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

open access: yesAdvanced 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.

The angle of repose: Facilitation and its effects on the Brachypodium distachyon grass complex

open access: yes
Plant communities are a complex web of interactions which may harbor inherent resilience to environmental stressors. One means of coping with changing conditions may be interspecific facilitation, a process in which neighboring perennial plants positively influence spatially associated annual species, especially in harsh conditions.

Standardized Effect Measures Informing Next‐Generation Strategies for Mechanical Stimulation in Cartilage Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This systematic review quantitatively compares conventional mechanical stimulation strategies in cartilage tissue engineering across 85 heterogeneous in vitro studies. Applying standardized effect measures, meta‐analysis reveals that combined compression and shear loading optimally promotes cartilage matrix development.

Construction of Discrete Element Model for Individual Sugarcane Roots and Calibration of Contact Parameters

open access: yesAgriculture
Sugarcane is an important economic crop in southern China. Affected by typhoons, it is prone to lodging, which not only increases the difficulty and loss rate of mechanical harvesting but also reduces the sugar content.

Layered granule chute flow near the angle of repose [PDF]

open access: yes, 1985
A natural, two-layered gravity flow of sand can be obtained on chutes inclined at angles slightly above the angle of repose of the sand. The top-surface layer is free-flowing, is thin, and moves rapidly at supercritical velocity.

Natural Biomaterials for Osteochondral Repair: From Source to Strategy

open access: yesAdvanced Healthcare Materials, EarlyView.
Biological origin‐guided overview of natural biomaterials and therapeutic strategies for osteochondral tissue engineering. The circular diagram categorizes representative materials and strategies into plant/algae‐derived, microbial‐derived, animal‐derived, and human‐derived sources, centered on an osteochondral defect repair model.

Wallace Stegner's "Angle of Repose": One reader's response.

open access: yes, 1989
This dissertation reads Wallace Stegner's Angle of Repose by combining objective and subjective critical approaches in an attempt to bridge the gap between storytelling understood formalistically and story in its moving immediacy.

Influence of Particle Morphology on Angle of Repose Derived from Hopper Flow Tests Using 3D DEM Simulations

open access: yes
The angle of repose holds significant importance within granular systems, serving as a key indicator of material packing and flow behavior. In this work, we investigated the impact of particle morphology on the repose angle (AOR) using a series of ...

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
