Impact response of aluminum corrugated core sandwich panels

open access: yesInternational Journal of Impact Engineering, 2013
AbstractThe mechanisms of projectile penetration of extruded 6061T6 aluminum alloy sandwich panels with empty and alumina filled, triangular corrugated cores have been experimentally investigated using zero obliquity, 12.7 mm diameter hard steel projectiles whose diameter was about a half that of the core's unit cell width.

CLASP Constraints on the Magnetization and Geometrical Complexity of the Chromosphere-Corona Transition Region

open access: yes, 2018
The Chromospheric Lyman-Alpha Spectro-Polarimeter (CLASP) is a suborbital rocket experiment that on 3rd September 2015 measured the linear polarization produced by scattering processes in the hydrogen Ly-$\alpha$ line of the solar disk radiation, whose ...

Surface Properties of CeB6 and Challenges in Surface Preparation Revealed by Scanning Tunneling Microscopy

open access: yesAdvanced Physics Research, EarlyView.
The investigation of the Kondo lattice system CeB6${\rm CeB}_6$ by highly surface sensitive techniques is hampered by difficulties in preparing well‐ordered, atomically flat surfaces. The richness of possible surface terminations and their impact on spectroscopic STM results are discussed.

Two Distinct Phases of Bilayer Graphene Films on Ru(0001) [PDF]

open access: yes, 2012
By combining angle-resolved photoemission spectroscopy and scanning tunneling microscopy we reveal the structural and electronic properties of multilayer graphene on Ru(0001). We prove that large ethylene exposure allows to synthesize two distinct phases

Mechanistic Origins of Structural Failure in Deeply‐Lithiated LixMoS2

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Global optimization and ab initio molecular dynamics reveal how Li drives the 2H to 1T′ phase transformation in MoS2 and where the layered framework begins to fracture. Controlled pre‐lithiation stabilizes 1T′ and significantly delays the onset of structural failure, while opening out‐of‐plane Li pathways, offering design rules for robust, high‐rate ...

Electron density distribution and screening in rippled graphene sheets [PDF]

open access: yes, 2010
Single-layer graphene sheets are typically characterized by long-wavelength corrugations (ripples) which can be shown to be at the origin of rather strong potentials with both scalar and vector components. We present an extensive microscopic study, based

Germanium‐Based Mid‐Infrared Integrated Photonics

open access: yesLaser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Development of high-speed directly-modulated DFB and DBR lasers with surface gratings [PDF]

open access: yes, 2011
The conventional distributed feedback and distributed Bragg reflector edge-emitting lasers employ buried gratings, which require two or more epitaxial growth steps.

Development of Vertical Wind Turbine Blades Using 4D Printing of Composites

open access: yesPolymer Composites, EarlyView.
Vertical axis wind turbine: White blade: Commercial. Black blade: Composite. ABSTRACT This paper presents the procedure to make vertical wind turbine blades using the technique of 4D printing of composites (4DPC). The blades are made using carbon/epoxy composite materials with a fiber volume fraction of about 60%.
