Production of S7 tool steel powders by water atomization for laser powder bed fusion and directed energy deposition additive manufacturing

Materials & Design
The vast majority of powders used in additive manufacturing (AM) are produced by gas atomization. This process generates metal powders typically made of spherical particles that are exempt from significant oxidation products.

Visualization of Atomization Gas Flow and Melt Break-up Effects in Response to Nozzle Design [PDF]

, 2011
Both powder particle size control and efficient use of gas flow energy are highly prized goals for gas atomization of metal and alloy powder to minimize off-size powder inventory (or 'reverb') and excessive gas consumption.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Interactions of rare gas cations with lighter rare gas atoms

Molecular Physics, 2010
High-level ab initio calculations are employed to generate potential energy curves for rare gas cations, RG+, interacting with neutral atoms of other rare gases, RG', that are lighter (RG+/RG' = Ne-Rn). The calculations employ the RCCSD(T) method, with doubly-augmented basis sets of quintuple-zeta quality.

Simulation of powder metal fabrication with high pressure gas atomization [PDF]

, 1994
A computational/analytical technique has been developed which models the physics of high pressure gas atomization. The technique uses an uncoupled approach, such that the gas flowfield is initially calculated with a commercially-available Navier-Stokes ...

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

Advanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...
