Modification of γ-alumina by barium and lanthanum, and the consequential effect on the reducibility and dispersibility of nickel
Shankar Narayanan,Kadiyala Uma +1 more
TL;DR: The influence of modifiers such as barium and lanthanum on the physical properties of γ-alumina has been studied in this paper, where it is assumed that the oxide layers over the surface of alumina prevent the interaction between nickel and γAl2O3, making more nickel available on the surface.
Journal ArticleDOI
The Role of Wettability on the Response of a Quartz Crystal Microbalance Loaded with a Sessile Droplet
Brandon Murray,Shankar Narayanan +1 more
TL;DR: This work develops a computational model that couples the electrical and mechanical analysis of the quartz substrate with the visco-acoustic behavior of the sessile droplet and concludes that changes in the contact angle have an effect on the frequency response of the QCM when the droplet height is on the order of the viscous decay length or smaller.
Journal ArticleDOI
Comparative investigation of hydrogen chemisorption and benzene hydrogenation activity of supported rhodium catalysts
TL;DR: In this paper, the dispersion and metal area decrease with metal loadings up to 3 wt.% of Rh on Al2O3, as does the turnover number (TON) for benzene hydrogenation.
Journal ArticleDOI
Size and shape-dependent electron–hole relaxation dynamics in CdS nanocrystals
Rupa Sarkar,Ajay Kumar Shaw,Shankar Narayanan,Carsten Rothe,S.I. Hintschich,Andy P. Monkman,Samir Kumar Pal +6 more
TL;DR: In this paper, the dynamics of photoluminescence in CdS nanocrystals (NCs) with various sizes and shapes dispersed in water-in-oil microemulsions (reverse micelles) are studied with picosecond-resolved time correlated single photon counting (TCSPC), streak camera and nanosecond resolved gated PL spectroscopic techniques.
Proceedings ArticleDOI
Experimental characterization of a micro-scale thin film evaporative cooling device
TL;DR: In this paper, a MEMS-NEMS cooling device based on gas-assisted thin-film evaporation and its experimental performance characterization is presented, aiming to dissipate large heat fluxes at low junction temperature for thermal management of hot spots in microprocessors.
