Experimental characterization of the thrust induced by laser ablation on an asteroid

open access: yes, 2013
This paper presents an improved laser ablation model and compares the performance – Δv and mass efficiency - of laser ablation against contactless deflection methods based on ion-propulsion.

Pistol bullet deflection through soft tissue simulants.

open access: yes, 2018
Trajectory deflections of pistol bullets from four different firearms, fired through soft tissue simulants under two different incidence and exit angles were studied.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Airstream Deflection Across a Cylindrical Surface

open access: yes, 2016
A cylindrical airstream was blown across a cylindrical surface. The deflection angle, peak speed, and asymmetry of the airstream were measured while changing the location of the cylinder relative to the center of the wind column, and while changing the ...

Synergistic approach of asteroid exploitation and planetary protection

open access: yes, 2012
The asteroid and cometary impact hazard has long been recognised as an important issue requiring risk assessment and contingency planning. At the same time asteroids have also been acknowledged as possible sources of raw materials for future large-scale ...

Deflection and translation of a ray traversing an optical system, nodal rays and the optical axis

open access: yesAfrican Vision and Eye Health, 2009
Expressions are derived for the deflection and transverse translation of a ray as it traverses an arbitrary optical system.  The system may be astigmatic and have relatively decentred refracting elements.

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

open access: yesAdvanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Effect of eddy current in shielding plate and electron gun on flux distribution in CRT [PDF]

open access: yes, 2002
The eddy current induced in an inner magnetic shield (IMS) and an electron gun affect the flux distribution of a cathode ray tube, causing a possible degrade of picture quality.

Marat and the Deflection of Light [PDF]

open access: yesNature, 1920
CARLYLE'S vivid portraiture of Marat as “horse-leech” and savage revolutionist has rather obscured the fact that this “friend of the people” was a learned doctor of medicine, a physicist, and a physiologist. It is true that Carlyle refers to him as “Renovator of Human Science, Lecturer on Optics,” but the mistake about the “horse-leech” is repeated in ...
