Surface plasmons and effects of losses in propagating modes in a chain of silver nanoparticles
(2016-04-28)
In this work a chain of 4000 silver nanoparticles embedded in a glass medium is considered, and
its leftmost particle is excited by an electric field pulse of Gaussian shape. Considering Drude’s
model, losses of the ...
Thermal stability and crystallochemical analysis for CoII based coordination polymers with TPP and TPPS porphyrins
(RSC Publishing, 2013-03-16)
Two new CoP–bipy compounds have been synthesised and characterised, where P is TPP for compound 1 (TPP = meso-tetraphenylporphyrin) and TPPS for compound 2 (TPPS = meso-tetraphenylporphinetetrasulfonic
acid tetrasodium ...
Pretreatment with Resveratrol Prevents Neuronal Injury and Cognitive Deficits Induced by Perinatal Hypoxia-Ischemia in Rats
(Public Library Science, 2015-11-06)
Despite advances in neonatal care, hypoxic-ischemic brain injury is still a serious clinical problem, which is responsible for many cases of perinatal mortality, cerebral palsy, motor impairment and cognitive deficits. ...
Efficacy of a cognitive and behavioural psychotherapy applied by primary care psychologists in patients with mixed anxiety-depressive disorder: a research protocol
(Biomed Central, 2015-03-20)
Background: In contrast with the recommendations of clinical practice guidelines, the most common treatment for anxiety and depressive disorders in primary care is pharmacological. The aim of this study is to assess the ...
Fitting BICEP2 with defects, primordial gravitational waves and dust
(IOP Publishing, 2015)
In this work we discuss the possibility of cosmic defects being responsible for the B-mode signal measured by the BICEP2 collaboration. We also allow for the presence of other cosmological sources of B-modes such as ...
Self-assembly of iron TCPP (meso-tetra(4-carboxyphenyl)porphyrin) into a chiral 2D coordination polymer
(Elsevier, 2011-08-16)
Synthetic metalloporphyrin complexes are often used as analogues of natural systems, and they can be used for the preparation of high-dimensional coordination polymers. In this work, a new chiral Fe-TCPP (TCPP is ...
Heterogeneous catalytic properties of unprecedented m-O-[FeTCPP]2 dimers (H2TCPP = meso-tetra(4-carboxyphenyl)porphyrin): unusual superhyperfine EPR structure
(RSC Publishing, 2015-01-07)
During the past years, a great effort has been devoted to the anchoring of catalysts into solid coordination networks in order to achieve heterogeneous catalysts. In this sense, an innovative approach consists on using the ...
Mother structures related to the hexagonal and cubic close packing in Cu24 clusters: solvent-influenced derivatives
(RSC Publishing, 2015-05-07)
Compound 1 [Cu24(m BDC)24(DMF)20(H2O)4]• 24DMF•40H2O (m-BDC is 1,3-benzenedicarboxylate and DMF is N,N-dimethylformamide) has been synthesized and structurally characterized by X-ray diffraction. It consists of Cu24-clusters ...
Characterization of cobalt based TPP-bipy coordination polymer
(2016-04-22)
Metalloporphyrin systems are one of the cornerstones on which the existence of life is based, as major biochemical, enzymatic and photochemical functions depend on the special properties of the tetrapyrrolic macrocycle. ...
Dehydration for a solid coordination network based on CuII-(py)2C(OH)2 trimers
(2016-04-22)
Materials consisting of metal ions or clusters that are linked by polyfunctional organic ligands form networks
of different dimensionalities. Their structural features, including large cavities and high surface areas, ...
