Sense of relatedness and science engagement among Filipino high school students
Authors: Datu Jesus Alfonso D. , Noltemeyer Amity 
Published: May 2024

AbstractPast studies indicate that feeling related to specific social agents such as parents, teachers, and peers can facilitate domain‐general academic engagement. However, there is scarce research on how relatedness may be associated with engagement in specific academic subjects. This cross‐sectional study explores the associations of sense of relatedness to mother, father, science teachers, friends, classmates, and neighbors with behavioral, cognitive, emotional, and social engagement in science. Four hundred and thirty‐eight high school students completed an online survey that included scales to assess demographic information, relatedness, and science engagement. Only relatedness to science teacher positively predicted behavioral, cognitive, and emotional engagement in science when controlling for other relatedness dimensions, age, gender, year in school, parental educational attainment, and daily allowance. Although further research that can uncover causal conclusions is needed, these findings suggest the importance of science teacher relatedness for students' science engagement.

Published: May 2024

AbstractAeromonas hydrophila, a prevalent pathogen in the aquaculture industry, poses significant challenges due to its drug‐resistant strains. Moreover, residues of antibiotics like streptomycin, extensively employed in aquaculture settings, drive selective bacterial evolution, leading to the progressive development of resistance to this agent. However, the underlying mechanism of its intrinsic adaptation to antibiotics remains elusive. Here, we employed a quantitative proteomics approach to investigate the differences in protein expression between A. hydrophila under streptomycin (SM) stress and nonstress conditions. Notably, bioinformatics analysis unveiled the potential involvement of metal pathways, including metal cluster binding, iron‐sulfur cluster binding, and transition metal ion binding, in influencing A. hydrophila’s resistance to SM. Furthermore, we evaluated the sensitivity of eight gene deletion strains related to streptomycin and observed the potential roles of petA and AHA_4705 in SM resistance. Collectively, our findings enhance the understanding of A. hydrophila’s response behavior to streptomycin stress and shed light on its intrinsic adaptation mechanism.

Published: May 2024

AbstractObjectiveColorectal cancer (CRC) incidence is rising among adults under the age of 50 (early‐ or young‐onset CRC). This population is more likely to have advanced‐stage disease at diagnosis, suggesting their diagnostic pathway may be prolonged. To better understand factors influencing this pathway, this study explored patients' experiences of decision‐making during a diagnosis of young‐onset CRC.MethodsSemi‐structured interviews were conducted with 17 participants with young‐onset CRC diagnosed in 2021–2022 in Victoria, Australia. Interviews were conducted online or by phone an average 7 months (range 1–13) after diagnosis. Analysis was approached from a critical realist perspective, with themes developed inductively using reflexive thematic analysis.ResultsFive themes were identified: Shifting Perception of Urgency, Multidimensional Perception of Role, Making the Most of Resources, Stage of Life, and COVID Adds Complexity. Participants' decision‐making evolved over the diagnostic period. As participants perceived urgency to act, they took on a more active role in decision‐making, utilising personal resources to access timely care. Their decisions were shaped by stage‐of‐life considerations, including employment and caring for a young family, with the COVID‐19 pandemic adding “…a whole other layer of complexity” to the process.ConclusionsYounger adults with CRC make decisions in the context of unique considerations, adapting to reduce time to diagnosis, with decisions complicated by the COVID‐19 pandemic. Greater support from health care providers/systems in the diagnostic period may improve timeliness of CRC diagnosis and outcomes in younger adults.
Curcumin and its anti‐colorectal cancer potential: From mechanisms of action to autophagy

Published: May 2024

AbstractColorectal cancer (CRC) development and progression, one of the most common cancers globally, is supported by specific mechanisms to escape cell death despite chemotherapy, including cellular autophagy. Autophagy is an evolutionarily highly conserved degradation pathway involved in a variety of cellular processes, such as the maintenance of cellular homeostasis and clearance of foreign bodies, and its imbalance is associated with many diseases. However, the role of autophagy in CRC progression remains controversial, as it has a dual function, affecting either cell death or survival, and is associated with cellular senescence in tumor therapy. Indeed, numerous data have been presented that autophagy in cancers serves as an alternative to cell apoptosis when the latter is ineffective or in apoptosis‐resistant cells, which is why it is also referred to as programmed cell death type II. Curcumin, one of the active constituents of Curcuma longa, has great potential to combat CRC by influencing various cellular signaling pathways and epigenetic regulation in a safe and cost‐effective approach. This review discusses the efficacy of curcumin against CRC in vitro and in vivo, particularly its modulation of autophagy and apoptosis in various cellular pathways. While clinical studies have assessed the potential of curcumin in cancer prevention and treatment, none have specifically examined its role in autophagy. Nonetheless, we offer an overview of potential correlations to support the use of this polyphenol as a prophylactic or co‐therapeutic agent in CRC.

AbstractBackgroundPrior research has identified associations between pregnancy complications and specific genetic diagnoses in offspring.ObjectiveThe purpose of this study is to provide a broader investigation of associations between infant genetic diagnoses and pregnancy complications.MethodsRetrospective chart review of birthing parent–infant dyads born at Duke University (2013–2021) identified 236 birthing parents who had infants postnatally diagnosed with genetic diseases (exposed group) and 472 matched dyads without concern for newborn genetic disease (unexposed group). Logistic regression examined associations between pregnancy complications and genetic diseases in offspring.ResultsThe risk of gestational diabetes was elevated among birthing parents of infants with aneuploidy (risk ratio [RR] = 1.63; 95% confidence interval [CI]: 1.02, 2.59) when controlled for birthing parent age. The risk of pre‐eclampsia was elevated among birthing parents of infants with imprinting conditions (RR = 3.31; 95% CI: 1.29, 8.49) when controlled for birthing parent age. The presence of any infant genetic disease was associated with an increase in placental disorders (RR = 1.98; 95% CI: 1.61, 2.43), including a 2.25‐fold increase in placental infarction (RR = 2.25; 95% CI 1.72, 2.93).ConclusionsThese findings provide additional evidence into relationships between genetic diseases in offspring and pregnancy complications in birthing parents and may guide identification of pregnancies that would benefit from expanded prenatal and antenatal genetic screening for earlier identification and treatment of genetic conditions.
When help is not wanted: Frustrated needs and poor after‐work recovery as consequences of unwanted help at work

Published: May 2024

AbstractInstrumental help and support in the workplace are mostly associated with outcomes that are considered desirable for organisations and their employees. In this study, we seek to shed light on a specific type of help at work that may entail negative consequences: being offered help that is not wanted by the recipient. Drawing on basic psychological needs theory and on theory of ruminative thoughts, we propose that offering unwanted help frustrates the recipient's psychological needs for autonomy and competence, which in turn affects after‐work recovery processes in the form of increased rumination and decreased psychological detachment. Supporting our hypotheses, a cross‐sectional survey study (Study 1, N = 279) revealed that employees who were offered unwanted help from coworkers or supervisors experienced higher frustration in need for competence and autonomy, which in turn was associated with higher rumination after work and less psychological detachment from work. Results from a time‐lagged survey with two measurement points 2 weeks apart (Study 2, N = 165) showed that being offered unwanted help was concurrently related to increased competence and autonomy frustration, of which only autonomy frustration later translated into higher after‐work rumination and ultimately lower psychological detachment from work. Our findings suggest that needs frustration provides a promising approach to investigate and explain potentially detrimental effects of unwanted help at work on after‐work recovery processes.

AbstractColloidal quantum dots are semiconductor nanocrystals endowed with unique optoelectronic properties. A major challenge to the field is the lack of methods for synthesizing quantum dots exhibit strong photo‐response in the deep‐ultraviolet (DUV) band. Here, a facile solution‐processed method is presented for synthesizing ultrawide bandgap aluminium nitride quantum dots (AlN QDs) showing distinguished UV‐B photoluminescence. Combined with the strong optical response in solar blind band, a solution‐processed, self‐powered AlN‐QDs/β‐Ga2O3 solar‐blind photodetector is demonstrated. The photodetector is characterized with a high responsivity of 1.6 mA W−1 under 0 V bias and specific detectivity 7.60 × 10−11 Jones under 5 V bias voltage with good solar blind selectivity. Given the solution‐processed capability of the devices and extraordinary properties of AlN QDs, this study anticipates the utilization of AlN QDs will open up unique opportunities for cost‐effective industrial production of high‐performance DUV optoelectronics for large‐scale applications.

Published: May 2024

AbstractTransparent flexible energy storage devices are limited by the trade‐off among flexibility, transparency, and charge storage capability of their electrode materials. Conductive polymers are intrinsically flexible, but limited by small capacitance. Pseudocapacitive MXene provides high capacitance, yet their opaque and brittle nature hinders their flexibility and transparency. Herein, the development of synergistically interacting conductive polymer Ti3C2Tx MXene/PEDOT:PSS composites is reported for transparent flexible all‐solid‐state supercapacitors, with an outstanding areal capacitance of 3.1 mF cm−2, a high optical transparency of 61.6%, and excellent flexibility and durability. The high capacitance and high transparency of the devices stem from the uniform and thorough blending of PEDOT:PSS and Ti3C2Tx, which is associated with the formation of O─H…O H‐bonds in the composites. The conductive MXene/polymer composite electrodes demonstrate a rational means to achieve high‐capacity, transparent and flexible supercapacitors in an easy and scalable manner.

Published: May 2024

AbstractAlong with an ever‐deepening understanding of the catalytic principle of natural enzymes, the rational design of high‐activity biomimetic nanozymes has become a hot topic in current research. Inspired by the active centers of natural enzymes consisting of catalytic sites and binding pockets, a Cu‐doped CoS2 hollow nanocube (Cu/CoS2 HNCs) nanozyme integrating substitution defects and vacancies is developed through a defect engineering strategy. It is shown that the vacancies and substitution defects in the developed Cu/CoS2 HNC nanozymes serve as binding pockets and catalytic sites, respectively. The construction of this key active center and the accelerated electron transfer from the Co/Cu redox cycle significantly improve the substrate affinity and catalytic efficiency of the Cu/CoS2 HNCs nanozymes, which results in the excellent catalytic performance of the Cu/CoS2 HNC nanozymes. Using the superior enzymatic activity of Cu/CoS2 HNCs, a fluorescence detection platform for alkaline phosphatase (ALP) is established, which is a wider detection range and lower limit of detection (LOD) than previous work. This work broadens the family of nanozymes and provide a new idea for the development of novel nanozymes with high enzyme activity, as well as a guideline for the construction of highly sensitive fluorescent sensors.

AbstractThe formation of a stable solid electrolyte interphase (SEI) layer is crucial for enhancing the safety and lifespan of Li metal batteries. Fundamentally, a homogeneous Li+ behavior by controlling the chemical reaction at the anode/electrolyte interface is the key to establishing a stable SEI layer. However, due to the highly reactive nature of Li metal anodes (LMAs), controlling the movement of Li+ at the anode/electrolyte interface remains challenging. Here, an advanced approach is proposed for coating a sacrificial layer called fluorinated self‐assembled monolayer (FSL) on a boehmite‐coated polyethylene (BPE) separator to form a stable SEI layer. By leveraging the strong affinity between the fluorine functional group and Li+, the rapid formation of a LiF‐rich SEI layer in the cell production and early cycling stage is facilitated. This initial stable SEI formation promotes the subsequent homogeneous Li+ flux, thereby improving the LMA stability and yielding an enhanced battery lifespan. Further, the mechanism behind the stable SEI layer generation by controlling the Li+ dynamics through the FSL‐treated BPE separator is comprehensively verified. Overall, this research offers significant contributions to the energy storage field by addressing challenges associated with LMAs, thus highlighting the importance of interfacial control in achieving a stable SEI layer.

Published: May 2024

AbstractThe pursuit of high energy densities propels the design of next‐generation nickel‐based layered oxide cathodes. The utilization of low‐cobalt, ultrahigh‐nickel layered oxide cathodes, and the extension of operating voltages promise enhanced energy density. However, stability and safety face challenges associated with nickel content, including structural degradation, lattice oxygen evolution, and thermal instability. In this study, a promising strategy of Al and Nb dual‐bulk‐doping is presented in high‐Ni cathode materials of LiNi0.96Co0.04O2 (NC) to stabilize the bulk structure, suppress oxygen release, and attain superior electrochemical performance at high voltages. The introduction of Al and Nb effectively raises the migration energy of Ni2+ into Li sites and stabilizes lattice oxygen through strengthened Al─O and Nb─O bonds. Furthermore, the substitution of high‐valence Nb ions reduces the charge depletion of lattice oxygen and induces an ordered microstructure. The Al and Nb dual‐bulk‐doping strategy mitigates strain and stress associated with the H2↔H3 phase transition, reducing the generation and propagation of microcracks. The resulting Li(Ni0.96Co0.04)0.985Al0.01Nb0.005O2 (NCAN) cathode exhibits superior cycling stability, with a capacity retention of 77.8% after 300 cycles, even when operating at a high‐voltage of 4.4 V, outperforming the NC (48.5%). This work provides a promising perspective for developing high‐voltage and high‐Ni cathode materials.

AbstractDie Entwicklung und der rasante Ausbau des Eisenbahnnetzes seit der Mitte des 19. Jahrhunderts kann als maßgeblicher Bestandteil der Industrialisierung in Deutschland bezeichnet werden, hatte massive Auswirkungen auf die Siedlungs‐ und Landschaftsplanung und griff dadurch tief in die kulturhistorische Entwicklung der jeweiligen Region ein. Als Folge der Hochindustrialisierung stiegen um 1900 der Wunsch der Bevölkerung nach Mobilität sowie die Notwendigkeit des Transports von Waren enorm an, sodass das Eisenbahnnetz immer stärker ausgebaut wurde. Insbesondere im städtischen Bereich ging damit auch der Bau einer umfangreichen Infrastruktur einher, die sowohl auf der Straße als auch auf der Schiene schnell an ihre Kapazitätsgrenzen geriet. Die dafür notwendigen Gleisumlegungen machten eine große Anzahl von neuen Brückenbauwerken erforderlich. So entstand eine Vielzahl von stählernen Vollwandträgerbrücken mit geringer Spannweite, die mit ihrer ökonomischen Formensprache und reich gestalteten Pylonen an den Widerlagern die Städte nachhaltig veränderten. Diese Brückenensembles sowie die jeweiligen Bau‐ und Planungsprozesse werden für die Städte Hannover und Chemnitz in diesem Aufsatz näher betrachtet und es soll diskutiert werden, welche Lösungen für die gleiche Bauaufgabe vor dem jeweiligen regionalen und politischen Hintergrund gefunden wurden und wie diese das Stadtbild prägen.

Published: May 2024

AbstractThis study was aim to optimize the formulation of the sodium alginate biosensor substrate with incorporation of sodium alginate (1%‐6%(w/v)) as a polymer backbone and glycerol (10–50 wt%) as a plasticizer. The effect of their interaction on film's tensile strength (TS) and elongation at break (EB) were analyzed via response surface methodology‐central composite design (RSM‐CCD). The optimum parameter of the films for the maximum TS was at 1.90%(w/v) of sodium alginate and 17 wt% of glycerol and for maximum EB was at 4.89%(w/v) of sodium alginate and 49.65 wt% of glycerol. The optimum parameter of the films had revealed the better TS was at lower sodium alginate content and better EB was at higher glycerol content. In terms of thermal stability, the thermal decomposition temperature (Tonset) of sodium alginate decreased with the incorporation of glycerol.

AbstractEven though ceramic foam filters for metal melt filtration have been used in the casting industry for many decades, the filtration mechanisms have not yet been satisfactorily determined. Due to the opaqueness of the melt and the need for high operating temperatures as well as the complexity of the aluminum casting process, filtration experiments are expensive and a detailed insight into the filtration process is hardly achievable. However, the analysis by means of a model system contributes to an essential understanding of the processes taking place. Metal melt systems are characterized by their high surface tension resulting in poor wettability of the solid surfaces in contact with the liquid melt. Therefore, the model system needs to exhibit both similar flow characteristics and wetting properties as the melt system to obtain reliable results. In this study, water was used as the model liquid and the wetting properties of the solid surfaces have been modified to mimic the characteristic wetting behavior of the melt-filter interface. The influence of filter and particle properties as well as process parameters on the filtration efficiency of ceramic foam filters have been investigated. In order to minimize possible overlapping effects in the determination of individual parameters influencing the separation efficiency, care was taken to vary only one parameter, so that the filtration is only dependent on one variable. Besides water-based filtration experiments, it is also possible to have a closer look on interaction forces between inclusion particles and the filter wall and how a higher filtration efficiency can be achieved. Here, too, a water-based model system is beneficial due to the same issues of available devices and costs.

Published: May 2024

AbstractThis chapter contains a summary of thermodynamic investigations of ceramic filters, metal melts and their interaction, which can serve as a basis for the optimization of the filters as well as the casting and metal melt filtration process. First, the thermophysical properties of two different filter base materials are briefly discussed. Subsequently, after demonstrating measurement conditions and parameters, the effective thermal conductivities of filters with varying pore size, porosity and material measured by the Transient-Plane-Source method at temperatures up to 700 °C are presented. The experimental determination of radiative properties of the filters using a Fourier-transform infrared spectrometer with an external integrating sphere was compared to simple predictive methods. Finally, after performing experiments with air, a measurement section was created and further developed to determine the volumetric heat transfer coefficient during metal melt filtration. The first results obtained with aluminum melt are presented.In addition to the knowledge of heat transport processes, the understanding of the sorption and diffusion behavior of various gases in metal melts is important. Therefore, a thermogravimetric apparatus, which enables the direct determination of the mass changes caused by (ab-)sorption using a high-precision magnetic suspension balance, was modified especially for this measurement task.
