Atomic-scale mechanisms of defect- and light-induced oxidation and degradation of InSe
Published 2020“…Moreover, under ambient conditions, the splitting of O2 enables the formation of substitutional (apical) oxygen atomic species, which further cause the trapping and subsequent rapid splitting of H2O molecules and ultimately the formation of hydroxyl groups. …”

Three-dimensional modeling of near-field beam profiles from grating couplers using a deep neural network
Published 2024“…Integrated silicon photonics (SiPh) gratings have been widely studied for the optical addressing of trapped ions. As the formfactor of ion traps reduces, the ion-trapping height decreases, and may unavoidably fall into the reactive near-field region of SiPh gratings. …”

Modeling of functional materials : perovskite solar cells
Published 2014“…However, for a more holistic analysis of perovskite light harvesters as replacement to the existing TiO2 nano particles, a more nuanced modeling and analysis which incorporates a study of transport properties such as trapping effects (for further spike in efficiency), photo catalytic reaction kinetics and surface & bulk defects (for easier fabrication) is demanded as an integral part of future research plans.…”

Delocalized Davydov D1 Ansatz for the Holstein polaron
Published 2013“…Unique solutions are obtained with the delocalized D1 for different initial conditions when the transfer integral is 20 times the phonon frequency at the zone center, implying the absence of any self-trapping discontinuity. The scaled correlation variance is found to fit satisfactorily well with the predictions of the perturbation theories.…”

Characterising the iron dependence of T-cells
Published 2023“…Interestingly, exogenous aspartate substantially rescues the proliferation of iron deprived CD8+ T-cells suggesting that endogenous aspartate sources are unusable, possibly due to trapping of aspartate within the mitochondria. Overall, this thesis demonstrates that iron deprivation impairs T-cell biochemistry at multiple nodes providing insight as to how metabolic and iron modulatory interventions could be coupled to augment or suppress immunity.…”

Influence of calcination temperature on nickel oxide nanoparticles synthesized by thermal treatment
Published 2015“…In the present work, crystalline nickel oxide (NiO) nanoparticles have been synthesized using a simple thermal treatment method from a well-mixed solution containing only nickel nitrate as a metal precursor, polyvinyl pyrrolidone as a capping agent, and deionized water as a solvent before proceeded by drying at 80 oC for 24 h, grounding, and calcination at different temperatures range from 500 to 800 oC. …”

Experimental investigation on the effect of masked multiple passes abrasive waterjet machining surface texturing on coefficient of friction
Published 2025“…According to the findings, there is less friction in craters with greater densities because there are more craters in the contact zone, which improves the trapping of debris particles and reduces friction, when the crater density rises from 4% to 18%, there is a greater chance of worn debris becoming trapped, which reduces friction. …”

Molybdenum disulfide (MoS_2) as a broadband saturable absorber for ultra-fast photonics
Published 2014“…To explore its potential applications in ultrafast photonics, we fabricated a passive mode locker for ytterbium-doped fibre laser by depositing few-layered MoS2 onto the end facet of optical fiber by means of an optical trapping approach. Our laser experiment shows that few-layer MoS2-based mode locker allows for the generation of stable mode-locked laser pulse, centered at 1054.3 nm, with a 3-dB spectral bandwidth of 2.7 nm and a pulse duration of 800 ps. …”
