Pneumosinus dilatans with shift of midline intracranial structures: A case report

Radiology Case Reports
Pneumosinus dilatans (PSD) is an abnormal dilatation and enlargement of one or more paranasal sinuses, extending beyond the anatomic bony boundaries, without defect or thinning of its bony walls. It is documented by only a few reports. Usually asymptomatic, it is in general found incidentally on imaging.

Multimaterial 3D Printing in Activating Bath Enables In Situ Polymerization of Thermosets with Intricate Geometries and Diverse Elastic Behaviors

Advanced Materials, EarlyView.
A new embedded 3D printing (EMB3D) strategy enables in situ polymerization of DCPD/COD‐based inks within a fugitive reactive matrix where the activator in the matrix cures the printed filament. Cured ink properties are tunable through DCPD‐COD comonomer ratios, yielding materials from stiff thermosets to soft elastomers.

Anatomic brain asymmetry in vervet monkeys. [PDF]

, 2011
Asymmetry is a prominent feature of human brains with important functional consequences. Many asymmetric traits show population bias, but little is known about the genetic and environmental sources contributing to inter-individual variance.

One‐Step Coordinated Multi‐Kinetic 4D Printing of Human Vascularized Cardiac Tissues with Selective Fast‐Shrinking Capillaries

Advanced Materials, EarlyView.
This study presents a novel 4D bioprinting technique for fabricating cardiac tissues with complex microvasculature. Unlike traditional 3D printing, it enables capillary‐scale structure formation via selective post‐printing shrinkage. This approach overcomes resolution limits of printing cell‐laden hydrogels, allowing the creation of functional ...

Casimir Force on Real Materials - the Slab and Cavity Geometry [PDF]

, 2006
We analyse the potential of the geometry of a slab in a planar cavity for the purpose of Casimir force experiments. The force and its dependence on temperature, material properties and finite slab thickness are investigated both analytically and ...

Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

Advanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.

Investigation of Exothermic Behaviors of Energetic Particles in Microfluidics Channels

Advanced Materials Technologies, EarlyView.
Scheme and representative frames of delivery, ignition, and combustion process of core@shell Al@CuO energetic material in a microchannel. The electrical discharge occurred at the throat of microchannel leads to the combustion of the energetic reaction, causing the formation of high‐momentum butterfly‐shaped jet at the throat.
