Vertebrate fauna of the Roman period, migrations period and Medieval period in Vojvodina (Serbia) [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2014
Based on current published and unpublished research results, a total of 16 vertebrate species members of mammal (Mammalia), bird (Aves) and osteichthyes (Osteichthyes) classes have been registered at 11 archaeological sites from the Roman Period

Modular Assembly of Dynamic Polymer Networks From Heteroaffinity Cross‐Links to Multivalent Proteins

open access: yesAngewandte Chemie, EarlyView.
This study develops a method to modularly assemble oligomeric binding proteins, like streptavidin, using heterobifunctional cross‐linkers that have both a strong‐ and a weak‐affinity binding moiety. These dynamic cross‐linkers enable the assembly of polymer networks with unique meta‐stable nonequilibrium topologies, and that exhibit chemically tunable ...

Inactivating SARS‐CoV‐2 Virus with MOF‐Composites as Smart Face Masks

open access: yesAdvanced Functional Materials, EarlyView.
In situ preparation and functionalization of MOF@Cotton fabrics as smart face masks for the immobilization of proteins and inactivation viruses, such as SARS‐CoV‐2. Abstract The significant impact of the SARS‐CoV‐2 (COVID‐19) pandemic outbreak on people's lives has highlighted the urgent need for effective personal protective equipment.

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.

Uwagi o triangulacji jako metodzie analiz przestrzennych, czyli czego nadal nie wiemy o strukturach osadniczych okresu przedrzymskiego i okresu wpływów rzymskich na Nizinie Pyrzyckiej

open access: yesPrzegląd Archeologiczny
The text concerns triangulation as a method of settlement analysis as proposed by Valde-Nowak (1995; 2001), as well as subsequent method modifications introduced by Krajewski (2003; 2004).

Scalable Thermal Engineering via Femtosecond Laser‐Direct‐Written Phononic Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that femtosecond laser‐induced periodic surface structures (fs‐LIPSS) can function as phononic metasurfaces, reducing thermal conductivity below the plain thin‐film limit. Phonon Monte Carlo analysis reveals that the periodic structures restrict phonon mean free paths.

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

open access: yesAdvanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

A New Mechanism Enabling Micron Scale Electron–Hole Synchronized Recombination in Bulk Halide Perovskites

open access: yesAdvanced Optical Materials, EarlyView.
This work reports the first observation of long‐range synchronized photoluminescence blinking in vapor‐grown, fully inorganic CsPbBr3 microcrystals, extending over 10 µm. The observations contradict supertrap‐based models and link blinking to Pb‐rich growth conditions. A new mechanism is established, in which hole diffusion mediates collective electron–

Compliant Polymeric Sheet‐Based Heat Exchangers

open access: yesAdvanced Science, EarlyView.
This work presents flexible, transparent, and deployable polymer heat exchangers that achieve a heat transfer capacity per cost up to 4x higher than the state of the art, surpassing both metal and other polymer counterparts. The tube‐on‐tube design enables efficient heat transfer without flow occlusion, while the lightweight, corrosion‐resistant, and ...
