Cool Kitchen: Processing Starch and Eggshell Powder into Sustainable Coatings for Passive Daytime Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A food‐grade cooling composite made from starch and recycled eggshell powder offers a scalable, ultra‐low‐cost solution for passive daytime radiative cooling. Easily prepared using basic kitchen tools, this material empowers communities, even in areas with limited infrastructure, to stay cooler during worsening summer heat waves.

運用問題導向學習法提升國中學生學習成效之研究 -以人文通論地理結合校本課程為例 Enhance Learning Efficiency in Junior High Schools through Problem-based Learning: The Example of Human Geography in a School-based Curriculum [PDF]

open access: yesShizi Peiyu Yu Jiaoshi Zhuanye Fazhan Qikan
近年由基層老師發起的翻轉教室教學法如雨後春筍般出現,然而全面實施時發現並不適用於所有課程及學生。問題導向學習法以學生為中心,透過老師引導並搭配微講述,利用真實問題與學生建立共鳴,可發現運用於人文通論地理的研究甚少,因此本研究利用行動研究法,探究問題導向學習法於國中七年級下學期臺灣人文通論地理的教學實踐情形,並透過準實驗研究法,實驗組實施問題導向學習法,對照組實施傳統講述教學,藉以探討問題導向學習法是否能提升學生的學業成就,最後利用問卷調查法,分析學習態度是否有所差異 ...

Wafer‐Scale Integration of α‐quartz Thin Films toward Super High Frequency Piezoelectric bioNEMS for Chikungunya Virus Detection

open access: yesAdvanced Functional Materials, EarlyView.
Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...

Myeloperoxidase Luminol Reaction – A Novel Faecal Assay for Predicting Colonoscopy Findings in Patients with Ulcerative Colitis: A Pilot Cross‐Sectional Clinical Study

open access: yesAdvanced Healthcare Materials, EarlyView.
Can luminol detect faecal inflammation? This study explores the development and optimisation of a rapid novel assay ‐ Myeloperoxidase Luminol Reaction (MPOLR) for the detection of faecal myeloperoxidase activity. This simple and rapid luminol‐based approach competes with clinically validated faecal biomarkers in predicting endoscopic findings in ...

Divergence – Is it Geography? [PDF]

open access: yes
This paper tests directly a geography and growth model using regional data for Europe, the US, and Japan during di®erent time periods. We set up a standard geography and growth model with a poverty trap and derive a log- linearized growth equation that ...
