Copper Removal with Zeolite/Polylactic Acid Beads: Neural Networks and Fixed-Bed Column Insights
In this study, we evaluate the adsorption efficiency of Philippine natural zeolite/polylactic acid (PNZ/PLA) composite beads for copper removal in fixed-bed columns. The beads were synthesized via alginate cross-linking and characterized for structural, thermal, and adsorption properties. Fourier-transform infrared (FTIR) spectroscopy confirmed polymer–zeolite interactions and Cu2+ coordination, whereas thermogravimetric analysis (TGA) and X-ray diffraction (XRD)...
Epoxidised Philippine natural rubber for tough and versatile 3D printable resins: a mixture design and neural network approach
Natural rubber (NR), valued for its high toughness and elongation, was incorporated into digital light processing (DLP) 3D printing resins to enhance mechanical performance using epoxidised Philippine NR (EPNR), optimised by statistical and machine learning methods. EPNR blends (0–10%) with cationic photo-initiator (CPI) and photo-curable commercial resin (PCR) were formulated using a solvent blending technique....
Understanding the Ecopoetics Pedagogy of Preservice English as a Second Language Teachers: A Case Study Using Robert Frost’s Fire and Ice
The prevalence of ecological and environmental hazards that adversely impact human lives necessitates the intensification of ecological literacy for the populace. This deepening of people’s knowledge of environmental science for disaster risk reduction and mitigation can be realized through literary pedagogy centering on ecocriticism. Hence, this qualitative study utilizing a case study approach aims to...
An on-chip temperature sensor with 0.5 °C resolution and 0.34% linearity error using 180-nm CMOS process
This investigation demonstrates an on-chip temperature sensor with a maximum linear error less than 0.4% and 0.5 °C resolution. The design comprises Current-to-Frequency Converters (CFC), complementary (CTAT), and proportional (PTAT) to absolute temperature current generator circuits. Most important of all, the proposed sensor is featured with the ratio of these two currents to enhance the...
