Bone is a complexly structured tissue and hierarchically organized from macro to nano levels of dimensions. Biomaterial devices developed to replace and interact with bone tissues have been designed from the macro to nano perspective to provide suitable performance in acquiring primary and biological stability. Macro level designed features provide mechanical interlock and primary stability to implants inside the bone. Surface micro and nano structures influence cells behavior to promote the secondary or biological stability, reaching successful osseointegration.

Pseudomorphic Transformation in Nanostructured Thiophene-Based Materials.
ACS Nano

This study reveals the capability of nanostructured organic materials to undergo pseudomorphic transformations, a ubiquitous phenomenon occurring in the mineral kingdom that involves the replacement of a mineral phase with a new one while retaining the original shape and volume. Specifically, it is demonstrated that the postoxidation process induced by HOF·CHCN on preformed thiophene-based 1D nanostructures preserves their macro/microscopic morphology while remarkably altering their electro-optical properties by forming a new oxygenated phase. Experimental evidence proves that this transformation proceeds via an interface-coupled dissolution-precipitation mechanism, leading to the growth of a porous oxidized shell that varies in thickness with exposure time, enveloping the pristine smooth core.

For cultured meat to effectively replace traditional meat, it is essential to develop scaffolds that replicate key attributes of real meat, such as taste, nutrition, flavor, and texture. However, one of the significant challenges in replicating meat characteristics with scaffolds lies in the considerable gap between the stiffness preferred by cells and the textural properties desired by humans. To address this issue, we focused on the microscale environment conducive to cell growth and the macro-scale properties favored by humans.

Based on the basic theoretical framework of the Bi-directional Evolutionary Structural Optimization method (BESO) and the Solid Isotropic Material with Penalization method (SIMP), this paper presents a multiscale topology optimization method for concurrently optimizing the sandwich structure at the macro level and the core layer at the micro level. The types of optimizations are divided into macro and micro concurrent topology optimization (MM), macro and micro gradient concurrent topology optimization (MMG), and macro and micro layered gradient concurrent topology optimization (MMLG). In order to compare the multiscale optimization method with the traditional macroscopic optimization method, the sandwich simply supported beam is illustrated as a numerical example to demonstrate the functionalities and superiorities of the proposed method.

Article Synopsis
- Immobilized carbonic anhydrase (CA) enhances CO absorption in potassium carbonate (PC) solutions, presenting a viable alternative to traditional amine-based carbon capture methods.
- The study developed cross-scale models to assess how different enzyme immobilization materials—ranging from nanoparticle to macro-scale carriers—affect CO absorption rates, finding that nanoscale carriers are most effective.
- While increasing enzyme activity can boost absorption rates, diffusion limits, particularly in the liquid phase, impose an upper limit to this enhancement, and smaller particle sizes below 0.35 μm significantly improve performance over benchmark solutions.
