Tunable Plasmonic Response of Silver Nanoparticles Entangled in Detonation Nanodiamond Network via Colloidal Self‐Assembly

open access: yesAdvanced Materials Interfaces, EarlyView.
Detonation nanodiamonds form a network that entangles silver nanoparticles into stable nanocomplexes. The structure can fine‐tune and enhance plasmonic absorption through nearfield electromagnetic interactions but prevents silver particle aggregation. The study shows how the arrangement and concentration of particles affect light absorption, offering a

Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

open access: yesAdvanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Air Permeability of Undisturbed Soils

open access: yesAir Permeability of Undisturbed Soils
application/pdf 土壌の構造を乱さない採土試料について通気性の特性を研究した。充填試料との比較において,また透水性と比較しながら,さらに通気間ゲキの屈曲度を電気伝導度によって考察しながら,通気間ゲキの特性を次のようにまとめることができた。まず,土壌の通気性は透水性と同じように,ある圧力勾配の範囲内ではDarcy法則が適用でき,通気係数によって通気性を評価できることが実験的に確認された。また,空気間ゲキ率と通気係数の間にはそのままでは一定の関係が認め難いが,これは採土試料の状態では間ゲキ内に大気に開放されていない空気間ゲキが残されているためと考えられる。そこで,水で試料を飽和した後排水しながら開放状態をつくり,排水過程で空気間ゲキ率と通気係数の関係を求めた。その結果 ...

Multi‐Material Gradient Printing Using Meniscus‐enabled Projection Stereolithography (MAPS)

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
MAPS is a new vat‐free printing technique that utilizes programmed delivery of resin droplets with custom formulations to enable multi‐material gradient printing of 3D structures with user‐defined variations in mechanical stiffness, opacity, surface energy, cell densities, and magnetic properties. Abstract Light‐based additive manufacturing methods are
