The Potential Game-Changer:A Concept-to-Proof Study on D:A Heterojunction-Free Organic Photovoltaics

Chinese Journal of Chemistry 2024年第3期42卷 252-258页

作者： lijian Zuo Sae Byeok Jo Xueliang Shi francis lin Alex Jen State Key laboratory of Silicon and Advanced Semiconductor Materials MOE Key Laboratory of Macromolecular Synthesis and FunctionalizationDepartment of Polymer Science and EngineeringZhejiang UniversityHangzhouZhejiang310058 China Department of Materials Science and Engineering University of WashingtonSeattleWAUSA School of Chemical Engineering Sungkyunkwan University (SKKU)Suwon16419 Republic of Korea School of Chemistry and Molecular Engineering East China Normal UniversityShanghai200062 China Department of Materials Science and Engineering City University of Hong KongKowloonHong KongChina Department of Chemistry City University of Hong KongKowloonHong KongChina Hong Kong Institute for Clean Energy Hong KongChina

Since 1986,the donor-acceptor (D:A) heterojunction has been regarded a necessity for high-efficiency organic photovoltaics (OPVs),due to its unique advantage in compensating the intrinsic limitations of organic semiconductors,such as high exciton binding energy and poor ambipolar charge mobility. While this adversely causes tremendous non-radiative charge recombination and instability issues,which currently become the most critical limits for commercialization of OPVs. Here,we present a concept-to-proof study on the potential of D:A heterojunction free OPV by taking advantage of recent progress of non-fullerene acceptors. First,we demonstrate that the “free carriers” can be spontaneously generated upon illumination in an NFA,i.e.,the 6TIC-4F single layer. Second,the 6TIC-4F layer also exhibits good ambipolar charge transporting property. These exceptional characteristics distinguish it from the traditional organic semiconductors,and relieve it from the reliance of D:A heterojunction to independently work as active layer. As a result,the subsequent OPV by simply sandwiching the 6TIC-4F layer between the cathode and anode yields a considerably high power conversion efficiency ~1%. Moreover,we find the D:A heterojunction free device exhibits two order of magnitude higher electroluminescence quantum efficiency and significantly reduced VOC loss by 0.16 eV compared to those of the D:A BHJ structure,validating its promise for higher efficiency in the future. Therefore,our work demonstrates the possibility of using D:A heterojunction-free device structure for high performance,that can potentially become the next game changer of OPV.

Usefulness of the Surgical Apgar Score to Predict the Occurrence of Major Complications in the Early Post-Operative Period of Major Surgeries: Experience of Two Second-Category Hospitals in Cameroon

引用

Open Journal of Anesthesiology 2024年第3期14卷 51-65页

Objective: The Surgical Apgar Score (SAS) is a tool for intraoperative stratification of the risk of serious complications in the early postoperative period. It varies from 0 to 10 points divided into three risk categories (0 to 4 high, 5 to 7 moderate, 8 to 10 low). The aim of the study was to evaluate its relevance in predicting the appearance of these complications. Material and methods: This descriptive and analytical study was carried out at the “laquintinie” Hospital in Douala and at the Central Hospital in Yaounde, Cameroon. The main data were collected on a population of patients over 18 years old and recorded on a survey form. They consisted of variables of main interest and exposure variables. Univariate and multivariate statistical analysis using top-down logistic regression models made it possible to evaluate the association of each variable of main interest and each exposure variable. The association was significant at P Results: Of the 88 patients studied, the SAS was 3 hours. In multivariate, this link persisted only and strongly for the SAS OR (IC) 0.1 (0.1 - 0.2) and p = 000. Conclusion: The study found a specific and powerful link between the SAS score lications in the early postoperative period, in favor of its relevance in predicting them.

Impact on Soil Organic C and Total Soil N from Cool- and Warm-Season legumes Used in a Green Manure-Forage Cropping System

引用

Agricultural Sciences 2024年第3期15卷 333-357页

作者： Clark B. Neely francis M. Rouquette Jr. Cristine l.S. Morgan Frank M. Hons William l. Rooney Gerald R.

Annual forage legumes are important components of livestock production systems in East Texas and the southeastern US. Forage legumes contribute nitrogen (N) to cropping systems through biological N fixation, and their seasonal biomass production can be managed to complement forage grasses. Our research objectives were to evaluate both warm- and cool-season annual forage legumes as green manure for biomass, N content, ability to enhance soil organic carbon (SOC) and soil N, and impact on post season forage grass crops. Nine warm-season forage legumes (WSl) were spring planted and incorporated as green manure in the fall. Forage rye (Secale cereale l.) was planted following the incorporation of WSl treatments. Eight cool-season forage legumes (CSl) were fall planted in previously fallow plots and incorporated as green manure in late spring. Sorghum-sudangrass (Sorghum bicolor x Sorghum bicolor var. sudanense) was planted over all treatments in early summer after forage rye harvest and incorporation of CSl treatments. Sorghum-sudangrass was harvested in June, August and September, and treatments were evaluated for dry matter and N concentration. Soil cores were taken from each plot, split into depths of 0 to 15, 15 to 30 and 30 to 60 cm, and soil C and N were measured using combustion analysis. Nylon mesh bags containing plant samples were buried at 15 cm and used to evaluate decomposition rate of above ground legume biomass, including change in C and N concentrations. Mungbean (Vigna radiata l. [Wilczek]) had the highest shoot biomass yield (6.24 t DM ha-1) and contributed the most total N (167 kg∙ha-1) and total C (3043 kg∙ha-1) of the WSl tested. Decomposition rate of WSl biomass was rapid in the first 10 weeks and very slow afterward. Winter pea (Pisum sativum l. spp. sativum), arrow leaf clover (Trifolium vesiculosum Savi.), and crimson clover (Trifolium incarnatum l.) were the most productive CSl in this trial.

legume Green Manure and Intercropping for High Biomass Sorghum Production

引用

Agricultural Sciences 2024年第6期15卷 605-621页

作者： Clark B. Neely francis M. Rouquette Jr. Cristine l. S. Morgan Frank M. Hons William l. Rooney Gerald R. Smith Department of Soil and Crop Science Washington State University Pullman WA USA Texas A&M Agrilife Research Overton TX USA Soil Health Institute Morrisville NC USA Department of Soil and Crop Science Texas A&M University College Station TX USA

Before the advent of cheap, synthetic fertilizers, legumes were commonly used as green manure crops for their ability to fix atmospheric nitrogen (N). A three-year study at Overton, TX examined legume integration into high-biomass sorghum (Sorghum bicolor l.) production systems on a lilbert loamy fine sand recently cultivated after a fertilized bermudagrass [Cynodon dactylon (l.) Pers.] pasture. In this split-split plot design, ‘Dixie’ crimson clover (Trifolium incarnatum l.) and ‘Iron and Clay’ cowpea (Vigna unguiculata l.) were integrated into a high-biomass sorghum production system to evaluate impacts on N concentration, C concentration, and yield of high-biomass sorghum and their impacts on soil total N and soil organic carbon (SOC). Main plots were split into crimson clover green manure (ClGM) and winter fallow (FAll) followed by three sub-plots split into warm-season crop rotations: cowpea green manure (CPGM), cowpea-sorghum intercrop (CPSR), and sorghum monocrop (SORG). Three N fertilizer treatments (0, 45, 90 kg N∙ha−1) were randomized and applied as sub-sub plots. The ClGM increased (P sorghum biomass yield (16.5 t DM∙ha−1) 28% in year three but had no effect in the first two years. The CPSR treatment reduced sorghum yield up to 62% compared to SORG;whereas CPGM increased sorghum yield 56% and 18% the two years following cowpea incorporation. Rate of N fertilizer had no effect on sorghum biomass yield. Decrease in SOC and soil N over time indicated mineralization of organic N and may explain why no N fertilizer response was observed in sorghum biomass yield. Cowpea showed strong potential as a green manure crop but proved to be too competitive for successful intercropping in high-biomass sorghum production systems.
