Super‐Tough Silk: The Potential of Knots in Evolved Spiders

open access: yesAdvanced Functional Materials, Volume 35, Issue 15, April 10, 2025.
The toughness of spider silk can be further significantly enhanced if spiders evolved the –currently absent/undiscovered– ability to tie knots in their silk. The results on 393 spiders suggest toughness increments by one or two orders of magnitude and thus a new perspective on how knotting can serve as a key innovation in spider evolution and in ...

Critical Heegaard Surfaces and Index 2 Minimal Surfaces [PDF]

open access: yesarXiv, 2002
This paper contains the motivation for the study of critical surfaces. In previous work the only justification given for the definition of this new class of surfaces is the strength of the results. However, when viewed as the topological analogue to index 2 minimal surfaces, critical surfaces become quite natural.

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.

Stratum Corneum‐Inspired Zwitterionic Hydrogels with Intrinsic Water Retention and Anti‐Freezing Properties for Intelligent Flexible Sensors

open access: yesAdvanced Functional Materials, EarlyView.
A novel stratum corneum‐inspired zwitterionic hydrogel is developed for intelligent, flexible sensors, featuring intrinsic water retention and anti‐freezing properties. The quasi‐gel, composed of hygroscopic polymers and bound water, maintains its softness across a wide range of humidity.

Discovery of an Intrinsic Antiferromagnetic Semiconductor EuSc2Te4 With Magnetism‐Driven Nonlinear Transport

open access: yesAdvanced Functional Materials, EarlyView.
EuSc₂Te₄, an antiferromagnetic semiconductor, exhibits a nonlinear Hall effect (NLHE) characterized by quadratic current–voltage behavior. Combined experimental and theoretical studies reveal that this NLHE is linked to its antiferromagnetism and involves contributions from the quantum metric.

Cell Membrane Vesicle Camouflaged Artificial Cells

open access: yesAdvanced Functional Materials, EarlyView.
Artificial cells camouflaged with a cell membrane vesicle coating are able to assemble into synthetic aggregates that exhibit rudimentary communication capabilities. Additionally, when these artificial cells are equipped with antioxidant capabilities, they are able to protect the intracellular homeostasis in HepG2 cells present in semi‐synthetic ...

FRACTAL STRUCTURE OF TITANIUM NITRITE DEPOSITED ON STAINLESS STEEL SUBSTRATE [PDF]

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2014
On the basis of images obtained using scanning tunneling microscope, it was shown that the fractal dimension can be considered as some universal surface characteristic of the titanium nitrite, deposited on stainless steel.
