Facile synthesis of nanoparticles titanium oxide as high-capacity and high-capability electrode for lithium-ion batteries

Anatase TiO2 is prepared via a facile and eco-friendly synthesis method where titanium tetra isopropoxide and sodium alginate are used as the titanium precursor and templating agent, respectively. Structural characterization of the prepared sample via X-ray diffraction and Raman spectroscopies confirm the formation of nanoparticles Titanium Oxide with anatase type structure without impurities. Further morphological characterization of the material showed the spherical shape of the particles. The prepared TiO2 has been studied as an anode material for lithium-ion batteries. TiO2 electrodes have delivered a reversible capacity of 266 mAh g(-1), 275 mAh g(-1) with coulombic efficiencies of 70%, 75% during the first cycle under C/10 current rate for TiO2 calcined at 300 degrees C and 450 degrees C, respectively. The activity of Ti4+/Ti3+ redox couple during the lithiation/delithiation process was evidenced using X-ray Photoelectron Spectrometry. The high capacity retention was maintained for 100 cycles. The prepared nanoparticles TiO2 has prodigious potential for large scale production of anode materials for lithium-ion batteries

Değerin birlikte yaratımı ve yıkımı bağlamında showroomıng davranışı üzerine bir araştırma

06.03.2018 tarihli ve 30352 sayılı Resmi Gazetede yayımlanan “Yükseköğretim Kanunu İle Bazı Kanun Ve Kanun Hükmünde Kararnamelerde Değişiklik Yapılması Hakkında Kanun” ile 18.06.2018 tarihli “Lisansüstü Tezlerin Elektronik Ortamda Toplanması, Düzenlenmesi ve Erişime Açılmasına İlişkin Yönerge” gereğince tam metin erişime açılmıştır.Tüketiciler son yıllarda bilgiye ulaşım kanallarının çeşitlenmesiyle bilgi asimetrisinde avantajlı duruma geçmeye başlamıştır. Bu avantajlarını kendi fayda maksimizasyonları için kullanan tüketiciler perakende kanallarını çapraz bir şekilde değerlendirmektedir. Bu da tüketicilere ürün ve hizmetleri en uygun koşullarda elde etme imkanı vermektedir. Showrooming olarak adlandırılan fiziki mağazada araştırıp çevrimiçi mağazadan satın alma davranışı perakende işletmeleri için üzerinde düşünülmesi gereken önemli konulardan biridir. Bu çalışmanın amacı, showrooming davranışının üzerinde etkili olan tüketici ve kanal karakteristikleri ile ilgili unsurların mağazadan alınan değer ve değerin birlikte yaratımı ve yıkımı kavramı ekseninde ortaya konması, bu davranışa sebep olan unsurların etkilerinin kıyaslanmasıdır. Bu amaç doğrultusunda bu davranışa öncül olacağı belirlenen kavramlar önceki çalışmalar dikkate alınarak belirlenmiştir. Fiziki mağazadan alışveriş yetkinliği, çevrimiçi mağazadan alışveriş yetkinliği, mağaza personeline olan güven, fiziki mağazadan algılanan değer, çevrimiçi mağazadan algılanan değer, mağazadan alınan değer ve değerin birlikte yaratılması ve yıkımı boyutları temelinde 40 ifade ile uygulamaya geçilmiştir. Araştırma verileri, çevrimiçi alışveriş yaptığını belirten 18 yaş üzeri tüketicilerden basılı form ve çevrimiçi form aracılığıyla elde edilmiştir. Türkiye'deki internet kullanımının yaşa göre dağılımına yakın bir kitleye kolayda örnekleme yöntemiyle ulaşılmış ve 989 adet anket toplanmıştır. Veriler açıklayıcı, doğrulayıcı faktör analizleri ve yapısal eşitlik modeli kullanılarak analiz edilmiştir. Çalışma ile fiziki mağazadan alışveriş yetkinliği ve fiziki mağazadan algılanan değerin mağazadan alınan değer üzerinde anlamlı ölçüde etkili olduğu, çevrimiçi mağazadan alışveriş yetkinliği, mağaza personeline olan güven, çevrimiçi mağazadan algılanan değer ve mağazadan alınan değer boyutlarının değerin birlikte yaratılması ve yıkımı boyutu üzerinde anlamlı ölçüde etkili olduğu sonucuna ulaşılmıştır.Consumers have begun to take advantage of information asymmetry with the diversification of access channels to information in recent years. Using these advantages for their own benefit maximization, consumers are cross-assessing their retail channels. This allows consumers to obtain products and services under the most favorable conditions. The behavior of researching instore and purchasing online, which is called showrooming, is one of the most important issues that need retail businesses' consideration. The aim of this study is to reveal the factors related to consumer and channel characteristics that affect the showrooming behavior in the context of instore value taking and the co-creation and co-destruction of the value, and comparing the effects of the factors causing this behavior. In line with this purpose, the concepts that are predicted to be antecedents to this behavior have been determined by considering previous studies. A survey consisted of 40 statements on the basis of the dimensions that are instore shopping savviness, online shopping savviness, trust in-store staff, perceived instore value, perceived online store value, instore value taking and co-creation and co-destruction of the value was implemented. Research data were obtained through printed and online forms from consumers over the age of 18 who stated that they shop online. A population that is close to the distribution of internet usage by age was reached via convenience sampling method and 989 surveys were collected in total. The data were analyzed using explanatory and confirmatory factor analysis and structural equation model. With the study, it was seen that in-store shopping savviness and perceived instore value have a significant effect on the instore value taking. It was also revealed that trust in-store staff, perceived online store value and instore value taking dimensions have a significant effect on co-creation and co-destruction of value dimensions

Роль бюрократии в демократизации Турции: период однопартийности и переход к многопартийной системе;The Role of Bureaucracy in Turkey’s Democratization Process: One-Party Period and Transition to Multi-Party System

Bu çalışmanın amacı demokratikleşme sürecinde bürokrasinin rolü, işlevi ve tutumunu incelemektir. Bu kapsamda Türkiye’de cumhuriyetin ilanından çok-partili hayata geçişe kadar demokratikleşme sürecinin incelendiği bu tarihsel araştırmada, bürokrasi ve demokrasi ilişkisi kuramsal olarak kısaca ele alındıktan sonra Türk siyasi hayatında önemli bir yeri olan bürokratik yönetim geleneğinin oluşumuna değinilmiştir. Daha sonra, tek-parti döneminde demokratikleşme sürecinde bürokrasinin rolü ve çok-partili hayata geçişle birlikte bu süreçte yaşanan değişim incelenmiştir. Sonuç olarak, bürokrasi ve demokrasi arasında bir ikilem bulunduğu, bürokrasinin demokratikleşme sürecini olumsuz yönde etkilediği, tek-parti döneminde bürokrasinin daha etkin olduğu, çok-partili hayata geçişle birlikte nispeten bürokrasinin gücünün azaldığı, ancak bürokratik vesayet geleneğinin günümüze kadar etkisini sürdürdüğü ve bu durumun demokratikleşme sürecine zarar verdiği görülmüştür.Цель данного исследования - изучить роль, функцию бюрократии_x000D_ в демократизации и ее отношение к этому процессу. В связи с этим_x000D_ в этом историческом исследовании, посвященном изучению про-_x000D_ цесса демократизации в Турции от провозглашения республики_x000D_ до перехода к многопартийной системе, с теоретической точки_x000D_ зрения кратко рассматриваются отношения между бюрократией_x000D_ и демократией. Вслед за этим исследовано формирование бюро-_x000D_ кратической традиции управления, занимающей важное место в_x000D_ политической жизни Турции, а также роль бюрократии в процессе_x000D_ демократизации в однопартийный период и изменения, которые_x000D_ произошли в этом процессе с переходом к многопартийной си-_x000D_ стеме. В заключении показано, что в турецком контексте наблю-_x000D_ дается дилемма между бюрократией и демократией, бюрократия_x000D_ негативно повлияла на процесс демократизации, она была более_x000D_ эффективной в однопартийный период, а власть бюрократии была_x000D_ относительно ослаблена с переходом к многопартийности. Тем не_x000D_ менее, традиция бюрократической опеки сохранилась до наших_x000D_ дней, и эта ситуация наносит ущерб процессу демократизации.;This study aims to scrutinize the role, function and the attitude of the bureaucracy_x000D_ in the process of democratization. In this context, this historical study_x000D_ examining the process of democratization in Turkey from the proclamation of_x000D_ the republic to the transition to a multiparty system briefly discusses the relationship_x000D_ between bureaucracy and democracy from a theoretical perspective._x000D_ Afterwards, the formation of a bureaucratic management tradition, which_x000D_ has an important place in Turkish political life, has been mentioned in this_x000D_ historical research, which has a significant place in Turkish political life, has_x000D_ been addressed.
