Significance Statement

Lipolysis is of particular importance for energy homeostasis in proximal tubular epithelial cells (PTECs), and it is dysregulated during the pathogenesis of diabetic kidney disease. In knockout mice lacking O-GlcNAc transferase specifically in PTECs, the authors demonstrated that protein O-GlcNAcylation, an intracellular nutrient sensing system, is essential for renal lipolysis and ATP production during prolonged fasting. They also found evidence that this novel regulatory mechanism of renal lipolysis involves farnesoid X receptor–dependent upregulation of carboxylesterase-1 and that deficiency of renal protein O-GlcNAcylation exacerbates tubulopathy in diabetic kidney disease. These findings suggest that manipulation of the renal lipolytic mechanism to overcome the effects of prolonged fasting might represent a novel therapeutic approach for diabetic kidney disease.

Background

Energy metabolism in proximal tubular epithelial cells (PTECs) is unique, because ATP production largely depends on lipolysis in both the fed and fasting states. Furthermore, disruption of renal lipolysis is involved in the pathogenesis of diabetic tubulopathy. Emerging evidence suggests that protein O-GlcNAcylation, an intracellular nutrient-sensing system, may regulate a number of metabolic pathways according to changes in nutritional status. Although O-GlcNAcylation in PTECs has been demonstrated experimentally, its precise role in lipolysis in PTECs is unclear.

Methods

To investigate the mechanism of renal lipolysis in PTECs—specifically, the role played by protein O-GlcNAcylation—we generated mice with PTECs deficient in O-GlcNAc transferase (Ogt). We analyzed their renal phenotypes during ad libitum feeding, after prolonged fasting, and after mice were fed a high-fat diet for 16 weeks to induce obesity and diabetes.

Results

Although PTEC-specific Ogt-deficient mice lacked a marked renal phenotype during ad libitum feeding, after fasting 48 hours, they developed Fanconi syndrome–like abnormalities, PTEC apoptosis, and lower rates of renal lipolysis and ATP production. Proteomic analysis suggested that farnesoid X receptor–dependent upregulation of carboxylesterase-1 is involved in O-GlcNAcylation’s regulation of lipolysis in fasted PTECs. PTEC-specific Ogt-deficient mice with diabetes induced by a high-fat diet developed severe tubular cell damage and enhanced lipotoxicity.

Conclusions

Protein O-GlcNAcylation is essential for renal lipolysis during prolonged fasting and offers PTECs significant protection against lipotoxicity in diabetes.
Mechanism of self-propagating hightemperature synthesis of AlB2‒Al2O3
Authors: Yang Pan , Xiao Guoqing , Ding Donghai , Ren Yun , Zhang Zhongwei , Yang Shoulei , Zhang Wei
Published: May 2019

The mechanism of self-propagating high-temperature synthesis (SHS) of AlB2‒Al2O3 composite powders was studied by means of a combustion front quenching method (CFQM). The results showed that combustion reaction started with the melting of B2O3 and Al particles. As the combustion reaction proceeded, the interpenetration of Al and B2O3 in melts happened. The XRD results of the product revealed the reflections of Al2O3, suggesting there had been an exchange of oxygen atoms between Al and B, and evidencing the reaction, B2O3 (l) + 2Al (l) → 2B (s) + Al2O3 (l). Under higher temperature, some of B2O3 volatilized and reacted with B forming gaseous B2O2, which deposited on the surface of Al to precipitate Al2O3 and B. Then B made available dissolved into Al melt, and reacted with the Al in melt to precipitate AlB12 particles. Finally, AlB12 transforms to AlB2 at the peritectic temperature under high cooling rate. Thus, this combustion reaction can be described by the dissolution-precipitation mechanism. In the final products, besides AlB2 and Al2O3 particles, some of Al was also detected. A model corresponding to the dissolutionprecipitation mechanism was proposed, and the ignition temperature of the combustion reaction was determined to be around 800 °C. Ill. 13. Ref. 47.
Effect of heat treatment of quartzite on the mechanism of destruction of the lining of induction furnaces
Authors: Zavertkin A. S.
Published: May 2019

The mechanism of wear of quartzite lining of induction crucible furnaces during the smelting of iron and steel is presented. It has been established that the main cause of lining wear is a decrease in its strength caused by the transition of the tridimite joint into cristobalite, which is much easier to wash off the walls of the crucible with moving metal and slag. The second important factor of wear is the choice of quartzite raw materials, its material and granulometric compositions, the firing mode and the technology of melting during operation of the furnace. Silicon recovery from silica of carbonization lining by carburizer and cast iron, which is part of, is a secondary factor of crucible lining wear. Ill. 4. Ref. 5. Tab. 1.

Authors: Kashcheev I. D. , Zemlyanoy K. G. , Perepelitsyn V. A. , Dzerzhinsky R. V.
Published: May 2019

The results of thermocyclic tests of a number of products of higher refractoriness are given. It is shown that the most resistant to cyclic variable thermal loads are periclase products from fused powders coated with ZrO2. The structure of corundum products in the process of thermocyclic testing significantly degrades due to recrystallization and the formation of new phases. Products made of fused periclase powders modified with ZrO2 are recommended for the organization of the lining and heat exchange tips of test benches that are operated under conditions of variable thermal loads in pulsed piston systems.

Authors: Gulyaeva A. V.
Published: May 2019

The process of torch gunning and applied gunning mass in ferrous metallurgy is investigated. The increase in the durability of the lining of non-ferrous metallurgy heat units was investigated by means of lining repair without stopping the units using the torch gunning method. A special gunning mass has been developed taking into account the specific service conditions of the lining of these units. It has been established that in order to lower the temperature, it is necessary to introduce a low-melting component or thermite mixture into the gunning mass, which operates according to the principle of self-propagating high-temperature synthesis (CBC). The design of the gunning unit was created taking into account the properties of the gunning mass. Tests of new gunships, gunning masses at the non-ferrous metallurgy plants showed an increase in the resistance of linings by 1.8-2.5 times. Ill. 4. Ref. 7. Tab. 2.

Del mundo de lo sensible al universo de lo inteligible en la enseñanza de las ciencias naturales
Authors: González Villate Luz Dary
Published: May 2019

Este artículo presenta una reflexión derivada de investigación en el que se argumenta que así como a la filosofía, a la enseñanza de las ciencias le asiste un doble compromiso: ocuparse de los principios que orientan su actividad (pedagogía) y comprender la gramática de las disciplinas que se propone enseñar (química, física, biología, matemáticas). Respecto al primer compromiso, se argumenta que—durante su formación— el educando establece relaciones con el saber de orden imaginario, simbólico y real, en las que los semblantes de saber del maestro —saber supuesto, expuesto, en reserva y deseo de saber— se constituyen en condición de posibilidad del deseo de saber del educando. En cuanto al segundo compromiso, se exponen algunas reflexiones epistemológicas frente a la tensión presente en las relaciones: experiencia-experimento, experienciaformalización, serendipia-experimento y artefacto-instrumento, para concluir que, en la enseñanza de las ciencias, se transita del mundo de lo sensible al universo de lo inteligible.

¿Cuál es la tarea de la educación? Despertando el deseo de querer existir en el mundo de una manera adulta
Authors: Biesta Gert , Noguera-Ramírez Carlos Ernesto
Published: May 2019

Las discusiones sobre educación a menudo están enfocadas en los propósitos que deberían lograrse o en los resultados que deberían producirse. En este artículo abordamos la cuestión del propósito de la educación de forma diferente, al preguntarnos en qué debería enfocarse el trabajo de los profesores y demás educadores. La respuesta que proponemos es que el objetivo de este trabajo es despertar en los niños y en los jóvenes el deseo de querer existir en este mundo, de la forma que denominamos como “adulta”. Explicamos nuestra idea de “crecimiento”, sobre la que argumentaremos que no deberíamos pensar en ella como el resultado de una trayectoria de desarrollo, sino como una forma en la que los seres humanos pueden tratar de existir en y con el mundo. Esto sugiere que es importante, en el trabajo educativo, interrumpir las formas en las que los niños y los jóvenes están completamente enfocados en sí mismos, llevándolos así al mundo en que solo se puede dar su existencia como sujetos adultos. La educación enfocada en eso tiene la tarea de ofrecer tiempo, espacio y formas curriculares a través de las cuales los niños y los jóvenes puedan trabajar “en” su crecimiento. Adicionalmente, la educación debe proveer sustento para que niños y jóvenes puedan recibir apoyo y nutrirse en su tarea de intentar existir de forma adulta.

Objetivo: Verificar o efeito agudo do pré-condicionamento isquêmico (PCI) sobre a capacidade de realizar esforços intensos de alta demanda aeróbia em basquetebolistas de elite. Métodos: Onze atletas profissionais de basquete (25,4 ± 6,9 anos; 200 ± 10-cm estatura; 97,7 ± 11,2-kg de massa corporal) realizaram de maneira cruzada, randomizada e balanceada o teste YoYo Intermittent Recovery Test Level 1 (YoYoIR1) logo após PCI (4 ciclos de 5-min de isquemia - pressão de 250 mmHg e 5-min de reperfusão - sem pressão externa) ou SHAM (placebo-controle, mesmo procedimento do PCI, porém com pressão de 20 mmHg na fase de “oclusão”). Resultados: Não houve diferença significativa (p = 0,21) entre as condições PCI vs. SHAM (PCI = 35 ± 7,8 estágios do YoYoIR1 vs. SHAM = 37,5 ± 8,2). Conclusão: Agudamente o PCI não promove melhora na capacidade de executar esforços intermitentes-intensos e com alta demanda aeróbia entre jogadores profissionais de elite de basquete.
Discurso político e o ethos coronelista em Esplanada, Bahia
Authors: Silva Elias Ramos da
Published: May 2019

Neste artigo, busca-se investigar a materialidade do ethos coronelista na fala do candidato eleito a prefeito de Esplanada (BA). O corpus é a entrevista concedida ao jornal local Esplanada News, realizada no ano de 2012. O aporte teórico advém da Análise do Discurso desenvolvida por Maingueneau e da Nova Retórica desenvolvida por Perelman e Olbrechts-Tyteca. Também é utilizado o conceito de “coronelismo” de Leal e o conceito de discurso político de Charaudeau. Para abordar o contexto sócio-histórico, dialoga-se com duas obras de Hildeth Cardoso de Faria, pois este autor nos apresenta dados sobre a memória da cidade, em que é possível identificar a presença da cultura do coronelismo. Após término da análise do corpus, verificou-se na fala do prefeito eleito a materialidade de um ethos e de um anti-ethos com algumas marcas da cultura do coronelismo.
O teclado das paixões em cena: Relatos Selvagens e o elo retórico-musical
Authors: Santos Junior Valmir Ferreira dos , Figueiredo Maria Flávia
Published: May 2019

A música detém um caráter altamente envolvente. Conhecimento não tão usual como esse é o de que a música pode objetivar diversos fins argumentativo-persuasivos no que tange às áreas do discurso. Particularmente, a trilha sonora constitui um elemento muito significativo quando aliada às cenas de uma peça cinematográfica. A trilha sonora do sexto episódio de Relatos Selvagens (filme de 2014, dirigido por Damián Szifron), juntamente com as demais linguagens que a acompanham, constitui o corpus do nosso trabalho. O objetivo deste artigo é evidenciar a relação cena-trilha sonora e como tal elo atua em um discurso multimodal de forma argumentativa. Contaremos com conceitos oriundos da teoria musical (como andamento e timbre) e da Retórica (figuras e paixões aristotélicas). Esperamos, por meio de uma análise qualitativa dos dados, desvelar os sentidos criados por meio da inter-relação cena-trilha sonora e os possíveis desdobramentos no que concerne ao pathos (esfera do espectador).
A retórica da pós-verdade: o problema das convicções
Authors: Seixas Rodrigo
Published: May 2019

Eleita “palavra do ano” de 2016 pelos Dicionários Oxford, a pós-verdade é o qualificativo das circunstâncias em que fatos objetivos são menos influentes na opinião pública que os apelos emocionais e as crenças pessoais. Assim posto, seria a pós-verdade não apenas um sinônimo de fake news, mas, sobretudo, de convicção (ANGENOT), vez que, falsas ou verdadeiras, as informações são divulgadas ou excluídas não pela sua veridicidade, mas pela sua adequação às crenças/valores de cada sujeito. Tal indisponibilidade à verificação se daria, em tese, por razão do tipo de racionalidade instrumental, pragmatista e utilitarista (BOUDON), que configura a cognição e a retórica dos sujeitos. Interessa a este artigo, portanto, não o funcionamento e a circulação dos discursos de pós-verdade, mas problematizar o tipo de racionalidade contemporânea como causa do fenômeno, a ponto de se tornar um conceito tão discutido nas Ciências Humanas e Sociais como um todo.
Quando o alter ethos é homofóbico
Authors: Nascimento Lucas
Published: May 2019

Já que o ser humano se constitui intersubjetivamente, é interessante analisar, através da imagem que o sujeito projeta de si, a imagem que o outro faz dele. Esta imagem, chamo-a de alter ethos. Desse modo, ao repousar analiticamente sobre um pronunciamento em uma audiência pública da Comissão de Direitos Humanos, no Senado Federal do Brasil, em 2011, a respeito do Projeto de Lei anti-homofobia (PLC 122/2006), mostro a produtividade dessa noção à luz de uma análise dialógica da argumentação. Esta resulta de um evento epistemológico entre a Filosofia do ato responsável, fundamento do dialogismo de Bakhtin, e a Nova Retórica de Perelman e Olbrechts-Tyteca. Ora, essa perspectiva de análise privilegia não apenas o acordo, mas, sobretudo, a polêmica. Ao final, fica claro como o alter ethos ajuda a compreender o motivo da construção de um ethos, no caso específico, de um ethos anti-homofóbico.

Published: May 2019

RESUMO: As cidades desplugadas, na era da supermodernidade, impelem-nos a discutir, no presente artigo, o termo mobilidade informacional, com a finalidade de desnaturatizá-lo e trazer, à baila, as adversidades subjacentes a essa nova forma de subjetivação, de individuação e de mobilidade. Para lograr êxito nesse processo hermenêutico e investigativo, será utilizado como procedimento metodológico a revisão de literatura, embasada nos seguintes autores: Lemos (2007a, 2007b, 2008, 2009), Rivière (2006) e Tuan (2003). A intenção é de não só discutir as implicações entre mobilidade versus comunicação de massa, o processo de configuração e a reconfiguração do território informacional, mas também empoderar o coenunciador a tornar-se um “bricoleur” da transmodernidade, com o intuito de discutir o conceito de identidade na contemporaneidade e, assim, ressignificar o seu olhar no momento em que participa, colabora no processo de construção de novas maneiras de estabelecer vínculos e laços de pertencimento.

PALAVRAS-CHAVE: mobilidade informacional; cidades desplugadas; individuação; subjetivação.

 

ABSTRACT:

The unplugged cities, in the age of Supermodernity, lead us to discuss the term informational mobility in this article, aiming at denaturalizing it and bringing up underlying adversities to this new manner of subjectivation, individuation and mobility. In order to succeed in this hermeneutic and investigative process, the literature review will be used as methodological procedure, based on the following authors: Lemos (2007a, 2007b, 2008, 2009), Rivière (2006) and Tuan (2003). The intention is not only to discuss the implications between mobility and mass communication, the configuration process and informational territory’s reconfiguration, but also to empower the co-enunciator to become a “bricoleur” of the transmodernity, make possible to discuss the concept of identity in the contemporary society and, thus, to resignify his look at the time he is part of, collaborating in the building process of new ways of establishing links and the belonging feeling.

RESUMO: Este artigo destina-se a identificar as marcações no enunciado do jogo de videogame Super Mario World, de 1990, que permitam enxergar o fluxo da ação de controle operada pelo jogador visado pela enunciação. Para tanto, deve-se estabelecer a distinção entre a instância enunciada do enunciatário, o narratário, a quem o narrador instrui e comanda, e a instância do enunciado enunciado, em que se localiza o herói Mario, aquele comandado pelo narratário. As categorias narrativas e discursivas ora são comuns, ora diversas para esses sujeitos, estruturando graus de sincretismo de suas identidades e de seus percursos. É no percurso do narratário em que são encontradas as dinâmicas sensíveis que demarcam o ritmo do processo de jogo, o tempo necessário para se tornar hábil e vencer.

PALAVRAS-CHAVE: semiótica; videogames; narratividade.

 

ABSTRACT: In this article, our goal is to identify the syntax of control which a video game player plays, in the game Super Mario World, from Nintendo (1990), basing our notes on the many marks left in the audiovisual text, in the form of figures and narrative programs. Therefore, two levels must be distinguished: one concerning the player, referred in the text as a naratee, and another concerning the enounced hero, Mario. The discursive categories and narrative patterns are sometimes the same and sometimes different for each actor, proposing syncretism degrees for their identities and their syntaxes. It is in the course of the naratee that the sensitive dynamics that mark the rhythm of the game process are found, besides the time needed to become skilled and to win.

KEYWORDS: semiotics; video games; narrativity.

Es difícil realizar una descripción de nuestra sociedad actual sin hacer mención a las conexiones que se establecen de forma online gracias a las redes sociales. Es por ello por lo que resulta digno de estudio realizar un análisis comparativo del flujo de consumo de dos importantes aplicaciones: Instagram ySnapchat, siendo su modelo de negocio bastante similar. El objetivo principal es observar la evolución de estas herramientas 2.0, así como comprobar si existe algún tipo de conexión entre el descenso de la popularidad de la aplicación del fantasma y la proliferación de la función de Instagram Stories.Por último, pero no menos importante, se explicarán las nuevas profesiones que han surgido a raíz de este tipo de aplicaciones, especialmente gracias a Instagram, que no sólo ha contribuido al aumento de usuarios de la plataforma,sino que se ha posicionado como una ventana de contacto con ellos. Además ha traído consigo nuevos modelos de negocio de los que tanto marcas como profesionales freelance se están beneficiando.Finalmente, es resaltable la consideración de un futuro incierto de este mundo online que se rige por la preferencia de los usuarios de las aplicaciones que se encuentran de moda en cada momento. Este mercado ofrece la posibilidad de crear nuevas aplicaciones que triunfen entre la población si tienen lascaracterísticas necesarias para satisfacer sus necesidades.
Emotional or rational product labeling using Galvanic Skin Response

In the research on consumer purchasing decisions, there has historically been a constant duality between the presence or absence of emotions and their role. Historically they have been observed as annoyances that interfere with optimalprocess, as it would be rational and cognitive. Since the late 70s, some researches emerged defending the importance of emotional processes in decision-making. The latest studies also persist in the idea that emotions are present in all product purchase decisions. But, does it occur with the same intensity in all types of products? In this research paper, an experiment is proposed to classify different products in two categories, one that concentrates those that generate a more intense emotional response and another with less intensity. This categorization is interesting for those experiments in which it is necessary, either for statistical treatment or for other reasons, grouping products by emotional response.

Este trabajo presenta una investigación realizada acerca de Pinterest. La saturación de los medios tradicionales unido al estancamiento de redes sociales como Facebook y Twitter han provocado que los consumidores centren su atención en otras redes sociales como es el caso de Pinterest. Sin embargo, dado su novedad, las empresas aún no tienen claridad acerca de cómo evitar fracasos y sacar el máximo provecho de esta nueva vía de comunicación. Por lo tanto, este trabajo tiene como objetivo analizar el comportamiento del consumidor chileno en Pinterest. Para ello se realizó un estudio de Pinterest en Chile para conocer las características y las funciones que eran más utilizadas por los usuarios de esta red social, además de cómo interactuaban con las organizaciones. Este estudio es el primero que se realiza formalmente en Chile, por lo que contribuye tanto a la literatura como a la práctica del Marketing online en dicho país.
Amplitud del surtido como generador de emociones negativas en el consumidor
Authors: Gálvez Martínez Marta , López López Inés
Published: May 2019

La decisión de un consumidor de acudir a un establecimiento depende de factores tales como precio, proximidad, surtido, promociones. Cada vez existe mayor preocupación entre fabricante y distribuidor por tener un número de referencias óptimo y lo más diferenciado posible. El presente trabajo tiene como objetivo analizar los efectos que tienen la amplitud del surtido y la implicación con la categoría de producto sobre las emociones que experimenta el consumidor. Se ha aplicado la metodología experimental para la recogida de datos, planteando un diseño entre sujetos 2 x 2, siendo los factores manipulados la amplitud del surtido (amplio vs reducido) y el tipo de producto (baja implicación vs media implicación).

Los resultados indican que no solo el tamaño del surtido influye en el comportamiento, sino que también el tipo de producto juega un papel importante, originando en el consumidor emociones negativas cuando el surtido es grande y el producto es de implicación media. Así, un mayor abanico de posibilidades en términos de surtido no siempre es recomendable, pues puede llegar a saturar al consumidor y generar una respuesta emocional desfavorable. En consecuencia, los directivos de marketing deben encontrar un punto de equilibrio entre una oferta variada y una oferta excesiva, para que los clientes puedan procesar la información de las distintas alternativas y quedar satisfechos con su elección final.
Interprofessional Education for BSW Students: A Pilot Course
Authors: Edwards Claire M. , Newell Jason M.
Published: May 2019

The focus on interprofessional education (IPE) for professional training programs in allied health professions such as social work has increased recently. There is limited pedagogical literature regarding either the instruction or application of IPE in any given profession. Based on a co-teaching model of instruction, this article delineates the preparation and integration process of a pilot course on IPE. The pilot course was taught at a small liberal arts college where it was cross-listed in two undergraduate professional programs in social work and speech-language pathology. This article discusses the relevance of including IPE in allied health professional training programs. Additionally, this article outlines the timeline for developing and implementing the course, from conceptualization to the integration phases including implications from student evaluations of their experience in the course. Elements of the course including delivery, descriptions of assignments, and projects also are discussed.

Background: Pneumonia affects 156 million children under five years every year and is the leading cause of mortality in this age group. It emphasizes the need to identify high risk factors for Treatment Failure so as to treat them aggressively. The objective of this study was to assess factors influencing treatment failure in severe pneumonia treated with Ampicillin.Methods: Prospective observational study, in which 235 children with severe pneumonia between 2 months to 60 months were enrolled and started with intravenous Ampicillin as per WHO protocol. If no clinical improvement was seen after 48 hours, it was taken as treatment failure and managed accordingly.Results: Among 235 children, 43(18.2%) did not respond to Ampicillin. Among treatment failure cases males were 20 (46.5%) and females were 23 (53.6%). All the following parameters were statistically significant(p<0.05). Majority of 23(53.4%) were between 2 to 12 months. 13(30.2%) were incompletely immunized. MAM were 23(53.4%) and 22(51.1%) cases had signs of Rickets. 34(79.1%) had Anemia out of which 22(64%) had moderate anemia. 39(90.6%) children had fever and hypoxia at admission.Conclusions: Infancy, malnutrition, severity of anemia, rickets, lack of immunization, hypoxia at baseline were significant predictors of treatment failure in severe pneumonia. Strengthening immunization and improving nutritional status may improve the outcome. Children with above risk factors require vigilant monitoring.

Child marriage is associated with adolescent pregnancy, which increases maternal and child health risks and rates of child marriage have increased among families affected by the Syrian conflict. Although contraception reduces these risks, data about contraception practices among Syrian child brides is sparse. This cross sectional, descriptive pilot study examined contraceptive knowledge, attitudes, barriers, needs and practices among young Syrian brides. A convenience sample of female Syrian refugees aged 13-25 who had married before the age of 18 was recruited through a civil society organization in Lebanon. Among the 32 participants, there were significant knowledge gaps and negative attitudes towards contraception, with approximately one fifth of participants (18.8%) unaware of contraceptive methods and 84.4% unaware of emergency contraception. Negative attitudes towards contraception were common, including beliefs that it was physically harmful (47.0%), contradicted religious views (43.8%), and lacked support by husbands (50%). The majority of participants (53.1%) had never used contraception with the most common reason being fear of side effects (47%). Approximately one-third (30%) of participants with two or more children reported sub-optimal birth spacing of less than a year and almost one-quarter of participants (24.1%) reported a history of terminating a pregnancy. Notably, one-fifth of participants (20.8%) had an unmet need for contraception, and unwanted pregnancies were common among women who were currently (42.9%) or previously (48.1%) pregnant. Results from this small convenience sample of Syrian child brides in Lebanon identify an urgent need to further explore contraception use among this population and to inform interventions for increased contraception usage to decrease adolescent pregnancies and improve maternal and child health.

The aggregation of sensitizer molecules on the surface of photoanode is a serious issue that can affect the photovoltaic performance of dye-sensitized solar cells. Prevention of dye agglomeration, therefore, is critical. Traditional methods of aggregation control are either synthetically challenging or technologically difficult and expensive. In this article, the use of bis(4-pyridyl)alkanes to control porphyrin dye aggregation is presented. Three bis(4-pyridyl)alkanes – bis(4-pyridyl)butane L4, bis(4-pyridyl)octane L8 and bis(4-pyridyl)decane L10 were synthesized. These bis(4-pyridyl)alkane ligands are axially attached to the metallic center of synthesized porphyrin dye P. The complexes was obtained by mixing the solutions of dye P and each ligand (L) in 2:1 ratio 1 h before the soaking step. As a result three cells were prepared: P-L4, P-L8 and P-L10. The performance of these cells were compared with a reference cell which was prepared from porphyrin dye P only. IPCE analysis demonstrated the highest dye load in P-L4 cell which was ascribed to lowered dye aggregation. Photovoltaic analysis showed improved short circuit current density due to suppressed dye aggregation caused by the complexation of the porphyrin dye P with the linker L4. As a result the overall cell efficiency increased to 42% demonstrating the successful utilization of the (4-pyridyl)alkane linker complexes with porphyrin dye.
