ALGORITHMS FOR THE RESEARCH OF STRENGTH AND STABILITY OF REINFORCED ORTHOTROPIC SHELLS

Structural Mechanics of Engineering Constructions and Buildings, 2014
The paper describes several algorithms based on the method of parameter continuation for thin-walled orthotropic shells. The basis of the study incorporated a mathematical model that takes into account the geometric nonlinearity, lateral shifts, as well ...

The Distribution of Stress in a Sandwich Conical Shell Panel Under Combined Load

Procedia Engineering, 2014
AbstractThe paper presents an analysis of the stress distribution in the open, cone-shaped, sandwich shell panel. The shell under consideration consists of two load-carrying facings and a core layer of the soft type. The facings are made of an isotropic, compressible, work-hardening material and they are geometrically and physically symmetrical, so ...

A Novel Decellularized Fibrocartilage Graft Promotes Tympanic Membrane Repair

Advanced Healthcare Materials, EarlyView.
An off‐the‐shelf decellularized porcine meniscus fibrocartilage graft (MEND) is engineered for pediatric tympanoplasty. Featuring a microchannel architecture that promotes host cell invasion, MEND rapidly closes tympanic membrane perforations and fully remodels in vivo, outperforming fascia and matching cartilage grafts while avoiding donor‐site ...

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

Advanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Genipin‐Crosslinked, Silane‐Anchored 3D Tumor–Stroma Microtissues for High‐Content On‐Chip Drug Testing

Advanced Healthcare Materials, EarlyView.
We describe a microfluidic tumor‐stroma co‐culture model, engineered to resist collagen‐hydrogel contraction driven by fibroblast activity. Surface silanization with APTES covalently anchors the matrix to the chip, while Genipin crosslinking progressively increases stiffness and elasticity without harming cells. This supports >10 days of co‐culture and

A Game-Changer in Architecture

Challenging Glass Conference Proceedings
A new large-format glass bending furnace has been developed to advance the current boundaries of hot glass forming for architectural applications. The new system can process glass panels up to 11.5 × 3.6 m with a maximum bending pitch of 1.2 m and radii

Flash Assembloids: A Rapid Biofabrication of a Platform for Modeling Early Glioblastoma Invasion at the Glioblastoma–Brain Organoid Interfaces

Advanced Healthcare Materials, EarlyView.
This study presents a bioengineered assembloid (ASM) system combining glioblastoma (GBM) cells in oxidized alginate (OA) microgels with dorsal organoids (DOs). This model simulates brain tumor‐host interactions, revealing enhanced GBM invasion, altered gene expression, and aggressive infiltration patterns, demonstrating ASM as a valuable platform for ...

Physical durability and insecticidal activity of long-lasting insecticidal nets in Cruzeiro do Sul, Brazil

Scientific Reports
Vector control is one of the principal strategies used for reducing malaria transmission. Long-lasting insecticidal bed nets (LLINs) are a key tool used to protect populations at risk of malaria, since they provide both physical and chemical barriers to ...

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

Advanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.
