REEs are a series of chemical elements found in the Earth’s crust that are essential components of many technologies, including electronics, computer and communication systems, transportation, health care, and national defense. Rare Earths Elements (REE) are incorporated into many sophisticated technologies with both commercial and defense applications including smartphones and …

The emerging field of soft robotics aims to improve robot/human interactivity promising to bring robots into all aspects our daily lives, including wearable robotics, surgical robots, micromanipulation, search and rescue, and others. Soft robotics differ from traditional counterparts in some important ways: Soft robots have little or no hard internal …

The  discovery of topological materials whose properties  remain intact even when an object is stretched, twisted or deformed, led to the awarding of the Nobel Prize in physics in 2016 to F. Duncan M. Haldane,  and others. Their topological nature means these states are resistant to change, and so stable …

Increasing energy demand, environmental issues and limited availability of fossil fuels are demanding the research on sustainable and renewable energy resources. The sun is ultimate source to accomplish clean energy demand and photovoltaics, also known as solar PV, have been growing exponentially to harness it. The global solar photovoltaics (PV) …

The function of the propulsion system is to produce thrust, which is the force that moves a rocket through air and space. Different propulsion systems generate thrust in different ways, but always through some application of Newton’s third law of motion. In any propulsion system, a working fluid is accelerated …

Armor is a protective covering that is used to prevent damage from being inflicted to an object, individual or vehicle by direct contact weapons or projectiles, usually during combat, or from damage caused by a potentially dangerous environment or activity (e.g., construction sites, cycling, etc.). Personal armor is used to …

According to the International Air Transport Association (IATA), the demand for air travel rose by 7.4% in 2018 from 2017 levels. Air passengers accounted for 81.9% of the load factor on aircrafts, while freight load was 49.3%, the IATA data reveals. However, the COVID-19 pandemic has created turmoil in the …
