DESCRIPTION:Refreshments and cakes will be available! \n\nAbstract:\n\nLiq
 uid crystalline elastomers (LCEs) are a versatile class of functional mate
 rials exhibiting exceptional properties\, including large-stroke reversibl
 e actuation\, anomalous mechanical energy damping\, and reversible pressur
 e-sensitive adhesion. A defining feature of LCEs is their soft elasticity\
 , characterized by a plateau of low\, nearly constant stress during stretc
 hing\, slow stress relaxation\, and enhanced surface adhesion. This presen
 tation explores the potential of LCEs in actuator applications and highlig
 hts their intrinsic energy dissipation mechanisms\, particularly in revers
 ible adhesion.\n\nBiography:\n\nDr. Saed is a University Royal Society Fel
 low and a group leader at the Cavendish Laboratory\, University of Cambrid
 ge\, specializing in smart\, sustainable\, and stimuli-responsive polymers
 . His research spans new material design\, additive manufacturing\, vitrim
 ers\, adhesives\, and liquid crystalline elastomers (LCEs). Over a decade-
 long academic career\, Dr. Saed has made pioneering contributions to polym
 er science. During his PhD at the University of Colorado\, he played a cru
 cial role in overcoming synthesis challenges in LCEs\, introducing click c
 hemistry for scalable production. His dissertation led to seven publicatio
 ns and a US patent\, revolutionizing the field. As a postdoctoral research
 er at the University of Texas\, he expanded into 3D printing and microfabr
 ication\, developing a 4D printing technique for LCEs\, now widely adopted
 . This work resulted in three papers and another US patent. At Cambridge\,
  Dr. Saed has published over 30 original papers\, filed four patents\, and
  secured over £2 million in research funding. He co-founded Cambridge Sma
 rt Plastics Ltd\, serving as Chief Technical Officer\, to commercialize vi
 trimer technologies developed during his tenure. As of May 2025\, he has 4
 3 original papers\, 6 patents (3 granted\, 3 filed)\, 2\,900 citations\, a
 nd an H-index of 26. His research is featured in leading journals such as 
 Chemical Reviews\, Nature Communications\, and Advanced Materials.
