Zhang, Yuqi (author), Kaiser, Elias (author), Dutta, S. (author), Sharkey, Thomas D. (author), Marcelis, Leo F.M. (author), Li, Tao (author)

Triose phosphate utilization (TPU) limitation is one of the three biochemical limitations of photosynthetic CO₂ assimilation rate in C₃ plants. Under TPU limitation, abrupt and large transitions in light intensity cause damped oscillations in photosynthesis. When plants are salt-stressed, photosynthesis is often down...

Experimental studies on the impact of adsorbent particle size on the adsorption chiller performance

Manila, R.M. (author), Srinivasan, Kandadai (author), Dutta, Pradip (author)

Adsorption chiller dynamics and its effect on the performance are greatly influenced by the adsorbent particle size because they govern both the micro (intra-particle) and macro (inter-particle) heat and mass transfer resistances within the adsorber bed. The net effect of adsorbent particle size and shape on the overall cooling system...

The effect of nano-sized κ-carbides on the mechanical properties of an Fe-Mn-Al-C alloy

Banis, Alexandros (author), Gomez, Andrea (author), Dutta, Aniruddha (author), Sabirov, Ilchat (author), Petrov, R.H. (author)

The strengthening via precipitation of nano-sized κ-carbides leads to exceptional strength-ductility balance in low-density steels. During aging, such nanocarbides form through spinodal decomposition by fluctuations in the aluminum and carbon content in the austenite, followed by short-range ordering. At lower aging temperatures and short...

Since its first emergence in 2004, the high-entropy alloy (HEA) concept has aimed at stabilizing single- or dual-phase multi-element solid solutions through high mixing entropy. Here, this strategy is changed and renders such massive solid solutions metastable, to trigger spinodal decomposition for improving the alloys’ magnetic properties....
