Enhancing Optoelectronic Properties in Phthalocyanine‐Based SURMOFs: Synthesis of ABAB Linkers by Avoiding Statistical Condensation with Tailored Building Blocks

open access: yesAdvanced Functional Materials, EarlyView.
A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

open access: yesAdvanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Gingival Pigmentation and Its Association with Skin Complexion and Periodontal Status Among Patients Attending a Tertiary Hospital in Nigeria: A Cross-Sectional Study

open access: yesNigerian Dental Journal
Introduction: Gingival color varies among different races and can be affected by a number of factors including pigmentation. Gingival pigmentation is of aesthetic concern in some individuals and has been linked to skin complexion.

Acral melanosis

open access: yesPigment International, 2018
The term “acral” means the distal portions of the limbs (hand, foot) and the head (ears, nose). The term acral melanosis is loosely applied to an increase in melanin pigmentation, in a diffuse, reticulate, or focal pattern over the distal parts of the ...

Electrochemical reduction of oxygen catalyzed by Pseudomonas aeruginosa [PDF]

open access: yes, 2010
Pseudomonas aeruginosa has already been shown to catalyze oxidation processes in the anode compartment of a microbial fuel cell. The present study focuses on the reverse capacity of the bacterium, i.e. reduction catalysis. Here we show that P. aeruginosa
