Recent Advances in Synthesis and Properties of Hybrid Halide Perovskites for Photovoltaics

引用

Nano-Micro Letters 2018年第4期10卷 167-200页

作者： C.C.Vidyasagar blanca M.Muoz Flores Víctor M.Jimnez Prez Universidad Autónoma de Nuevo León Facultad de Ciencias Químicas Ciudad Universitaria School of Basic Sciences and Research in Chemistry Rani Channamma University

The progress made by the scientific community in emerging photovoltaic technologies over the past two decades has been outstanding. Numerous methods have been developed for the preparation of hybrid organic–inorganic perovskite solar cells. The power conversion efficiency has been up to 14% by a one-step vacuum deposition technique. A serious concern is the toxicity of the materials. In this review, several methods aimed at resolving these problems to some extent have been compiled, including eco-friendly synthesis. Further efficiency enhancements are expected following optimization, and a better fundamental understanding of the internal electron charge transfer, electron–hole diffusion to the corresponding layers, flexibility, and stability-dependent bandgaps is reported. This paper explores the green synthesis of organic–inorganic perovskites for industrialization. Concerning the above facts, a simple low-cost model called‘‘dispersed photovoltaic cells' ' is presented.

AIM To determine a potential relationship between serum undercarboxylated(uc OC) concentration and cardiovascular risk factors in type 2 diabetes(T2D) patients and healthy subjects(HS).METHODS A cross-sectional study was conducted on 140 subjects classified into two groups, 70 with T2D and 70 HS. Medical history and physical examination with anthropometric measurements were obtained from all subjects. Body fat percentage was determined by bioelectrical impendency analysis. Serum uc OC concentration was determined by enzyme immunoassay,while serum levels of insulin and hsC RP were obtained using high sensitivity enzyme-linked immunosorbent assay. Insulin resistance was determined using the homeostasis model assessment-IR. Lipid profile [triglycerides,total cholesterol(TC), high-density lipoproteins(HDL-c),low density lipoproteins(LDL-c), very low-density lipoproteins] was determined by spectrophotometry and standard formulas when applicable. RESULTS The T2D patient group showed significantly higher values of waist circumference, waist-to-hip ratio, systolic blood pressure(SBP), diastolic blood pressure(DBP),current smoking, and alcohol use when compared to the HS group(P gnificantly lower serum ucO C concentration in T2D than in HS(1.5 ± 1.4vs 2.3 ± 1.8, P g plasma glucose(r =-0.283, P group, serum uc OC concentration was inversely correlated with BMI(r =-0.310, P ge(r =-0.311,P group a positive correlation between serum levels of uc OC and SBP(r = 0.277, P < 0.05)was observed.

Origami Fiction： Psychological Horror in Interactive Narrative

引用

Journal of Philosophy Study 2014年第3期4卷 210-215页

作者： blanca Estela Lopez Perez Universidad Autonoma Metropolitana

One of the most relevant elements in contemporary narrative systems is the atmosphere creation. Even when talking about new digital media, interactive narratives can still be supported by strategies used by former media like cinema and television; namely, character design as well as the setting bonded to architectural space design. These elements are offered to the players through graphic representations that are intended to convey not only an uncanny atmosphere but also an aesthetic experience for psychological horror narratives in videogames. With narrative proposals close to interactive movies, titles like Heavy Rain manage to create a gloomy mood by using basic elements of style such as form, composition, and light, and also open the opportunity to get emotionally involved with the characters through everyday life choices. Even though Heavy Rain is not considered as an action videogame, its narrative audiovisual system is fully able to create enough tension and suspense in order to offer a quite intense aesthetic experience. However, most of its narrative resources are taken from cinema and television audiovisual strategies to tell stories and to hook the audience. Therefore, the study of former narrative systems both as language and human thought and psyche, could allow designers to create more effective interactive narratives for contemporary audiences.
