Authors: Prudente Josephine , Yunaningsih Ani 
Published: September 2023

In its quest for quality education, Higher Education Institutions (HEI) ascribed to the UN's SDG 4 Quality Education in ensuring that inclusive and equitable quality education will promote lifelong learning and opportunities for all. The critical role of Higher Education Institutions (HEIs) in building teaching skills, fostering knowledge, and engagement with society are significant factors in developing its human resources, particularly, the faculty. The benefits and challenges brought about by Industry 4.0 drive the universities to integrate quality education into their mission of promoting positive change, lifelong learning, and competitiveness. The study utilized qualitative and descriptive design to probe the variabilities and similarities of Human Resource Development strategies, quality education initiatives, and university competitiveness of HEIs in Bandung and Manila. Thematic analysis was carried out to produce more conclusive results. The researchers applied a data condensation process to form a perceived relevant category and a theme was created based on strategies and competitiveness. The significant result shows a deficit in the strategy to target specific faculty KSAs in the personal development in-service programs instituted by the HEIs in Manila. Remarkable are the many organizational strategies employed by both cities that yields quality education indicator (management) particularly the essential role of the HEI in instituting policies for faculty’s wholistic development. Results on competitiveness denote compliance to most functional capacities of both cities as a valuable means of mobility as the education workers meet the demands of their job. Moreover, the strong partnership with local and international agencies solidifies various developmental programs and the social relevance of the university. The study recommends further study on the impact of the educational global ranking system in the retention of human resources and employment of graduates.

The current study explored the impact of instructional technology on the improvement of speaking skills for first-year students at Integrated Polytechnic Regional College Kitabi. It included both qualitative and quantitative methodologies, and a sample of 132 respondents was chosen using purposive and census methods. SPSS was used to analyze the data that was gathered through interviews and questionnaires.
The study found that students as well as lecturers have positive mindset toward using ICT as a tool to improve English-speaking skills. It proved that using the pertinent instructional technologies to help students and lecturers enhance their speaking skills was beneficial. Conversely, the study identified some challenges that hamper the efficient use of these technological tools. It revealed that students face a variety of hurdles, including not having personal technological gadgets to utilize wherever and whenever they wish and a lack of enough ICT facilities at the college. Therefore, this study postulates that English language lecturers should effectively use ICT as a teaching tool to develop their English-speaking abilities, and the college authorities should consider the importance of ICT as a teaching and learning tool and increase ICT infrastructure to serve this purpose.
La pédagogie des sans-terre comme forme d’expérience et d’enracinement démocratique du travail
Authors: Devette Pascale , Furukawa Marques Dan 
Published: September 2023

Cet article interroge les liens entre éducation, démocratie et travail tels qu’ils se déploient dans une école du Mouvement des travailleurs ruraux sans-terre (MST) du Brésil, afin de cerner la manière dont ces trois sphères sociales s’influencent mutuellement. Pour ce faire, nous analysons les pensées de John Dewey (1859-1952) et de Simone Weil (1909-1943), indirectement mobilisées par les sans-terre pour créer ce qu’ils appellent la « pédagogie de la campagne », soit une praxis démocratique qui articule éducation et travail et qu’ils appliquent dans des centaines d’écoles à travers le Brésil. Nous partirons d’abord de considérations théoriques, afin de montrer l’importance sociale et politique de réfléchir à des institutions qui favorisent les capacités d’attention pour comprendre en retour comment ces capacités, loin d’être purement individuelles, ont des effets sur la qualité des liens sociaux et de la vie collective. Cette vision de l’articulation entre démocratie, éducation et travail à travers l’attention se retrouve au coeur de plusieurs institutions d’éducation gérées par le Mouvement des sans-terre au Brésil.

Abstractℤ‐classified higher‐order topological insulators (HOTIs) with chiral‐symmetric higher‐order topological phases protected by multipole chiral numbers (MCNs) have attracted extensive interest recently. However, how to design artificial ℤ‐classified HOTIs with multiple topological phases remains an unresolved issue. Here, multiorbital degrees of freedom are introduced to acoustic crystals and the various methods of topological phase transitions are achieved for the orbital ℤ‐classified HOTIs. Experimental results demonstrate the realization the coexistence of corner modes with distinct mechanisms within one single model. This provides a pathway for finding ℤ‐classified with large MCNs independent of long‐range coupling. Additionally, a universal approach is introduced here to fabricate topological bound states in the continuum derived from the discrepant onsite energy of degenerate p‐orbitals. These findings provide new insights into the study of topological wave physics using orbital degrees of freedom and may pave the way for designing innovative orbital topological devices for sensing and computing.

Published: January 2025

AbstractElectrochemical CO2 reduction in acidic media attracts extensive research attention due to its potential in increasing carbon efficiency. In most reports, alkali cations are introduced to suppress hydrogen evolution and to promote CO2 reduction. However, the mass transport of alkali cations through cation exchange membrane induces the change of electrolyte compositions. Herein, the variation of electrolyte compositions and the flow of carbon during CO2 reduction are analyzed quantitatively by simulation and experiments. If the initial amount of alkali cations in the anolyte is higher than the initial amount of H+ in the catholyte, the pH of the catholyte increases remarkably in long‐term CO2 reduction electrolysis, resulting in the decrease of carbon efficiency. Bicarbonate salt precipitation on the cathode with alkali cation‐containing catholyte is another origin of the decrease of CO2 reduction Faradaic efficiency and carbon efficiency. To maintain high carbon efficiency, the electrolyte should contain low concentration of alkali cations or even be free of alkali cations. Decorating the catalyst of cathode with ionomer with high density of cation sites enables CO2 reduction in pure acid solution, achieving 30‐h stable carbon efficiency.

Published: January 2025

AbstractWireless, passive, and flexible strain sensors can transform structural health monitoring across various applications by eliminating the need for wired connections and active power sources. Such sensors offer the dual benefits of operational simplicity and high‐function adaptability. Herein, a novel wireless sensor is fabricated using radio frequency (RF) technology for passive, wireless measurement of mechanical strains. Previously introduced concept of coupling piezoresistive electrodes is utilized with capacitive sensors to ensure high‐sensitivity capacitive sensing. For the first time, it is implemented and demonstrated here as a fully printable, inexpensive, and ready‐to‐use device utilizing the recent advances in piezoresistive inks and screen‐printing technologies. The near‐field communication (NFC) tag features an inductor ‐ capacitor (LC) resonant circuit with a distinct resonant frequency. The sensor exhibits high sensitivity and detects substantial variations in capacitance, with a gauge factor (GF) of ≈16 at 20 MHz for strain levels below 5%. Within the wireless framework, the sensor achieves a significant shift in resonance frequency (GF of ≈2.2). It also exhibited excellent performance in wirelessly monitoring the strain in a glass fiber‐reinforced polymer (GFRP) specimen during the bending test. The results confirm the potential applicability of the sensor as an embedded sensor for monitoring various types of composite structures. This confirms the potential of the sensor for use in composite structures as an embedded sensor.

ABSTRACTObjectivesCertain group‐living mammals—including many primates—exhibit affiliative relationships between sexes that persist past copulation. Relationships between females and males in baboons (Papio sp.) are particularly well‐characterized. These relationships tend to revolve around the female reproductive cycle and are generally female‐initiated and female‐maintained. Kinda baboons (P. kindae) appear to diverge phylogenetically and behaviorally from other baboons. Here, we assess how Kinda baboons differ socially by characterizing female–male relationships using 9 years of data on a population in Kasanka National Park, Zambia.MethodsWe used generalized linear mixed models to assess grooming rates and directionality for individuals and among female/male dyads, patterns of between‐sex proximity, and rates of agonistic behavior. We examined these patterns across female reproductive states and evaluated the degree to which dyadic affiliations persisted over time.ResultsWe find that female–male relationships in Kinda baboons are characterized by a high degree of male investment with low aggression that persists across female reproductive states and years. We find that females have strong affiliations with a single male while males have strong affiliations with multiple females at a time. Males are largely responsible for initiation, grooming, and proximity in affiliative relationships with females, and dyads often persist across years.DiscussionOur results suggest that Kinda baboons represent a mosaic of baboon social features and, paired with recent genomic evidence about their population history, may resemble the ancestral baboon phenotype. This expands our understanding of the “baboon model” for comparative socioecology and emphasizes the high variability and evolvability of social phenotypes.

Published: January 2025

AbstractThe precise and rapid extraction of lithium from salt‐lake brines is critical to meeting the global demand for lithium resources. However, it remains a major challenge to design ion‐transport membranes with accurate recognition and fast transport path for the target ion. Here, we report a triazine covalent organic framework (COF) membrane with high resolution for Li+ and Mg2+ that enables fast Li+ transport while almost completely inhibiting Mg2+ permeation. The remarkably high rejection of Mg2+ by the COF membrane is achieved via imposed ion dehydration and the construction of the energy well. The proper hydrophilic environment of the COF channel promotes the dissociation of Li+ from the negatively charged functional groups, allowing Li+ for hopping transport supported by the sulfonate side‐chains to shorten the diffusion path of Li+. Under high‐salinity electrodialysis conditions, the COF membrane demonstrates robust Li+/Mg2+ separation performance (No Mg2+ were detected in the collected solution), achieving efficient lithium recovery and high product purity (Li2CO3: 99.3 %). This membrane design strategy enables high energy efficiency and powerful lithium extraction in the electrodialysis lithium extraction process, and can be generalized to other energy and separation related membranes.

AbstractThe discovery of ferroelectricity in two‐dimensional (2D) semiconductors has opened a new and exciting chapter in next‐generation electronics and spintronics due to their lattice‐dimensionality‐induced unique behaviors and fascinating functionalities brought by spontaneous polarization. The emerging layered halide perovskites with 2D lattices provide a great platform for generating reduced symmetry and low‐dimensional ferroelectricity. Herein, inspired by the approach of reduced lattice dimensionality, a series of 2D layered germanium iodide perovskite ferroelectric semiconductors A2CsGe2I7 [where A=PA (propylammonium), BA (butylammonium) and AA (amylammonium)] was firstly developed, which demonstrates remarkable semiconducting features including narrow direct band gap (~1.8 eV) and high conductivity over 32.23 nS/cm. Emphatically, these layered germanium iodide perovskites manifest large in‐plane ferroelectric polarization over ~10.0 μC/cm2, mainly attributed to the large off‐centering ion displacement induced by stereo‐active lone‐pairs of Ge2+. More specifically, in contrast to three‐dimensional ferroelectric CsGeI3, the representative 2D layered BA2CsGe2I7 manifests a superior polarization‐sensitive bulk photovoltaic effect with a polarization ratio of 1.68 and high short circuit current density up to 81.25 μA/cm2, which is superior to those of reported layered halide perovskite ferroelectrics. This work provides an exciting pathway for the development of 2D ferroelectric semiconductors as well as sheds light on their further applications in photoelectronic fields.

AbstractPrecise stacking of distinct two‐dimensional (2D) rigid slabs to build heterostructures has renewed the portfolio of 2D materials, e.g., magic‐angle graphene, due to the emergence of exotic physical properties. Recently, single‐crystal heterostructures of layered perovskites have emerged as an exciting branch, while it remains scarce to achieve strong ferroelectricity in this new heterostructure family. Here, we present the first ferroelectric of 2D perovskite heterostructures as single crystal, (EA3Pb2Br7)EA4Pb3Br10 (1, EA=ethylamine), by precisely tailoring inorganic sheets via a chemical molecular scissor. It has notable ferroelectricity of large spontaneous polarization (Ps~5.0 μC/cm2) and high Curie temperature (Tc~375 K). Structurally, its inorganic framework adopts a unique 2D heterostructure that contains two different rigid slabs of {EA3Pb2Br7}n and {EA4Pb3Br10}n. This motif is self‐assembled by layer‐by‐layer clipping of rigid prototype sheets, using extra neopentylamine as a molecular chemical scissor. Unlike epitaxial growth, such a molecule‐level stacking facilitates the growth of heterostructure single crystals. Combining its strong ferroelectricity and inherent anisotropy, crystal‐based device of 1 exhibits an ultrahigh polarized‐light sensitivity up to ~37 in self‐powered mode, being the highest level of 2D perovskite ferroelectric family. Our work will facilitate the further development of ferroelectric materials for optoelectronic device applications.

AbstractEfficient CO2 capture at concentrations between 400–2000 ppm is essential for maintaining air quality in a habitable environment and advancing carbon capture technologies. This study introduces NICS‐24 (National Institute of Chemistry Structures No. 24), a Zn‐oxalate 3,5‐diamino‐1,2,4‐triazolate framework with two distinct square‐shaped channels, designed to enhance CO2 capture at indoor‐relevant concentrations. NICS‐24 exhibits a CO2 uptake of 0.7 mmol/g at 2 mbar and 25 °C, significantly outperforming the compositionally related Zn‐oxalate 1,2,4‐triazolate – CALF‐20 (0.17 mmol/g). Improved performance is attributed to amino‐functions that enhance CO2 binding and enable superior selectivity over N2 and O2, achieving 8‐fold and 30‐fold improvements, respectively, in simulated CO2/N2 and CO2/O2 atmospheric ratios. In humid environments, NICS‐24 retained structural integrity but exhibited an 85 % reduction in CO2 capacity due to competitive water adsorption. Breakthrough sorption experiments, atomistic NMR analysis, and DFT calculations revealed that water preferentially adsorbs over CO2 due to strong hydrogen‐bonding interactions within the framework. Gained understanding of the interaction between CO2 and H2O within the MOF framework could guide the modification via rational design with improved performance under real‐world conditions.

AbstractIr(III) complexes are particularly noted for their excellent photophysical properties in giving blue OLED phosphors. In this study, two distinctive carbene pro‐chelates LAH2+ and LBH2+ (or LCH2+) were employed in preparation of heteroleptic Ir(III) complexes, to which LAH2+ bears a cyano substituted benzoimidazolium along with N‐mesityl appendage, while LBH2+ (or LCH2+) carries the symmetrical benzoimidazolium entity. Notably, the reversible equilibration at high temperature was observed for m, f‐ct14 and m, f‐ct15 with a single LA chelate. In contrast, only the mer‐substituted m‐ct16 was obtained upon employing two LA chelates. All Ir(III) complexes exhibited blue photoluminescence (ΦPL
78 %) with short radiative lifetimes (τrad
1.05 μs) in solution. The Ph OLED device with m‐ct16 afforded an external quantum efficiency (EQE) of 22.8 % at 5000 cd ⋅ m−2. Moreover, the hyper‐OLED based on m‐ct16 and v‐DABNA exhibited EQE1000 of 32.1 % (EQE recorded at 1000 cd ⋅ m−2) and J90 of 15.0 mA cm−2 (current density at 90 % of max. EQE). Its suppressed efficiency roll‐off (EQE of 32.1 % and 27.7 % at 1000 cd ⋅ m−2 and 10000 cd ⋅ m−2) demonstrated a milestone in fabrication of blue OLED devices.

ABSTRACTIn order to develop novel separator for lithium batteries, a series of polyvinylidene fluoride (PVDF)/polyvinylidene fluoride‐co‐hexafluoropropylene (PVDF‐HFP)/rGO composite membranes were prepared via phase inversion method. The microstructure, thermal, and mechanical performance of composite membranes was thoroughly examined. The differential scanning calorimetry and thermogravimetric analysis results indicated that the composite membrane with 2% rGO exhibits the best thermal stability, and it could be accepted as a separator in battery. These results suggest that incorporation of nanosheets could induce more regular arrangement of chain segments, leading to better thermal stability. The ion permeation through the membrane was evaluated by electrochemical impedance spectroscopy, indicating that the whole structure in composite membrane with 2% demonstrated the most stability across various test temperatures. Additionally, increasing the concentration of electrolyte allows one to observe the information of impedance spectrum at very low frequencies that is not visible at low concentrations. This method can overcome the limitations of frequency range of electrochemical workstation. By developing PVDF‐HFP composite membranes incorporated with rGO, this study addresses the challenges regarding the thermal stability and mechanical properties of lithium battery diaphragms, offering a potential high‐performance material solution for the advancement of high‐safety and high‐performance lithium batteries.
ZnT35C Maintains Zinc Homeostasis to Regulate Spermatogenesis in Drosophila Testis
Authors: He Jiayu , Fang Yang , Zhao Long , Su Ying 
Published: January 2025

ABSTRACTZinc homeostasis contributes significantly to numerous physiological processes. Drosophila ZnT35C protein, a zinc transporter encoded by CG3994, is chiefly located on the cell membrane and facilitates the transport of zinc from the cytoplasm to the extracellular space to sustain zinc homeostasis within the organism. Previous studies about ZnT35C have involved diverse structures such as the Malpighian tubules, adult brain, and sensory nervous system. Nonetheless, the role of ZnT35C in Drosophila spermatogenesis remained unclear. In our study, we discovered that ZnT35C plays a pivotal role in Drosophila spermatogenesis. Its knockdown resulted in sperm loss and male infertility. When ZnT35C was knocked down in cyst cells, zinc was concentrated within cyst cells, inhibiting the proper development of germ cells and thereby causing the incapacity of flies to generate mature sperms. Zinc supplementation can effectively rescue this failure of spermatogenesis. Our research outcomes suggest that ZnT35C, through modulating the zinc environment within the testes, impacts the male fertility of Drosophila, occupying a crucial position in the spermatogenesis process.
