title: Non-Destructive Thickness Mapping Of Wafer-Scale Hexagonal Boron Nitride Down To A Monolayer

description: Raw data associated with the publication "Non-Destructive Thickness Mapping of Wafer-Scale Hexagonal Boron Nitride<br>
Down to a Monolayer" published in ACS Applied Materials & Interfaces under the DOI: 10.1021/acsami.8b08609
description: ABSTRACT
The availability of an accurate, non-destructive method for measuring thickness and continuity of 2D materials with monolayer sensitivity over large areas is of pivotal importance for the development of new applications based on two-dimensional (2D) materials. While simple optical contrast methods and electrical measurements are sufficient for the case of metallic and semiconducting 2D materials, the low optical contrast and high electrical resistivity of wide band gap dielectric 2D materials such as hexagonal boron nitride (hBN) hampers their characterization. In this work, we demonstrate a non-destructive method to quantitatively map the thickness and continuity of hBN monolayers and bilayers over large areas. The proposed method is based on acquisition and subsequent fitting of ellipsometry spectra of hBN on Si/SiO2 substrates. Once a proper optical model is developed, it becomes possible to identify and map the commonly observed polymer residuals from the transfer process and obtain sub-monolayer thickness sensitivity for the hBN film. With some assumptions on the optical functions of hBN, the thickness of an as-transferred hBN monolayer on SiO2 is measured as 4.1 Å ± 0.1 Å, whereas the thickness of an air-annealed hBN monolayer on SiO2 is measured as 2.5 Å ± 0.1 Å. We argue that the difference in the two measured values is due to the presence of a water layer trapped between the SiO2 surface and the hBN layer in the latter case. The procedure can be fully automated to wafer-scale and extended to other 2D materials transferred onto any polished substrate, as long as their optical functions are approximately known.

title: Data from: Landscape context is more important than wetland buffers for farmland amphibians.

description: Abstract of associated article: In regions with high rates of wetland loss, remnant wetlands and constructed ponds can provide important breeding habitat for amphibians. However, such wetlands are often embedded in a matrix of agricultural fields, potentially putting species within these wetlands at risk. One recommendation for conservation of amphibians in agriculture-dominated landscapes is to maintain a buffer of permanent vegetation around the wetland. However, it is not clear how wide wetland buffers must be to effectively conserve amphibians in agriculture-dominated landscapes or what vegetation types are suitable buffer vegetation. Furthermore, it is not clear whether wetland buffers produce similar—or better—conservation outcomes for amphibians than actions conducted at larger spatial extents. We addressed these questions using data from anuran (frog and toad) breeding call surveys in 36 wetlands in rural eastern Ontario, Canada. First, we tested for the effects of 49 different wetland buffer measurements on anuran richness, relative anuran abundance, and the abundance/probability of occurrence of individual species. These 49 measurements represented all combinations of seven different ways to measure the wetland buffer size and seven types of buffer vegetation. Wetland buffer size was measured as the minimum width of buffer vegetation contiguous with the wetland and proportion of the area within 5, 16, 30, 50, 120, or 300m of the wetland containing buffer vegetation that was contiguous with the wetland. Then, to compare the strength of effect of wetland buffers versus landscape context on anurans, we compared the wetland buffer measurement with the strongest positive effect on each anuran response (from the previous analysis) to the effects of three landscape-scale variables: area of woodland; area of wetlands, streams, rivers, and lakes; and road density. We did not detect positive effects of wetland buffers on anuran richness or relative anuran abundance. This is because positive effects of wetland buffers on individual species were rare, i.e. positive effects were only supported for two of the six species with enough data to model individually: American toads (Anaxyrus americanus) and green frogs (Lithobates clamitans). Furthermore, we found that the landscape context had much stronger effects on relative anuran abundance than the wetland buffer, with effect sizes ranging from 4 (road density) to 14 (woodland cover) times that of the wetland buffer. These findings suggest that guidelines for anuran conservation in agricultural landscapes should generally focus on protection of terrestrial habitat at the landscape scale rather than on maintenance of wetland buffers.

title: Data for: Insights into the enhanced CO2 photocatalytic reduction performance over hollow-structured Bi decorated g-C3N4 nanohybrids under visible-light irradiation

description: hollow-structured Bi decorated g-C3N4 hybrids were successfully fabricated by a simple solvothermal method and applied for the first time to the photocatalytic reduction of CO2. Remarkably, the composites exhibited excellent CO2 conversion efficiencies in the presence of H2O under visible light irradiation compared to unmodified g-C3N4, especially for the production of CH4. The optimum photocatalyst 30-Bi/g-C3N4 presented the best production of CO and CH4, approximately 3 times and 9 times as high as those of unmodified g-C3N4, respectively. A series of characterizations were conducted to explore the essence behind such an enhancement; we found that enhanced light harvesting, quick separation of photoinduced carriers and more negative conduction band, due to the formation of a Schottky junction between g-C3N4 and Bi metal and the solvothermal process, co-contributed for the enhanced CO2 conversion; A more important finding was that the surprising improvement of CH4 yield stem primarily from the introduction of the hollow-structured Bi, which enabled the accumulation of electrons on its surface exhibiting the metal-like property. The CO2 photocatalytic conversion process was also investigated by in-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFT) spectroscopy and we found that HCO3- and CO2- were active intermediates over 30-Bi/g-C3N4 and Bi doping could promote the activation of CO2. In summary, this work presented hollow-structured Bi decorated g-C3N4 composites as new materials for energy applications, proving once more the meta-like nature of bismuth, and laying the groundwork for the utilization of Bi in CO2 photocatalytic reduction processes.

title: Analysis and comparison of pumping concrete plug in tunnel no. 10 and no. 12 in longkou power station

description: The concrete of the first phase of water resources of Longkaikou hydropower station is used as the research object. The pipe diameter selection of the pump pipe, the design scheme of the mixture ratio and the prevention of plugging pipe of the pump are summarized. In this paper, different research and comparison are conducted on the proportioning design of the super-long pumping distance of the pump distance less than 800m and the length of the tunnel with no. 12 tunnel, which is longer than 800m. The matching ratio of the super-long distance pump concrete obtained by the 12 tunnel is of great reference value for similar pumping construction in the future.

title: Energy evaluation of the mechanical subcooling impact on a CO2 DX-system in a commercial MT cabinet.

description: Recent experimental studies of the use of the mechanical subcooling in CO2 plants have demonstrated the improvements in COP and Capacity that can be achieved. Improving the energy aspects in warm countries is important in order to equate these systems to the classical ones. The aim of this study is to analyse in an experimental way the effect of this system applied to a commercial medium temperature (MT) cabinet using direct expansion. This work measures the energy consumption of a direct expansion (DX) system using a CO2 cycle with dedicated mechanical subcooling with respect to a classic CO2 cycle, without mechanical subcooling. The laboratory environmental conditions for the cabinet were 25ºC and relative humidity of 55% and the experimental tests performed with both DX-systems have been carried out at six heat rejection temperatures (17.9, 23.6, 28.0, 32.7, 38.2 and 43.6ºC), providing the cooling needs to the medium temperature cabinet for fresh product (2 °C). The analysis and comparison of these experimental data are presented and discussed in this work.

title: Experimental assessment of a sorption storage for integration in industrial processes.

description: Thermal energy storage systems are becoming central components of several processes, due to the requests for high efficiency in the residential, industrial and mobility fields. Among the various technologies available for thermal storage, thermochemical storage with sorption materials presents some interesting features for the application in the industrial field: theoretically infinite storage time, possibility of recovering waste heat for the supply of cold to the user, high energy density if compared to sensible and latent heat storage. In this work an innovative sorption cold/heat storage, employing water (R718) as a refrigerant, and the experimental activity for its assessment is presented. The experimental set-up used consists of a vacuum chamber, in which is possible to install different sorption reactors, and an evaporator/condenser. This device is connected to a testing bench that allows managing and measuring energy flows and the temperature levels for charging and discharging phases. The application of the storage under different operating conditions and the effect of such parameters on its performance were evaluated.

title: A field survey of ammonia-water absorption heat pump performance.

description: A school building located on the mountains in the North-East of Italy is equipped with ammonia water absorption heat pumps both for room heating and for heating the ventilation air. Whereas the formerresort to vertical ground boreholes and solar collectors as cold source, the heat pumps of the ventilation section use the ground or as well the heat recovery from the exhausted air. The plant was carefully monitored and the following energy flows were logged hourly, via thermal energy meters, together with inlet and outlet temperatures: - condenser/absorber and evaporator of each heat pump; -ground circuits, separately for ventilation and space heating. The long term survey during a period of more than 4 years allows to experimentally evaluate in real operation the absorption heat pumps performance for different temperatures of the cold source, as the inlet temperature extended from few degrees when the source is the ground to even more than 20 °C when the source is from the solar collectors. Moreover it is possible to estimate the eventual equipment decay of performance during the considered period.

title: Design and simulations of refrigerated sea water chillers with CO2 ejector pumps for marine applications in hot climates.

description: Various system configurations and control strategies were developed in order to improve performance of R744 systems in hot ambient conditions. However, stationary land applications are characterised by negligible limits of space for system equipment as in the case of marine industry, i.e. fishing vessels. CO2 refrigeration system for fishing vessels are developed by Kuldeteknisk AS. Namely, Refrigerated Sea Water Chillers operation at Norwegian coast confirmed successful application of this approach. In this study, modified layouts are evaluated for operation in warmer climates without the need for an additional compressor unit, to maintain the compactness of the unit. The flash gas valve-, parallel compression- and multi-ejector system was numerically investigated. Moreover, each system was equipped in the liquid ejector section enabling a flooded operation of the evaporator. Sea water temperatures as occurring in Mediterranean and East-Asian waters were investigated. Both the optimal high-pressure as well as the pressure level in an intermediate pressure receiver are controlled to achieve low energy consumptions. Finally, up to 70% of performance improvement was obtained in the case of the most advanced installation working in warm East-Asian waters. The obtained results showed that the proper design of the system should ensure no necessity of an additional compressor in warmer climates still maintaining the designed cooling capacity.

title: A review on recent technological advancements in multi-ejector concept.

description: As a consequence of the coming into force of the EU F-Gas Regulation 517/2014, enormous technological developments have been experienced on the part of transcritical R744 supermarket refrigeration systems. These have led to the wide acceptance of multi-ejector based technologies as the most promising hydrofluorocarbon (HFC)-free solutions for commercial refrigeration sector. Approximately 50 stores have been equipped with a multi-ejector block. Furthermore, such an expedient is expected to offer significant electricity savings in other energy-demanding applications (e.g. hotels, gyms) as well, even in warm climates. This work summarizes the evolution of R744 multi-ejector enhanced parallel compression system architectures for supermarket applications. Additionally, their technological aspects as well as the potential energy benefits along with some relevant field/experimental measurements are also presented. Furthermore, the experience gained in the use of the multi-ejector concept in transcritical R744 heat pump technologies is summed up. At last, the persistent challenges needing to be faced are revealed.

title: Integrated heating and cooling CO2 heat pump system in a modern distribution centre.

description: Industry is responsible for about 25-30 % of the global primary energy demand (Elmegaard, Zühlsdorf et al. 2017), and around two thirds of this is used for heating and cooling (Elmegaard, Zühlsdorf et al. 2017). Several recent innovations can improve the thermal energy efficiency and enable smart utilization of sun and/or surplus heat in several plants, yet they are not well-known and therefore rarely used. Novel approaches for supplying heating and cooling by integrated CO2 heat pump systems are presented; including: direct heat exchange with CO2, multiejectors, solutions to avoid implosion in CO2 refrigeration systems at low ambient temperature, integration with high temperature heat pumps (above 100°C), ground condensers and optimal insulation. Some of these technologies are implemented, some are under construction and others still remain at concept level.

title: Energy efficient professional counter cabinet.

description: A Danish manufacturer of professional food service cabinets is involved in an R&D project with the aim of developing a new generation of professional food service refrigerated counters. The project also involves Danish Technological Institute (DTI), the Technical University of Denmark (DTU), a global manufacturer of compressors and a global manufacturer of fans. The aim of the project is to reach energy class “A” of the EU energy labelling scheme for professional service cabinets. The present generation of cabinets is classified in energy class “C”. Thus, it requires a reduction of almost 50% energy consumption to reach energy class “A”. The testing is carried out according to EN16825. During the project, it became clear that the goal can be reached by reducing the “cold bridges” around the doors, by increasing the insulation thickness, and improving the refrigeration system by using a new compressor technology as well as a better condenser fan motor. R290 is used as the refrigerant.

title: Numerical analysis and optimization of CO2 vapor injection heat pump cycle with two phase ejector.

description: Refrigeration and air conditioning industry is influenced by environmental issues such as global warming and air pollution. Therefore, new refrigerants for solving and preventing global warming problem are strongly required. In this reason, natural refrigerants are getting attention again. Among many natural refrigerants, carbon dioxide has a lot of advantages as a refrigerant. However, simple CO2 heat pump cycle has low COP compared to that of other cycles with commercial refrigerants. In this study, to enhance the performance of heat pump system using CO2 refrigerant, a novel vapor injection cycle equipped with an ejector is proposed and its performance is analyzed. By using an ejector to feed extra refrigerant into vapor injection line, the cycle can utilize expansion energy of refrigerant and reduce compression work. The performance of this cycle can be changed by many cycle characteristic variables. The injection pressure and the mass flow rate are the major parameters which influence the performance of vapor injection cycle. Ejector performance and the mass flow rate ratio of the primary and secondary flows can also be main parameters of this cycle. The effect of these parameters on the target cycle performance is investigated. From these results, optimization of this cycle is conducted.

title: Experimental study on a cascade chiller for air conditioning applications.

description: Cascade chillers realised through a connection of a thermally driven chiller and a vapour compression one allow exploiting the favourable features of both systems. In the present work, the experimental characterization of such a cascade is presented. It was performed by means of a testing rig suitable for the testing of thermally driven systems and the effect of operating conditions on the performance of the cascade was evaluated. The savings due to the operation of the cascade were calculated and the reduction in electric consumption with respect of the vapour compression system only were estimated in up to 40%. Moreover, a basic thermodynamic model was developed to evaluate different natural refrigerants. The theoretical study revealed that a performance up to 110% higher with respect to traditional chillers could be obtained if the cascade was used in refrigeration applications with R290 as refrigerant.
