A series of full Heusler alloys, ${\text{Fe}}_{2}{\text{V}}_{1\ensuremath{-}x}{\text{W}}_{x}\text{Al}$, $0\ensuremath{\le}x\ensuremath{\le}0.2$, was prepared and characterized, and relevant physical properties to account for the thermoelectric perfor

The recently proposed novel materials class called Weyl-Kondo semimetal (WKSM) is a time reversal invariant but inversion symmetry broken Kondo semimetal in which Weyl nodes are pushed to the Fermi level by the Kondo interaction. Here we explore whet

The type-I clathrates Ba8Cu5(Si,Ge,Sn)41 show promising thermoelectric (TE) properties. We investigated the influence of Sn substitution for Ge on the TE properties of Ba8Cu5Si6(Ge,Sn)35 samples prepared by the fast and economic melt–spinning techn

The promising high magnetocrystalline anisotropy of about K 1 > 0.4 MJ/m 3 has been derived for (Fe,Co) 2–3 B melt-spun ribbons leading to a potential candidate for novel hard magnetic applications. We present the microstructural and magnetic analy

Nano-grained CoSb3 was prepared by melt-spinning and subsequent spark plasma sintering. The phonon thermal conductivity of skutterudites is known to be sensitive to the kind and the amount of guest atoms. Thus, unfilled CoSb3 can serve as model compo

Recent theoretical studies of topologically nontrivial electronic states in Kondo insulators have pointed to the importance of spin-orbit coupling (SOC) for stabilizing these states. However, systematic experimental studies that tune the SOC paramete

The perspective of melt spinning–rapid quenching of a melt to produce nanocrystalline intermetallic clathrates is discussed, using main-group and transition-metal clathrates as examples. While melt spinning was originally developed for production o

The photoassisted modification of LDPE by VUV irradiation in a reactive trimethylsilane/ oxygen atmosphere was investigated. The modified LDPE surface was investigated by FT-IR, XPS, contact-angle measurements and electron microscopy. Attachment of a

A new method for the modification of polymer surfaces with phosphorus-containing groups is described. Films of polybutadiene were UV-irradiated in the presence of PBr 3 vapor as a photoreactive agent. After subsequent reaction with water under aerobi
