Abstract High‐valent cobalt‐oxo intermediates are proposed as reactive intermediates in a number of cobalt‐complex‐mediated oxidation reactions. Herein we report the spectroscopic capture of low‐spin (S=1/2) CoIV‐oxo species in the presence of redox‐inactive metal ions, such as Sc3+, Ce3+, Y3+, and Zn2+, and the inves…
Enhanced oil recovery by low salinity water (LSW) injection in carbonate reservoirs constitutes one of the main interests for petroleum industry. A molecular mechanism involving acid oil components and the replacement of surface Ca atom by Mg atom has been proposed. To determine the thermodynamic feasibility of this m…
We present the first magnetic phase of an ionic liquid with anion-π interactions, which displays a three-dimensional (3D) magnetic ordering below the Néel temperature, TN = 7.7 K. In this material, called Dimim[FeBr4], an exhaustive and systematic study involving structural and physical characterization (synchrotron X…
The potential of oxidoreductases, such as laccases and peroxidases, to remove organic pollutants from industrial wastewater and process water is addressed in this short review, with an emphasis on the peroxidase work completed or in progress in the authors’ laboratory. The major drawback to this treatment is the cost…
Laser interference lithography is utilized to fabricate large‐area plasmonic antenna substrates for surface‐enhanced infrared absorption (SEIRA). Changing the interference condition in each exposure process allows precise control over the geometrical parameters of the structures and thus tailoring of their optical res…
In the context of the development of new electron mediators for dye-sensitized solar cells that could efficiently substitute the more common I3(-)/I(-) redox couple, we have prepared a series of Cu(I)- phenanthroline complexes through an easy synthetic route. The novel [Cu(2-mesityl-4,7-dimethyl-1,10-phenanthroline)2]…
We studied the effects of high-pressure annealing (HPA) on InGaZnO (IGZO) thin-film transistors (TFTs). HPA was proceeded after TFT fabrication as a post process to improve electrical performance and stability. We used N2 as the pressurized gas. The applied pressures were 1 and 3 MPa at 200 °C. For N2 HPA under 3 MPa…
A Na2MnPO4F/C nanocomposite material is successfully synthesized via spray drying, followed by a high-temperature sintering method. It is shown that the highly phase-pure Na2MnPO4F with symmetry of the P21/n space group is uniformly embedded in the carbon networks, which play a key role in building up a highly efficie…
We propose a novel template-assisted strategy to prepare nanometer-sized manganese oxide (nano-MnO2) by self-assembly of some MnO2 platelets and demonstrate its application as a new class of biosensing platform for probing DNA hybridization and aptamer-target interaction in a homogeneous solution.
In this work, the authors demonstrate the potential of epitaxially grown highly doped InSb as an engineered, wavelength-flexible mid-IR plasmonic material. The authors achieve doping concentrations over an order of magnitude larger than previously published results and show that such materials have plasma frequencies…
Reservoir silting is an unavoidable issue. It is estimated that in Italy, the potential rate of silting-up in large reservoirs ranges from 0.1% to 1% in the presence of wooded river basins and intensive agricultural land use, respectively. In medium and small-sized reservoirs, these values vary between 0.3% and 2%. Co…
The Monte Carlo simulation of the interaction of neutrons with matter relies on evaluated nuclear data libraries and models. The evaluated libraries are compilations of measured physical parameters (such as cross sections) combined with predictions of nuclear model calculations which have been adjusted to reproduce th…
We report a complete analysis of model silica/styrene–butadiene rubber (SBR) nanocomposites including a direct and quantitative correlation between the filler structure and the mechanical reinforcement. We compared two different ways of sample processing: a solvent casting route with well-defined colloidal silica and…
Anions stabilize stacking of C5-symmetric macrocycles, called cyanostars, into dimers in solution and herein we demonstrate this stacking in solid-state crystals. We further show that this guest binding can be applied as a route to bilayer growth at the solution-graphite interface.
Reaction of Co(NCS)2 with 1,2-bis(4-pyridyl)-ethane (bpa) leads to the formation of [Co(NCS)2(bpa)2]n, which, on heating, transforms into the new layered coordination polymer [Co(NCS)2(bpa)]n. This compound can also be prepared in solution, but because no reasonable single crystals are available, its crystal structure…
A simple and effective approach was demonstrated to synthesize flowerlike Pt nanocrystals on polydopamine (PDA) functionalized reduced oxide graphene (RGO). Inspired by mussels, the PDA/RGO composites were obtained via the reduction of GO nanosheets by dopamine, followed by simultaneous capping by PDA. Then, the synth…
Significance: Chronic wounds are known to be a significant issue globally. Of concern in wounds are the numbers and types of residing microorganisms and the ability of the host's immune system to control their proliferation. Wound healing is impeded by colonizing microorganisms growing within the biofilm phenotypic st…
A novel hydrophobic metal-organic framework (MOF), namely Cu2 L (L = 3,3',5,5'-tetraethyl-4,4'-bipyrazolate), is synthesized through a stepwise method, and exhibits an unprecedented 3,4-c net. The exceptionally thermal, chemical, and air stability of this MOF, especially in water and under acidic or basic conditions,…
In this work, novel uniform Cu2O nanocrystals (NCs) with a size of 4 nm were synthesized by a remarkably simple and facile route via a synproportionation reaction of Cu2+ with metal copper powder at room temperature. The obtained Cu2O NCs as an integrated photocatalytic adsorbent (IPCA) exhibited high adsorption affin…
Nerve conduits are promising alternatives for repairing nerve gaps; they provide a close microenvironment that supports nerve regeneration. In this sense, histological analysis of axonal growth is a determinant to achieve successful nerve regeneration. To evaluate this process, the most-used immunohistochemical marker…
