MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance
Advanced Functional Materials, EarlyView.Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Geometric Interpretation of Surface Tension Equilibrium in Superhydrophobic Systems
Entropy, 2015 Surface tension and surface energy are closely related, although not identical concepts. Surface tension is a generalized force; unlike a conventional mechanical force, it is not applied to any particular body or point.

Covalent Organic Frameworks for Water Sorption: The Importance of Framework Physical Stability
Advanced Functional Materials, EarlyView.This study explores the water‐vapor stability of 2D covalent organic frameworks (COFs) with varying pore sizes. Results reveal microporous COFs demonstrate superior stability compared to mesoporous ones, despite lower water uptake. Mesoporous keto‐enamine‐linked COFs show enhanced stability due to intralayer hydrogen bonds, confirmed by simulations and

Complementary Logic Driven by Dielectrophoretic Assembly of 2D Semiconductors
Advanced Functional Materials, EarlyView.Scalable, parallel fabrication of complementary logic gates is demonstrated using electric‐field‐driven deterministic assembly of electrochemically exfoliated 2D n‐type MoS2 and p‐type WSe2 nanosheets. This strategy yields MoS2 and WSe2 transistors featuring average mobilities of 4.3 and 3.0 cm2 V−1 s−1, respectively, and on/off ratios of > 104 ...

Determination of contact angle hysteresis of water microdroplets evaporating on hydrolyzed PET foils [PDF]
Acta Montanistica Slovaca, 2013 Moderately hydrophobic surfaces of PET foils were gradually hydrophilized by their immersion in NaOH solutions of increasing concentration. Then, the contact angle and geometric factors of microliter water drops, deposited on these polymer surfaces, were
