Ultrasonic Orbital Microforming—A New Possibility in the Forming of Microparts

Metals, 2018
The demand for very small metal parts is growing rapidly due to the development of micromechanisms. In microtechnology, the dimensions of scale parts are below 1 + c mm, where c varies based on the process type.

Orbital adipose tissue

Офтальмохирургия, 2016
We summarized the results of Russian and foreign researches elucidating embryogenesis, topography and anatomy of different orbital fat pads. It is interesting that adipose tissue from different surgical adipose spaces do not stem from the same germ ...

Pin Extrusion for Mechanical Joining from Orbital Formed Tailored Blanks with Local Material Pre-Distribution

Journal of Manufacturing and Materials Processing, 2022
Pin extrusion is a common process to realise pin structures in different geometrical dimensions for a subsequent joining operation. Nevertheless, the process of pin extrusion offers process limits regarding sheet thinning as a consequence of the punch ...

Investigation using single point incremental forming (SPIF) to fabricate patient-specific, titanium orbital floor implants [PDF]

MATEC Web of Conferences
The floor of the human orbit is composed of thin bone that is prone to traumatic fracture. This leads to a loss of support for the eye, which can cause vision changes. Therefore, fractures may need surgical reconstruction using a thin, sheet-like implant.

Bi-Doped Pd Aerogels with Tensile-Strain-Induced Cascade Orbital Hybridization Boost H2O2 Selective Activation for Efficient Pesticide Distinction [PDF]

Research
The selective activation of H2O2 into hydroxyl radicals (•OH) through the synergistic interplay between the nanozyme’s internal orbital interactions and external orbital coupling with intermediates presents an important scientific challenge.

Fat-forming solitary fibrous tumor of the orbit with typical imaging findings

American Journal of Ophthalmology Case Reports
Purpose: We describe a case of fat-forming solitary fibrous tumor (SFT) of the orbit with typical findings on imaging that may improve the awareness of orbital fat-forming SFT.

The JCMT BISTRO Survey: Magnetic Fields Align with Orbital Structure in the Galactic Center [PDF]

The Astrophysical Journal Letters
We present the magnetic field in the dense material of the Central Molecular Zone (CMZ) of the Milky Way, traced in 850 μ m polarized dust emission as part of the James Clerk Maxwell Telescope B -fields in STar-forming Region Observations survey.

Planetesimal Accretion at Short Orbital Periods

The Astrophysical Journal, 2023
Formation models in which terrestrial bodies grow via the pairwise accretion of planetesimals have been reasonably successful at reproducing the general properties of the Solar System, including small-body populations. However, planetesimal accretion has

Coulomb localization in orbital degenerate, doped Mott insulators [PDF]

AIP Advances, 2018
We study electron localization in a three-band extended Hubbard model describing the t2g electrons of doped vanadium perovskites such as La1−xCaxVO3, where Ca defects are represented by Coulomb potentials.
