Cross Section Limits for the $^{208}$Pb($^{86}$Kr,n)$^{293}$118 Reaction

, 2002
In April-May, 2001, the previously reported experiment to synthesize element 118 using the $^{208}$Pb($^{86}$Kr,n)$^{293}$118 reaction was repeated. No events corresponding to the synthesis of element 118 were observed with a total beam dose of 2.6 x 10$^

Static and dynamic characteristics of a piezoceramic strut [PDF]

The experimental study of a piezoceramic active truss is presented. This active strut is unique in that the piezoceramic configurations allow the stroke length of the strut not to be dependent on the piezoceramic material's expansion range but on the ...

Composition‐Tuned Enhancement of the Anomalous Nernst Effect in FeCo–Pt Thin Films on Rigid and Flexible Substrates

Advanced Engineering Materials, EarlyView.
Disordered (Fe50Co50)1−xPtx thin films exhibit a pronounced anomalous Nernst effect (ANE) with a strong composition dependence on both rigid and flexible substrates. The transverse thermoelectric response peaks near 22.5 at.% Pt, accompanied by enhanced αxy/σxy scaling, thermal transport, and ANE sensitivity.

EVALUATION OF DEFORMATION CHARACTERISTICS OF SOIL BY BENDER ELEMENT TEST

Doboku Gakkai Ronbunshu, 2003
ベンダーエレメント試験 (以下BE試験) の受信波によって, 土の減衰振動ならびに共振を観察することができるという仮定に基づき, 共振法土質試験の理論を援用して2通りの方法でせん断弾性係数および減衰比を求める手法を示している. 粘土, 泥炭試料についての実験結果からこれらの方法によって求めたせん断弾性係数の値は, せん断波の到達時刻を受信波のピーク点で定義した場合よりは (試料によって3～7倍) 大きな値となること, また, 減衰比についてはBE試験による既往の報告例はないが, 繰返し三軸試験によって従来報告されている値と近いことを示している. これらの結果をふまえ, 従来の方法に加えて本研究で提案する2通りの方法を併用することにより, BE試験の活用範囲がさらに広がることを示唆している.

On the Influence of Antioxidants and Recycled MgO–C Source Material on the Mechanical Properties of Carbon‐Bonded Magnesia Refractories

Advanced Engineering Materials, EarlyView.
The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Constraints on galaxy formation from alpha-enhancement in luminous elliptical galaxies

, 1998
We explore the formation of alpha-enhanced and metal-rich stellar populations in the nuclei of luminous ellipticals under the assumption of two extreme galaxy formation scenarios based on hierarchical clustering, namely a fast clumpy collapse and the ...

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
