MoNb 6 O 18 having a Wadsley–Roth shear crystal structure was explored as new anode material for lithium-ion storage.

This paper describes how, based on a method originated by Raghavan and Roth and elaborated by Mavroidis and Roth, a systematic approach is defined in order to obtain and solve the input-output equations of any overconstrained mechanism. We show that the key to study overconstrained mechanisms lies in analyzing a certain matrix. We are using this matrix to prove overconstraint of special structu...
