“…Then, the dilute solution diffusion model is designed to visually reflect the lead ion leakage (Figure 2h,i) and the specific configuration is perovskite (with or without Di‐g modified layer)/PCBM/BCP/Ag/PDMS layered structure with microcrack. [ 12,31,32 ] Similarly, for the unmodified perovskite model, the lead ion in bulk solution presents a circular diffusion structure centered on the microcrack, which directly proves the existence and diffusion trend of lead leakage. In contrast, when there is a Di‐g modification interface between the perovskite and PCBM layers, ion diffusion is rapidly limited at the Di‐g layer, greatly reducing the lead content in bulk solution.…”

Although outstanding power conversion efficiency (PCE) has been achieved in flexible perovskite solar cells, unsatisfactory operational stability and toxicity caused by the moisture transmittance of polymer packaging are still the bottleneck challenges that limit their applications. Herein, inspired by the non-selective permeability of inactivated cell membrane, the diphosphatidyl-glycerol (Di-g) is tactfully introduced as a self-shield interface upon the perovskite layer. 96% of lead leakage is suppressed because the amphipathic Di-g can simultaneously bind tightly to the divalent lead ion and afford an interfacial water-resistance. More importantly, the gradient distribution of lattice residual stress perpendicular to the substrate are optimized. The resultant flexible devices achieve a PCE of 20.29% and 15.01% at effective areas of 1.01 and 21.82 cm 2 respectively, yielding excellent environmental and mechanical stability. This strategy exhibits the feasibility of developing interfacial encapsulation to stabilize scalable PSCs with negligible lead leakage.

This paper describes the process for the development of a mathematical model for an in situ uranium leaching method. A phased modelling process in MATLAB is conducted from the injection well to the ore body and from the ore body to the extraction well. Then a parametric identification of the injection and extraction wells is made, as well as the ore body itself. In addition, the hydraulic-resistance dependence of the bottom-hole zone on the flow rate of an injected solution in an injection well is determined and a technique is suggested for determination of the flow-pressure characteristics of the extraction well.

Constant and efficient operation of technological processes without incidents is of a paramount importance for any enterprise. Nevertheless, if any incident happens, the operation staff should be properly trained in order to avoid serious consequences and such training should be as close to the reality as possible. Virtual training application (VTA) that we introduce by this paper can perfectly meet this target and can be widely used for effective staff training by modern companies and enterprises. This paper proposes VTA plans and specifications considering technical requirements and rules applied for production processes and training simulators. It elaborately presents how the simulation technology can be used based on the example of uranium in-situ leaching process analysis. Introduced VTA plans and specifications can help the training operator staff learn and simulate the mentioned above process and this knowledge can be obtained without interruption of the working process of an enterprise. Virtual simulator is based on a simulation model of the technological equipment, and the difficulty level of training and further development of the dynamics of the training developed with the help of artificial intelligence. Streszczenie. Ciągły i efektywny przebieg procesów technologicznych, bez występowania sytuacji nietypowych ma kluczowe znaczenie w działaniu każdego przedsiębiorstwa. Niemniej jednak, w takich przypadkach obsługa powinna być właściwie przeszkolona, co powinno zostać przeprowadzone w warunkach możliwie jak najbardziej zbliżonych do rzeczywistych. Niniejszy artykuł prezentuję aplikację wirtualnego trenażera (VTA-virtual training application), który może zostać szeroko wykorzystany w praktycznym szkoleniu personelu. W artykule zaprezentowano ponadto obejmowane przez VTA scenariusze działania, które biorą pod uwagę reguły i wymagania techniczne związane z danym procesem wytwórczym. Działanie VTA zostało pokazane na przykładzie technologii procesu ługowania uranu in situ. Zaimplementowane plany i specyfikacje pozwalają szkolonemu personelowi zrozumieć specyfikę wspomnianego procesu, co odbywa się bez jakiejkolwiek ingerencji w działanie przedsiębiorstwa. W trenażerze wykorzystano modele symulacyjne rzeczywistych urządzeń, a funkcjonowanie całości, dla różnych poziomów trudności trenażera, zostało zamodelowane dzięki zastosowaniu metod sztucznej inteligencji.
