The fine silt deposits of Jammu (J & K State, India) stretch all along the Siwalik foothills from Jammu to the Potwar Plateau in Pakistan. The post-Siwalik deposits, first discussed by de Terra and Paterson (1939), are attributed to wind action. The deposits termed as 'Potwar loessic silt' comprising sandy silt are essentially of late Quaternary age (75-18 ka) and are re-looked herein from the point of view of genesis and climatic significance. The sorting, skewness and kurtosis parameters of fine silts of Jammu suggest fluvial environment of the deposits wherein the water budget fluctuated. The weak pedogenesis of fine silts at certain intervals corroborate to periods of less or no sedimentation. The bivariant plot studies further suggest fluvial environment of deposition for the fine silt at Jammu, with regular fluctuations in the budget of river water that was perhaps in consonance with oscillations in the climate of the region.

We report the nonlinear optical response in VS2/rGO hybrid experimentally and theoretically in the strongly coupled regime for their potential application in optical limiting. The enhanced nonlinear response from hybrid is attributed to charge transfer.

We experimentally and theoretically demonstrate giant excited-state absorption and positive nonlinear refractive index in VS2/MXene nanohybrid for fs pulses. The hallmark result is attributed to direct charge transfer, and a benchmark optical limiter is fabricated.
