      Thermoelectric windows: A thermoelectric generator is embedded into a window glass that can generate 300 Watts of power at a temperature difference of 20 °C, achieving a new breakthrough in green building technology, as described in the Full Paper by Prof. Muhammad M. Hussain and colleagues at the King Abdullah University of Science and Technology on page 292. Forty percent of global energy consumption is related to room heating and cooling. Therefore, thermoelectric generators integrated into building materials can generate thermoelectricity based upon the temperature difference between the outside temperature and inside building temperature. One major challenge is to have a thermopile that is thick enough (at the least 5 mm in alignment with standard glass thickness). The micrometer-sized thermoelectric powders were therefore ball milled into nanostrucutured materials and then hot pressed into a mold to form 5 mm thermopiles before inserting into the window glass to make themorelectric windows.

    1. Overview of Design Issues in Product-Integrated Photovoltaics (pages 229–242)

      Georgia Apostolou and Prof. Angèle H. M. E. Reinders

      Photovoltaic products: Product-integrated PV (PIPV) is applicable to power ranges from several milliwatts, for PV chargers like the one which is indicated in the figure, up to hundreds of kilowatts for solar vehicles. It is expected that PIPV will be further developed in the forthcoming years and new PV products for both indoor and outdoor use will be released to the market, and here the current status is reviewed.

    1. Evidence of the Formation of Surface Palladium Carbide during the Catalytic Combustion of Lean Methane/Air Mixtures (pages 243–249)

      Adi Setiawan, Prof. Eric M. Kennedy, Prof. Bogdan Z. Dlugogorski, Prof. Adesoji A. Adesina, Olga Tkachenko and Prof. Michael Stockenhuber

      Version of Record online: 5 MAR 2014 | DOI: 10.1002/ente.201300119

      Lean on methane: The catalytic combustion of lean methane/air mixtures over palladium-based catalysts is investigated and the influence of operating parameters and pretreatment conditions on the activity and stability of the catalysts is studied. Significant differences were observed in the light-off temperatures and extent of coke deposition, depending on whether the catalysts were conditioned under oxidizing or reducing conditions.

    2. Application of Three-Vapor Recompression Heat-Pump Concepts to a Dimethylformamide–Water Distillation Column for Energy Savings (pages 250–256)

      Xiaoxin Gao, Prof. Zhengfei Ma, Jiangquan Ma and Limin Yang

      Version of Record online: 3 MAR 2014 | DOI: 10.1002/ente.201300141

      Compressive results: An N,N-dimethylformamide (DMF)/water mixture is selected to analyze several distillation-assisted mechanical vapor-recompression (MVR) heat-pump processes compared to conventional distillation. Four distillation process designs are simulated by using the Aspen software platform to determine the energy savings and best alternative.

    3. Hybrid Composites of LiMn2O4–Graphene as Rechargeable Electrodes in Energy Storage Devices (pages 257–262)

      Composite results: This paper details the synthesis of spinel-lithium manganese oxide (LiMn2O4) powders by using a simple sol–gel method with polyvinyl alcohol (PVA), and further combination with a conductive additive, graphene, to produce a composite electrode material for simultaneously improving power density (current Li-ion batteries have low power density as a disadvantage) along with energy density.

    4. A Sustainable Preparation of Glycerol Carbonate from Glycerol and Urea Catalyzed by Hydrotalcite-Like Solid Catalysts (pages 263–268)

      Yongfa Sun, Dr. Xinli Tong, Zhidong Wu, Jinbiao Liu, Yongtao Yan and Song Xue

      Selective synthesis: The selective synthesis of glycerol carbonate from glycerol and urea catalyzed by hydrotalcite-like compounds is performed under solvent-free conditions, and that such compounds including Mg, Zn, and Al elements have very high catalytic activity. As a result, high conversion and selectivity for glycerol carbonate are obtained under suitable conditions.

    5. Polymer Solar Cells Processed Using Anisole as a Relatively Nontoxic Solvent (pages 269–274)

      Swaminathan Venkatesan, Dr. Qiliang Chen, Evan C. Ngo, Nirmal Adhikari, Kelly Nelson, Ashish Dubey, Jianyuan Sun, Prof. Venkateswara Bommisetty, Prof. Cheng Zhang, Prof. David Galipeau and Prof. Qiquan Qiao

      Detoxifying photovoltaics: A relatively nontoxic single solvent, anisole, was successfully demonstrated to process organic photovoltaics, thereby decreasing the risk to human health for large-scale production. The photo-charge extraction by linearly increasing voltage (photo-CELIV) and transient photocurrent/photovoltage measurements were used to characterize the devices.

    6. Large-Scale Separators Based on Blends of Aromatic Polyethers with PEO for Li-Ion Batteries: Improving Thermal Shrinkage and Wettability Behavior (pages 275–283)

      Dr. Valadoula Deimede, Dr. Andrea Voege, Dr. Georgia Lainioti, Dr. Costas Elmasides and Prof. Joannis K. Kallitsis

      Version of Record online: 3 MAR 2014 | DOI: 10.1002/ente.201300153

      Large-scale separators: The development of large-scale separators with tuned microstructures is presented for application to Li-ion batteries. Porous separators based on blends of aromatic polyethers and polyethylene oxide (PEO) are obtained, showing much improved thermal shrinkage and wettability behavior compared to the commercial separator.

    7. Comparison of Structure and Gasification Reactivity of Rapid Pyrolysis Chars of Coal Water Slurries and Parent Coals (pages 284–291)

      Zhijie Zhou, Lu Ding, Lei Wu, Shanjun Lin, Tongmin Cui, Prof. Guangsuo Yu and Prof. Fuchen Wang

      Version of Record online: 3 MAR 2014 | DOI: 10.1002/ente.201300172

      Coal hard results: Rapid pyrolysis of coal–water slurries (CWs) and parent coals are performed in a drop-style high-frequency furnace. The results show that, as the pyrolysis temperature increases, the char pyrolysis yields differ between CWS and parent coals, in which there is a competition between steam reaction with coal/char and water evaporation in the process.

    8. Manufacturing of Thermoelectric Nanomaterials (Bi0.4Sb1.6Te3/Bi1.75Te3.25) and Integration into Window Glasses for Thermoelectricity Generation (pages 292–299)

      Dr. Salman B. Inayat, Kelly R. Rader and Prof. Muhammad M. Hussain

      Version of Record online: 26 FEB 2014 | DOI: 10.1002/ente.201300166

      More than a window: Until now thermoelectric generators have been built on a single side of a substrate, therefore requiring the two temperature environments to exist on the same side of the substrate. Here, thermoelectric nanomaterials are embedded into window glass to generate thermoelectricity from the temperature gradient between the solar-heated outdoors and the relatively cold indoor temperature.
