Poly(1,4‐anthraquinone) as an Organic Electrode Material: Interplay of the Electronic and Structural Properties due to the Unusual Lone‐Pair‐π Conjugation

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
In this study, the unique role of the unusual lone‐pair‐π conjugation mechanism in poly(1,4‐anthraquinone) (P14AQ) is explored as an organic electrode material. Unlike traditional π‐π interactions, P14AQ's conjugation involves lone pairs of oxygen atoms interacting with the π cloud of adjacent units, enabling stable charge transport even with minimal π‐

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

open access: yesAdvanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Static balancing behaviour of the mandible

European Journal of Oral Sciences, 2015
The objective of this study was to investigate the mechanisms of physiological control of the craniomandibular system during force‐controlled biting: in intercuspation, restricted by predetermined anatomic–geometrical conditions [i.e. biting in intercuspation (BIC)]; and on a hydrostatic system [i.e.

Statically balanced brakes

Precision Engineering, 2016
Abstract Conventional brakes require a powerful actuator, leading to large, heavy and in most cases energy consuming brakes. This paper introduces a fundamentally different brake concept called statically balanced brakes (SBBs). SBBs do not require any actuation force to maintain a braking torque and only have to move a small mass to vary that torque.

The Role of Peripheral Vision in Static Balancing

Ergonomics, 1967
Abstract A study was made to determine the role of peripheral vision in static balancing. Three groups of subjects were tested under sighted and blindfold conditions, and also under a minimal cues condition. One of these groups was trained in the use of peripheral vision and after five days achieved sighted competence under the minimal cues condition ...
