Pentagonal Pdte2 Monolayer For Sustainable Solar-Driven Hydrogen Production, Narender Kumar, Shambhu Bhandari, Dario Alfè, Ravindra Pandey, Nacir Tit

Michigan Tech Publications

This investigation demonstrates that the pentagonal PdTe2 (penta-PdTe2) monolayer is a highly tunable two-dimensional (2D) photocatalyst, characterized by the bandgap of 1.87 eV and high hole mobility. Using density functional theory calculations with the HSE06 functional, we show that tensile strain engineering (particularly at +2% and +3%) is essential for enabling spontaneous water splitting. At these strain values, the valence-band maximum and conduction-band maximum straddle the water redox potentials (H+/H2 and O2/H2O) under both acidic (pH = 0) and neutral (pH = 7) conditions. The monolayer's low hole effective mass facilitates rapid charge extraction, mitigating recombination and driving the oxygen …

Text-Fabric And The Bibleol: A Fruitful Combination For Greek Exercise Development, Cedric Vine, Oliver Glanz

Andrews University Seminary Studies (AUSS)

Two of the major challenges for an instructor of any language course are (1) the limited amount of exercise material available for students and (2) compromised exams requiring the laborious creation of new exams. These challenges increase significantly when teaching biblical languages (Hebrew, Aramaic, Greek). However, BibleOnlineLearner (BibleOL) has now addressed both of these challenges. When an instructor uses BibleOL, he/she can easily create an exercise that targets a specific learning object (e.g., learning the Greek present tense of the regular conjugation). BibleOL then creates randomized exercises for each student. Unless the instructor decides otherwise, the BibleOL exercise will be …

When The Chatbot Is Wrong On Purpose: Using Genai Role-Play To Build Student Engagement And Critical Ai Fluency, Sierra Adare-Tasiwoopa Api

AI in the Classroom: A Virtual Summit

In this hands-on workshop, participants will explore how customized AI chatbots can be used to increase student engagement while also teaching students to question AI-generated information. The workshop centers on a role-playing game scenario in which students interact with a chatbot non-player character (NPC) that serves as a guide, informant, but one that sometimes provides incomplete, misleading, or invalid information. Rather than treating chatbot errors as failures, the activity uses them as opportunities for students to practice verification, source evaluation, metacognition, and discipline-specific reasoning.

Participants will first experience a short version of the role-playing activity as students. They will then …
