Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

open access: yesAdvanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Spectroscopic and theoretical investigations of complexes of aluminum ion and boric acid with aromatic organic acids

open access: yes, 2014
天然有機質是環境中常見的物質,由於其含有許多官能基如羧酸基與酚基等,進而在環境中許多常見的反應裡,扮演重要的角色。而金屬與天然有機質的鉗合反應是取決於有機質上之官能基及鉗合金屬的特性。因此預測以及研究鋁與硼酸對同時存在兩種已知官能基之錯合行為則顯得相當重要。本次報告的目標在研究不同官能基的反應性以及確認三價鋁與硼酸對不同有機物之錯合位置間的選擇性。我們以電子光譜實驗三價鋁與硼酸在甲醇下與有機質的錯合結果,並得到之光譜結果有明顯逐漸位移之現象。為了獲得鉗合機制以及解釋其反應途徑 ...

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

open access: yesAdvanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.
