Exploiting In-Situ NMR to Monitor the Formation of a Metal-Organic Framework

Jones, Corey; Hughes, Colan; Yeung, Hamish; Paul, Alison; Harris, Kenneth D. M.; Easun, Timothy

The formation processes of metal-organic frameworks are increasingly widely researched using in-situ techniques, although there remains a scarcity of NMR studies in the field. In this work, the synthesis of MFM-500(Ni) has been investigated using the Combined Liquid- And Solid-State In?situ Crystallization NMR strategy, which provides information on the time-evolution…

Effect of Phosphaphenanthrene Skeleton in Sulfonated Polyimides for Proton Exchange Membrane Application

Mandal, Arun Kumar; Bisoi, Soumendu; Banerjee, Susanta

Sulfonic acid groups containing aromatic polyimides are of great interest as polymer electrolyte membranes owing to their high thermal and mechanical stability, strong resistance to fuel crossover, excellent film-forming ability, and high proton conductivity. However, these polymers generally experience reduced oxidative permanence. To alleviate the problems associated with the oxidative…

Random Organic Nanolaser Arrays for Cryptographic Primitives

Feng, Jiangang; Wen, Wen; Wei, Xiao; Jiang, Xiangyu; Cao, Moyuan; Wang, Xuedong; Zhang, Xiqi; Jiang, Lei; Wu, Yuchen

Next-generation high-security cryptography and communication call for nondeterministic generation and efficient authentication of unclonable bit sequences. Physical unclonable functions using inherent randomness in material and device fabrication process have emerged as promising candidates for realizing one-way cryptographic systems that avoid duplication and attacks. However, previous…

Stabilizing Silver Window Electrodes for Organic Photovoltaics Using a Mercaptosilane Monolayer

Lee, Jaemin; Walker, Marc; Varagnolo, Silvia; Huband, Steven; Hatton, Ross A.

A single layer of the bifunctional molecule 3-mercaptopropyltrimethoxysilane is shown to be remarkably effective at improving the stability of optically thin silver film electrodes toward spontaneous morphological change and oxidation by airborne sulfur. Inclusion of this layer in the novel transparent electrode WO3(30 nm)/silver (13 nm)/sol–gel ZnO (27 nm) at…

Physical Chemical Properties of Shea/Cocoa Butter Blends and their Potential for Chocolate Manufacture

Rodriguez-Negrette, Ana Carolina; Huck-Iriart, Cristián; Herrera, María Lidia

Cocoa butter (CB) is the preferred fat for chocolates and confections. However, for technological and economic reasons, there have been strong efforts for partially replacing it. As shea butter (SB) has become an important natural source of symmetrical stearic-rich triacylglycerols (TAG), the aim of this work was to study physical…

Collective orientational order and phase behavior of a discotic liquid crystal under nanoscale confinement

Yildirim, Arda; Sentker, Kathrin; Smales, Glen Jacob; Pauw, Brian Richard; Huber, Patrick; Schönhals, Andreas

The phase behavior and molecular ordering of hexakishexyloxy triphenylene (HAT6) DLCs under cylindrical nanoconfinement are studied utilizing differential scanning calorimetry (DSC) and dielectric spectroscopy (DS), where cylindrical nanoconfinement is established through embedding HAT6 into the nanopores of anodic aluminum oxide (AAO) membranes, and a silica membrane with pore diameters ranging
