Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

Students’ Computational Thinking in GeoGebra-Based Geometric Transformation Learning: Analytical Dimensions of the Visual-Algorithmic Process

Edumatica: Jurnal Pendidikan Matematika
Geometric transformation requires students to integrate visual, symbolic, and procedural reasoning to understand changes in geometric objects. However, students recognized transformation patterns visually but struggled to translate them into systematic ...

Abstraction level of van Hiele’s theory: Occurrence of side effects in GeoGebra integration

Jurnal Elemen
One of the obstacles to teaching geometric transformation is the complex procedures that require a broad base of prerequisite knowledge. This complexity often leads students to focus on rote memorization and procedural calculations instead of ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Desarrollo de conocimiento geométrico euclidiano y uso de mapas

Avances en Psicología Latinoamericana, 2013
We run an experiment in order to examine 60 Colombian children’s performance on a task that evaluates the use of ‘pure’ geometric maps for locating objects in a 3D space; the task was adapted from Spelke, Gilmore & McCarthy (2011).

Instructional-based learning of cyclic quadrilateral theorems: Making geometric thinking visible and enhancing learners’ spatial and geometry cognitions

Pythagoras
Geometry learning has a long history with the connection to human cognitive development. The ability to mentally or physically orient 2D shapes or 3D objects in space is believed to support achievement in science, technology, engineering, and mathematics
