Advanced Functional Materials, EarlyView.Nanosecond pulse laser texturing yields superhydrophobic and superhydrophilic AA2024 surfaces. Salt‐spray tests show that periodic superhydrophobic patterns suppress pitting, whereas superhydrophilic textures enhance it, linking laser‐induced morphology, wettability, and oxide chemistry to corrosion resistance.

Fresh-water dinoflagellates of Maryland [PDF]
, 1947 Collections were made in the summer of 1942 and again at different times in 1946 and 1947. Some collections were not sufficient in numbers to allow for proper identification, so the present paper does not give a complete list.

Shaping of Biohybrid Functional Living Materials
Advanced Functional Materials, EarlyView.This work demonstrates a strategy for shaping living mycelium into functional materials by directing its natural growth. Nanoparticles armor hyphae, micron‐scale particles entangle within the network, and printed hydrogel architectures steer expansion, creating defined geometries.

Journal of the Belgian Society of Radiology, 2015 Background: A 53-year-old male was referred to the department of maxillofacial surgery for the extraction of a destructed wisdom tooth. A preoperative orthopantomogram revealed a well delineated ovoid, radiolucent lesion at the left angle of the mandible.

Advanced Functional Materials, EarlyView.Reprogrammable multi‐material smart textiles knitted from liquid crystal elastomer fibers undergo 2D and 3D deformation under thermal and photo stimuli. Circularly knitted tubular structures reversibly contract in radial and axial directions, enabling autonomous climbing, liquid release, and micro pumping.

SYMMETRIES IN IMAGES ON ANCIENT SEALS [PDF]
, 2008 In this paper, we discuss the presence of symmetries in images engraved on ancient seals, in particular on stamp seals. Mainly used to secure the containers from tampering and for owner's identification, these objects appeared during the 5th millennium ...

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel
Advanced Functional Materials, EarlyView.This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Ovals in Translation Hyperovals and Ovoids
European Journal of Combinatorics, 1997 An ovoid in \(\text{PG}(3,q)\) is a set of \(q^2+ 1\) points, no three of which are collinear. A hyperoval in \(\text{PG}(2, q)\) is a set of \(q+2\) points, no three of which are collinear. (A hyperoval cannot exist unless \(q\) is even.) A hyperoval is a translation oval if it is fixed by a group of order \(q\) consisting of elations, all with the ...

Advanced Functional Materials, EarlyView.Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.
