Decoding planetary surfaces by counting cracks [PDF]

open access: yesarXiv
Planets are often covered with thin cracked shells. From mud films to lithospheres of rock or ice, fracture networks form two-dimensional (2D) tessellations of convex polygons whose geometry encodes their genesis. Here we chart the geometry of 2D fracture mosaics across the solar system, and decode their formative conditions using a new dynamical crack

Versatile Selective Soldering via Molten Metal Printing for Heat‐Sensitive 3D Electronics and Smart Wearables

open access: yesAdvanced Functional Materials, EarlyView.
Selective soldering via molten metal printing enables component integration, even in heat‐sensitive applications across fields like additive manufacturing, sustainable electronics, and smart textiles. This method overcomes the temperature limitations of existing technologies.

EXPERIMENTAL STUDY OF THE HEALING OF FRACTURES [PDF]

open access: yesArchives of Surgery, 1922
This study was undertaken to clear up several obscure points in the process of healing of fractures, but chiefly to ascertain the exact role assumed by the periosteum. Three sets of experiments were performed on cats, and in all the humerus was fractured. In the first series, the humerus was fractured by direct external violence, applied laterally.

Implications for Fracture Healing of Current and New Osteoporosis Treatments: An ESCEO Consensus Paper [PDF]

open access: yes, 2018
Osteoporotic fracture healing is critical to clinical outcome in terms of functional recovery, morbidity, and quality of life. Osteoporosis treatments may affect bone repair, so insights into their impact on fracture healing are important.

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow

open access: yesAdvanced Functional Materials, EarlyView.
Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

Inducing mechanical self-healing in glassy polymer melts [PDF]

open access: yesarXiv
Glassy polymer melts such as the plastics used in pipes, structural materials, and medical devices are ubiquitous in daily life. They accumulate damage over time due to their use, which limits their functionalities and demands periodic replacement. The resulting economic and social burden could be mitigated by the design of self-healing mechanisms that

Generation of a femoral non-union model utilizing phosphate deficient mice [PDF]

open access: yes, 2013
Thesis (M.A.)--Boston UniversityFracture non-unions occur when the biological process of fracture healing fails to complete. The events that occur in the fracture healing process of mice are similar to the events that occur in humans. Inorganic phosphate

Off‐Stoichiometry Engineering of the Electrical and Optical Properties of SrNbO3 Using Oxide Molecular Beam Epitaxy

open access: yesAdvanced Functional Materials, EarlyView.
The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...

Long non-coding TRPM2-AS regulates fracture healing by targeting miR-545-3p/Bmp2

open access: yesJournal of Orthopaedic Surgery and Research
Objective Delayed fracture healing increases the suffering of patients. An in-depth investigation of the pathogenesis of delayed fracture healing may offer new direction for the prevention and treatment.
