The limited long-term stability of metal halide perovskite-based solar cells is a bottleneck in their drive toward widespread commercial adaptation. The organic hole-transport materials (HTMs) have been implicated in the degradation, and metal oxide layers are proposed as alternatives. One of the most prominent metal oxide HTM in organic photovoltaics is MoO3. However, the use of MoO3 as HTM in metal halide perovskite-based devices causes a severe solar cell deterioration. Thus, the formation of the MoO3/CH3NH3PbI3-xClx (MAPbI3-xClx) heterojunction is systematically studied by synchrotron-based hard X-ray photoelectron spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Raman spectroscopy. Upon MoO3 deposition, significant chemical interaction is induced at the MoO3/MAPbI3-xClx interface substoichiometric molybdenum oxide is present, and the perovskite decomposes in the proximity of the interface, leading to accumulation of PbI2 on the MoO3 cover layer. this website Furthermore, we find evidence for the formation of new compounds such as PbMoO4, PbN2O2, and PbO as a result of the MAPbI3-xClx decomposition and suggest chemical reaction pathways to describe the underlying mechanism. These findings suggest that the (direct) MoO3/MAPbI3-xClx interface may be inherently unstable. It provides an explanation for the low power conversion efficiencies of metal halide perovskite solar cells that use MoO3 as a hole-transport material and in which there is a direct contact between MoO3 and perovskite.
Exposure to peer aggression (PA) and bullying victimization (BV) are both expressions of peer victimization.

In four age-sex groups, (1) Can exposure to PA and BV be considered distinct experiences?; (2) In what extent adolescents exposed to PA consider themselves bullying victims?; (3) What is the effect of the number of experienced PA events on BV?

This cross-sectional study evaluated a probabilistic community-based sample of 669 adolescents (11-15 years, 51.7% girls). A three-stage probabilistic sampling plan involved a random selection of census units, eligible households, and target child. A 15-item scale investigated exposure to PA events (physical aggression, verbal harassment, social manipulation) occurring more than once in the past six months. BV occurring more than once a week or most days in the past six months was investigated after presenting a BV definition to respondents which required them to feel harmed by their victimization experiences.

Adolescents exposed to PA and/or BV reported PA only (76.2%), BV only (4.7%) and both (19.1%). Rates of BV among those exposed to PA 11-to-12-year-old boys (22.7%), 13-to-15-year-old boys (9.7%), 11-to-12-year-old girls (46.5%) and 13-to-15-year-old girls (13.2%). Multiple logistic regression analysis (outcome = BV) found a significant interaction between PA, age, and sex. PA events had a significant effect on BV for all except older girls.

Exposure to PA and BV are different constructs; few older boys exposed to PA consider themselves bullying victims; and older girls are less affected by PA when it comes to BV.

The aim of this study was to translate the Fear Survey Schedule for Infants-Preschoolers (FSSIP) for Brazilian Portuguese and to examine its reliability and validity for assessing fears among Brazilian preschoolers.

Two-independent bilingual professionals conducted translation and back-translation of the original survey. The translated version was used to assess 152 preschool children divided in two groups Clinical - 71 children referred for treatment for nighttime fear, and Control - 81 children enrolled in kindergarten who were not referred for any mental health service in the previous 6 months. All parents filled out the FSSIP, the Child Behavior Checklist (CBCL/1.5-5), and a sociodemographic questionnaire.

Cronbach's alpha for the entire sample was 0.949 (95% CI 0.94-0.96); for the Clinical Group 0.948 (95% CI 0.93-0.96), and for the Control Group 0.95 (95% CI 0.93-0.96). The mean score of fears was higher in the clinical group (60.19 vs 51.53, t = -2.056; p = 0.042), indicating acceptable discriminative validity. We also found positive, moderate and statistically significant correlations between FSSIP and most CBCL scores, indicating good convergent validity.

The Brazilian Portuguese version of the FSSIP showed good psychometric properties, and hence may be used in research and clinical settings to evaluate fears in preschoolers.

Herbal medicines, as a treatment method, have received a great deal of attention. The effects of two herbal medicines namely
and Echinacea on alleviation of clinical symptoms and hospitalization rate of suspected COVID-19 outpatients were examined.

A clinical trial with 100 suspected COVID-19 outpatients as participants was conducted. The participants were allocated randomly to two groups of 50 members. The intervention group received concurrent
(Tablet Vomigone 500mg II tds) and Echinacea (Tablet Rucoldup I tds) for sevendays in addition to the standard treatment. The control group only received the standard treatment (Hydroxychloroquine). After sevendays, alleviation of clinical symptoms and hospitalization rate were examined. In addition, 14days after treatment, the hospitalization was assessed again by telephone follow up.

The two groups were identical in terms of basic characteristics. Improvement level as to coughing, dyspnea, and muscle pain was higher in the intervention group (p value <0.05). There was no significant difference between the two groups in terms of the other symptoms. In addition, the hospitalization rate in the intervention and control groups were 2 and 6% respectively, which are not significantly different (p value >0.05).

Taking into account the efficiency and trivial side-effects of
and Echinacea, using them for alleviation and control of the clinical symptoms in COVID-19 outpatients is recommended.
