Isotope Effect and Isotope Separation

Nippon kagaku zassi, 1968
同位体物質の換算分配関数比の値を, 量子統計論に基づき, 分子振動スペクトルからの知見を用いて算定した。これらの結果は同位体分離の研究に一つの基礎を与える。同位体物質が二相に分配するとき, 化学反応が同位体の分離効果にどのような影響をおよぼすかについて理論的な考察(二相分配理論) を行なった。導出された基礎式から, どのような系がもっとも分離効果が大きいかを知ることができる。二三の簡単な系について, この理論を展開した。さらにイオン交換樹脂を用いて, 実際にリチウム, 窒素, 銅, ウラン同位体の分離実験を行ない, 相分配理論によって解析を試みた。

Isotopically Selected Co‐Doping of 121Sb and 123Sb Pairs in Silicon

Advanced Materials, EarlyView.
Pairs of 121Sb and 123Sb atoms are doped into silicon using single cluster implantation and found to reside substitutionally within the crystal lattice due to self‐annealing with a Sb‐to Sb separation of ≈2 nm. Molecular dynamics simulations reproduce the observed experimental results and single ion cluster detection efficiencies of 94% are ...

Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

Advanced Materials, EarlyView.
Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.

Phonon Engineering in Ultrathin Sn Films

Advanced Materials Interfaces, EarlyView.
When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the

New Directions in Focused Ion Beam Induced Deposition for the Nanoprinting of Functional 3D Heterostructures

Advanced Materials Technologies, EarlyView.
Here, it is shown that focused ion beam induced deposition (FIBID) using helium and neon ions enables advanced high‐resolution 3D nanoprinting achieving precise multimaterial architectures and engineered internal voids. Thus, FIBID with finely focused noble gas ion species is presented as a unique platform for designing functional nanomaterials for ...

Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

Advanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...
