Engagement in high‐leverage science teaching practices among novice elementary teachers
Authors: Davis Elizabeth A. , Palincsar Annemarie S. 
Published: September 2022

AbstractAs part of learning to teach, teachers must learn to use a range of teaching practices. In this longitudinal study the authors explore how novice elementary teachers learn to engage in a set of high‐leverage science teaching practices, such asleading a science sensemaking discussionandsetting up and managing small‐group investigations. Drawing primarily on videorecords from 33 lesson enactments, supplemented by transcripts of interviews with the participants, the authors follow five participants from their second year of a teacher education program through their first year of teaching. Findings suggest that high‐leverage science teaching practices can be untangled from one another and that teachers mostly demonstrated some important strengths in the dimensions of the practices. Furthermore, the teachers were able to use the practices synergistically, though in different ways, toward their goal of supporting students' sensemaking. The findings also suggest that teachers' engagement in the practices varied considerably as a function of lesson and school context. The findings have implications for the design of practice‐based teacher education experiences and for scholarship on teacher development.

AbstractCurcumin (Cur) has shown its potential in the treatment of a wide variety of ailments. As a result, several investigations on curcumin have been conducted in vitro, in vivo, and in clinical trials. Regrettably, researchers have largely lost interest in this excellent scaffold due to its chemical instability, poor solubility, and rapid metabolism, which directly affect its pharmacological properties. Alternatively, the researchers are working on it to improve the solubility and biological half‐life, it is one of the most researched natural phytochemical to date. Among these, Dehydrozingerone (DZG), a curcumin half structure has garnered considerable research interest due to a wide spectrum of its biological activities. Thus, this study offers insight into the pharmacological activity of modified DZG conjugates (incorporate multiple effective modifications to the various positions), which have been developed since 2016. Additionally, the structure‐activity relationship (SAR) of DZG hybrids was illustrated for their specific pharmacological properties. This review presents an update for the scientific community, which could assist in addressing the gaps, challenges and pharmacological aspects of DZG.
Ditopic Chemodosimeter for Selective Detection of Nerve Agent Tabun Simulant DCNP
Authors: Maurya Chandra Kant , Pathak Uma , Gupta Pradeep Kumar 
Published: September 2022

AbstractSelective optical detection of highly toxic nerve agents and their mimics like diethyl cyanophosphate (DCNP) is of paramount importance for armed forces and first responders in order to decide the suitable medical countermeasures. The reported optical chemical sensors for DCNP suffered from poor selectivity due to their single point covalent interaction with analyte. To overcome this limitation, we herein, report a novel protocol utilizing a ditopic chemodosimeter which, in presence of tetrabutylammonium hydroxide (TBAOH), underwent dual interaction with reactive subunits of DCNP, viz., electrophilic phosphorus and cyanide, to induce unique changes in its fluorescence as well as colorimetric properties. Other interfering analytes could not trigger the similar optical response in the sensing probe due to the absence of electrophilic phosphorus and cyanide. A truth table was constructed to reveal that only DCNP but not other analytes could induce changes in both fluorescence as well as colorimetric properties of sensing probe. The linearity range of the proposed method was found to be 30–70 μM while chromogenic limit of detection (LOD) was calculated to be 99 nM which are comparable to the reported methods. Thus, use of indigenously available 2‐hydroxy‐1‐naphthaldehyde as sensing probe without requiring further chemical manipulation represented a significant improvement over the literature methods for DCNP sensing.

Published: September 2022

AbstractVanadium is a long‐confined contaminant. In this study, graphene oxide (GO) was synthesized by the modified Hummers’ method and used to remove vanadium(IV). The adsorption isotherms and kinetics of vanadium(IV) on GO at pH 2.5 and three temperatures are measured in batch experiments. The influences of ionic strength is investigated and the regeneration of GO is evaluated by washing with HCl. The results show that the adsorption isotherm corresponds to Temkin model with an adsorption capacity of 70.56 mg/g at 298 K, while the kinetic process coincides with pseudo‐second‐order model and approaches to equilibrium in 6 h. The adsorption capacity of GO is not influenced by Na+ ionic strength, but sharply inhibited by Ca2+. The superior adsorption is dominated by electrostatic interaction, coordination bonding, and hydrogen bonding. Moreover, the GO is reusable, as shown by maintaining 53.4 % of the initial efficacy after five sequential adsorption‐desorption cycles.

AbstractAn electrocatalyst composed of RuO2 surrounded by interfacial carbon, is synthesized through controllable oxidization‐calcination. This electrocatalyst provides efficient charge transfer, numerous active sites, and promising activity for pH‐universal electrocatalytic overall seawater splitting. An electrolyzer with this catalyst gives current densities of 10 mA cm−2 at a record low cell voltage of 1.52 V, and shows excellent durability at current densities of 10 mA cm−2 for up to 100 h. Based on the results, a mechanism for the catalytic activity of the composite is proposed. Finally, a solar‐driven system is assembled and used for overall seawater splitting, showing 95% Faraday efficiency.

AbstractIn recent decades, the continuous depletion of fossil fuels and the increasingly serious environmental issue have aroused wide attention on the development of biopolymers based on renewable biomass. Lignin is the second most abundant organic bio‐based macromolecule second to cellulose, and it can be widely found in plants. Furthermore, various phenol derivatives can be obtained by their depolymerization processes. The development of bio‐renewable polymeric materials originating from lignin‐derivative phenol monomers, such as vanillin, syringaldehyde, eugenol, vanillyl alcohol, vanillic acid, and ferulic acid, will not only valorize the bio‐sourced materials but also effectively reduce petroleum resource consumption and mitigate the environmental pollution. Therefore, an updated overview of the synthesis processes of these bio‐based polymers developed in the past decade, which includes both thermosets and thermoplastics such as epoxy, phenolic, polyimine, polybenzoxazine, polyurethane, and polyesters, are elucidated. In addition, the applications of these bio‐based polymers and their composites in flame‐retarded materials, degradable and reprocessable materials, dielectric materials, optoelectronic materials, as well as smart responsive materials are also intensively discussed. In line with the gradual development of synthesis technologies, we believe that derivatives of lignin will turn into one of the most promising materials to be considered for the preparation of high‐performance and functional bio‐based polymer materials.

AbstractUse of MXenes (Ti3C2Tx), which belongs to the family of two‐dimensional transition metal nitrides and carbides by encompassing unique combination of metallic conductivity and hydrophilicity, is receiving tremendous attention, since its discovery as energy material in 2011. Owing to its precursor selective chemical etching, and unique intrinsic characteristics, the MXene surface properties are further classified into highly chemically active compound, which further produced different surface functional groups i. e., oxygen, fluorine or hydroxyl groups. However, the role of surface functional groups doesn't not only have a significant impact onto its electrochemical and hydrophilic characteristics (i. e., ion adsorption/diffusion), but also imparting a noteworthy effect onto its conductivity, work function, electronic structure and properties. Henceforth, such kind of inherent chemical nature, robust electrochemistry and high hydrophilicity ultimately increasing the MXene application as a most propitious material for overall environment‐remediation, electrocatalytic sensors, energy conversion and storage application. Moreover, it is well documented that the role of MXenes in all kinds of research fields is still on a progress stage for their further improvement, which is not sufficiently summarized in literature till now. The present review article is intended to critically discuss the different chemical aptitudes and the diversity of MXenes and its derivates (i. e., hybrid composites) in all aforesaid application with special emphasis onto the improvement of its surface characteristics for the multidimensional application. However, this review article is anticipated to endorse MXenes and its derivates hybrid configuration, which is discussed in detail for emerging environmental decontamination, electrochemical use, and pollutant detection via electrocatalytic sensors, photocatalysis, along with membrane distillation and the adsorption application. Finally, it is expected, that this review article will open up new window for the effective use of MXene in a broad range of environmental remediation, energy conversion and storage application as a novel, robust, multidimensional and more proficient materials.

Published: September 2022

AbstractAntiangiogenic therapy in combination with chemotherapeutic agents is an effective strategy for cancer treatment. However, this combination therapy is associated with several challenges including non‐specific biodistribution leading to systemic toxicity. Biomaterial‐mediated codelivery of chemotherapeutic and anti‐angiogenic agents can exploit their passive and active targeting abilities, leading to improved drug accumulation at the tumor site and therapeutic outcomes. In this review, we present the progress made in the field of engineered biomaterials for codelivery of chemotherapeutic and antiangiogenic agents. We present advances in engineering of liposome/hydrogel/micelle‐based biomaterials for delivery of combination of anticancer and anti‐angiogenesis drugs, or combination of anticancer and siRNA targeting angiogenesis, and targeted nanoparticles. We then present our perspective on developing strategies for targeting angiogenesis and cell proliferation for cancer therapy.
The Multidimensionality of Materiality: Bodies, Space, and Things in Transitions
Authors: Nägler Deborah , Wanka Anna 
Published: September 2022

AbstractThe article focuses on the importance of materiality within social practice in relation to processes of transition. Materiality is emphasized on the one hand in its material-spatial dimension and on the other hand in its physical dimension and its relevance for the reflection and research of transitions. This is demonstrated in the article by two empirical examples that focus on different transitions. By referring to different phases of life (old age and childhood) and the transition processes that take place during these phases, the contribution opens up a comprehensive and multi-layered view of the meaning of materiality – of things, bodies, and spaces - and its relevance in the discussion of transitions.
How Spatial Sensitivity Enriches Understanding Transitions in Childhood and Later Life
Authors: Freutel-Funke Tabea , Müller Helena 
Published: September 2022

AbstractSpace is a key element of human life that holds significance across the life course. Spaces, territories and symbolic arrangements are elements of social reality. This chapter examines the role of space in the context of transitions. Our conceptualization of space does not reduce it to qualities of an external environment but views it as a relational arrangement of people and features that are crucial for understanding transitions across the life course instead. Drawing from two empirical studies anchored in dispositive analysis and environmental psychology, we examine (a) transitions to children’s independent mobility, and (b) transitions into multigenerational cohousing. We ask: How can spatial sensitivity shape, challenge and enrich research on transitions in childhood and later life?
The Significance of Relationality in “Doing Transitions”
Authors: Settersten Richard A. , Stauber Barbara , Walther Andreas 
Published: September 2022

AbstractIt is common to interpret transitions as individual experiences that are largely the result of personal choices and behaviors or that are being worked out through individual processes. A foundational tenet of a Doing Transitions framework is that transitions are shaped and produced through social practices and are therefore not individual but relational – constantly co-produced or shared with, conditioned by, or otherwise involving multiple others. As such, a Doing Transitions framework makes visible the ways in which social interactions and processes create or reify individual and group differences, including how transition processes and outcomes are entangled in dynamics of power and empowerment, inequalities, politics and the welfare state. Instead of being seen as fixed entities, transitions are viewed as processual, dynamic, situated, and interwoven. This chapter makes an innovative contribution to the literature by systematizing this shift in observing and analyzing transitions. It recalls some core aspects of the theoretical turn offered by relational approaches and, against this backdrop, offers five distinct patterns of relationality and draws upon chapters of this book to illustrate how the science and practice of transitions can be advanced by leveraging these patterns of relationality.
Biographical Articulation in Transition
Authors: Eberle Noreen , Lütgens Jessica , Pohling Andrea , Spies Tina , Bauer Petra 
Published: September 2022

AbstractBiographical research approaches have been relevant for the analysis of transitions in the life course for a long time. From the beginning of a social science-based analysis of (auto-)biographical narratives, the “biography” as concept was oriented towards understanding the relationship between the development of individual identity against the background of collective phenomena as well as in their relevance for life histories. But biographical narrations are also connected to discourses and discursive orientation patterns. The concept of “articulation” in the sense of Stuart Hall allows for the building of a bridge between discourses and subject positions, in describing this as a suture between discourses and a subject. Based on the re-analysis of three narrative interviews which are linked to different biographical research projects, the article explains and illustrates three different modi of articulation linked to relevant biographical transitions. All three modi of articulation are examples that show the complexity and variety of social positioning and articulation in biographical turning points. At the end the article discusses the added value and the possibilities of this approach in understanding transitions in life courses from a biographical perspective.
Implementation Issues for a Highly Structured Research Report
Authors: Allen Robert B. 
Published: September 2022

AbstractWe have proposed that scientific research reports should be constructed entirely of structured knowledge rather than text. In an earlier paper, we emphasized Research Designs as a framework for structured research reports and described how a structured implementation might be applied to Pasteur’s classic swan-neck flask experiment. In this paper, we examine some of the issues encountered in developing that implementation using dynamic models. For instance, we consider issues associated with modeling state transitions.

Published: September 2022

AbstractFinding a suitable open access journal to publish scientific work is a complex task: Researchers have to navigate a constantly growing number of journals, institutional agreements with publishers, funders’ conditions and the risk of Predatory Publishers. To help with these challenges, we introduce a web-based journal recommendation system called B!SON. It is developed based on a systematic requirements analysis, built on open data, gives publisher-independent recommendations and works across domains. It suggests open access journals based on title, abstract and references provided by the user. The recommendation quality has been evaluated using a large test set of 10,000 articles. Development by two German scientific libraries ensures the longevity of the project.
