The paper describes the synthesis of conducting polyaniline-TiO2 (PANI-TiO2) nanocomposite by chemical oxidative polymerization method using aniline as a monomer. TiO2 nanoparticles were synthesized by sol gel method using TiCl4 and ethanol. Ultrasound synthesized TiO2 nanoparticles and nanocomposite were characterized by various spectroscopic techniques UV, FT-IR, XRD, SEM and TGA. The XRD pattern confirms the appearance of sharp diffraction patterns indicating the small sized, high purity TiO2 nano particles are highly agglomerated with spherical morphology. The PANI-TiO2 nanocomposite was employed as a promising heterocyclic, reusable catalyst for most of the organic synthesis. The advantages of this methodology are mild reaction conditions with short reaction time, excellent yields, low loading and reusability of catalyst.

Published: November 2024

The article presents the results of a quantitative study on the views of young Chilean high school students on the development of history and its future projections. It reflects on the impact of acceleration and unprecedented events in current societies and their incidence on the historical sensitivity of young people. The descriptive analysis shows the perception of change as a historical regularity, together with a disruption of history as progress and future events with a marked conflictive, dehumanized, and dystopian content. The emerging future visions are configured in a present connected to a recent past of dictatorial political violence, with visions about history that enhance power and inequalities, in a scenario of change of historical sensitivity that leads young Chileans to project a conflictive future governed by global technological powers as a continuity of the present.

Authors: Sigurjónsson Jóhann Örn 
Published: November 2024

Cognitive activation is a dimension of teaching quality which considers to what extent the teacher addresses the educational goal of student understanding, such as through successful implementation of demanding tasks. This study aimed to enrich empirical understandings of instructional formats and teacher-student interactions in cognitively activating lessons. Eight lessons were purposefully selected from a Nordic video database containing 125 lessons. The interactions in the lessons were analysed using reflexive thematic analysis and instructional formats using content analysis. Whole-class discussions and group work were the dominant formats. Four types of connection-making interactions were observed, connecting both within mathematics and to non-mathematical experience.

Objective: The aim of this work is to formulate a composite flour for porridges and biscuits based on plantain (musa paradisiaca), maize (zea mays), sesame (sesamum indicum) and N'sangui (pellonulla leonensis ) in order to diversify the sources of nutrients in infant flours.
Design of the study: the plant and fish materials were purchased and processed between 15 September 2022 and February 2023, followed by analyses in two laboratories at the site.
Methodology: A mixing plan was carried out with the different flours of each material using well-defined methods. Biochemical analyses were carried out on the composite flour formulations obtained. The porridge and biscuit preparations were subjected to organoleptic tests.
Results: The biochemical results of these formulations revealed that the nutrient levels vary from one formulation to another, the humidity level between 10 and 11%, ash between 1.8 and 4.82%, lipids between 6.6 and 16.75%, carbohydrates between 54.55 and 64.10%, proteins between 10.29 and 15.52% and energy values between 374 and 430.47kcal. The formulation coded F6 has the nutrient levels included in the range allowed by the World Health Organization standards on infant flours. The static test carried out on the porridges prepared from the different formulations produced showed that there is no significant difference in the appearance, smell, and taste of the porridges and a significant difference was noted on the color and overall acceptability. The sensory profile carried out on the biscuits prepared from the most appreciated formulation F5 of the porridges was highly appreciated by the tasters.
Conclusion: Overall, all formulations are close to the standards in force. The formulation coded F5 stood out as the most appreciated of the others.

The high mortality rate of melanoma is broadly associated with its metastatic potential. Tumor cell dissemination is strictly dependent on vascularization; therefore, angiogenesis and lymphangiogenesis play an essential role in metastasis. Hence, a better understanding of the players of tumor vascularization and establishing them as new molecular biomarkers might help to overcome the poor prognosis of melanoma patients. Here, we further characterized a linear murine model of melanoma progression and showed that the aggressiveness of melanoma cells is closely associated with high expression of angiogenic factors, such as Vegfc, Angpt2, and Six1, and that blockade of the vascular endothelial growth factor pathway by the inhibitor axitinib abrogates their tumorigenic potential in vitro and in the in vivo chicken chorioallantoic membrane assay. Furthermore, analysis of The Cancer Genome Atlas data revealed that the expression of the angiogenic factor ANGPT2 (P‐value = 0.044) and the lymphangiogenic receptor VEGFR‐3 (P‐value = 0.002) were independent prognostic factors of overall survival in melanoma patients. Enhanced reduced representation bisulfite sequencing‐based methylome profiling revealed for the first time a link between abnormal VEGFC, ANGPT2, and SIX1 gene expression and promoter hypomethylation in melanoma cells. In patients, VEGFC (P‐value = 0.031), ANGPT2 (P‐value < 0.001), and SIX1 (P‐value = 0.009) promoter hypomethylation were independent prognostic factors of shorter overall survival. Hence, our data suggest that these angio‐ and lymphangiogenesis factors are potential biomarkers of melanoma prognosis. Moreover, these findings strongly support the applicability of our melanoma progression model to unravel new biomarkers for this aggressive human disease.

Outcome Weighted Learning
Authors: Pan Yinghao , Zhao Ying‐Qi 
Published: May 2019

Abstract
Due to patient's heterogeneous response to treatment, there is a growing demand to develop treatment strategies according to individual characteristics, which could lead to better health outcomes. Individualized treatment rules aim to identify if, when, which, and to whom treatment should be applied. In this article, we review a general framework of outcome weighted learning, a recently proposed machine learning technique for estimating optimal individualized treatment rules. The methods developed within this framework can be applied to both a single‐stage setup, where a single treatment decision is to be made, and multi‐stage setups, where a sequence of treatment decisions will be made. Furthermore, the methods can handle different types of outcomes, including continuous, categorical, and survival outcomes, and various treatment formations such as binary/ordinal treatments and continuous dose level. Finally, we briefly discuss some recent developments in this research area.
Binary State Start‐Up Demonstration Tests
Authors: Griffith William S. , DePoy Smith Michelle L. 
Published: May 2019

AbstractStart‐up demonstration tests are used to determine the acceptability of equipment. These have been employed in a variety of situations including, among others, power generation equipment, emergency power systems, and security systems. This article discusses the various types of binary state start‐up demonstration tests that have been discussed in the literature. The structure of the tests varies based on the pattern of total or consecutive start‐ups required for acceptance or rejection of the equipment being tested. The assumptions on the start‐ups also vary as to whether they are considered as independent and identically distributed Bernoulli trials or have a more complex dependence structure. Start‐up demonstrations tests that utilize multiple stages and inspectors are also discussed.

Published: May 2019

AbstractIntercalation in few‐layer (2D) materials is a rapidly growing area of research to develop next‐generation energy‐storage and optoelectronic devices, including batteries, sensors, transistors, and electrically tunable displays. Identifying fundamental differences between intercalation in bulk and 2D materials will play a key role in developing functional devices. Herein, advances in few‐layer intercalation are addressed in the historical context of bulk intercalation. First, synthesis methods and structural properties are discussed, emphasizing electrochemical techniques, the mechanism of intercalation, and the formation of a solid‐electrolyte interphase. To address fundamental differences between bulk and 2D materials, scaling relationships describe how intercalation kinetics, structure, and electronic and optical properties depend on material thickness and lateral dimension. Here, diffusion rates, pseudocapacity, limits of staging, and electronic structure are compared for bulk and 2D materials. Next, the optoelectronic properties are summarized, focusing on charge transfer, conductivity, and electronic structure. For energy devices, opportunities also emerge to design van der Waals heterostructures with high capacities and excellent cycling performance. Initial studies of heterostructured electrodes are compared to state‐of‐the‐art battery materials. Finally, challenges and opportunities are presented for 2D materials in energy and optoelectronic applications, along with promising research directions in synthesis and characterization to engineer 2D materials for superior devices.

AbstractHalide perovskite films processed from solution at low‐temperature offer promising opportunities to make flexible solar cells. However, the brittleness of perovskite films is an issue for mechanical stability in flexible devices. Herein, photo‐crosslinked [6,6]‐phenylC61‐butyric oxetane dendron ester (C‐PCBOD) is used to improve the mechanical stability of methylammonium lead iodide (MAPbI3) perovskite films. Also, it is demonstrated that C‐PCBOD passivates the grain boundaries, which reduces the formation of trap states and enhances the environmental stability of MAPbI3. Thus, MAPbI3 perovskite solar cells are prepared on solid and flexible substrates with record efficiencies of 20.4% and 18.1%, respectively, which are among the highest ever reported for MAPbI3 on both flexible and solid substrates. The result of this work provides a step improvement toward stable and efficient flexible perovskite solar cells.

AbstractMolecular doping is a powerful method to fine‐tune the thermoelectric properties of organic semiconductors, in particular to impart the requisite electrical conductivity. The incorporation of molecular dopants can, however, perturb the microstructure of semicrystalline organic semiconductors, which complicates the development of a detailed understanding of structure–property relationships. To better understand how the doping pathway and the resulting dopant counterion influence the thermoelectric performance and transport properties, a new dimer dopant, (N‐DMBI)2, is developed. Subsequently, FBDPPV is then n‐doped with dimer dopants (N‐DMBI)2, (RuCp*mes)2, and the hydride‐donor dopant N‐DMBI‐H. By comparing the UV–vis–NIR absorption spectra and morphological characteristics of the doped polymers, it is found that not only the doping mechanism, but also the shape of the counterion strongly influence the thermoelectric properties and transport characteristics. (N‐DMBI)2, which is a direct electron‐donating dopant with a comparatively small, relatively planar counterion, gives the best power factor among the three systems studied here. Additionally, temperature‐dependent conductivity and Seebeck coefficient measurements differ between the three dopants with (N‐DMBI)2 yielding the best thermoelectric properties. The results of this study of dopant effects on thermoelectric properties provide insight into guidelines for future organic thermoelectrics.

AbstractDirect growth of electrocatalysts on conductive substrates is an emerging strategy to prepare air electrodes for flexible Zn‐air batteries (FZABs). However, electrocatalysts grown on conductive substrates usually suffer from disorder and are densely packed with “prohibited zones”, in which internal blockages shut off the active sites from catalyzing the oxygen reaction. Herein, to minimize the “prohibited zones”, an ordered multidimensional array assembled by 1D carbon nanotubes and 2D carbon nanoridges decorated with 0D cobalt nanoparticles (referred as MPZ‐CC@CNT) is constructed on nickel foam. When the MPZ‐CC@CNT is directly applied as a self‐supported electrode for FZAB, it delivers a marginal voltage fading rate of 0.006 mV cycle−1 over 1800 cycles (600 h) at a current density of 50 mA cm−2 and an impressive energy density of 946 Wh kg−1. Electrochemical impedance spectroscopy reveals that minimal internal resistance and electrochemical polarization, which is beneficial for the flash reactant shuttling among the triphase (i.e., oxygen, electrolyte, and catalyst) are offered by the open and ordered architecture. This advanced electrode design provides great potential to boost the electrochemical performance of other rechargeable battery systems.
