Abstract:
In this study two pairs of novel zinc-porphyrin complexes (ZnP1 ZnP2 ZnP3 and ZnP4) were synthesized as sensitizers for DSSC and their photophysical, computational studies and photovoltaic properties were investigated. Structures of proposed dyes are based on a molecular design that relies on donor/[Formula: see text]-bridge/acceptor interactions. Compounds differ by anchoring mode to the titanium dioxide surface: ZnP2 and ZnP4 porphyrins possess carboxyl anchoring groups while ZnP1 and ZnP3 porphyrins have similar structure but without anchors and attached to the surface by isonicotinic acid ligands. All the zinc-porphyrin derivatives bear hexyloxy-chains at the para-positions of their phenyl rings and ZnP3 and ZnP4 contain 1,3,5-triazine fragments as efficient electron transfer bridges. Electron density distribution of the frontier molecular orbitals was calculated based on the density functional theory (DFT). The test DSSC was manufactured and its parameters were measured to compare the effectiveness of the proposed sensitizers. Our results reveal that dyes with an anchoring group directly in their structure demonstrated several times higher efficiency. The use of the triazine fragment proved effective for the introduction of acceptor substituents bearing anchor groups. As a result, the highest efficiency of 4.33% was achieved using the dye ZnP4.

Abstract:
Zinc pyrithione (ZnPT) is an anti-fungal drug delivered as a microparticle to skin epithelia. It is one of the most widely used ingredients worldwide in medicated shampoo for treating dandruff and seborrheic dermatitis (SD), a disorder with symptoms that include skin flaking, erythema and pruritus. SD is a multi-factorial disease driven by microbiol dysbiosis, primarily involving Malassezia yeast. Anti-fungal activity of ZnPT depends on the cutaneous availability of bioactive monomeric molecular species, occurring upon particle dissolution. The success of ZnPT as a topical therapeutic is underscored by the way it balances treatment efficacy with formulation safety. This review demonstrates how ZnPT achieves this balance, by integrating the current understanding of SD pathogenesis with an up-to-date analysis of ZnPT pharmacology, therapeutics and toxicology. ZnPT has anti-fungal activity with an average in vitro minimum inhibitory concentration of 10–15 ppm against the most abundant scalp skin Malassezia species (Malassezia globosa and Malassezia restrica). Efficacy is dependent on the targeted delivery of ZnPT to the skin sites where these yeasts reside, including the scalp surface and hair follicle infundibulum. Imaging and quantitative analysis tools have been fundamental for critically evaluating the therapeutic performance and safety of topical ZnPT formulations. Toxicologic investigations have focused on understanding the risk of local and systemic adverse effects following exposure from percutaneous penetration. Future research is expected to yield further advances in ZnPT formulations for SD and also include re-purposing towards a range of other dermatologic applications, which is likely to have significant clinical impact.

Abstract:
Two zinc porphyrins substituted at the meso-positions with different donor units (denoted as ZnP1 and ZnP2) have been designed and synthesized to construct new self-assemblies (denoted as ZnPx-ZnPA) with anchor porphyrin (ZnPA) dyads formed by the coordination bonds of Zn-to-ligand approach. Then these assemblies were absorbed on the semiconducting TiO2 electrode surfaces by the carboxylic groups of anchor porphyrin (ZnPA) to build dye sensitized solar cells. Their spectral properties, electrochemical, theoretical calculations and photovoltaic properties were systematically investigated. Interestingly, these self-assemblies devices compared to monomer anchoring porphyrin device showed higher [Formula: see text] and [Formula: see text]. Especially, the dyad of ester-based zinc porphyrin (ZnP2) assembly device has the highest photoelectric conversion efficiency. The assembled modes of the assemblies immobilized on TiO2 electrode surfaces were also verified by transmission electron microscopy (TEM).

This paper reports ZnPt bimetallic nanoparticles (ZnPtBNs) synthesis through the liquid phase deposition (LPD) of of Zn(NO3)2.6H2O onto the indium-titanium oxide (ITO) substrates at various concentrations. The Effects of growth solution, the morphology, structural, and sheet resistance were studied. After preparation, the materials were characterized by using field emission electron microscopy (FESEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD) and Four Point Probe (FPP) measurement by using Keithley 2401 source-meter. By inserting a growth solution into the ITO substrate the ZnPtBNs was successfully in-situ prepared. The synthesized ZnPtBNs exhibited homogeneous, fibrous at the (111) orientation with an average diameter of 100-700 nm. The atomic ratio of Zn:Pt and sheet resistance of ZnPtBNs decreased with the increase of Zn(NO3)2.6H2O concentration. The optimal elemental composition of the sample was at a ratio of Zn:Pt (1:25) obtained at 0.467 mM of Zn(NO3)2.6H2O. It showed the smallest sheet resistance (13.41 ?) which was 38% lower than the ITO sheet resistance (18.44 ?).

Abstract:
L'érythroblaste, qui dispose d'une quantité de fer normale, synthétise de l'hémoglobine en plusieurs étapes, dont la dernière est l'incorporation de Fe++ dans la protoporphyrine sous l'action de la ferrochélatase mitochondriale. Lorsque pour une raison ou une autre, l'érythroblaste manque d'ions Fe++, la ferrochélatase va incorporer du Zn++ à la place et synthétiser ainsi la ZnPP. Son augmentation signale donc une déficience de Fe++ au niveau des mitochondries des érythroblastes. Après avoir étudié la ZnPP dans un certain nombre de pathologies connues pour avoir des répercutions sur le métabolisme du fer et l'érythropoïèse, nous arrivons à la conclusion que la ZnPP n'est pas destinée à remplacer un paramètre du bilan hématologique martial, mais constitue une information supplémentaie précieuse dans l'exploration de tous les désordres du métabolisme du fer

Uma das alternativas mais promissoras para o tratamento do câncer é a Terapia Fotodinâmica (TFD). A Ftalocianina de Zinco (ZnPc) é um fotossensibilizante de segunda geração com caráter hidrofóbico e necessita ser incorporado em um sistema de liberação adequado para ser injetado sistemicamente. Nanopartículas magnéticas, NPMs, constituída principalmente de magnetita (Fe3O4) apresentam alto valor de magnetização com grande potencial de aplicação no tratamento do câncer por hipertermia. O encapsulamento simultâneo de fármacos com NPMs tem sido reconhecido como uma técnica promissora para o tratamento do câncer por possibilitar a ação sinergética dos diferentes tipos de tratamento. O objetivo deste trabalho foi a síntese, caracterização e avaliação da toxicidade e fototoxicidade das NPMs, do encapsulamento da NPMs e ZnPc e o encapsulamento simultâneo de ZnPc com NPMs via polimerização em miniemulsão. As NPMs com ácido oléico (AO) foram preparadas pelo método de co-precipitação em meio aquoso e a análise de DRX mostrou picos característicos da magnetita (Fe3O4) com diâmetro médio de nanopartículas de 13nm. As NPMs apresentaram um alto valor de magnetização de saturação (Ms) (64 emu/g óxido de ferro). O encapsulamento das NPMs foi realizado via polimerização em miniemulsão com metacrilato de metila (MMA). As NPMs encapsuladas apresentaram um diâmetro aproximado de 100nm com valor de Ms de 34 emu/g de óxido de ferro. Para o encapsulamento da ZnPc utilizou-se duas técnicas de encapsulamento. A primeira foi a técnica de miniemulsão com auxílio da técnica de nanoprecipitação (PMMA/ZnPc)(FA)) e a segunda utilizou-se apenas a técnica de miniemulsão direta (PMMA/ZnPc(FO)). O teor de ZnPc nas nanopartículas poliméricas foi um pouco superior na amostra PMMA/ZnPc(FA) (3,7µg/mg) do que na amostra de PMMA/ZnPc(FO) (3,0 µg/mg). Ambas as técnicas resultaram em um tamanho médio de aproximadamente 100nm. Ao encapsular a ZnPc simultaneamente com as NPMs (PMMA/ZnPc/NPMs) não alteração em relação ao tamanho das nanopartículas (100nm), concentração de ZnPc (3,6 µg/mg) e propriedades magnéticas (31 emu/g de óxido de ferro) em relação ao encapsulamento em separado da ZnPc e NPMs. A liberação da ZnPc das nanopartículas poliméricas foi sustentada e lenta. Nas primeiras 20 horas cerca de 5-10% do ZnPc contida nas nanopartículas poliméricas foi liberada em todas as amostras. No ensaio de toxicidade (ausência de luz), as nanopartículas encapsuladas mostraram baixa toxicidade. No ensaio de atividade fotobiológica, observou-se, que a luz isoladamente (sem nanopartículas contendo ZnPc) não foi capaz de induzir efeito citotóxico sobre a cultura de células. Ao utilizar nanopartículas contendo ZnPc observou-se uma redução acentuada da viabilidade celular para 22% (PMMA/ZnPc(FA)) e 30% (PMMA/ZnPc/NPMs).

Abstract : Photodynamic therapy (TFD) is one of the most promising alternatives for the treatment of the cancer. Zinc phtalocyanine (ZnPc) is a second generation photosensitizer with hydrophobic character that should be incorporated in a suitable delivery system to be injected systemically. Magnetics nanoparticles (NPMs) consisting mainly of magnetite (Fe3O4) present high value of magnetization with great potential of application in the treatment of the cancer by hyperthermia. The simultaneous encapsulation of drugs with NPMs has been recognized as one promising technique for the treatment of the cancer making possible a synergetic action of the different types of treatment. The objective of this work was the synthesis, characterization and evaluation of the toxicity and phototoxicity of the NPMs, the encapsulation of the NPMs and ZnPc and the simultaneous encapsulation of ZnPc with NPMs by miniemulsion polymerization. The NPMs with oleic acid (AO) had been prepared by the co-precipitation method in aqueous solution. DRX analysis showed characteristic peaks of magnetite (Fe3O4) with average particle diameter of 13nm. The NPMs had presented high value of magnetization of saturation (Ms) (61 emu/g of iron oxide). The encapsulation of the NPMs was carried through methyl methacrylate (MMA) miniemulsion polymerization. The polymeric particles with NPMs encapsulated presented an average diameter of 100nm with value of Ms of 34 emu/g of iron oxide. Two techniques of encapsulation were employed for the encapsulation of ZnPc. The first one was the miniemulsion polymerization with the nanoprecipitation technique (PMMA/ZnPc) (FAN)) and second one used only the miniemulsion polymerization technique (PMMA/ZnPc (FO)). The amount of ZnPc in polymeric nanoparticles was higher in PMMA/ZnPc(FA) sample (3,7µg/mg) when compared to the sample of PMMA/ZnPc (FO) (3,0 µg/mg). Both techniques resulted in polymeric nanoparticles with an average diameter of approximately 100nm. The simultaneous encapsulation of ZnPc with NPMs (PMMA/ZnPc/NPMs) presented very similar values of average particle size (100nm), concentration of ZnPc (3,6 µg/mg) and magnetic properties (31 emu/g of iron oxide) when compared to the single encapsulation of ZnPc and NPMs. The release of the encapsulated ZnPc was supported and slow. In the first 20 hours approximately 5-10% of the encapsulated ZnPc was released in all samples. In the toxicity assay (light absence), the encapsulated nanoparticles had shown low toxicity. In the assay of phototoxicity activity, it was observed that the light (without polymeric nanoparticles containing ZnPc) was not able to induce cytotoxic effect on the culture of cells. When using polymeric nanoparticles with encapsulated ZnPc an accentuated reduction of the cellular viability of 22% (PMMA/ZnPc (FA)) and 30% (PMMA/ZnPc/NPMs) was observed.

Abstract:
The field of hybrid electronics of molecules and traditional semiconductors is deemed to be a realistic route towards possible use of molecular electronics. Such hybrid electronics finds its potential technological applications in nuclear detectors, near-infrared detectors, organic thin film transistors and gas sensors. Specifically Metal / organic / n-Silicon structures in this regard are mostly reported to have two regimes of charge transport at lower and higher applied voltages in such two terminal devices. The fact is mostly attributed to the change in conduction mechanism while moving from lower to higher applied voltages. These reports describe interactions between the semiconductors and molecules in terms of both transport and electrostatics but finding the exact potential distribution between the two components still require numerical calculations. The challenge in this regard is to give the exact relations and the transport models, towards practical quantification of charge transport properties of metal / organic / inorganic semiconductor devices. Some of the most exiting questions in this regard are; whether the existing models are sufficient to describe the device performances of the hybrid devices or some new models are needed? What type of charge carriers are responsible for conduction at lower and higher applied voltages? What is the source of such charge carriers in the sandwiched organic layer between the metal and inorganic semiconductors? How the transition applied voltage for the change in conduction mechanism is determined? What is the role of dopants in the organic layer semiconductors? What are the possible explanations for observed temperature effects in such devices? In present work the charge transport properties of metal / metal-phthalocyanine / n-Si structures with low (ND = 4×1014 cm-3), medium (ND = 1×1016 cm-3) and high (ND = 2×1019 cm-3) doped n-Si as injecting electrode and the effect of air exposure of the vacuum evaporated metal-phthalocyanine film in these structures is investigated. The results obtained through temperature dependent electrical characterizations of the structures suggest that in terms of dominant conduction mechanism in these devices Schottky-type conduction mechanism dominates the charge transport in low-bias region of these devices up to 0.8 V, 0.302 V and 0.15 V in case of low, medium and high doped n-Silicon devices. For higher voltages, in each case of devices, the space-charge-limited conduction, controlled by exponential trap distribution, is found to dominate the charge transport properties of the devices. The interface density of states at the CuPc / n-Si interface of the devices are found to be lower in case of lower work function difference at the CuPc / n-Si interface of the devices. The results also suggest that the work function difference at the CuPc / n-Si interface of these devices causes charge transfer at the interface and these phenomena results in formation of interface dipole. The width of the Schottky depletion region at the CuPc / n-Si interface of these devices is found to be higher with higher work function difference at the interface. The investigation of charge transport properties of Al / ZnPc / medium n-Si and Au / ZnPc / medium n-Si devices suggest that the Schottky depletion region formed at the ZnPc / n-Si interface of these devices determines the charge transport in the low-bias region of both the devices. Therefore, the Schottky-type (injection limited) and the space-charge-limited (bulk limited) conduction are observed in the low and the high bias regions of these devices, respectively. The determined width of the Schottky depletion region at the ZnPc / n-Si interface of these devices is found to be similar for both the devices, therefore, the higher work function difference at the metal / ZnPc interface of the devices has no influence on the Schottky depletion region formed at the ZnPc / n-Si interface of the devices. The similar diode ideality factor, barrier height and the width of the Schottky depletion region, determined for both of these devices, demonstrates that these device characteristics originate from ZnPc / n-Si interface of these devices. Therefore, the work function difference at the metal / ZnPc interface of these devices has no noticeable influence on the device properties originating from ZnPc / n-Si interface in these devices. The investigation of charge transport properties of Al / CuPc / low n-Si devices with and without air exposure of the CuPc film, before depositing metal contact demonstrate that Schottky-type conduction mechanism dominates the charge transport in these devices up to bias of 0.45 V in case devices with the air exposure, and up to 0.8 V in case devices without the air exposure. This decrease in the threshold voltage, for the change in conduction mechanism in the devices, is attributed to wider Schottky depletion width determined at the CuPc / n-Si interface of the devices without the air exposure of CuPc film. For higher voltage the space-charge-limited conduction controlled by exponential trap distribution, is found to dominate the charge transport properties of the devices without the air exposure of CuPc, and in case of devices with the air exposure of CuPc film, the SCLC is controlled by single dominating trap level probably introduced by oxygen impurities.

Abstract:
Le zinc est un oligo-élément essentiel pour la vie. Le zinc n'est pas seulement un nutriment important, ou un cofacteur de nombreuses enzymes et de facteurs de transcription, il est désormais considéré comme un médiateur intracellulaire. L'homéostasie du zinc résulte de la coordination de diverses protéines: les ZIP, les métallothionéines et les ZnT appartenant à la famille CDF. Le récent décryptage du génome humain a permis d'identifier de nouveaux gènes, ainsi nous avons pu caractériser deux nouveaux gènes de la famille SLC30, nommés SLC30A8 et SLC30A JO. L 'homéostasie du zinc est maintenue par l'action de ces protéines dont la transcription est ellemême dépendante en partie de la concentration en zinc extracellulaire. En cas de carence, les taux de transcription de ZnT -S,-Sc et 7 sont augmentés. Ces transporteurs, que nous avons localisés au niveau de l'appareil de Golgi, pourraient permettre aux protéines néo-synthétisées l'apport en zinc nécessaire à leur fonctionnalité. Nous avons également montré que la protéine ZnT-8 est un transporteur du zinc spécifique des cellules sécrétrices d'insuline, localisé au niveau même des vésicules contenant l'insuline, et dont la régulation de la transcription, tout comme l'insuline, est dépendante du taux de glucose extracellulaire. Le zinc est impliqué dans tous les aspects métaboliques et structuraux des différents compartiments cellulaires. C'est pourquoi la connaissance de ce contrôle cellulaire du zinc est indispensable à une modélisation et à une compréhension du fonctionnement de la cellule
Zinc is an essential trace element. It is involved in many cellular processes because it is a cofactor of enzymes, nuc1ear factors and hormones. Therefore, is a very important component of cell viability Zinc homeostasis results from a coordinated regulation of different proteins: ZIP (uptake), metallothioneins (intracellular storage/trafficking), and ZnT (excretion). Using genomic databanks, we have analyzed and identified two novel SLC30 genes: SLC30A8 and SLC30A10. Zinc homeostasis is maintained by the action of these proteins, and their transcription is partly dependent of extra cellular zinc concentration. Ln case of zinc deficiency, ZnT-5, -5c and -7 genes are over-expressed. These transporters that we have localized in the Golgi apparatus could provide essential zinc to neo-synthesised proteins for their functionality. Furthermore, we showed that ZnT-8 is a zinc transporter specifie of pancreas and expressed in beta cells. ZnT -8 facilitates the accumulation of zinc from the cytoplasm into insulin vesic1es, and its transcription regulation is dependent, like insulin, of extra cellular glucose concentration. Zinc is implicated in all metabolic and structural aspects of the different cellular compartments. Therefore the cellular control of Zinc requires to be understood and is essential tot fear the cellular working

Abstract:
Dielectric elastomers are an emerging class of electroactive polymers for electromechanical transduction. A broad application of dielectric elastomer actuators (DEA) is limited by the high voltage necessary to drive such devices. The development of novel elastomers offering better intrinsic electromechanical properties is one way to solve the problem. Therefore we prepared composites from thermoplastic or thermoset silicone elastomers and organic fillers as phthalocyanines or doped polyaniline (PANI). We studied the mechanical properties of silicones, synthesized, modified and characterized phthalocyanines and doped PANI. The influence of humidity onto the dielectric properties of CuPc(COOH)8 and ZnPc(COOH)8 was analyzed in detail. First measurements of silicone/PANI blends results in a hundredfold increase for the dielectric constant and an electromechanically strain of 8.5%.
