Design of high-perveance confined-flow guns for periodic-permanent-magnet-focused tubes [PDF]
An approach to the design of high perveance, low compression guns is described in which confinement is used to stabilize the beam for subsequent periodic-permanent-magnet focusing. The computed results for two cases are presented.

Magnetic Aftereffect of Sm2(Fe0.8Co0.2)N3.03 Compression Bonded Magnet.
Journal of the Japan Society of Powder and Powder Metallurgy, 1995 The magnetic field and temperature dependences of the magnetic aftereffect constant Sv were examined for the Sm2(Fe0.8Co0.2)17 N3.03 compression bonded magnet at a temperature range from 77 to 397K. Sv increases gradually with increasing the magnetic field.

Digital Actuation Control of Soft Robotic Origami With Self‐Folding Liquid Crystal Elastomer Hinges
Advanced Functional Materials, EarlyView.Self‐folding soft‐rigid hybrid robotic origami is enabled by liquid crystal elastomer actuators with embedded Joule heating and closed‐loop digital control. Digitally addressable hinges provide reversible and programmable transitions between distinct folded states while maintaining actuation performance at high cycle counts (over 1500).

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer
Advanced Functional Materials, EarlyView.Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Magnetic Aftereffect of Nd-Fe-Co-B-V Compression Bonded Magnets.
Journal of the Magnetics Society of Japan, 1992 Compression bonded magnets were manufactured using melt-spun ribbons of Nd 11 Fe 72 Co 8 B 7.5 V 1.5 , MQP-B and MQP-D (GM Co., Ltd.). The magnetic field and temperature dependences of the magnetic aftereffect constant (S v ) which determines the magnetic stability were studied. Compared with bonded magnets based on MQ powders, Nd 11 Fe 72 Co 8 B 7.5 V

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration
Advanced Functional Materials, EarlyView.Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.
