4D Printing of Self‐Immolative Polymers

open access: yesAdvanced Functional Materials, Volume 36, Issue 23, 19 March 2026.
The integration of self‐immolative polymers (SIPs) into light‐based 3D printed structures is presented as a new “living” 4D printing strategy. By exploiting their metastability and stimuli‐responsiveness, SIP‐containing printed objects can undergo rapid and triggered degrowth under ambient conditions and subsequent regrowth through polymer ...

Sustainable Synthesis of Edge‐Dominant Pyridinic Nitrogen‐Doped Carbon from Tannic Acid for High‐Performance Vanadium Redox Flow Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
Graphitic carbon doped with an edge‐predominant pyridinic structure is synthesized using a sustainable, rapid microwave process. The material enhances vanadium redox reactions, improving energy efficiency and durability in VRFB electrodes, with a 94.12% discharge capacity retention over 1000 cycles.

Enumeration of Kekulé Structures in Defective Patterns of Rectangular Graphite [PDF]

open access: yes, 2006
The number of Kekulé structures is an indicator of the aromatic character of the underlying polybenzenoid. Graphite is a polybenzenoid. In this paper, a new algorithm is proposed for determining the number of Kekulé structures in rectangular graphite and

Ladder‐Type Benzene‐Perylene Dyes with Efficient Laser Properties in the Near‐IR by Detracting/Activating Low/High Frequency Vibronic Modes

open access: yesAdvanced Functional Materials, Volume 36, Issue 17, 26 February 2026.
The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential

Against the Tide. A Critical Review by Scientists of How Physics and Astronomy Get Done [PDF]

open access: yes, 2008
Nobody should have a monopoly of the truth in this universe. The censorship and suppression of challenging ideas against the tide of mainstream research, the blacklisting of scientists, for instance, is neither the best way to do and filter science, nor ...

CSF Surfactant Protein Changes in Preterm Infants After Intraventricular Hemorrhage [PDF]

open access: yes, 2023
Introduction: Surfactant proteins (SP) have been shown to be inherent proteins of the human CNS and are altered during acute and chronic disturbances of CSF circulation.

Modular Amphiphilic Design Enables Control of Oblique vs J‐Type Exciton Coupling in Aqueous Self‐Assembly

open access: yesChemistryEurope, Volume 4, Issue 2, February 2026.
Herein, a family of amphiphilic aza‐BODIPY dyes is rationally designed to precisely control the type of exciton coupling (oblique vs J‐type) and the nanoscale morphology in aqueous media. By systematically varying the hydrophilic and hydrophobic substituents, new structure–property relationships that extend the understanding beyond traditional ...

Aromaticity of Carbon Nanotubes [PDF]

open access: yes, 2006
Carbon nanotubes (CNTs) are aromatic, peri-condensed benzenoids, composed of sp2 carbon atoms; the carbons are arranged in a graphite-like, hexagonal pattern.

Enumeration of saturated and unsaturated substituted N-heterocycles

open access: yes, 2023
Mathematical and computational approaches in chemistry and biochemistry fill a gap in respect to the analysis of the physicochemical features of compounds and their functionality and provide an overview of known as well as yet unknown, but hypothetically
