Synthesis and doping of nickel and zinc tungstate with group 11 elements for the analysis of photocatalytic properties [PDF]
, 2019 This study presents two metal tungstates, nickel (NiWO4) and zinc (ZnWO4), modified with silver and copper respectively. It has been found that doping of nickel tungstate with silver was not possible through coprecipitation methods due to a dopant ...

"The Real Thing:" Nominal Price Rigidity of the Nickel Coke, 1886-1959 [PDF]
We report that the price of a 6.5oz Coke was 5¢ from 1886 until 1959. Thus, we are documenting a nominal price rigidity that lasted more than 70 years!
