Kiven lumo

Aikuiskasvatus, 2006
Kansalais- ja työväenopistot – määrältään noin 250 opistoa – täyttyivät jälleen tänä syksynä innokkaista aikuisopiskelijoista. Vuosittain kansalais- ja työväenopistoissa opiskelee liki 800 000 suomalaista. Kysytyimpiä ovat vieraat kielet, kättentaidot ja liikunta. Tässä kuvattu geologinen kivikurssi on vapaan sivistystyön piirissä erikoiskurssi.

Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Energy Level Modulation of HOMO, LUMO, and Band‐Gap in Conjugated Polymers for Organic Photovoltaic Applications [PDF]

, 2013
To devise a reliable strategy for achieving specific HOMO and LUMO energy level modulation via alternating donor‐acceptor monomer units, we investigate a series of conjugated polymers (CPs) in which the electron withdrawing power of the acceptor group is

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection

Advanced Materials, EarlyView.
An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...
