The inescapable need for sustainable supply chains has fascinated controversial attention, in the last two decades, due to increasing governmental regulations and societal awareness. But, facilities and their linkages, within the supply chain network, are subject to perturbations due to natural or human-made events (e.g., strikes and floods). Therefore, managers are concerned about re-engineering a supply chain network that is simultaneously sustainable and resilient. Hence, there is an inevitab...

MIT's Kulik Lab has designed better ways of discovering and designing novel, environmentally benign, and energy-efficient materials for energy applications in a vast chemical space where molecular combinations that offer remarkable optical, conductive, magnetic, and heat transfer properties await discovery.

Objective. Although in heavy-ion therapy, the quantum molecular dynamics (QMD) model is one of the most fundamental physics models providing an accurate daughter-ion production yield in the final state, there are still non-negligible differences with the experimental results. The aim of this study is to improve fragment production in water phantoms by developing a more accurate QMD model in Geant4. Approach. A QMD model was developed by implementing modern Skyrme interaction parameter sets, as w...

Explosion threat has a devastating impact on buildings, warships, vehicles and human lives, which puts forward urgent requirements for the development of explosion protection systems. In this study, a sandwich protection system against close-range blast loads containing graded re-entrant circular (REC) auxetic core was proposed, and its blast-resistance performance was investigated based on the numerical methods validated by the field blast test results in the literature. Numerical results showe...

Improving the performance of direct contact membrane distillation (DCMD) for liquid desiccant regeneration has attracted increasing attention. This paper presents multi-objective optimization of a DCMD regenerator to maximize its regeneration capacity (RC) and thermal efficiency (TE) simultaneously when treating a 25–30 wt.% lithium chloride desiccant solution. The key parameters, including initial feed concentration, feed and distillate inlet temperatures and volumetric flow rate were optimiz...

Ocean engineers and mechanical engineers at MIT, including Wim van Rees, Michael Benjamin, and Pierre Lermusiaux, are utilizing advances in scientific computing to address the ocean’s many challenges, and seize its opportunities.

In this research work, a novel disc-type configuration of magneto-rheological brake (MRB) with zigzag magnetic flux path is proposed. In this design, a rotor component consisting of several magnetic plates integrated in a disc made of non-magnetic material is implemented. A magnetic plate is separated with the others by nonmagnetic separators of the disc. Corresponding magnetic plates and separators are also implemented on the housing of the MRB. With this configuration, the magnetic flux line i...
