Analytical modelling for prediction and prevention of overflow occurrence in wire-based additive manufacturing

open access: yesVirtual and Physical Prototyping
Increasing deposition rate is essential for higher productivity of additive manufacturing (AM). However, a high deposition rate usually requires high heat input to fully melt the fast-fed material, which could lead to defects due to molten material ...

Influence of high heating rates on evolution of oxides on directed laser energy additively fabricated IN718

open access: yesnpj Materials Degradation, 2021
The effect of non-isothermal treatment in oxygen-containing air, via heating rates of 10, 50, and 1000 °C/min until 1000 °C followed by furnace cooling to room temperature on oxides formed on directed laser energy additively fabricated IN718 was studied.

3D Printing Using Ti-Al Nanopowders: Mechanisms of Structure Formation

open access: yesMetals, 2022
In the presented research work, 3D materials were fabricated by additive moulding by means of extrusion of a mixture of high filled polymers and nanopowders of Ti-Al intermetallides with subsequent sintering at 1100 ± 20 °C, 1200 ± 20 °C and 1250 ± 20 °C

4D printing of shape-programmable polymer-derived ceramics via two-stage folding-assisted pyrolysis strategy

open access: yesVirtual and Physical Prototyping
Polymer-derived ceramics (PDCs) can be used in wide applications due to their high hardness and stable chemical properties. However, these characteristics lead to the challenging controllable deformation of additively manufactured PDCs.

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Quantum Fourier addition simplified to Toffoli addition

open access: yesPhysical Review A, 2022
Quantum addition circuits are considered being of two types: 1) Toffolli-adder circuits which use only classical reversible gates (CNOT and Toffoli), and 2) QFT-adder circuits based on the quantum Fourier transformation. We present the first systematic translation of the QFT-addition circuit into a Toffoli-based adder.
