Published: February 2024

AbstractLayered double hydroxides (LDHs) is a category of 2D materials that possess excellent physicochemical properties for enhancing photocatalytic (PC), electrocatalytic (EC), and photoelectrochemical (PEC) performances. However, pristine LDH encounters challenges like sluggish charge–carrier mobility, high rate of electron–hole recombination, low conductivity, and tendency to agglomerate, making them unsuitable for practical applications. Therefore, modifications such as composite preparations, co‐catalyst integration, semiconductor coupling, and ternary heterostructure engineering have been explored to disclose new possibilities for LDHs in PC, EC, and PEC applications. In the realm of semiconducting materials aimed at enhancing LDH productivity, quantum dots (QDs) i. e., 0D materials have proven to be effective due to their advantages, including abundant reserves, affordability, and environmental friendliness. This review explores the role of QDs as interlayer support, co‐catalyst, mediator, semiconductor, and sensitizer in QDs@LDH heterostructures to achieve superior photocatalytic activities. These QD‐infused heterostructures also deliver improved EC and PEC water–splitting performance coupled with long–term stabilities. Additionally, this review delves into characterization techniques, intrinsic structural features, and designing of the QD@LDH heterostructures. Future scopes and challenges in constructing and cutting–edge theoretical anticipations of QD@LDH are also discussed. This review may be a guiding light to a sustainable approach to outperform QD‐modified LDH for versatile catalysts.

Published: February 2024

AbstractA series of nickel hydroxyapatite catalysts were synthesized by the co‐precipitation method followed by calcination and reduction. These catalysts were employed for the aqueous phase hydrogenation of glucose to sorbitol. The Ni‐HAP catalyst with comparatively high surface area and acid‐base strength gave high sorbitol selectivity in 1 h. Ni‐HAP‐4 catalyst with moderate Ni (3.5 wt. %) content having smaller and highly dispersed nickel particles gives an excellent yield of sorbitol, 97 % in 1 h. The Ni‐HAP‐4 catalyst works well with other polar protic solvents. Different characterization techniques like XRD, TEM, SEM‐EDS, BET, NH3‐TPD, and CO2‐TPD were employed to analyze the Ni‐HAP‐4 catalyst.
Increasing the Sustainability of Pharmaceutical Grade Water Production
Authors: Rögener Frank 
Published: February 2024

AbstractWater serves for the production of pharmaceutical ingredients, intermediates and final products. Accordingly, the quality requirements are particularly high. Next to quality, sustainability of the production and climate change mitigation will play an increasingly important role. For instance, in 2015, the total global emissions of the pharma sector was significantly higher than the CO2 emissions generated by the automotive sector. Thus, efforts must be made at all stages of production of pharmaceuticals to reduce the environmental impact.

Published: February 2024

AbstractBackgroundPancreatic adenocarcinoma (PDAC) is associated with a 5‐year survival rate of less than 6%, and current treatments have limited efficacy. The diagnosis of PDAC is mainly based on a cytologic analysis of endoscopic ultrasound–guided fine‐needle aspiration (EUS‐FNA) samples. However, the collected specimens may prove noncontributory in a significant number of cases, delaying patient management and treatment. The combination of EUS‐FNA sample examination and KRAS mutation detection can improve the sensitivity for diagnosis. In this context, the material used for molecular analysis may condition performance.MethodsThe authors prospectively compared the performance of cytologic analysis combined with a KRAS droplet digital polymerase chain reaction (ddPCR) assay for PDAC diagnosis using either conventional formalin‐fixed, paraffin‐embedded cytologic samples or needle‐rinsing fluids.ResultsMolecular testing of formalin‐fixed, paraffin‐embedded cytologic samples was easier to set up, but the authors observed that the treatment of preanalytic samples, in particular the fixation process, drastically reduced ddPCR sensitivity, increasing the risk of false‐negative results. Conversely, the analysis of dedicated, fresh needle‐rinsing fluid samples appeared to be ideal for ddPCR analysis; it had greater sensitivity and was easily to implement in clinical use. In particular, fluid collection by the endoscopist, transportation to the laboratory, and subsequent freezing did not affect DNA quantity or quality. Moreover, the addition of KRAS mutation detection to cytologic examination improved diagnosis performance, regardless of the source of the sample.ConclusionsConsidering all of these aspects, the authors propose the use of an integrated flowchart for the KRAS molecular testing of EUS‐FNA samples in clinical routine.

AbstractThe regulation of surface active sites and structures is a key factor affecting the performance of photocatalysts. In order to prepare monodisperse anatase TiO2 mesoporous microspheres with higher specific surface area, smaller pore size and particle size, a dual‐surfactant orientation assembly method was selected. Graphene (NG) was selected as a cocatalyst to compound with mesoporous TiO2 and nickel doping was performed on the cocatalyst to improve the photocatalytic hydrogen production activity of the semiconductor photocatalyst. Through proper regulation and rational design, the semiconductor photocatalyst with desired properties was prepared. SEM characterization of mesoporous titanium dioxide (TiO2/Ni‐NG) with graphene cocatalyst proved that TiO2 nanospheres have good monodispersion, and TiO2 nanospheres are well supported on graphene cocatalyst. The composite material belonged to mesoporous group with the pore size being mainly distributed between 10–20 nm. The loading of graphene and Ni‐NG cocatalyst increased the absorption band edge by 9 nm and 38 nm, respectively, and the band gap decreased by 0.07 eV and 0.16 eV, respectively. The selection of graphene as cocatalyst improved the hydrogen production activity of photocatalyst and nickel doping was very effective in the modification of graphene. For reaction time of 2.5 h, the H2 production of TiO2/Ni‐NG material reached 1.767 mmol/g which was 7.27 times that of TiO2/NG composite material.

Does negative environmental performance feedback induce substantive green innovation? The moderating roles of external regulations and internal incentive
Authors: Sun Ziyuan , Sun Xiao , Dong Yuting 
Published: February 2024

AbstractWhen the environmental performance is below the aspiration, will firms make substantive changes? In order to answer this question, based on the behavioral theory of the firm, this paper examines the impact of negative environmental performance feedback on substantive green innovation (GI) and its influencing mechanism. It is found that the negative environmental performance feedback induces substantive GI, which is positively moderated by external regulations (i.e., government environmental regulation and public environmental concern) and internal incentive (i.e., executive equity incentive). Media pressure and risk preference act as mediators in the above promotion effect. Heterogeneity analysis shows that the above promotion effect as well as the moderating effects of external regulations are more pronounced in private firms, while the moderating effect of internal incentive is more pronounced in state‐owned firms. Furthermore, the above promotion and moderating effects are more pronounced after the ESG rating event of SynTao Green Finance Agency. This paper offers new sights into understanding the motives of substantive GI and policy suggestion for promoting firms to achieve sustainable development.
Exploring the hidden canvas: Conceptualisations of nature in early years curricula and standard documents in Turkey

Published: February 2024

AbstractThis paper examines underlying beliefs and values about nature within the early years education in Turkey, as reflected in the curricula and standards documents guiding instruction. Given that not every child has the opportunity for nature‐based education, it becomes essential to incorporate nature‐based learning into indoor classrooms. Employing a document analysis, we comprehensively analyse the Ministry of Education's Preschool Education Program (2013), Activity Book‐1 (2013a), and Activity Book‐2 (2018), which guides teachers in shaping their classroom practices, therefore providing in‐depth insights into the conceptualisations of nature. Our analysis reveals that ‘nature’ in these documents is characterised by its connection to and intersections of specific settings, concepts, and resources. Moreover, we found out that the identified patterns of relationships in the examined curriculum and standards documents demonstrate a purposeful initiative to engage preschool children in the realm of nature through various means, including conceptual comprehension, hands‐on interaction with materials, and direct involvement in natural surroundings. The intersections among these elements unveil a complex network of opportunities to promote an enhanced learning journey. By fostering a deeper understanding of the relationship between curriculum guidelines and nature activities, we aim to empower early childhood educators to embrace nature as an integral part of their classroom practices.
HIKS: A K‐shell‐weighted hybrid approach method for detecting influential nodes in complex networks using possible edge weights
Authors: Seshu Chakravarthy Thota , Selvaraj Lokesh 
Published: February 2024

SummaryThe influential node in the network is the node that has a higher impact on network functioning compared to the other nodes. The influential node detection in the complex network is crucial for rumor containment, virus spreading, viral marketing, and so forth. The researchers designed several influential node detection methods; still, detecting community and influential node selection with minimal computational complexity by considering the relationship between the nodes is challenging. Hence, an optimal community detection along with the hybrid K‐shell decomposition method is introduced in this research. Initially, the optimal community from the complex network is identified to reduce the computation burden. For this, the Improved Dingo (IDingo) algorithm is introduced by hybridizing the hunting behavior of Dingo and the rough encircling behavior of Harris Hawk. After detecting the optimal community, the influential node identification is devised using the proposed hybrid K‐shell decomposition methods. The potential edge weights are considered while ranking the nodes. The performance of a proposed method is analyzed using six various datasets and accomplished the maximal cluster coefficient of 0.56578, 0.25674, 0.24022, 0.5968, 0.23419, and 0.10196 for Karate, Dolphins, C‐Elegance, Facebook, Gowalla, and Power Grid Dataset.

Authors: Chouhan Sanjay , Malviya Leeladhar , Panda Debendra Kumar 
Published: February 2024

SummaryCurrent generation of mobile and wireless communication can have portable, compact, lightweight, highly reliable, easy to access, high coverage, high capacity, high SNR, and high gain antennas for non‐line‐of‐sight communication. MIMO technology provides these all and has data rate optimization, diversity, spatial multiplexing, and solution of multipath propagation. The current requirement for designing a compact MIMO antenna with better isolation is what spurred the creation of the proposed antenna. In this research, a mathematically inspired generalized antenna is proposed for 1.8/1.9 GHz application in the 1.5–2.1 GHz range. The bandwidth in this case is 600 MHz. The return loss is −78 dB at the resonant with more than 17 dB isolation in the entire band. The envelope correlation coefficient (ECC) is found below 5 × 10−3. The overall size of the antenna is 40 × 81.76 mm2on FR‐4 dielectric laminate. To improve the isolation further, a parasitic element is used between the radiating elements, and it provides 7 dB improvements in isolation and is confirmed by the surface current distribution. The radiation efficiency is more than 90%, and maximum current density of 29.9 A/m2 is found in the entire band. In this study, evaluation and discussion of additional antenna performance parameters channel capacity loss (CCL), mean effective gain (MEG), and specific absorption rate (SAR) are also included.
Cytotechnology schools: Future outlook
Authors: Rockson Lois 
Published: February 2024

AbstractRecent changes in the standard and guidelines governing the education of cytotechnologists herald in a new era of cytology education. The long‐discussed move to master level education and name change of the professional to cytologist signifies an alignment with current and projected scope of mid‐level diagnostic cytology practice. Cytotechnology programs going forward are charged with implementing curricular changes that prepare practitioners to perform tasks such as computer assisted screening, and cell block interpretation as well as to perform evidence‐based research methods. Cytotechnology education programs are sure to face challenges particularly in student recruitment and the hiring of expert faculty. There are however opportunities for programs to develop innovative teaching techniques, recruit from underrepresented groups and collaborate to develop needed curricular resources. The future outlook for cytotechnology programs is that they are at a turning point, poised to educate the next generation of pathology extenders who will continue to be integral members of the patient care team.
The children of parents who receive treatment for binge‐eating disorder experience improvements in disordered eating
Authors: Lydecker Janet A. , Ozbardakci Elise V. , Grilo Carlos M. 
Published: February 2024

AbstractObjectiveParental eating disorders are associated with disordered eating behaviors and psychopathology in their children, but it is not known whether parent treatment for binge‐eating disorder (BED) is associated with changes in child disordered eating behaviors and weight. Benefits or the “ripple” effect of treatment on untreated family members has been described in the obesity literature but not for BED.MethodParticipants evaluated for two randomized clinical trials for BED were screened for whether they had children. 76 parents completed baseline assessments about a school‐aged child; 62 were randomized to treatment, of whom 41 completed end‐of‐treatment assessments about their child's eating behaviors and weight (which were not targeted in the parent treatments).ResultsAnalyses revealed a significant effect of time on children's binge‐eating frequency and perceived weight category and a significant effect of parent medication on perceived weight category. Parental change in binge eating was associated significantly with changes in child secretive eating and food hoarding. Parental change in weight was not associated significantly with change in age/sex‐normed child BMI percentile, but had some associations with parent‐perceived child weight category.ConclusionsParent changes during their treatment were associated with changes in their children. Future longitudinal research is needed to examine when disordered eating emerges and clarify critical intervention timing related to children's age and parental BED. Further clinical research is also needed to assess the effectiveness of treating disordered eating at the family level.Public SignificancePrior cross‐sectional work has found that parents with BED are more likely to have children who engage in binge eating compared to parents without eating‐disorder psychopathology. This study was an initial exploration of change in children when parents received treatment in randomized controlled trials for BED. In this study, parent changes in binge eating were associated with reduced child secretive eating and food hoarding.

Published: February 2024

AbstractThe intermolecular hydroamination of norbornene with simple amines was achieved using silyl‐substituted ortho‐terphenoxide yttrium complexes. Excellent conversion was obtained for both benzylic and aliphatic amines. For benzyl and linear aliphatic amines, the highest activity was observed for the sterically more encumbered methyldiphenylsilyl‐substituted complex, whereas the trimethylsilyl‐substituted complex was more active for sterically encumbered primary amines.
Who benefits the most? Teacher expectations and their relation with students’ achievement in mathematics in primary school
Authors: Hollenstein Lena , Brühwiler Christian , König Johannes 
Published: February 2024

AbstractOver the past 50 years, many studies have investigated the impact of teacher expectations on student achievement and indicated small to moderate effects. Currently, it is still unclear which student‐related factors (e.g. socioeconomic status, or gender) moderate the expectation effect. There is still a need to gain a better understanding of the relation between teacher expectations and students' characteristics. The present study aims to examine the accuracy of teacher expectations as well as student‐related moderators of the expectation effects on students' achievement. The analyses are based on data from a longitudinal study including 28 primary school teachers and their students (N = 509). The results show that high expectations of teachers correlated positively with student achievement in mathematics, although no significant moderating effects were found. These findings strengthen the importance of ensuring high teacher expectations for all students.

Published: February 2024

AbstractActive electric‐driven droplet manipulation in digital microfluidics constitutes a promising domain owing to the unique and programmable wettability inherent in sessile ionic droplets. The coupling between the electric field and flow field enables precise control over wetting characteristics and droplet morphology. This study delves into the deformation phenomena of ionic sessile ferrofluid droplets in ambient air induced by uniform electric fields. Under the assumption of a pinned mode throughout the process, the deformation is characterized by variations in droplet height and contact angle in response to the applied electric field intensity. A numerical model is formulated to simulate the deformation dynamics of ferrofluid droplets, employing the phase field method for tracking droplet deformation. The fidelity of the numerical outcomes is assessed through the validation process, involving a comparison of droplet geometric deformations with corresponding experimental results. The impact of the electric field on the deformation of dielectric droplets is modulated by parameters such as electric field strength and droplet size. Through meticulously designed experiments, the substantial influence of both field strength and droplet size is empirically verified, elucidating the behavior of ionic sessile droplets. Considering the interplay of electric force, viscous force, and interfacial tension, the heightened field intensity is observed to effectively reduce the contact angle, augment droplet height, and intensify internal droplet flow. Under varying electric field conditions, droplets assume diverse shapes, presenting a versatile approach for microfluidic operations. The outcomes of this research hold significant guiding implications for microfluidic manipulation, droplet handling, and sensing applications.
