopropyltriethoxysilane were used as an aspirin carrier.
We have investigated the crystal field splitting in the archetypal lanthanide-based single-ion magnets and related complexes (NBu4)+[LnPc2]−·2dmf (Ln = Dy, Ho, Er; dmf = N,N-dimethylformamide) by means of far infrared and inelastic neutron scattering spectroscopies. In each case, we have found several features corresp…
At present, safety evaluation standards for nanofood additives are made based on the toxic effects of a single additive. Since the size, surface properties and chemical nature influence the toxicity of nanomaterials, the toxicity may have dramatically changed when nanomaterials are used as food additives in a complex…
Magnesium nanoparticles have been synthesized by reducing di-n-butylmagnesium with lithium in the presence of naphthalene as an electron carrier. The reactants' ratio significantly influenced the particle size leading to some control of the nucleation and growth process with magnesium particles as small as 8 nm produc…
Two phosphoniobate-based 3D frameworks were firstly constructed using the hexa-capped Keggin polyoxoniobates [PNb12O40(VO)6](3-) and copper cations. Photocatalytic studies indicated that the hybrid materials exhibit photocatalytic hydrogen evolution activity.
NCC-attached dual-sensitive copolymers of N -isopropylacrylamide and acrylic acid (AA) with different contents of AA were synthesized by RAFT polymerization. Effect of NCC, AA content, and pH on LCST was evaluated.
There is a need to develop a simple, cheap, and accessible method of treating patients with kidney failure, especially in resource-limited environments such as disaster areas and the developing world due to the inaccessibility of conventional hemodialysis treatments. In this study, we develop a zeolite-polymer composi…
This critical review presents the sources and sinks of nanoceria in the environment, detection and characterization methods, fate and transport processes, toxicity and likelihood of toxicity in soil and water.
Halogenated graphene derivatives are interesting for their outstanding physical and chemical properties. In this paper, we present various methods for the synthesis of brominated graphene derivatives by the bromination of graphite oxides. Graphite oxides, prepared according to either the Hummers or Hofmann method, wer…
In this study we have investigated the suitability of a number of different mesoporous silica nanoparticle structures for carrying a drug cargo. We have fully characterized the nanoparticles in terms of their physical parameters; size, surface area, internal pore size and structure. These data are all required if we a…
