Ekphrasis em música: os Quadrados Mágicos de Paul Klee na Sonata para violão solo de Leo Brouwer Ekphrasis in music: the Magic Squares by Paul Klee in the Sonata for solo guitar by Leo Brouwer

open access: yesPer Musi, 2009
Para Siglind Bruhn, o conceito de ekphrasis, usado nas artes plásticas e na literatura, pode ser aplicado também para certas obras musicais. Partindo dessa concepção, desenvolvida pela autora na obra Musical Ekphrasis: composeres responding to poetry and

Bioadhesive‐Integrated 3D‐Printed Multilayer Scaffolds Secure a Mechanically‐Stable Osteoimmune Niche for Enhanced Bone Augmentation

open access: yesAdvanced Science, EarlyView.
A 3D‑printed multilayer adhesive scaffold, firmly anchored to bone defects by simple finger pressing, suppresses micromotion and secures mechanical stability of the osteogenic niche. This stabilization likely contributes to the enhanced bone augmentation by fostering a pro‑regenerative mechano‐immune profile—characterized by M2‑like macrophage ...

New Concepts in Magic Squares: Cornered Magic Rectangles in Construction of Magic Squares of Orders 24 and 26

open access: yes, 2023
This work brings magic squares of orders 24 and 26. These are constructed based on cornered magic rectangles and/or cornered magic squares. Order 24 is with four equal sums cornered magic squares of order 12x12.

A New Algorithm Based on Magic Square and a Novel Chaotic System for Image Encryption

open access: yesJournal of Intelligent Systems, 2019
This article introduces a simple and effective new algorithm for image encryption using a chaotic system which is based on the magic squares. This novel 3D chaotic system is invoked to generate a random key to encrypt any color image. A number of chaotic

A Multiscale Mechanistic Framework for Polydopamine Dyeing in Ultrablack Wool Textiles

open access: yesAdvanced Science, EarlyView.
Ultrablack photonic textiles are enabled through polydopamine (PDA) dyeing, which is governed by the interplay of PDA chemistry, wool surface topology and chemistry, and hierarchical fiber–yarn–fabric architecture. Fabric architecture emerges as a primary and previously underappreciated design lever for wide‐angle optical performance.

Magnetic Water Cleaning of Estrogens via Tight yet Dynamic Binding to Nanoparticles

open access: yesAdvanced Science, EarlyView.
Micropollution is one of the big challenges humanity faces with estrogen hormones being emerging pollutants of concern. Here, a supramolecular design strategy is presented that generates a simple nano‐adsorbent material to magnetically remove low‐concentrated estrogens from water.

Short Sb···Sb Contacts in Polymorphic Tris(p‐Tolyl)Antimony: A Hallmark of Organoantimony(III) Solid‐State Chemistry?

open access: yesAngewandte Chemie, EarlyView.
Discovery of polymorphism in solid tris(p‐tolyl)antimony(III) highlighted short, direct antimony‐antimony contacts, with interatomic separation shorter than the sum of the van der Waals radii, and calculated interaction energy of ca. 26 kJ mol−1 that includes a significant dispersion component.
