A generalized method for multiple robotic manipulator programming applied to vertical-up welding [PDF]

open access: yes
The application is described of a weld programming algorithm for vertical-up welding, which is frequently desired for variable polarity plasma arc welding (VPPAW).

Superior Abrasibility of YSZ(ESP)/BN@ZrO2‐Polyester Composite Sealing Coating Reinforcing With Hybrid Micron/Nanometer Multiscaled Pore Structure

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

Heat sink effects in variable polarity plasma arc welding [PDF]

open access: yes
The Space Shuttle External Tank is fabricated by the variable polarity plasma arc (VPPA) welding process. In VPPA welding, a noble gas, usually argon, is directed through an arc to emerge from the torch as a hot plasma jet.

Spectroscopic Signatures of Doping in Thin Films of Semiconducting Single‐Walled Carbon Nanotubes

open access: yesSmall, Volume 22, Issue 28, 18 May 2026.
This review presents an overview of the spectroscopic changes of semiconducting single‐walled carbon nanotubes upon chemical, electrochemical or electrostatic doping. The presence of holes or electrons directly affects visible to far‐infrared absorption, near‐infrared fluorescence and electroluminescence as well as Raman spectra, which enables in‐situ ...

HRTEM Imaging and Mechanistic Insights Into Carbon Nanotube Nucleation and Growth on Fe Nanocatalysts in a Thermal Plasma

open access: yesSmall Methods, Volume 10, Issue 9, 8 May 2026.
Carbon nanotubes (CNTs) were successfully debundled from Tuball soots produced using iron nanocatalysts in arc discharge thermal plasma and distributed on monolayer graphene for HRTEM imaging for mechanistic insights into CNT synthesis. Zigzag single‐wall or double‐wall CNTs were identified.

Chemical Geodynamics of Granitoid Magmatism During a Pacific‐Philippine Sea Plate Transition in Southwest Japan

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Granitoid magmatism along the western Pacific margin records interactions between subduction dynamics and crust–mantle processes; however, the links between plate reorganization and magma‐source evolution remain debated. Here we integrate U–Pb zircon geochronology with Pb–Sr–Nd–Hf isotope systematics to investigate Cretaceous–Paleogene ...

Characterization of a 50kW Inductively Coupled Plasma Torch for Testing of Ablative Thermal Protection Materials [PDF]

open access: yes
With the development of new manned spaceflight capabilities including NASA's Orion capsule and the Space-X Dragon capsule, there is a renewed importance of understanding the dynamics of ablative thermal protection systems.
