The design and synthesis of novel examples of multifunctional magnetic materials based on the so-called coordination polymers (CPs) have become very attractive for chemists and physicists due to their potential applications in nanoscience and nanotechnology. However, their preparation is still an experimental challeng…
The encapsulation of metal clusters in endohedral metallofullerenes (EMFs) takes place in cages that in most cases are far from being the most stable isomer in the corresponding hollow fullerenes. There exist several possible explanations for the choice of the hosting cages in EMFs, although the final reasons are actu…
Metal-organic frameworks (MOFs) have been envisioned as alternatives to planar metallic catalysts for solar-to-fuel conversion. This is a direct result of their porous structure and the ability to tailor their optical absorption properties. This study investigates the band gap modulation of Zr-UiO-66 MOFs from both th…
Photocatalytic water oxidation is both phase and surface structure-sensitive due to the heat-driven first-step of O–H bond breaking.
The usage of high performance polymeric composites is a valuable alternative to conventional materials due to their high mechanical properties, stiffness to weight ratio and damage tolerance. The Mechanical property of epoxy matrices can be influenced by modifying the molecular architecture and structure, thereby incr…
Surface-assisted cyclotrimerization of arylalkynes was studied on Au(111) by means of scanning tunneling microscopy (STM) under ultra-high vacuum (UHV) conditions. Upon thermal activation, cyclotrimerization of 1,3,5-tris-(4-ethynylphenyl)benzene proceeds readily and with high selectivity, and results in two-dimension…
Polar polyimides with added CN dipoles exhibit higher discharged energy density than nonpolar polyimides such as Ultem and Kapton.
A carbon nanotube (CNT) network and molybdenum disulfide (MoS2) are rationally architected into a novel type of anode material in lithium ion batteries (LIBs), without the necessity for any binders. Enhanced structural stability and reaction kinetics provide the high and stable capacity as well as superior rate capabi…
Rice husk ash (RHA), an agricultural waste, was used as biosorbent for the removal of Iron(II) and Manganese(II) ions from aqueous solutions. The structural and morphological characteristics of RHA and its elemental compositions before and after adsorption of Fe(II) and Mn(II) were determined by scanning electron micr…
An innovative approach is employed for synthesising reduced graphene oxide with antibacterial properties via utilisation of continuous supercritical water (in alkaline medium) which enabled reduction of graphene oxide in a single rapid route and thus eliminating hazardous conventional chemicals.
Active targeting of nanoparticles to receptor-overexpressing cancer cells has great potential for enhancing the cellular uptake of nanoparticles and for reducing fast clearance of the nanoparticles from the body. Herein, we present a preparation method of a porous silicon (PSi)-based nanodelivery system for breast can…
A new, highly selective and sensitive colorimetric chemosensor 1 for detection of Cu(2+) ions in aqueous solution was developed. Receptor 1 detected Cu(2+) ions by changing its color from colorless to yellow. Moreover, the Cu(2+)-sensitive compound was used as a colorimetric pH detector based on a color change due to…
We demonstrate the preparation of cadmium sulfide (CdS) thin films via a facile chemical bath deposition method.
Biomaterials play a crucial role in the field of tissue engineering. They are utilized for fabricating frameworks known as scaffolds, matrices or constructs which are interconnected porous structures that establish a cellular microenvironment required for optimal tissue regeneration. Several natural and synthetic biom…
Reduced graphene oxide (RGO)–TiO 2 nanowire array hierarchical composites were prepared via an in situ controlled growth process and subsequent calcination, and showed much higher H 2 production activity than that of pure TiO 2 and RGO–TiO 2 generated by mechanical mixing.
A model for coalescence/sintering of Pt nanoparticles is developed to analyze particle growth and electrochemical surface area (ECSA) loss measured in aqueous tests and in catalyst-coated membrane and gas diffusion electrode-containing single fuel cells. The model combines a non-ideal solid solution theory for Pt diss…
An ultrasensitive method for surface enhanced Raman scattering (SERS) detection of prostate-specific antigens (PSAs) was established based on the aptamer directed core-satellite nanostructures. A limit of detection (LOD) of 4.8 aM for PSA was obtained.
By stepwise functionalization of a T-shaped ligand with amide and N-oxide groups, we obtained a MOF with drastically strengthened CO2-framework interactions, induced by a "open donor sites" (ODSs) effect, resulting in a high heat of adsorption and high CO2/CH4, CO2/CO and CO2/N2 separation selectivities at room temper…
Boron-doped graphene, synthesized by annealing a mixture of graphite oxide and B2O3, has shown a high conversion efficiency of 6.73% as a counter electrode (CE) for dye-sensitized solar cells, which is better than the Pt CE.
The United States is promoting the establishment of a bio-based economy, generating energy and fuels from renewable organic matters rather than fossil fuels. Byproducts such as fractions of biochar not suitable for biofuel production are drawing extensive attention. (“Biochar” is defined by Oxford's online dictionary…
