Results of research on determining the coefficient of rolling resistance of the wheel by the rollback method

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
AbstractThe simultaneous rolling process of two identical wheels in the driving and braking modes is simulated, taking into account the rollback process. The processes of interaction of the driving and braking wheels of the same size with each other and with the mobile platform (road) separating them are studied.

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

open access: yesAdvanced Materials, EarlyView.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Engineered Protein‐Based Ionic Conductors for Sustainable Energy Storage Applications

open access: yesAdvanced Materials, EarlyView.
Rational incorporation of charged residues into an engineered, self‐assembling protein scaffold yields solid‐state protein films with outstanding ionic conductivity. Salt‐doping further enhances conductivity, an effect amplified in the engineered variants. These properties enable the material integration into an efficient supercapacitor.
