Paired Copper Monomers in Zeolite Omega: The Active Site for Methane‐to‐Methanol Conversion

Amy J. Knorpp, Ana B. Pinar, Christian Baerlocher, Lynne B. McCusker, more

Angewandte Chemie > 133 > 11 > 5918 - 5922

The direct conversion of methane to methanol using oxygen is a challenging but potentially rewarding pathway towards utilizing methane. By using a stepwise chemical looping approach, copper‐exchanged zeolites can convert methane to methanol, but productivity is still too low for viable implementation. However, if the nature of the active site could be elucidated, that information could be used to...

Frontispiece: Characterization at the Level of Individual Crystals: Single‐Crystal MFI Type Zeolite Grains

Tim Gruene, Teng Li, Eric van Genderen, Ana B. Pinar, more

Chemistry – A European Journal > 24 > 10 > n/a - n/a

Zeolites form an important class of catalysts, for example, zeolite ZSM‐5 finds widespread application in refinery and industry. They build a porous material inwrought with channels and provide a large surface to the catalytic guest reaction. Current research results indicate the presence of a certain type of intergrowth that would interfere with the channel system. However, industrially‐used zeolite...

Characterization at the Level of Individual Crystals: Single‐Crystal MFI Type Zeolite Grains

Tim Gruene, Teng Li, Eric van Genderen, Ana B. Pinar, more

Chemistry – A European Journal > 24 > 10 > 2384 - 2388

Electron‐diffraction data on the zeolites Silicalite‐1 and ZSM‐5 (both MFI framework type) were collected from individual grains of about 150×100×50 nm³. Crystals were synthesized with tetrapropylammonium as structure‐directing agent. The resolution extended to about 0.8 Å for Silicalite‐1 and about 0.9–1.0 Å for ZSM‐5 crystals. Analysis of several data sets showed that at the nanometre‐scale, these...

First reported treatment of aggressive hemangioma with intraoperative radiation therapy and kyphoplasty (Kypho-IORT)

B. Pinar Sedeño, N. Rodríguez Ibarria, H. Mhaidli Hamdani, T. Fernández Varela, more

Clinical and Translational Radiation Oncology > 2017 > 2 > C > 19-22

Aggressive hemangiomas invade the spinal canal and/or paravertebral space and may cause cord compression and neurological symptoms. Radiation therapy was recognized as an effective strategy for the treatment of aggressive hemangiomas. Here, it is reported the first case of aggressive vertebral hemangioma treated by a combination of intraoperative radiation therapy and kyphoplasty (Kypho-IORT).

H-ZSM-5 zeolite model crystals: Structure-diffusion-activity relationship in methanol-to-olefins catalysis

Pit Losch, Ana B. Pinar, Marc G. Willinger, Karel Soukup, more

Journal of Catalysis > 2017 > 345 > C > 11-23

Large ZSM-5 zeolite crystals synthesized in fluoride medium show an astonishing activity, stability as well as selectivity towards light olefins in the Methanol-To-Olefins (MTO) reaction. By proper control of the synthesis parameters, ZSM-5 single crystals of unprecedented high quality are produced. The absence of usually uncontrollable variables such as structural defects, external non selective...

Building a “Modern” and “Western” image: Miss Turkey beauty contests from 1929 to 1933

B. Pınar Özdemir

Public Relations Review > 2016 > 42 > 5 > 759-765

This article focuses on the beauty contests organised by the Cumhuriyet (Republic) newspaper in late 1920s and early 1930s in Turkey with the aim of publicizing the young Turkish Republic. The research employs those issues of Cumhuriyet newspaper published between 1929 and 1933 in order to demonstrate the newspaper’s motivation for the international publicity. This study argues that the beauty contests...

Synthesis of ferrierite by a new combination of co-structure-directing agents: 1,6-bis(N-methylpyrrolidinium)hexane and tetramethylammonium

Ramon K.S. Almeida, Luis Gómez-Hortigüela, Ana B. Pinar, Joaquín Peréz-Pariente

Microporous and Mesoporous Materials > 2016 > 232 > C > 218-226

Ferrierite zeolite was synthesized in fluoride medium using dicationic 1,6-bis(N-methylpyrrolidinium)hexane (MPH) as a bulky structure directing agent (SDA) in combination with tetramethylammonium (TMA) as a small co-structure-directing agent (co-SDA). When trimethylamine, pyrrole or tert-butylamine were used as co-SDA, amorphous and beta zeolite (BEA framework type) were obtained, suggesting that...

The effect of water on the mechanical properties of soluble and insoluble ceramic cements

Ilsoo Koh, Alejandro López, Ana B. Pinar, Benedikt Helgason, more

Journal of the Mechanical Behavior of Biomedical Materials > 2015 > 51 > Complete > 50-60

Ceramic cements are good candidates for the stabilization of fractured bone due to their potential ease of application and biological advantages. New formulations of ceramic cements have been tested for their mechanical properties, including strength, stiffness, toughness and durability. The changes in the mechanical properties of a soluble cement (calcium sulfate) upon water-saturation (saturation)...

Aluminum Redistribution during the Preparation of Hierarchical Zeolites by Desilication

Sharon Mitchell, Maria Milina, René Verel, Manuel Hernández‐Rodríguez, more

Chemistry – A European Journal > 21 > 40 > 14156 - 14164

A literature survey reveals a prominent reduction in the concentration of Brønsted acid sites in hierarchically organized zeolites with increasing mesoporous or external surface area independent of the framework type or synthesis route; this suggests a common fundamental explanation. To determine the cause, nature, and impact of the underlying changes in aluminum speciation, this study combines a...

Zeolites with Continuously Tuneable Porosity

Paul S. Wheatley, Pavla Chlubná‐Eliášová, Heather Greer, Wuzong Zhou, more

Angewandte Chemie > 126 > 48 > 13426 - 13430

Zeolites are important materials whose utility in industry depends on the nature of their porous structure. Control over microporosity is therefore a vitally important target. Unfortunately, traditional methods for controlling porosity, in particular the use of organic structure‐directing agents, are relatively coarse and provide almost no opportunity to tune the porosity as required. Here we show...

G. Senem Gençtürk Hızal, B. Pınar Özdemir, Melike Aktaş Yamanoğlu

Public Relations Review > 2014 > 40 > 4 > 632-638

This study is based on a historical research, which focuses on the institutionalization of public relations in Turkey during the 1960s, and interprets this process in the frame of planned development discourse. Primary written sources collected from archive research and oral narratives generated from fourteen semi-structured interviews conducted with the pioneers in Turkey are analyzed through categorization...

The Assembly‐Disassembly‐Organization‐Reassembly Mechanism for 3D‐2D‐3D Transformation of Germanosilicate IWW Zeolite

Pavla Chlubná‐Eliášová, Yuyang Tian, Ana B. Pinar, Martin Kubů, more

Angewandte Chemie > 126 > 27 > 7168 - 7172

Hydrolysis of germanosilicate zeolites with the IWW structure shows two different outcomes depending on the composition of the starting materials. Ge‐rich IWW (Si/Ge=3.1) is disassembled into a layered material (IPC‐5P), which can be reassembled into an almost pure silica IWW on treatment with diethoxydimethylsilane. Ge‐poor IWW (Si/Ge=6.4) is not completely disassembled on hydrolysis, but retains...
