Tailoring SHG Efficiency via t‐Te Nanocrystals in Tellurite Glasses by Femtosecond Laser Micromachining

open access: yesLaser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
Femtosecond laser irradiation at the glass surface induces symmetry breaking and crystallization of triclínic t‐Te nanophases, enabling intense second‐harmonic generation (SHG). The illustration depicts the fs‐pulse interaction, structural rearrangement, and nonlinear activation from amorphous tellurite glass to crystalline regions.

Buckling of corrugated core sandwich panels

open access: yes, 1969
A computer program is developed to determine the buckling stress and deflections of symmetric corrugated core sandwich panels. In the program freedom for lateral deflections at core to face-plate junction is allowed for. Provision is also made to study the effect of variation of core bend radius.

Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

open access: yesMetalMat, Volume 3, Issue 1, March 2026.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.

Evaluation of advanced regenerator systems [PDF]

open access: yes
The major considerations are discussed which will affect the selection of a ceramic regenerative heat exchanger for an improved 100 HP automotive gas turbine engine. The regenerator considered for this application is about 36cm in diameter.

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles

open access: yesJournal of Field Robotics, Volume 43, Issue 2, Page 1068-1090, March 2026.
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...

Spontaneous Intercalation of Graphene on Sapphire

open access: yesSmall Methods, Volume 10, Issue 5, 9 March 2026.
When left at room temperature, even in depressurized atmosphere, foreign molecular species can intercalate in between graphene and the (31$\sqrt {\mathbf {31}}$×$\times$31$\sqrt {\mathbf {31}}$)R9∘$^{\circ }$ reconstruction, effectively decoupling the graphene from its substrate: αAl2O3$\alpha {\rm Al}_2{\rm O}_3$(0001).

Acoustic tests of augmentor wing model [PDF]

open access: yes
Acoustic and aerodynamic data were obtained for a full-scale section of an augmentor wing. Features of the design included a single-row, multielement nozzle array and acoustically tuned panels placed on the interior surfaces of the augmentor.
