Strong Interactions in Crystalline Vacuum [PDF]

arXiv
A multiscale expansion procedure reveals a crystalline vacuum state arising as a result of resonant interactions among weak Planck-scale waves on spinor and cospinor manifolds. Quarks are presented as elastic modulations of the vacuum crystal. The complementing modes are identified with colors, and distinctions between flavors are attributed to ...

Unlocking Multimodal Nonlinear Microscopy for Deep‐Tissue Imaging under Continuous‐Wave Excitation with Tunable Upconverting Nanoparticles

Advanced Materials, EarlyView.
This study introduces a multimodal nonlinear microscopy approach using upconverting nanoparticles (UCNPs) under continuous‐wave excitation. The UCNPs exhibit high‐order nonlinear optical responses, enabling deep‐tissue 3D imaging, video‐rate wide‐field imaging, and depth‐selective photomodulation.

Leveraging Grain Boundary Effects for Nanostructured Electrode Layers in Symmetric Solid Oxide Fuel Cells

Advanced Materials Interfaces, EarlyView.
Nanocrystalline thin‐films of lanthanum chromite exhibit extraordinary properties of fast oxygen kinetics. These properties are due to the peculiar chemistry of grain boundaries and can be harnessed for fabricating symmetric electrochemical devices with self‐healing properties. Abstract While grain boundary engineering is attracting great interest as a

Optical coherence tomography quantifies gradient refractive index and mechanical stiffness gradient across the human lens

Communications Medicine
Background As a key element of ocular accommodation, the inherent mechanical stiffness gradient and the gradient refractive index (GRIN) of the crystalline lens determine its deformability and optical functionality.

Texture‐Enhanced Mechanical Stability of Transparent Electrodes for Flexible Optoelectronics with Near‐Infrared Response

Advanced Materials Interfaces, EarlyView.
Texturing of indium tin oxide (ITO) electrodes on plastic substrates is found to enable both, a remarkable transparency up to the near‐infrared region, and a massively enhanced mechanical stability upon bending. Therefore, textured ITO electrodes are an appealing option for flexible opto‐electronic applications with near‐infrared response, such as all ...

From Presbyopia to Cataracts: A Critical Review on Dysfunctional Lens Syndrome

Journal of Ophthalmology, 2018
Dysfunctional lens syndrome (DLS) is a term coined to describe the natural aging changes in the crystalline lens. Different alterations in the refractive properties and transparency of the lens are produced during the development of presbyopia and ...
