While bulk bismuth (Bi) is a semimetal, we have found clear evidence of superconductivity in 72 nm diameter crystalline Bi nanowire below 1.3 K. In a parallel magnetic field (H), the residual resistance of the nanowire below T(c) displays periodic oscillations with H, and the period corresponds to a superconducting flux quantum. This result indicates that the superconductivity originates from t...

In this paper we use mono- and bi-metallic complexes, based on earth-abundant, cheap benign zinc, for the synthesis of sustainable aliphatic semi-aromatic polyesters. Tridentate hexadentate aldimine-thioetherphenolate ligands...

The introduction of small quantities tertiary base metals into supported AuPd nanoparticles is found to result in improved catalytic performance towards the direct synthesis H 2 O compared bi-metallic analogue.

Using wideband (0.5–6.5 eV) spectroscopic ellipsometry, we study ultrathin [Bi(0.6–2.5 nm)–FeNi(0.8,1.2 nm)]N multilayer films grown by rf sputtering deposition, where the FeNi layer has a nanoisland structure and its morphology magnetic properties change with decreasing nominal thickness. From model simulations of ellipsometric angles, Ψ(ω) Δ(ω), complex (pseudo)dielectric function spectra Bi ...

Ultra-low coefficient of thermal expansion (CTE) is an elusive property, and narrow temperature ranges of operation and poor mechanical properties limit the use of conventional materials with low CTE. We structured a periodic micro-array of bi-metallic cells to demonstrate ultra-low effective CTE with a wide temperature range. These engineered tunable CTE thin film can be applied to minimize th...

With its low abundance in the Earth’s crust and high mining costs, metallic tellurium (Te) is a limited resource. In advanced material industries, it irrecoverable from solid wastes. Hence, we investigated hydrothermal treatment of Bi–Te intermetallic alloy (BT-alloy) to develop an eco-friendly resource recovery technique for recovering Te. High-purity (∼100 mass %) Te powder can be directly re...
