The acidic, corrosive effect of sodium polystyrene sulfonate(PSS) in poly 3,4-ethylenedioxythiophene:sodium polystyrene sulfonate(PEDOT:PSS) limits the stability of inverted perovskite solar cells(PSCs) based on the ITO/PEDOT:PSS/perovskite/PCBM/BCP/Ag structure. In this work, a poly 3,4-ethylenedioxythiophene(PEDOT) hole transport layer(HTL) with high hole mobility and good catalytic performance was prepared by electrochemical cyclic voltammetry(CV) method for inverted PSCs. By controlling the CV cycles(from 1 to 5 cycles) and EDOT monomer solution concentration(from0.5 to 2.0 mmol·L^(-1)) of electrochemical deposition, the thickness, morphology, optical and electrochemical properties of PEDOT could be accurately adjusted. The optimal photovoltaic performance with current density(J_(sc)) of 22.19 mA·cm^(-2), open circuit voltage(V_(oc)) of 0.94 V, fill factor(FF) of 0.65 and photoelectric conversion efficiency of 13.56% was obtained when deposition of PEDOT with 1 CV cycle and EDOT concentration of 0.5 mmol·L^(-1). At this point, the perovskite showed good crystallization,optimal optical, charge transport and recombination performance, resulting in better V_(oc)and photoelectric conversion efficiency(PCE) compared to the devices with higher CV cycle numbers and 3,4-ethylenedioxythiophene(EDOT) concentration. For comparison with spin-coated PEDOT:PSS, the device with electrodeposited PEDOT showed improved J_(sc)and comparable V_(oc), which may result from its better charge transport and catalytic ability.The device with spin-coated PEDOT:PSS showed photoelectric conversion efficiency of 12.25%, which was lower than that based on electrodeposited PEDOT(13.56%) with1 CV cycles and 0.5 mmol·L^(-1) EDOT concentration. And the device with electrodeposited PEDOT as HTLs showed more excellent air stability. In ambient air((32 ± 5) ℃ and RH: 70% ± 20%), it still maintained more than 80%of the initial photoelectric conversion efficiency after1000 h. In comparison, the photoelectric conversion efficiency of the device with

研究紫云英-水稻制度下,稻秸还田和硝化抑制剂对水稻生长和镉(Cd)吸收的影响,为湖南双季稻田基于绿肥的稻米安全生产措施提供理论支撑。池栽微区试验设4个处理:紫云英(GM)、紫云英+化肥(GF)、紫云英+稻秸+化肥(GRF)、紫云英+稻秸+化肥+硝化抑制剂(GRFD)。分析了不同措施下的水稻产量与养分积累、稻米Cd吸收、土壤肥力及土壤Cd有效性和形态。相比GRF处理,GRFD处理早稻籽粒和稻秸产量分别增加7.0%和12.2%。GRFD处理下,早稻籽粒氮、磷、钾养分累积量较GRF处理分别增加5.5%、10.1%、6.8%。GF、GRF、GRFD处理早稻籽粒Cd含量较GM处理分别降低64.8%、67.3%、66.8%。GRFD处理早稻可溶性有机碳和可溶性有机氮含量,相比GRF处理分别降低41.2%和8.0%。GRFD处理早稻和晚稻土壤有效态Cd含量,相比GRF处理分别降低70.9%和66.0%,相比GF处理分别降低80.2%和61.4%;GRFD处理晚稻土壤可氧化态Cd含量相比GRF处理增加了52.6%,表明紫云英-稻秸-硝化抑制剂联合利用通过将土壤Cd转变为难以被水稻吸收的形态而降低其有效性。随机森林与相关性表明,早、晚稻速效钾与有效磷在限制水稻吸收Cd中均起到了关键作用。在紫云英-稻秸联合还田条件下,配施硝化抑制剂可提高水稻产量、促进水稻养分吸收,同时通过增加土壤速效钾和有效磷含量,进而减少水稻对Cd的吸收。

Background:Zoonoses are public health threats that cause severe damage worldwide.Zoonoses constitute a key indicator of One Health(OH)and the OH approach is being applied for zoonosis control programmes of zoonotic diseases.In a very recent study,we developed an evaluation system for OH performance through the global OH index(GOHI).This study applied the GOHI to evaluate OH performance for zoonoses in sub-Saharan Africa.Methods:The framework for the OH index on zoonoses(OHIZ)was constructed including five indicators,15 subindicators and 28 datasets.Publicly available data were referenced to generate the OHIZ database which included both qualitative and quantitative indicators for all sub-Sahara African countries(n=48).The GOHI algorithm was used to estimate scores for OHIZ.Indicator weights were calculated by adopting the fuzzy analytical hierarchy process.Results:Overall,five indicators associated with weights were generated as follows:source of infection(23.70%),route of transmission(25.31%),targeted population(19.09%),capacity building(16.77%),and outcomes/case studies(15.13%).Following the indicators,a total of 37 sub-Sahara African countries aligned with OHIZ validation,while 11 territories were excluded for unfit or missing data.The OHIZ average score of sub-Saharan Africa was estimated at 53.67/100.The highest score was 71.99 from South Africa,while the lowest score was 40.51 from Benin.It is also worth mentioning that Sub-Sahara African countries had high performance in many subindicators associated with zoonoses,e.g.,surveillance and response,vector and reservoir interventions,and natural protected areas,which suggests that this region had a certain capacity in control and prevention or responses to zoonotic events.Conclusions:This study reveals that it is possible to perform OH evaluation for zoonoses in sub-Saharan Africa by OHIZ.Findings from this study provide preliminary research information in advancing knowledge of the evidenced risks to strengthen strategies for effective control of zoonoses and

BACKGROUND Squamous cell carcinoma(SCC)of the nail bed is a poorly reported malignant subungual tumor.Because it presents with nonspecific symptoms and signs,it is frequently misdiagnosed by dermatologists or surgeons.A delay in diagnosis and/or wrong treatment might increase the possibility of disease progression.Thus,new perspectives are needed to assist dermatologists and surgeons with diagnosing and treating SCC.This rare case presented with a 2-year delay in the diagnosis of SCC teaches a valuable lesson.CASE SUMMARY A 62-year-old female presented with a non-healing subungual growth in the nail bed of the right middle finger for 2 years.The lesion was first medicated with iodine by the patient herself without any relief.Twenty months later,a dermatologist diagnosed the lesion as paronychia and treated it with nail avulsions repeatedly with no obvious alleviation.A lesionectomy confirmed the lesion was SCC.An extended excision of the tumor with amputation of the distal interphalangeal joint was subsequently performed.A biopsy of sentinel lymph nodes was negative.Due to the result of preoperative positron emission tomography-computed tomography scanning,sweeping of axillary lymph nodes was considered dispensable and was skipped.At the 2-year follow-up,the patient showed a quick recovery and no sign of recurrence.CONCLUSION Our successful diagnosis and treatment of the case highlights the need for additional attention to long-standing non-healing lesions of the nail bed and the necessity for discreet evaluation and customization of surgical interventions.

Since organoboron compounds readily undergo a diverse array of transformations and are widely used in various fields,the development of C-B-bondforming reactions have attracted considerable attention.Herein,we report a new method for forming C-B bonds by means of Cu-catalyzed ring-opening/borylation reactions of cyclopropenes.This method provides efficient access to a new type of stable allylborane-Lewis base adduct,which is a versatile synthon.The configuration of the products can be well controlled with this method,and some of the configurations we obtained are inaccessible by other catalytic methods for generating allylborons.Mechanistic studies indicated that the reactions proceed via insertion of an alkenyl Cu carbene—generated in situ by cyclopropene ring opening—into the B-H bond;the ring-opening step determines both the rate and stereochemistry.
