Manganese phosphide MnP has been investigated for decades because of its rich magnetic phase diagram. It is well known that the MnP exhibits the ferromagnetic phase transition at T C = 292 K and the helical magnetic phase below T N = 47 K at zero field. Recently, a novel magnetic phase transition was observed at T* =…
The organic conducting PEDOT-PSS aerogels can be prepared by supercritical CO2 drying of metal ion crosslinked PEDOT-PSS supermolecular hydrogels. The PEDOT-PSS hydrogel precursors were synthesized by polymerizing 3,4-ethylenedioxythiophene with excess ferric nitrate as oxidizing agent as well as crosslinking agent in…

This feature article introduces a deterministic approach for the rapid, single-step, direct synthesis of metal oxide nanowires. This approach is based on the exposure of thin metal samples to reactive oxygen plasmas and does not require any intervening processing or external substrate heating. The critical roles of th…
We demonstrate a water-based etching strategy for converting solid silica shells into porous ones with controllable permeability. It overcomes the challenges of the alkaline-based surface-protected etching process that we previously developed for the production of porous and hollow silica nanostructures. Mild etching…
Cytocompatible, co-doped cerium oxide nanoparticles exhibited strong upconversion properties that were found to kill lung cancer cells by inducing apoptosis thereby demonstrating the potential to be used as clinical contrast agents for imaging and as therapeutic agents for treatment of cancer.
In the present study, the in vivo distribution of polyelectrolyte multilayer coated gold nanoparticles is shown, starting from the living animal down to cellular level. The coating was designed with functional moieties to serve as a potential nano drug for prion disease. With near infrared time-domain imaging we follo…
Stimuli-sensitive emulsions stabilized by microgel particles consisting of poly-(N-isopropylacrylamide-co-methacrylicacid) (PNIPAM-co-MAA) and being responsive to both pH and temperature have been investigated with respect to the visco-elastic properties of the interfacial layer. Properties of the interfacial layer we…
Over the last number of years several simulation methods have been introduced to study rare events such as nucleation. In this paper we examine the crystal nucleation rate of hard spheres using three such numerical techniques: molecular dynamics, forward flux sampling, and a Bennett–Chandlertype theory where the nucle…
This study presents a novel nanocomposite conducting plate (CP) reinforced by graphene at a low weight fraction percentage, and compares the properties of this novel nanocomposite CP with those containing various weight fractions of multi-wall carbon nanotubes (MWCNT) (0.2, 0.5, and 1 phr). Adding only 0.2 phr of grap…
Abstract Plasmonics has conventionally been in the realm of metal‐optics. However, conventional metals as plasmonic elements in the near‐infrared (NIR) and visible spectral ranges suffer from problems such as large losses and incompatibility with semiconductor technology. Replacing metals with semiconductors can allev…
A squirting capsule is designed to deliver nanoparticles inspired by the squirting cucumber ejecting its seeds. The capsule has a thermo-sensitive hydrogel shell, and encapsulates nanoparticles by emulsifying the nanoparticle aqueous suspension in the water-in-oil emulsion core. The squirting capsule can completely sq…
The development of hydrogen storage materials with high performance has been attracting considerable attention in recent years. Magnesium hydride, alanates, borohydrides and ammonia borane are the most promising candidates due to their high hydrogen capacity, but each type has its own shortcomings. In this short featu…
Wettability has been recognized as one of the most important properties of fibrous materials for both fundamental and practical applications. In this study, the plasma induced grafting of acrylic acid (AAc) was applied to improve the wettability of the electrospun poly(vinylidene fluoride) (PVDF) nanofiber membranes.…
Graphene has received great attention because of its exceptional properties and formidable potential in various applications. A practical approach to the production of processable graphene sheets in large quantities at low cost is the key to exploiting most proposed applications. Here we show a dehydration and stabili…
In this work, we have successfully developed a mild solution-based route to elaborate well-aligned MoO3 and MoO2 nanorods as the electrode active materials directly on metallic current collectors for the first time. Prior to nanostructure growth, an incubation layer, containing peroxomolybdate precursors is deposited…
BACKGROUND: Accumulating evidence indicate that the degree of dispersion of nanoparticles has a strong influence on their biological activities. The aims of this study were to develop a simple and rapid method of nanoparticle dispersion using a natural lung surfactant and to evaluate the effect of dispersion status of…
Electrostatic spinning (Electrospinning, ES) was applied to prepare Donepezil HCl loaded nanofibers as a potential orally dissolving dosage form. Electrospinning of water solutions of different polymers were performed in order to fabricate a consistent and removable web on the collector with ultra-fast dissolution in…
Colloidal semiconductor quantum rods have demonstrated many advantageous properties as light emitters such as high quantum yield, tunable emission wavelength, and polarized emission. This makes them an interesting optical gain material for laser applications. We report room-temperature gain lifetimes in core/shell CdS…
DFT calculations reveal that aminotriazines have a strong affinity for graphite and suggest that part of the driving force for adsorption is a specific attractive interaction of NR(2) groups with the underlying surface.
