Shrimp shell waste obtained from Louisiana Gulf shrimp (Litopenaeus setiferus) was heat-treated at varying temperatures and ground into a powder by ball-milling. The powder was used with and without surface treatment with maleic anhydride or stearic

Nanoparticles of CuGaO 2 delafossite were successfully synthesized from the sol – gel process by controlling the atmospheric conditions at 850 °C. The average size of CuGaO 2 nanoparticles of ∼40 nm was determined by transmission electron micros

We report results of a muon spin rotation ($\ensuremath{\mu}\mathrm{SR}$) study of the cuprate-analog nickelate ${\mathrm{La}}_{4}{\mathrm{Ni}}_{3}{\mathrm{O}}_{8}$, which undergoes a transition at 105 K to a low-temperature phase with charge-stripe

This paper presents a facile synthetic procedure for p-type Mg2Si0.4Sn0.6 thermoelectric material. The B2O3 encapsulation method was used for synthesis, and Li2CO3 was used as the doping agent. These samples showed electrical conductivities and Seebe

A novel facile solvothermal fluorination method was developed for metastable oxyfluorides preparation by filling anion vacancies in parent structures. High solubility of XeF2 in acetonitrile and polarity of the solvent allowed for lower reaction temp

The new LiFeTiO 4 polymorph with the CaFe 2 O 4 -type (CF) crystal structure was synthesized via ion ex-change from NaFeTiO 4 . Due to the presence of tunnels sufficiently large to accommodate additional Li þ ions, CF-LiFeTiO 4 was studied as a mod

Delafossite CuAlO2 nanoparticles were prepared using an easily scalable method under controlled partial oxygen pressure (pO2) of 10−5 atm at 775 °C. Transmission electron microscopy showed a uniform particle size of 35 nm, agreeing well with the c

High Fe abundance in the Earth's crust, low and stable Fe price in comparison with other transitional metals, absence of toxicity or environmental concerns associated with Fe compounds led to very strong research and development efforts devoted to id
