The capture, regeneration, and conversion of CO2 from ambient air and flue gas streams are critical aspects of mitigating global warming. Solid sorbents for CO2 absorption are very promising as they have high mass transfer areas without energy input and reduce emissions and minimize corrosion as compared to liquid sorbents. However, precisely tunable solid CO2 sorbents are difficult to produce. Here, we demonstrate the high-throughput production of hydrogel-based CO2-absorbing particles via liquid jetting. By wrapping a liquid jet consisting of an aqueous solution of cross-linkable branched polyethylenimine (PEI) with a layer of suspension containing hydrophobic silica nanoparticles, monodisperse droplets with a silica nanoparticle coating layer was formed in the air. A stable Pickering emulsion containing PEI droplets was obtained after these ejected droplets were collected in a heated oil bath. The droplets turn into mm-sized particles after thermal curing in the bath. The diameter, PEI content, and silica content of the particles were systematically varied, and their CO2 absorption was measured as a function of time. Steam regeneration of the particles enabled cyclic testing, revealing a CO2 absorption capacity of 6.5 +/- 0.5 mol kg(-1) solid PEI in pure CO2 environments and 0.7 +/- 0.3 mol kg(-1) solid PEI for direct air capture. Several thousands of particles were produced per second at a rate of around 0.5 kg per hour, with a single nozzle. This process can be further scaled by parallelization. The complete toolbox for the design, fabrication, testing, and regeneration of functional hydrogel particles provides a powerful route toward novel solid sorbents for regenerative CO2 capture.

Lithium-sulfur batteries are emerging as sustainable replacements for current lithium-ion batteries. The commercial viability of this novel type of battery is still under debate due to the extensive use of highly reactive lithium-metal anodes and the complex electrochemistry of the sulfur cathode. In this research, a novel sulfur-based battery has been proposed that eliminates the need for metallic lithium anodes and other critical raw materials like cobalt and graphite, replacing them with biomass-derived materials. This approach presents numerous benefits, encompassing ample availability, cost-effectiveness, safety, and environmental friendliness. In particular, two types of biochar-based anode electrodes (non-activated and activated biochar) derived from spent common ivy have been investigated as alternatives to metallic lithium. We compared their structural and electrochemical properties, both of which exhibited good compatibility with the typical electrolytes used in sulfur batteries. Surprisingly, while steam activation results in an increased specific surface area, the non-activated ivy biochar demonstrates better performance than the activated biochar, achieving a stable capacity of 400 mA h g(-1) at 0.1 A g(-1) and a long lifespan (>400 cycles at 0.5 A g-1). Our results demonstrate that the presence of heteroatoms, such as oxygen and nitrogen positively affects the capacity and cycling performance of the electrodes. This led to increased d-spacing in the graphitic layer, a strong interaction with the solid electrolyte interphase layer, and improved ion transportation. Finally, the non-activated biochar was successfully coupled with a sulfur cathode to fabricate lithium-metal-free sulfur batteries, delivering a specific energy density of similar to 600 Wh kg(-1).

The Impact of Health Information Technology on Hospital Performance: A Systematic Integrative Literature Review

引用

Health 2024年第4期16卷 257-279页

作者： Alisa Westerhof Cokky Hilhorst willem Jan Bos Accounting Auditing & Control Nyenrode Business University Breukelen Netherlands St. Antonius Ziekenhuis Utrecht Netherlands Department of Internal Medicine Nephrology Leiden University Medical Center Leiden Netherlands

Objective: To review, categorise, and synthesise findings from literature on health information technology (HIT) functionalities, HIT use, and the impact of HIT on hospital performance. Materials and Methods: We conducted a systematic integrative literature review based on a compre-hensive database search. To organise, categorise and synthesise the ex-isting literature, we adopted the affordance actualization theory. To align the literature with our research framework, we used four categories: 1) the functionalities of HIT and how these functionalities are measured;2) use and immediate outcomes of HIT functionalities;3) different perfor-mance indicators and how HIT functionalities affect them;and 4) what hospital characteristics influence the outcome of hospital performance. Results: Fifty-two studies were included. We identified four types of HIT. Only ten studies (19.2%) define the use of HIT by explicitly meas-uring the use rate of HIT. We identified five dimensions of hospital per-formance indicators. Every dimension showed mixed results;however, in general, HIT has a positive impact on mortality and patient readmis-sions. We found several hospital characteristics that may affect the rela-tionship between HIT and hospital-level outcomes. Discussion: Further efforts should focus on embedded research on HIT functionalities, use and effects of HIT implementations with more performance indicators and adjusted for hospital characteristics. Conclusion: The proposed framework could help hospitals and researchers make decisions regard-ing the functionalities, use and effects of HIT implementation in hospi-tals. Given our research outcomes, we suggest future research opportuni-ties to improve understanding of how HIT affects hospital performance. .

Bemisia tabaci is one of the most threatening pests in many crops. We sequenced part of the mitochondrial cytochrome oxidase I gene from fifty whitefly populations collected in Indonesia, Thailand, India and China. Nineteen unique sequences （haplotypes） of the cytochrome oxidase I were identified in these populations. They were combined with sequences available in databases, resulting in a total of 407 haplotypes and analyzed together with nine outgroup accessions. A phylogenetic tree was calculated using the maximum likelihood method. The tree showed that all groups that were found in previous studies were also present in our study. Additionally, seven new groups were identified based on the new haplotypes. Most B. tabaci haplotypes grouped based on their geographical origin. Two groups were found to have a worldwide distribution. Our results indicate that our knowledge on the species complex around B. tabaci is still far from complete.

Towards estimating computer users＇ mood from interaction behaviour with keyboard and mouse

引用

Frontiers of Computer Science 2013年第6期7卷 943-954页

作者： Iflikhar Ahmed KHAN willem-Paul BRINKMAN Robert HIERONS Department of Computer Software Engineering University of Engineering & Technology Mardan 23200 Pakistan Interactive Intelligence Group Delft University of Technology Delft 2628B the Netherlands Department of Information Systems and Computing Brunel University West London UB83PH UK

The purpose of this exploratory research was to study the relationship between the mood of computer users and their use of keyboard and mouse to examine the possibility of creating a generic or individualized mood measure. To examine this, a field study （n = 26） and a controlled study （n = 16） were conducted. In the field study, interaction data and self-reported mood measurements were collected during normal PC use over several days. In the controlled study, participants worked on a programming task while listening to high or low arousing background music. Besides subjective mood measurement, galvanic skin response （GSR） data was also collected. Results found no generic relationship between the interaction data and the mood data. However, the re- suits of the studies found significant average correlations be- tween mood measurement and personalized regression models based on keyboard and mouse interaction data. Together the results suggest that individualized mood prediction is pos- sible from interaction behaviour with keyboard and mouse.

Measuring the Competitiveness of China＇s Processed Exports

引用

China & World Economy 2015年第1期23卷 78-100页

作者： willem Thorbecke Research Institute of Economy Trade and Industry Tokyo Japan

China＇s surplus in processing trade remains large. Processed exports are final goods produced using parts and components that are imported duty free. Because much of the value-added of these exports comes from East Asia, exchange rates throughout the region should affect their foreign currency prices. This paper presents data on value-added exchange rates for processed exports over the 1993-2013 period and reports that they significantly affect exports. While the renminbi appreciated 36 percent between the beginning of 2005 and the end of2013, exchange rates in supply chain countries depreciated This has mitigated the effect of the RMB appreciation on the price competitiveness of processed exports.
