Reconfigurable Metamirrors Based on Compliant Mechanisms
Advanced Functional Materials, EarlyView.Providing the basis for numerous practical applications, the reconfigurability of metadevices is of great importance. Through the integration of controlled mechanical deformation with chiral meta‐atoms, a compliant mechanism based metamirror is demonstrated for active control over the polarization of electromagnetic waves.

Localized flexural bullous pemphigoid
Indian Journal of Dermatology, 2008 A 63-year-old male agriculturist presented with a spontaneously appearing bullous eruption localized to the axillae and groins, with intense pruritus of 3 weeks duration. He was also a known hypertensive, diagnosed with renal failure on treatment with ACE inhibitors and amlodepin since 1 year.

Mechanical Behavior of Concrete Modified by Replacement of Cement by Rice Husk Ash
Brazilian Archives of Biology and TechnologyConstruction industry is in need of lump sum quantities of materials which has increased both their demand and price. The use of large quantities of cement leads to increasing CO2 emission and as a consequence, the greenhouse effect.

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment
Advanced Functional Materials, EarlyView.Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers
Advanced Functional Materials, EarlyView.Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...
