Additive engineering has been demonstrated to effectively mitigate carrier losses associated with high surface defects of perovskite at grain boundaries, bulk, and interfaces. Nevertheless, there are persistent challenges in enhancing the passivation effects interfaces without compromising extraction efficiency. In this work, a feasible strategy incorporating multiple functional groups developed simultaneously passivate boundaries/interfaces, enhance charge transport by tuning permittivity...
The high-performance hole transporting material (HTM) is one of the most important components for perovskite solar cells (PSCs) in promoting power conversion efficiency (PCE). However, low conductivity HTMs and their additional requirements doping post-oxidation greatly limits device performance. In this work, three novel pyrene-based derivatives containing methoxy-substituted triphenylamines units (PyTPA, PyTPA-OH PyTPA-2OH) are designed synthesized, where different numbers hydroxyl groups...
Abstract Background The etiology of reflux esophagitis (RE) is multi-factorial. This study analyzed the relationship depression, anxiety, lifestyle and eating habits with RE its severity further explored impact anxiety depression on patients’ symptoms quality life. Methods From September 2016 to February 2018, a total 689 subjects at Xuanwu Hospital Capital Medical University participated in this survey. They were divided into group (patients diagnosed gastroscopy, n = 361) control (healthy...
With the widespread application of permanent magnet synchronous motor (PMSM) drives, demand for safety and reliability has increased. Inverter open-circuit fault is a frequent severe failure that requires reliable detection remedial measures. This paper proposes an diagnosis technique based on voltage residual analysis does not require additional sensors. The proposed analyzes characteristics reference actual output under both healthy conditions. To achieve fast detection, it uses DC...
Qinghai spruce (Picea crassifolia Kom.) is an ecologically important species in the forest ecosystem of Qilian Mountains region China. Natural regeneration this critical to maintaining function. Here, we analyzed several biological indicators among naturally regenerating across elevations Pailugou watershed. Specifically, seedling density, basal diameter (BD), and plant height were measured, as soil physicochemical parameters, at 2700 m, 3000 3300 m above sea level. Differences correlations...
For the sake of public safety and citizen health, development efficient portable detection devices to nerve agents is critical. In this investigation, a naphthalimide‐rhodamine based dual‐chromophore, RNI‐P, was synthesized applied detect nerve‐agent mimic diethyl chlorophosphate (DCP) real agents. The probe exhibits inherently weak fluorescence due PET processes from both piperazine rhodamine units naphthalimide unit. It shows rapid enhancement DCP in aqueous solution, demonstrating...
Abstract During the service life of oil and gas pipelines, welded joints are critical areas that susceptible to fracture. This study aims investigate influence mechanical heterogeneity on fields at crack tip propagation paths in joints. Firstly, microstructure joint was analyzed, distribution properties specific local determined through hardness tests. Subsequently, dissimilar materials within were characterized using “Field” subroutine, examined. Additionally, various locations joints,...
Environmentally assisted cracking (EAC) is a slow crack growth phenomenon in dissimilar metal‐welded joints within the primary circuit of pressurized water reactors. Accurately analyzing mechanical state at EAC tip crucial for ensuring long‐term safety nuclear power equipment. In this study, microstructure analysis SA508‐52M‐316L welded joint was conducted to determine distribution properties its local regions through hardness testing. A user‐defined field subroutine (USDFLD) developed...
Background Zinc is an essential trace element for the human body. Recently, a novel Zn-binding peptide, Lys-Tyr-Lys-Arg-Gln-Arg-Trp (PP), was purified and identified from soy protein hydrolysates with high capacity (83.21 ± 2.65%) by our previous study. The preparation of meal (SMHs)-Zn complexes convenient low-cost, while PP (Lys-Tyr-Lys-Arg-Gln-Arg-Trp)-Zn have higher coordination rate but relatively cost. aim this study to investigate effect on zinc absorption in mice model, synthetic...
Surface runoff is a major component of the hydrological cycle, and it essential for supporting ecosystem services provided by grassland forest ecosystems. It practical importance to understand mechanisms dynamic processes in river’s basin, this study, we focused on restored montane Pailugou Basin Qilian Mountains, Gansu Province, China, since its water status extremely important large arid area local economies therein. Our purpose was determine annual variation surface because influence...
Abstract BACKGROUND The supplemental effect of zinc depends not only on adequate intake, but also how efficiently it is absorbed in the small intestine. In present study, weak hydrophobic peptides (WHP), strong (SHP), positively charged (PCP) and negatively (NCP) were isolated from soybean (SP). peptide‐Zn complexes (PCP‐Zn, NCP‐Zn, WHP‐Zn, SHP‐Zn SP‐Zn) prepared to compare their promotion absorption capacity Caco‐2 cells monolayers model. RESULTS We found that carboxyl, carbonyl amino...

Qinghai spruce forests, found in the Qilian mountains, are a typical type of water conservation forest and play an important role regulating regional balance quantifying changes controlling factors for evapotranspiration (ET) its components, namely, transpiration (T), evaporation (Es) canopy interceptions (Ei), spruce, which may provide rich information improving resource management. In this study, we partitioned ET based on assumption that total equals sum T, Es Ei, then analyzed...
Understanding runoff dynamics is vital for effective water management in climate-affected areas. This study focuses on the Dayekou basin China’s Qilian Mountains, known their high climate variability. Using 25 years of data (1994–2018) river runoff, precipitation, and temperature, statistical methods were applied to explore annual variations change impacts these parameters. Results reveal a significant variability (132.27 225.03 mm), precipitation (340.19 433.29 average temperature (1.38...
