The most interesting feature of sodium alginate is to undergo ionic gelation by the influence of various divalent and trivalent metal cations (such as, Ca2 +, Zn2 +, Ba2 +, Al3 +, etc.) in the aqueous milieu [73–75]. In recent years, various alginate-based nanocomposite scaffolds are...
Robots on the rise: Showing their metal mettle Since the first programmable robot design in 1954, much has happened but little has changed. While the first industrial robots were used in 1962 at a General Motors auto plant in New Jersey to spot-weld and extract die castings, nearly a half...
among which transition-metal sites with distinctdorbitals configuration and multiple redox states have attracted researchers’ interests. Principally speaking, the CO2-to-syngas conversion mainly involves the formation of a series of intermediates (i.e., *CO2, HCOO*,...
We outline the materials-design pathway from implementation strategy through selection of materials and fabrication methods to evaluation. Finally, we discuss unmet needs and current challenges in the development of ideal materials for bone-tissue regeneration and highlight emerging strategies in the field...

Both natural and synthetic hydrogels are broadly employed. The common natural polymers exploited for the fabrication of hydrogels are biodegradable materials such as fibrin, collagen, hyaluronic acid (HA), and alginate that can mimic natural tissue constructs. On the other hand, synthetic hydrogels suc...
