Front Cover: A novel conceptual material and design of magneto-responsive shape-memory polyurethane (SMP) foam composites with excellent stability reversibility is introduced by Mohammadreza Lalegani Dezaki Mahdi Bodaghi in article 2200490. They are lightweight, stable, shape-recoverable, soft, programmable expected to be game changer the soft robotics field.

Abstract Recent years have seen major advances in the additive manufacturing of stimuli‐responsive materials, also known as “4D printing,” among which liquid crystal elastomers (LCEs) play an important role. However, during fabrication photo‐crosslinking LCEs is required, but this step time‐consuming and efficient polymerization challenging, especially case light‐responsive materials. In work, ...

Moisture-responsive materials are gaining greater interest for their potentially wide applications and the readily access to moisture. In this study, we show the fabrication of moisture-responsive, self-standing films using sustainable cellulose as starting material. Cellulose was modified by stearoyl moieties at first, leading to cellulose stearoyl esters (CSEs) with diverse degrees of substit...

Rheumatoid arthritis (RA) is an autoimmune disease characterized by progressive cartilage and bone destruction. Activated macrophages that overexpress folic acid (FA) receptors play an important role in RA, due to their abundance in inflamed synovial membrane and joints. In an effort to deliver drugs to the inflamed tissues, multifunctional FA receptor-targeting and pH-responsive nanocarriers w...

Biodegradable, stimuli-responsive polymers are essential platforms in the field of drug delivery and injectable biomaterials for application of bone tissue engineering. Various thermo-responsive hydrogels display water-based homogenous properties to encapsulate, manipulate and transfer its contents to the surrounding tissue, in the least invasive manner. The success of bioengineered injectable ...

Background: Sunflower (Helianthus annuus L.) is one of the important vegetable oil supplies in the world and in Iran, as well. It is classified as a drought semi-tolerant crop; however, its yield is adversely affected by drought stress. Understanding the initial events in sensing stress and the related physiologic and biochemical events thereafter, is crucial in designing droug...

Inspired by the fascinating working process of living systems, materials that can respond to external stimuli (mechanical, chemical, optical changes in environmental conditions, etc.) are of enormous interest owing to their applications in a wide range of fields including microfluidic devices, drug delivery, tissue engineering, sensors and actuators. This review, while being non-exhaustive in l...
