Six-coordinate ferric porphyrins containing bidentate N-t-butyl-N-nitrosohydroxylaminato ligands: structure, magnetism, IR spectroelectrochemisty, and reactivity
NONOates (diazeniumdiolates) containing the [X{N2O2}](-) functional group are frequently employed as nitric oxide (NO) donors in biology, and some NONOates have been shown to bind to metalloenzymes. We report the preparation, crystal structures, detailed magnetic behavior, redox properties, and reactivities of the fir…

Electrical current induced reversible tuning of the optical properties of ordered silver gratings.
Accumulation and transformation of nanomaterials in ecological model organisms investigated by using synchrotron radiation techniques
Application of SR techniques to study the accumulation and transformation of engineered nanomaterials in different model organisms of terrestrial, aquatic and atmospheric systems.
Corrosion of Steel Pipelines Transporting Hydrocarbon Condensed Products, Obtained from a High Pressure Separator System: A Failure Analysis Study
In this paper, the corrosion of steel pipelines transporting hydrocarbon condensed products was studied. Different activities of sampling and analysis were carried out to diagnose the failure causes and to establish a control system for the corrosion problem. The combination of three types of corrosion, including eros…
Structure and magnetic properties of an unusual homoleptic iron( iii ) thiocyanate dimer
We describe the structural and variable temperature magnetic susceptibility properties of an unusual homoleptic bimetallic iron(III) thiocyanate tetraanion. This work represents the first structurally characterized bis(μ-1,3-thiocyanato) dimer of iron(III). A weak antiferromagnetic exchange interaction is observed bet…
Preparation of water-dispersible graphene using N-methylmorpholine N-oxide monohydrate and its application for the preparation of nanocomposites using PEDOT
SEM and TEM images (inset: selective area electron diffraction (SAED) pattern) of mono-layered water dispersible graphene (GPN) sheet by treatment of <italic>N</italic> -methylmorpholine <italic>N</italic> -oxide monohydrate (NMMO <sub>m</sub> ).
Intra-molecular magnetic exchange interaction in the tripyridinium bis[tetrachloroferrate( iii )] chloride molecular magnet: a broken symmetry-DFT study
The investigation of magnetic ordering in magnetic molecular conductors is the subject of ongoing research studies in the fields of condensed matter physics, chemistry and material sciences. Following the photo-magnetic behavior already observed in individual (FeCl4)2(py·H)3Cl molecules at room temperature, magnetic o…
Fluorescence microscopy and spectroscopy of subsurface layer dynamics of polymers with nanometer resolution in the axial direction
We studied the dynamics in ultrathin subsurface layers of an amorphous polymer by the spectra of single fluorescent molecules embedded into the layer by vapor deposition and subsequent controlled diffusion to the desired depth in ≈0.5 nm steps. The spectral trails of single molecules were recorded at 4.5 K as a functi…
Luminescence Performance of Yellow Phosphor SrxBa1−xTiO3: Eu3+, Gd3+ for Blue Chip
The Sr x Ba 1− x TiO 3 : Eu 3+ , Gd 3+ phosphors are synthesized by high temperature solid‐phase method. Multiple techniques including X‐ray diffraction (XRD), and scanning electron microscopy (SEM) are used to examine the surface morphology and structural properties of Sr x Ba 1− x TiO 3 : Eu 3+ , Gd 3+ phosphors. Th…
Kinetic Study of Curing Phenol-Formaldehyde/Tannin-Formaldehyde Composite Resins
This work presents a study on the uses of tannin-formadehyde derivative into phenolic resins. Eucalyptus tannins (T) were reacted with formaldehyde to form tannin-formaldehyde resin (TF). Then this derivative was used to prepare tannin-formaldehyde/phenol-formaldehyde resins (TFPF) at 20 and 40 %w/w. The kinetic value…
Bleach etches nanosilver: HOCl-responsive drug delivery system to target leukemic cells
In addition to their well-known antibacterial property, silver nanoparticles (Ag NPs) have also been highlighted as anti-leukemic agents; however, the underlying mechanism responsible for inhibiting the growth of hematopoietic cancer cells is so far poorly understood. In previous reports, Ag NP-induced oxidative stres…
pH-operated hybrid silica nanoparticles with multiple H-bond stoppers for colon cancer therapy
Controlled delivery of a chemotherapeutic drug from pH-sensitive hybrid silica nanocarriers efficiently targets colon carcinoma cells. The drug, blocked by cyanuric acid as stopper, is autonomously released inside the cancer cells.
A Cost-efficient Solution-based Process for the Development of ZnO Nanostructures: A Comprehensive Study of the Role of the Seeding Layer Formation Conditions
