Convective heat transfer coefficient for indoor forced convection drying of vermicelli

IOSR Journal of Engineering, 2012
In this present research paper, an attempt has been made to determine the convective heat transfer coefficient of vermicelli under indoor forced convection drying mode. The experiments were conducted in the month of March 2012 in the climatic conditions of Rohtak (28 o 40’: 29 05’N 76 o 13’: 76 o 51’E). Experimental data was used to evaluate the values

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses
