 2022-11-28 The Magic of Transforming Carbon Dioxide to Ethanol: An Analysis of Copper-Based Electrochemical Catalysts 點閱次數: 9
Copper electrocatalysts have been shown in the past literature to selectively reduce carbon dioxide to hydrocarbons. However, due to the lack of systematic studies on time-scale resolved spectral features, the selectivity resulted from the surface atomic characteristics of the copper catalyst– could be copper metal or copper oxide, along the reaction path remains uncertain. This study introduces an X-ray absorption spectrum with a few seconds resolution scale to observe the chemical state evolution of catalysts in reactions. Under specific experimental conditions, it was observed that the average oxidation state consisted of the mixed oxidation states on the surface of copper material could be stably maintained on the electrode surface, thus steadily increasing the effective yield of ethanol. Combined with the first-principles simulations, the catalytic reaction pathway of CO2 conversion can be derived step-by-step and verified by experimental observations.more

 2022-10-20 Quick home test for Parkinson's medication adjustment: Detection of L-DOPA in blood using enzyme colorimetry 點閱次數: 35
Parkinson's disease is a neurological disorder that primarily affects motor performance. L-DOPA is the precursor of dopamine (DA) synthesis in the body and is widely used in the treatment of Parkinson's disease. However, because of the side effects associated with these drugs, clinical adjustments to the medication are often required. Therefore, measuring the concentration of L-DOPA in patients is an issue of interest for many researchers. Several methods have been developed to detect the concentration of L-DOPA, such as electrochemical assay and liquid chromatography, but there are still some limitations. In this study, a simple enzymatic colorimetric method was developed to selectively identify and oxidize L-DOPA by oxidative enzymes, resulting in a yellow product that can be identified by the naked eye; the concentration of L-DOPA can be inferred from the color intensity. Therefore, it can be used as a quick and easy estimation of the L-DOPA concentration in the test body, which is expected to be used as an indicator and reference for drug formulation.more

 2022-09-22 Detecting the size of primordial black holes with superhorizon perturbations 點閱次數: 41
At the onset of the cosmic journey, the inflationary mechanism produced superhorizon curvature perturbations which affected the future formation of the universe. This study analyzed the growth of superhorizon curvature perturbations in the inflationary universe. Using a simple ultraslow-roll model, we derived the coherence function between any two points in the curvature perturbation. It showed that the causality limits the growth of the curvature perturbation, thereby constraining the important inflationary slow-roll parameters, allowing the universe to produce a large enough primordial black hole. Our research will help estimate how curvature perturbations form primordial black holes in the universe.more

 2022-07-25 How does genetic inheritance affect learning and memory? 點閱次數: 87
This study aims to explore how epigenetic factors affect learning and memory in academic performanc. Previous studies have shown that genetic factors affect about 60% of the variation in scientific learning (Polmin & Haworth, 2008). However, recent studies have indicated that the interaction of genes with the environment (epigenetics) may be the most important factor affecting brain development, brain plasticity, and learning behavior. Environmental factors activate intracellular signaling pathways and alter the state of epigenetic genes. Epigenetic factors affect neuroplasticity through neurophysiology, which in turn regulates learning and memory. One of the epigenetic factors, non-coding small molecule RNA (MicroRNA) is currently considered to be the primary factor regulating brain development and cognitive learning memory. The objective of this study was to explore the relationship between non-coding small molecule RNA in neural pathways related to brain plasticity, cognitive ability, and scientific learning effectiveness. In addition, this study also examined how genetic factors, including genetics and epigenetics, affect adolescent cognitive function and scientific learning memory. Discovering how learning environments interact with genetics will provide important insights into the academic and practical aspects of adaptive learning.more

 2022-07-15 Jokes for the brain: Unlock the neural mechanisms of the brain in reading different humorous materials 點閱次數: 94
Humor is a good medicine for physical and mental health, as well as an effective lubricant for interpersonal relationships. Previous functional magnetic resonance imaging (fMRI) studies have revealed the neural structure of the brain in reading humorous materials, and the different brain regions dedicated to reading and understanding different humorous materials. Based on this, Chen and Chang’s research team is the first to use event-related potentials (ERPs) to investigate the cognitive processes of different humorous materials, taking advantage of the high temporal resolution of ERPs to clarify the dynamic temporal differences in the cognitive processes of humor comprehension. The results not only enable us to understand how the brain interprets different types of humorous materials (e.g., pun jokes and semantic jokes) from the perspective of brain science, but also contribute to the integration of psychological research in Taiwan and abroad, and facilitate academic/scientific exchanges between international scholars.more

 2022-05-24 Taiwan's motorcycle waterfall spectacle poses health risks 點閱次數: 110
Motorcycles are the most common mode of transportation in Taiwan, as they are convenient and can quickly reach their destination, saving a great deal of commuting time, but is riding a motorcycle related to people's healthy lifestyle habits? Or is it related to increasing the risk of obesity? The research team of Professor Liao in the Department of Health Promotion and Health Education at National Taiwan Normal University conducted a series of analyses and discussions on this topic. The research team measured motorcycle use behavior among more than 1,000 Taiwanese adults and explored their association with healthy lifestyle habits and obesity risk. The first findings showed that “high motorcycle users” (more than 280 minutes per week) had a 1.5-fold increase in obesity risk compared with "non-motorcycle users." The second study found that Taiwanese adults who ride more than 30 minutes a day on motorcycles replace more traffic-related physical activity (such as walking and cycling). Based on the results of this study, it is suggested that health promotion programs need to be designed specifically for the motorcycle population in the future.more

 2022-04-04 Does online social anxiety using instant messaging software affect job engagement? 點閱次數: 173
In today's workplace, it is a social trend for workers to have a variety of evolving real-time communication software to help them communicate and coordinate at work. The Instant Messaging (IM) software LINE has played an important role in the trend of responding to the real-time needs of the public to improve government effectiveness. However, because of its immediacy and convenience, government workers often receive a high volume of messages. There is a lack of relevant and objective research data on the impact on civil servants’ perceived experiences of their work under such a workplace norm as a basis for promoting the use of LINE in the government sector. To address this gap, this study examined the relationship between online social anxiety, Line cognitive fatigue (LCF), perceived information overload of instant messaging (PIOIM), and job engagement among civil servants based on the media richness theory.more

 2022-03-10 Does it matter if you regret it? Using negative experience to open the door to the future 點閱次數: 140
From childhood, we were taught to strive for a life without regrets, but in reality, things often go against our wishes. Since regret is a common feeling, what is the thing we regret most in life? According to Western studies, the most regretful thing is, surprisingly, education, ranking much higher than career, love, upbringing, and security (Streep & Bernstein, 2015). Fries et al. (2005) also found that regardless of whether they had clear academic goals or not, as many as 90% of students reported experiencing confusion and conflict over course selection, which had a profound impact on their cognitive experiences and academic emotion.more

 2021-12-15 Deciphering the Morse code of communication between butterflies and ants 點閱次數: 220
It has long been known that there is a close symbiotic relationship between silverline butterflies and ants. The larvae of the silverline butterfly have honey (nectar) glands and other ant-loving (myrmecophily) organs that attract ants and increase their survival rate by being cared for by ants. The larvae secrete honeydew for the ants to feed on. It is interesting though that the pupa does not have ant-loving organs to attract ants. This phenomenon has caused scientists to wonder if there are other mechanisms by which small gray butterflies attract ants. One of the answers is the inaudible sound vibration signal, which was published in an international journal on December 6, 2019 (Scientific Reports).more

 2021-11-03 Coffee Helps Relieve Muscle Soreness Caused by Exercise, Making you Stronger 點閱次數: 160
Promoting athletic performance through nutritional supplementation has been a popular research topic in sports science, and caffeine has been proven in many studies to be a legitimate supplement that can effectively enhance aerobic and anaerobic performance. However, whether caffeine, which also has an analgesic effect, can be effective in reducing muscle strength performance when the exercise causes delayed muscle soreness in the case of supplementation, and whether the effect has gender differences, has not been clarified. Therefore, we designed an experiment in which a downhill running caused running-induced delayed muscle soreness with male and female athletes, followed by caffeine supplementation of about three cups of American coffee, and observed the degree of muscle soreness change and muscle strength performance. The results showed that caffeine supplementation was effective in terms of reducing the muscle pain of both male and female athletes, but the degree of reduction in pain was higher in men than in women. Both men and women, however, can benefit from the same supplement of coffee that reduces the maximum loss of muscle strength. If you have muscle soreness and want to exercise, drink some coffee next time.more

 2021-09-21 Transformers in The Porous Materials Field: Extremely Fast Lattice Rearrangement of the MOF Structures 點閱次數: 150
In this work, we present a case system that can achieve rapid structural rearrangement of the whole lattice of a metal–organic framework (MOF) through a ‘domino’ alteration of the bond connectivity under mild conditions. Topological transitions between significantly different phases typically require extreme conditions to collectively break chemical bonds and overcome the stress caused to the original structure by altering its correlated bond environment. Our system transforms from a disordered and less crystalline MOF with low porosity to a highly crystalline and porous isomer within few minutes upon activation (solvent exchange and desorption), resulting in a significant increase in surface area, from 725 to 2,749 m2/g. Spectroscopic measurements show that this counter-intuitive lattice rearrangement involves a metastable intermediate with defect frameworks that results from solvent removal on coordinately unsaturated metal sites. This less crystalline–crystalline switch between two topological distinct MOFs is shown to be reversible over four cycles through activation and re-immersion in polar solvents. The aim of this study was to investigate the partial defects in real MOF crystalline structures and to focus on defect-induced MOF properties, which are expected to enhance and develop the physical, mechanical, electronic and optical material properties and chemical activities of MOF materials. This research adopted an exploratory experimental procedure that facilitated the synthesis of highly porous MOFs, which were previously not easy to synthesize, and functional applications for defective and highly porous MOFs were further developed.more

 2021-07-23 Can happiness be taught? 點閱次數: 221
In order to teach students to live happily, Wellington College in England pioneered the happiness curriculum. The purpose of this article is to analyze the concept of happiness in the book "Teaching Happiness and Well-being in Schools" by Ian Morris, a representative figure of the British happiness curriculum, in order to judge whether happiness can be taught. The paper points out that Morris' perspective of happiness has undergone transformation, beginning with a direct inheritance from positive psychology, and emphasizing the adjustment of the subject's mindset. In the middle stage, he adopts Aristotle's theory of happiness in action, regarding happiness as a natural feeling and state experienced after activities by the subject. In the latter stage, it is clearly asserted that happiness is an activity according to virtue and that the happiness curriculum should be the foundation of character education. Overall, the Morris Happiness curriculum can be seen as a complex of positive psychology and Aristotle's theory of happiness. Basically, the modules of the well-being curriculum are drawn from the key themes of positive psychology at the beginning, emphasizing that students learn happiness skills that have been proven to be effective, and then changing to underline that these themes must be connected to the development of personal virtue. At this point, happiness lessons and character education become inseparable. This article concludes that happiness can be taught and needs to be taught, but that given the multiplicity of happiness, it is also necessary to examine the concept of happiness reflected in the teaching of happiness from a philosophical perspective. more
