Authors: Rillo April Love Joy A. 
Published: January 2025

The goal of this research was to describe the experiences of reading program implementers in Pudtol District, Province of Apayao as reading program implementers. Employing phenomenological approach among seven teacher participants, in-depth interview was conducted which answered the four fundamental questions. Essential themes were generated out from their responses to the research questions. The findings uncovered the participants’ lived experiences, and from it seven themes emerged: expecting students already know how to read, most students are slow readers, having a hard time implementing reading program to students, able to know the reading level of the students, able to influence students in reading, providing appropriate reading activities and able to know the learner’s capacity in reading. The participants also shared the challenges they encountered as reading program implementers, from which emerged five themes: the absenteeism of learners, learners’ lack of interest, the attendance of learners, providing time in reading implementation, and addition to workload. Further, for the coping mechanisms they revealed ten essential themes: conduct a meeting, prepared reading materials in different reading levels, peer-tutoring, providing differentiated activities, send letters to parents whose child is always absent, home visits, parents and students, students and co-teachers, ask parents to assist their child in reading, and technical assistance from co-teachers Lastly, for the insights, eight themes emerged: use appropriate reading materials, develop time management, be patient, provide more time in reading activities, provide assistance to the reading programs implementers, provide specified time and teacher for reading implementation, improvement on learners’ reading and comprehension skills, and upcoming high school students already know how to read. In view of the above, research and educational practices should continue to evolve to meet the changing needs of students in the new normal. Prioritizing early literacy interventions, continuous development of reading programs, and a coordinated effort to foster strong reading skills among students are essential steps towards a brighter educational future.

Abstract

Improving the effectiveness of conservation practice requires better use of evidence.

Since 2004, researchers from the Conservation Evidence group (University of Cambridge) have engaged with over 1100 named practitioners, policymakers, funders and other academics from across the world to identify needs and develop a range of principles, tools and resources to embed evidence in decision making. The goal of this engagement (the Conservation Evidence Programme) was to deliver improved conservation practice leading to benefits for nature and society. Together, we developed a theory of change with five key strategies for delivering change, alongside a freely available Evidence Toolkit to support decision makers in achieving that change.

The authors describe the toolkit, a collection of freely available tools and resources developed by the collaborative programme, and how co‐design, employing different levels of partner engagement, enabled its development.

Reflecting on our experiences highlighted a number of insights and recommendations, including the need to identify where deep engagement is a necessary condition for success; the importance of collective agreement of the roles of different partners; the need to consider how to facilitate uptake of new tools or practices, particularly where that requires changes to organisational practices or culture; and the importance of establishing processes/channels for ongoing engagement with stakeholders, with a willingness to be flexible and open to incorporating new suggestions and perspectives as needed.

The Conservation Evidence Programme has enabled practitioners, funders and policymakers to become part of a network of forward‐thinking organisations that is working collaboratively to help drive more effective conservation practice through improved evidence use.

ObjectiveRegular clinical assessment for complications of systemic sclerosis (SSc) such as pulmonary arterial hypertension (PAH) is essential for early institution of therapy and improved outcomes. The objective of this study was to determine the impact of COVID‐19 pandemic‐related restrictions on health care access of patients with SSc, including screening for PAH.MethodsSouth Australian and Victorian patients enrolled in the Australian Scleroderma Cohort Study were surveyed about their perceptions of the impact of the pandemic on mental well‐being, access to medications, investigations, and management of SSc. Frequency of annual rheumatology assessments, pulmonary function tests (PFT), and transthoracic echocardiography (TTE) to screen for PAH were compared with rates from before the pandemic.ResultsA total of 312 of 810 patients with SSc responded (38.5% response); 273 were female (87.5%), the median age was 64.7 years, 77.2% had limited disease, the median illness duration was 15.6 years, 15.7% were immunosuppressed, 32.1% had interstitial lung disease, and 6.4% had PAH. A total of 65.7% of consultations were by telehealth, of which 81.2% were by telephone. Compared with respondents in South Australia (n = 109), Victorian respondents (n = 203) experiencing prolonged lockdown, reported reduced access to their rheumatologist (49.3% vs 27.9%; P = 0.004), greater use of consultation by video (17.3% vs 2.1%; P = 0.008), greater health care disruption (49.0% vs 23.2%; P < 0.001), and worse mental health (P = 0.002). Respondents reported reduced access to PFT and TTE (31.7% and 22.5%, respectively). Annual visits, PFT, TTE, and new diagnoses of PAH were reduced in 2020 to 2022 compared with 2011 to 2019.ConclusionThe COVID‐19 pandemic–related disruption to health care for patients with SSc was associated with worse mental health and reduced screening and diagnosis of PAH, which may impact long‐term outcomes.

AbstractWeak‐light imaging holds immense significance in various imaging applications. Recently, there has been significant research focused on 2D perovskites for photodetectors (PDs), owing to their superior photoelectric properties. However, the utilization of 2D perovskites for high‐performance weak‐light detection remains limited, and there is a notable absence of demonstration in weak‐light ultraviolet (UV) imaging. Herein, a high‐sensitive UV detectors with an ultra‐low detection limit for weak‐light imaging are demonstrated, utilizing 2D perovskite (PA)2PbBr4 (PPB) single crystals (SCs). Leveraging the exceptional quality of SCs, the PPB‐based PD exhibits outstanding operational performances, including a low dark current of 0.735 pA, high on/off ratio of 4150 under 263.3 mW cm−2 illimitation, and extensive linear dynamic range of 153.61 dB, which is currently the highest reported value among 2D perovskite SC detectors. Notably, PPB PDs demonstrate a remarkable response under 5.49 nW cm−2 illumination, enabling it to exhibit outstanding photo‐response with an excellent detectivity of 2.3 × 1013 Jones and responsivity of 2.22 A W−1. Importantly, high‐resolution images are successfully obtained under weak‐light illumination. These findings underscore the immense potential of 2D perovskite for UV weak‐light imaging.

AbstractAcross diverse natural surfaces, remarkable interfacial functionalities emerge from micro and nanoscale self‐assemblies of wax components. The chemical composition of the epicuticular wax prescribes the intrinsic crystal morphology and resultant topography of the natural surfaces, dictating their interfacial wetting properties. The potential of regulating the topography of identical wax compositions through various crystallization routes is tested here. Crystallization through solvent evaporation produces diverse topographies with enhanced surface hydrophobicity compared to the slow cooling of the wax melt. Further, the microscale interfacial crystalline structure can be deliberately designed to operate in sticky or slippery hydrophobic regimes through control of the supersaturation level during the crystallization process. While the supersaturation level significantly impacts surface wettability by modulating the microscopic aggregation of rice bran wax crystals, the crystal structure at the molecular scale remains effectively unchanged. The relationships between the supersaturation level, surface topography and hydrophobicity modes, primarily derived for rice bran wax, are qualitatively validated for a wider range of plant‐based waxes. Crystallization of inherently hydrophobic plant‐based waxes from thermodynamically isotropic solutions offers an affordable single‐step approach for the fabrication of biodegradable hydrophobic coatings, applicable to versatile materials and geometries.

Abstract2D intercalated vanadium chalcogenides have attracted intensive interest based on their physical properties and potential applications. However, controllable synthesis of the intercalated vanadium chalcogenides via chemical vapor deposition is still a big challenge. Here, a binary metal precursor co‐reaction growth mechanism to manipulate the evaporation rate of vanadium precursors is reported, thus the intercalated 2D V1+XS2 – V3S5 single crystal can be controllably synthesized. The quality of 2D V3S5 nanosheets is identified by Raman spectroscopy and high‐resolution scanning transmission electron microscopy. Interestingly, a phase transition in 2D metallic V3S5 nanosheets is observed at 20 K. Meanwhile, the resistance upturn and unsaturated negative magnetoresistance induced by electron–electron interaction is confirmed. This work proposes a new strategy to synthesize the 2D intercalated VxSy single crystals with different compositions for studying their excellent properties and potential applications.

AbstractA series of high‐symmetry Th6–metal‐organic frameworks (MOFs) are constructed using various metal complex units and the thorium (Th) cluster, and then being applied as a well‐defined catalyst model in the photocatalytic oxidation of methyl phenyl sulfide reactions. The integration of Th6‐MOFs by incorporating metal complex units and redox sites (Th6 cluster and single‐metal site) can effectively modulate the conversion rate and selectivity. Among them, Ni–PBA–Th6 (PBA = 4‐pyridin‐4‐yl benzoic acid) achieves up to ≈99% conversion and ≈97% selectivity for methyl phenyl sulfone. Experiments and theoretical calculations further elucidate that Th6 cluster is the catalytic site for the oxidation of methyl phenyl sulfide to methyl phenyl sulfone, while Ni–PBA is the catalytic site for the reduction of hydrogen peroxide. This work sheds new insight into the structural design and photocatalytic application of more efficient thorium‐based MOF catalysts.

Published: September 2023

AbstractAqueous zinc‐ion batteries (AZIBs) offer promising prospects for large‐scale energy storage due to their inherent abundance and safety features. However, the growth of zinc dendrites remains a primary obstacle to the practical industrialization of AZIBs, especially under harsh conditions of high current densities and elevated temperatures. To address this issue, a Janus separator with an exceptionally ultrathin thickness of 29 µm is developed. This Janus separator features the bacterial cellulose (BC) layer on one side and Ag nanowires/bacterial cellulose (AgNWs/BC) layer on the other side. High zincophilic property and excellent electric/thermal conductivity of AgNWs make them ideal for serving as an ion pump to accelerate Zn2+ transport in the electrolyte, resulting in greatly improved Zn2+ conductivity, deposition of homogeneous Zn nuclei, and dendrite‐free Zn. Consequently, the Zn||Zn symmetrical cells with the Janus separator exhibit a stable cycle life of over 1000 h under 80 mA cm−2 and are sustained for over 600 h at 10 mA cm−2 under 50 °C. Further, the Janus separator enables excellent cycling stability in AZIBs, aqueous zinc‐ion capacitors (AZICs), and scaled‐up flexible soft‐packaged batteries. This study demonstrates the potential of functional separators in promoting the application of aqueous zinc batteries, particularly under harsh conditions.

AbstractDehydrochlorination of 1,3‐dichloropropanol with alkali is a key step to industrially produce epichlorohydrin. But there are many side reactions involved in the synthesis process. In this work, a complete mechanism and kinetics investigation of the related reaction network was constructed. Density functional theory simulation method was first used to simulate the possible reactions so as to confirm the reaction mechanism and simplify the reaction network. Based on the simulation results, the complex reaction network was simplified into a three‐step consecutive reaction. The kinetic parameters of the three consecutive steps, including the order of the reaction, the pre‐exponential factor, and activation energy, were experimentally determined by conductance and other methods. All the experimental results are basically consistent with the simulation. The obtained kinetics data provide a basis for epichlorohydrin synthesis process optimization.

Propagation Characteristics of a Partially Coherent Gaussian Schell‐model Array Vortex Beam in the Joint Turbulence Effect of a Jet Engine and Atmosphere

Published: September 2023

AbstractThis work investigates the joint effects of jet engine exhaust‐induced turbulence and atmospheric turbulence on the propagation of a partially coherent Gaussian Schell‐model Array (GSMA) vortex beam. Using the two‐process propagation method, analytical formulae are derived for the cross‐spectral density, spectral density, degree of coherence, and beam width of the considered beam. The results show that the considered beam takes different shapes; when the spatial coherence is large, the spectral density of the GSMA vortex beam takes an elliptical shape, whereas when the spatial coherence is smaller, the spectral density remains a Gaussian shape. The evolution profile of the degree of coherence weakens gradually when the propagation distance, topological charge, and turbulence strength increase. Moreover, the profile of the degree of coherence takes the Gaussian profile when the propagation distance is longer or turbulence atmospheric is stronger. Furthermore, the results reveal that the corresponding beam spreads faster with a larger propagation distance, lower spatial coherence, and high‐strength turbulence. This study also concludes from the results that the beam is affected more when its propagation is near the jet engine exhaust, which means that this latter has a significant impact.

Published: September 2023

AbstractRegenerated silk fibroin is a promising bio‐material because of its sustainability, biocompatibility, degradability, and eco‐friendliness. However, silk fibroin hydrogel's intrinsic hard and brittle mechanical properties hinder its application on human skin as a wearable sensor. We used polypropylene glycol (PPG) as a plasticizer to physically blend with a silk fibroin solution, and designed a set of green and environmentally friendly preparation methods without organic solvents to obtain the hydrogel for wearable sensors. PPG molecules will aggregate into clusters to act as a plasticizer. Meanwhile, a large number of hydrogen bonds are formed between the hydroxyl groups in PPG and silk fibroin molecular chains. When the hydrogel is stretched, the hydrogen bond in the silk fibroin chain will release heat in an irreversible form to increase the toughness. The PPG/silk fibroin hydrogel exhibits mechanical strength of 16.6 MPa, breaking elongation of 160%, and toughness of 17.7 MJ/m3. The Ca2+ introduced during the sample preparation process gives the hydrogel ionic conductivity, which provides the possibility of using the hydrogel as a human skin sensing material.

AbstractHydrophobization of hydrophilic jute fiber, is of great importance as it can expand the applications of jute fiber in many fields. This work reports the hydrophobization of jute fiber by high‐energy radiation treatment which is an easy, single‐step, economical, and environment friendly method. Surface wettability of hydrophilic jute fiber is tuned by attaching long chain hydrocarbon molecules, namely butyl methacrylate, octyl acrylate and lauryl methacrylate, using gamma radiation. Lauryl methacrylate is found to be the most suitable agent among the molecules used for generating desired extent of hydrophobicity. Important reaction parameters, namely total dose, dose rate, monomer concentration, and solvent composition are optimized to achieve the desired degree of modification, for imparting hydrophobicity. Mechanical and thermal analysis reveals that there is no considerable damage to the base structure of fibers during modification. Scanning electron microscopy (SEM) is supporting evidence of the intactness of fiber after modification. The successful grafting of jute fiber has also been evidenced by SEM. This lauryl methacrylate modified jute can separate oily toxic liquids from aqueous media. The modified jute fiber may get enhanced applications in various fields.

Published: September 2023

AbstractIn the present work, treatability studies were carried out with oil refinery wastewater (effluent from the secondary treatment) using electrooxidation (EO) process employing two mixed oxide anodes: SnO2–RuO2–IrO2|Ti and IrO2–Ta2O5|Ti. Both electrodes' performance were compared by their capacity to generate active chlorine in a synthetic solution and organic matter mineralization of a sample with an average phenol (C6H6O) concentration of 100 mg L−1. Before degradation experiments, surface analysis, and linear sweep voltammetry tests were performed. SnO2–RuO2–IrO2|Ti anode yielded higher active chlorine, reaching an average concentration of 340 mg L−1 at 90 min of electrolysis and 25 mA cm−2. On the other hand, IrO2–Ta2O5|Ti anode only generated an average concentration of 200 mg L−1 at 90 min and 40 mA cm−2. Regarding the degradation experiments, SnO2–RuO2–IrO2|Ti anode showed the highest dissolved organic carbon removal, ranging from 26% to 40%. In addition, through a three‐dimensional excitation–emission matrix fluorescence analysis, it was possible to elucidate the degradation of C6H6O and some possible polycyclic aromatic hydrocarbons present in the effluent. The results suggested that 65%–90% of the hydrocarbons and C6H6O present in the effluent were degraded with the SnO2–RuO2–IrO2|Ti anode applying 25 mA cm−2 within the first 30 min of electrolysis, reaching almost 99% degradation at 90 min. The EO process using SnO2–RuO2–IrO2|Ti can be an alternative for tertiary treatment of oil refinery wastewater for degradation and mineralization of the remaining organic matter of secondary effluents (biological processes) via active chlorine species.
