3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Dynamic flow, broken surface anchoring, and switching bistability in three-terminal twisted nematic liquid-crystal displays

, 2001
We investigate the switching bistability between the Φ and Φ + π twist states in liquid-crystal cells with a three-terminal electrode structure. Based on general nematohydrodynamic equations and a modeling potential of surface anchoring, numerical ...

Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...

Theoretical and experimental analysis of surface anchoring in the surface stabilization of ferroelectric liquid crystal cells [PDF]

Based on the response of a chiral smectic liquid crystal to electrical excitation, this paper develops a theoretical calculation to explain the observed phenomenon in a confined structure, with the aim to establish a connection between these phenomena ...

Resolving the Cu(bdc) Conundrum: Identifying Non‐Porous Packing of Prototypical Coordination‐Network Thin Films Combining Advanced Diffraction Techniques and Computational Modelling

Advanced Functional Materials, EarlyView.
Solution‐processed Cu(bdc) forms prototypical MOF thin films for which a multitude of not fully satisfactory structural models have been suggested. Combining rotating grazing‐incidence diffraction and X‐ray reflectivity on two complementary samples with density‐functional theory, we first discard the previously suggested models and then identify a non ...

The Anchoring of a Cholesteric Liquid Crystal at the Free Surface

, 1996
The free surface of a cholesteric oligomer, examined by Atomic Force Microscopy, shows a periodic relief that is in relation to the half helical pitch. A thorough discussion of this relief and of the structure of the interfacial region which result from ...

Long‐Range Coordination Environment Modulates Single‐Atom Local States and Systemic Impact on CO2 Photoconversion

Advanced Functional Materials, EarlyView.
Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.
