Energetic Analysis and Working Fluids Selection for a New Power and Refrigeration Combined Ecological System

The main purpose of this study is to analyze the performance of a new system that combines organic Rankine Cycle (ORC) and vapor compression refrigeration cycle (VCRC) for refrigeration and cogeneration.This system uses low-temperature heat sources such as solar energy,geothermal,industrial waste heat and biomass.The novelty of the proposed system manifests itself essentially in:the development of new ORC-VCRC combination architecture,lowering the ORC condensing temperature,the possibility of refrigeration production by the ORC upstream of the pumping phase,preheating of ORC using VCRC fluid and new configurations based on the integration of heat recovery systems to improve the overall system performance.The first part of this study presents the energetic analysis for the basic system using different working fluids and investigation of the operating parameters effect on the system performance (The system performance is described by the ORC thermal efficiency,the VCRC coefficient of performance and the system overall efficiency).Ten working fluids have been selected in order to provide the most adequate candidates for the proposed system.The results showed that the heating temperature and the cooling temperature have a significant effect on the system performance.The choice of fluid was also mentioned;the obtained results confirmed that the best combination for the basic system is R236fa-acetone.Four system configurations are developed and analyzed in the second part of the study.Also in the same part of the study,we will compare these configurations in terms of the performance rate retained.In the last part,we will make a comparison of this new system with another system.
Application of PCM-based Thermal Energy Storage System in Buildings:A State of the Art Review on the Mathematical Modeling Approaches and Experimental Investigations

This review paper critically analyzes the most recent literature (64% published after 2015) on the experimentation and mathematical modeling of latent heat thermal energy storage (LHTES) systems in buildings.Commercial software and in-built codes used for mathematical modeling of LHTES systems are consolidated and reviewed to provide details on the selection of appropriate tools.Insights on software's computing speed,model simplicity,accuracy (by considering the convective term in the melting process),and application of artificial neural networks are reviewed in detail.Moreover,the overall research status of the experiments conducted on the phase change material-based LHTES systems with different experiment configurations is reviewed.The analysis shows that ANSYS Fluent is the most widely used software for specific heat transfer phenomenon in storage tanks,while self-developed models with simplified terms are evaluated as more flexible and easier to apply.For hybrid systems,self-developed MATLAB,mature parts in ESP-r,TRNSYS,and EnergyPlus are compatible.Further,most of the experimental investigations are conducted on the laboratory scale,providing data for model validation.To provide a clear guidance for the future market application,the scope for future works is presented.With this review,it would be easier to develop a unified,simplified,visual,and accurate simulation platform for the PCM-based thermal energy storage in buildings.
Soil texture affects the conversion factor of electrical conductivity from 1:5 soil-water to saturated paste extracts

Electrical conductivity (EC) of soil-water extracts is commonly used to assess soil salinity.However,its conversion to the EC of saturated soil paste extracts (ECe),the standard measure of soil salinity,is currently required for practical applications.Although many regression models can be used to obtain ECe from the EC of soil-water extracts,the application of a site-specific model to different sites is not straightforward due to confounding soil factors such as soil texture.This study was conducted to develop a universal regression model to estimate a conversion factor (CF) for predicting ECe from EC of soil-water extracts at a 1:5 ratio (EC_(1:5)),by employing a site-specific soil texture (i.e.,sand content).A regression model,CF = 8.910 5e~(0.010 6sand)/1.298 4 (r~2 = 0.97,P <0.001),was developed based on the results of coastal saline soil surveys (n = 173) and laboratory experiments using artificial saline soils with different textures (n = 6,sand content = 10%-65%) and salinity levels (n = 7,salinity = 1-24 dS m~(-1)).Model performance was validated using an independent dataset and demonstrated that ECe prediction using the developed model is more suitable for highly saline soils than for low saline soils.The feasibility of the regression model should be tested at other sites.Other soil factors affecting EC conversion factor also need to be explored to revise and improve the model through further studies.
Nitrogen slow-release behavior of oxamide granules in two different types of paddy soils

Oxamide is a potential slow-release nitrogen (N) fertilizer,especially under waterlogged conditions,due to its low solubility in water and the slow-release of ammonium by soil amidases.To investigate the effects of oxamide granules (2.00-2.38 mm in diameter) as a single basal fertilizer (180 or 144 kg N ha~(-1)) on rice growth,soil properties,and N use efficiency in terms of N recovery efficiency (NRE),we conducted field experiments on two different types of paddy soils over two rice-growing seasons.Results showed that the fertilization effects of oxamide granules varied between the two types of paddy soils.In the red clayey paddy soil,the grain yields for both rice-growing seasons were high with a significantly higher NRE in the oxamide treatment than in the urea treatment.However,in the alluvial sandy paddy soil,the grain yields in the oxamide treatment were slightly lower than those in the urea treatment.Furthermore,oxamide produced little improvement in NRE in the alluvial sandy paddy soil.Soil incubation experiments over 98 d were also carried out to evaluate the factors affecting the N release behavior of oxamide granules in the two types of paddy soils.We found that the amidase activity was higher and,therefore,the oxamide hydrolysis rate was faster in the alluvial sandy paddy soil,which had a higher soil pH value and organic matter content,compared to the red clayey paddy soil.The faster N release and the longer growth period resulted in a mismatch between N supply by oxamide and rice demand,which,in turn,led to little improvement in NRE and a decreased grain yield in the alluvial sandy paddy soil,especially in the reduced oxamide treatment.These results could help select the appropriate size of oxamide granules for use as a slow-release N fertilizer depending on the soil properties and growth period of rice.
Effective alleviation of Cd stress to microbial communities in mining reclamation soils by thiourea-modified biochar amendment

Reclaimed soils in mining area usually display low fertility and present Cd stress.The amendment of modified biochar effectively fixes Cd in soils,enhances soil fertility,and reduces Cd stress in soil microorganisms.However,the effect of thiourea-modified biochar (TBC) on microbial adaptability to Cd stress in mining reclamation soils is still unclear.The present work studied the Cd immobilization and microbial community changes in a mining reclamation soil displaying extreme Cd contamination under TBC amendment.The results indicated that the amendment of TBC significantly enhanced (P <0.05) soil pH,the content of available phosphorus (AP),and the activities of urease and polyphenol oxidase by 1.3%,463.4%,54.4%,and 84.0%,respectively,compared to the control without amendment.The amount of toxicity characteristic leaching procedure-extracable Cd decreased (P <0.05) by 68.0% in the TBC-amended soil compared with the unamended soil.The structure of soil microbiota was reorganized and the alpha diversity index was increased in the TBC treatment.The TBC amendment increased the relative abundances of Proteobacteria,Bacteroidota,and Zoopagomycota,which were strongly associated (P <0.01) with higher soil pH and AP.Structural equation model results demonstrated that Cd immobilization was directly influenced by soil pH,AP,and urease,and indirectly affected by bacterial structure in the TBC treatment.The TBC amendment can effectively improve the structural composition of soil bacteria under Cd stress and enhance the pathways of decreasing soil Cd availability as well.The results might facilitate the development of in-situ remediation programs in Cd-contaminated soils in the future.
Occurrence of polycyclic aromatic hydrocarbons in the estuarine sediments of the Taihu Lake and their associated toxic effects on aquatic organisms

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous toxic organic pollutants in the natural environment that are strongly associated with socioeconomic activities.Exploring the distribution,sources,and ecological toxicity of PAHs is essential to abate their pollution and biological risks.The 16 priority PAHs in different lakeside city estuarine sediments in the northern Taihu Lake in China were determined using gas chromatography-mass spectrometry.Results showed that total concentrations of PAHs (ΣPAHs) ranged from 672.07 to 5 858.34 ng g~(-1),with a mean value of 2 121.37 ng g~(-1).High-molecular-weight PAHs (4-6 rings) were dominant,accounting for 85% of the ΣPAHs detected.Due to the barrier of gate/dam in the estuarine area,the concentrations of PAHs in the sediments were significantly different between the river mouth and lake side.Changes in total organic carbon (TOC) content and the spatial distribution of PAHs in the sediments were consistent.Sediment pollution assessment explored using the fuzzy evaluation model indicated 75% of slight PAH pollution.Some estuarine sediments (22%) concentrated in the east of the Wuli Lake in the Meiliang bay of the Taihu Lake were moderately or heavily polluted.The PAHs may lead to occasional detrimental biological consequences in the area.Diagnostic ratios and principal component analysis-multiple linear regression suggested vehicle emission and natural gas combustion as the primary PAH contributors (81%).
Research on disruptive design pre-identification in the preliminary design phase of aero engine flow pass multidisciplinary optimization

In aero engine design, determining whether the preliminary design will have disruptive effects on the detailed design is the key to multidisciplinary design optimization in the preliminary design stage. In order to adapt to the non-orthogonal parameter value range caused by the selfconstrained parametric modeling method, a non-orthogonal space mapping method that maps the optimal Latin hypercube sampling points of the traditional orthogonal design space to the non-orthogonal design space is proposed. Based on the logical regression method in machine learning field, a kind of feasible domain boundary identification method is employed to identify whether the sample spatial response meets the relevant criteria. The method proposed in this paper is used to identify and analyze the key technologies of the high-pressure turbine mortise joint structure. It is found that the preliminary design of the aero engine may lead to the failure to obtain a mortise joint structure meeting the design requirements in the detailed design stage. The mortise joint structure needs to be pre-optimized in the preliminary design stage.
Large-area Flexible Organic Solar Cells: Printing Technologies and Modular Design

Flexibility is the most prominent advantage of organic solar cells (OSCs) compared with traditional photovoltaic devices, showing an irreplaceable commercial potential. Currently, the maximum power conversion efficiencies (PCEs) of single-junction OSCs have been over 19% and 16% upon rigid and flexible substrates, respectively, which meet the criteria for commercial application. Extensive research efforts are under way, such as device configuration design, interface/photosensitive layer synthesis, transparent electrode modification and printing technology innovation, however, the reasonable selection of printing technologies, the huge performance loss of large-area printing process and the structural design of flexible modules are still the bottlenecks, limiting the commercialization of OSCs. This review focuses on the technical challenges and rational modular configuration design for printing preparation of flexible high-efficiency large-area organic devices, from the aspects of the functional layer material selection, printing process research status and large-scale efficiency losses. These will promote the integrated applications of printable organic semiconductor materials for next-generation clean energy and appeal extensive attentions in wearable electronics, building-integrated photovoltaics and Internet of Things, etc.
Intercellular transfer of activated STING triggered by RAB22A-mediated non-canonical autophagy promotes antitumor immunity

STING, an endoplasmic reticulum (ER) transmembrane protein, mediates innate immune activation upon cGAMP stimulation and is degraded through autophagy. Here, we report that activated STING could be transferred between cells to promote antitumor immunity, a process triggered by RAB22A-mediated non-canonical autophagy. Mechanistically, RAB22A engages PI4K2A to generate PI4P that recruits the Atg12-Atg5-Atg16L1 complex, inducing the formation of ER-derived RAB22A-mediated non-canonical autophagosome, in which STING activated by agonists or chemoradiotherapy is packaged. This RAB22A-induced autophagosome fuses with RAB22A-positive early endosome, generating a new organelle that we name Rafeesome (RAB22A-mediated non-canonical autophagosome fused with early endosome). Meanwhile, RAB22A inactivates RAB7 to suppress the fusion of Rafeesome with lysosome, thereby enabling the secretion of the inner vesicle of the autophagosome bearing activated STING as a new type of extracellular vesicle that we define as R-EV (RAB22A-induced extracellular vesicle). Activated STING-containing R-EVs induce IFNβ release from recipient cells to the tumor microenvironment, promoting antitumor immunity. Consistently, RAB22A enhances the antitumor effect of the STING agonist diABZI in mice, and a high RAB22A level predicts good survival in nasopharyngeal cancer patients treated with chemoradiotherapy. Our findings reveal that Rafeesome regulates the intercellular transfer of activated STING to trigger and spread antitumor immunity, and that the inner vesicle of non-canonical autophagosome originated from ER is secreted as R-EV, providing a new perspective for understanding the intercellular communication of organelle membrane proteins.
In-depth understanding of ionic liquid assisted perovskite film formation mechanism for two-step perovskite photovoltaics

Ionic liquids(ILs)have been widely applied in the one-step fabrication of perovskite with noticeable enhancement in the device performance. However, in-depth mechanism of ionic-liquid-assisted perovskite film formation is not well understood for also important two-step perovskite fabrication method,with better control of crystallization behavior. In this work, we introduced ionic liquid methylammonium formate(MAFa)into organic salt to produce perovskite film via a two-step method. Systematic investigations on the influence of MAFa on the perovskite thin film formation mechanism were performed. Ionic liquid is shown to assist lowering the perovskite formation enthalpy upon the density functional theory(DFT)calculation, leading to an accelerated crystallization process evidenced by in-situ UV-Vis absorption measurement. A gradient up-down distribution of ionic liquid has been confirmed by timeof- flight SIMS. Importantly, besides the surface passivation, we found the HCOO~- can diffuse into the perovskite crystals to fill up the halide vacancies, resulting in significant reduction of trap states. Uniform perovskite films with significantly larger grains and less defect density were prepared with the help of MAFa IL, and the corresponding device efficiency over 23% was obtained by two-step process with remarkably improved stability. This research work provides an efficient strategy to tune the morphology and opto-electronic properties of perovskite materials via ionic-liquid-assisted two-step fabrication method, which is beneficial for upscaling and application of perovskite photovoltaics.
Unraveling the morphological evolution mechanism of solid sulfur species in lithium-sulfur batteries with operando light microscopy

Solid-liquid phase conversion between various sulfur species in lithium-sulfur(Li-S)batteries is a fundamental reaction of the sulfur cathode. Disclosing the morphological evolution of solid sulfur species upon cycling is of great significance to achieving high energy densities. However, an in-depth investigation of the internal reaction is still lacking. In this work, the evolution process of solid sulfur species on carbon substrates is systematically studied by using an operando light microscope combined with in situ electrochemical impedance spectra technology. The observation of phenomena such as bulk solid sulfur species can form and dissolve independently of the conductive substrates and the transformation of supercooled liquid sulfur to crystalline sulfur. Based on the phenomena mentioned above, a possible mechanism was proposed in which the dissolution reaction of solid sulfur species is a spatially free reaction that involves isotropic physical dissolution, diffusion of molecules, and finally the electrochemical reaction. Correspondingly, the formation of solid sulfur species tends to be a form of crystallization in a saturated solution rather than electrodeposition, as is commonly believed. Our findings offer new insights into the reaction of sulfur cathodes and provide new opportunities to design advanced sulfur cathodes for Li-S batteries.
Unveiling the key factor affecting the illumination deterioration and response measures for lead halide perovskite solar cells

So far, it's been widely acknowledged that the PbI_2 decomposition under illumination mainly accounts for the degradation of perovskite solar cells(PSCs)under maximum power point(MPP)tracking condition. However, PSCs without excess PbI_2 were also reported to deteriorate rapidly under the same condition. Here, we demonstrate that the key to enhance PSCs stability under MPP tracking condition is not to have fascinating surface morphology with effective suppression of nonradiative recombination traps but to prevent the migration of iodine ion(I~-)under light illumination. By partially substituting methylammonium chloride(MACl)with methylammonium iodide(MAI)and simutaneouly introducing I_2 during the sequential deposition, the iodine vacancies in perovskite films are substantially suppressed, thereby limiting the pathways for I~- migration. As a consequence, PSCs with efficiency of 24.28% are fabricated with remarkably enhanced working stability.
Tuning anionic redox activity to boost high-performance sodium-storage in low-cost Na_(0.67)Fe_(0.5)Mn_(0.5)O_2 cathode

Na-based layered iron-manganese oxide Na_(0.67)Fe_(0.5)Mn_(0.5)O_2 containing only low-cost elements is a promising cathode for Na-ion batteries used in large-scale energy storage systems. However, the poor cycle stability restricts its practical application. The capacity decay of Na_(0.67)Fe_(0.5)Mn_(0.5)O_2 mainly originates from the irreversible anionic redox reaction charge compensation due to the high-level hybridization between oxygen and iron. Herein, we rationally design a surface Ti doping strategy to tune the anionic redox reaction activity of Na_(0.67)Fe_(0.5)Mn_(0.5)O_2 and improve its Na-storage properties. The doped Ti ions not only enlarge the Na migration spacing layer but also improve the structure stability thanks to the strong Ti-O bond. More importantly, the d0-shell electronic structure of Ti~(4+) can suppress the charge transfer from the oxidized anions to cations, thus reducing the anionic redox reaction activity and enhancing the reversibility of charge compensation. The modified Na_(0.67)Fe_(0.5)Mn_(0.5)O_2 cathode shows a reversible capacity of 198 mA h g~(-1) and an increased capacity retention from 15% to 73% after about 1 month of cycling. Meanwhile, a superior Na-ion diffusion kinetics and rate capability are also observed. This work advances the commercialization process of Na-based layered iron-manganese oxide cathodes;on the other hand, the proposed modification strategy paves the way for the design of high-performance electrode materials relying on anionic redox reactions.
Lithiophilic seeds and rigid arrays synergistic induced dendrite-free and stable Li anode towards long-life lithium-oxygen batteries

High energy density lithium-oxygen battery(LOB)is currently regraded as a promising candidate for next-generation power system. However, the dendrite and instability issues of Li metal anode lead to its poor cyclic stability and low energy density. In this work, lithiophilic Al_2O_3 seeds induced rigid carbon nanotube arrays(CNTA)/three-dimensional graphene(3DG)is developed as a host material for Li anode,namely Al_2O_3-CNTA/3DG. It is demonstrated that the lithiophilic feature of Al_2O_3 seeds and the enhanced rigidity of arrays can synergistically induce the uniform Li flux, inhibit the collapse of arrays, and stabilize electrolyte/electrode interfaces. As a result, the Al_2O_3-CNTA/3DG-Li anode delivers a high Coulombic efficiency above 97% after 140 cycles(8 mAh cm~(-2) at 4 mA cm~(-2)). With this anode and the breathable CNTA/3DG cathode, the full LOB exhibits a significantly increased life-span up to 160 cycles(500 mAh g~(-1) at 100 mA g~(-1)), which is almost 3 times longer than that with pure Li foil as the anodes. This work demonstrates a new approach to highly reversibly long-cycling performance of LOBs towards practical application.
Delicate surface vacancies engineering of Ru doped MOF-derived Ni-NiO@C hollow microsphere superstructure to achieve outstanding hydrogen oxidation performance

Surface vacancy defects, as the bridge between theoretical structural study and the design of heterogenous catalysts, have captured much attention. This work develops a metal-organic framework-engaged replacement-pyrolysis approach to obtain highly dispersed Ru nanoparticles immobilized on the vacancy-rich Ni-NiO@C hollow microsphere(Ru/Ni-NiO@C). Fine annealing at 400 °C introduces nickel and oxygen vacancies on Ru/Ni-NiO@C surface, resulting in an improved electrical conductivity and rapid mass-charge transfer efficiency. Ru/Ni-NiO@C with a hollow micro/nanostructure and interconnected meso-porosity favors the maximal exposure of abundant active sites and elevation of hydrogen oxidation reaction(HOR)activity. Experimental results and density functional theory(DFT)calculations reveal that an electronic effect between Ru and Ni-NiO@C, in conjunction with nickel/oxygen vacancies in the NiO species could synergistically optimize hydrogen binding energy(HBE)and hydroxide binding energy(OHBE). The HBE and OHBE optimizations thus created confer Ru/Ni-NiO@C with a mass activity over 7.75 times higher than commercial Pt/C. Our work may provide a constructive route to make a breakthrough in elevating the hydrogen electrocatalytic performance.
