Ab initio Studies of the Possible Magnetism in BN Sheet by Non-magnetic Impurities and Vacancies [PDF]

, 2007
We performed first-principles calculations to investigate the possible magnetism induced by the different concentrations of non-magnetic impurities and vacancies in BN sheet. The atoms of Be, B, C, N, O, Al and Si are used to replace either B or N in the

Additive Manufacturing of Tailored Blank for Sheet-Bulk Metal Forming Processes [PDF]

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Functional integration and lightweight construction pose increasing demands on manufacturing processes and require innovative approaches. In this context, sheet-bulk metal forming combines the advantages of conventional sheet and bulk forming processes expanding the limitations of these particular processes.

Large diameter multiwall nanotubes of MgB2: structural aspects and stability of superconducting nanotubular magnesium boride

, 2015
Based on a theoretical study, we demonstrated that magnesium boride nanotubes can reach the same stability as bulk MgB2 structure. However, most stable nanotubular forms are not structurally derived from mixed triangular-hexagonal structural motifs of a ...

Transport behavior of holes in boron delta-doped diamond structures [PDF]

, 2013
Boron delta-doped diamond structures have been synthesized using microwave plasma chemical vapor deposition and fabricated into FET and gated Hall bar devices for assessment of the electrical characteristics. A detailed study of variable temperature Hall,

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Inverse form finding with h-adaptivity and an application to a notch stamping process [PDF]

, 2017
The aim is to determine the optimized semi-finished workpiece geometry to its given target geometry after a forming process. Hereby, a novel approach for inverse form finding, a type of a shape optimization, is applied to a notch stamping process.

DEEP LEARNING IN SHEET-BULK METAL FORMING PART DESIGN

Design Conference Proceedings, 2018
Within the Transregional Collaborative Research Centre 73, a self-learning engineering workbench is being developed. It assists product developers in designing sheet-bulk metal formed (SBMF) parts by computing the effects of given product and process characteristics on the product properties.
