Biological and Biologically Inspired Functional Nanostructures: Insights into Structural, Optical, Thermal, and Sensing Applications

open access: yesAdvanced Materials, EarlyView.
Biological and biologically‐inspired functional nanostructures with structural, thermal, optical, and sensing applications are reviewed. The role of nanoscale features in biological materials on performance is described, and their blueprints are used for bio‐inspired nanomaterials, synthesized using advanced techniques (i.e., photolithography, bio ...

Physical Intelligence in Small‐Scale Robots and Machines

open access: yesAdvanced Materials, EarlyView.
“Physical intelligence” (PI) empowers biological organisms and artificial machines, especially at the small scales, to perceive, adapt, and even reshape their complex, dynamic, and unstructured operation environments. This review summarizes recent milestones and future directions of PI in small‐scale robots and machines.

Boosting Mechanoluminescence Performance in Doped CaZnOS by the Facile Self‐Reduction Approach

open access: yesAdvanced Materials, EarlyView.
Self‐reduction primarily enhances mechanoluminescence intensity by deliberately introducing lattice defects, which increase structural distortion and amplify the piezoelectric response, thereby improving the force‐to‐light conversion efficiency. Additionally, self‐reduction optimizes the local distribution of Mn2+ ions, promoting energy concentration ...

Dynamic Navigation-Assisted Calcified Root Canal Therapy In Maxillary Incisor

open access: yesInternational Dental Journal
Introduction: Calcified root canal represents a troublesome problem in root canal therapy. Especially for diseased teeth accompanied by periapical periodontitis, whether root canal could be successfully dredged is key for curative effects.

A Pseudo‐Mytilus Edulis Foot Protein‐Based Hydrogel Adhesive with Osteo‐Vascular‐Immune Coupling Effects for Osteoporotic Bone‐Implant Integration

open access: yesAdvanced Materials, EarlyView.
Inspired by mussel proteins, YDC‐Gel‐Zn is a smart bone glue designed for osteoporotic implants. It adheres strongly to both metal implants and bone for initial fixation. In osteoporosis's inflammatory environment, it sequentially releases zinc ions and therapeutic peptides: the zinc modulates immune cells to reduce inflammation, while the peptides ...

Engineering Aging: Approaches to Model and Deconstruct Biological Complexity

open access: yesAdvanced Materials, EarlyView.
The macro‐experiences of aging are the result of an accumulation of micro‐changes that occur over time. Abstract The disparity between the global increase in life expectancy and the steady decline in health outcomes with age has been a major driver for developing new ways to research aging.

Unpredictable Root Canal Morphology: Expect the Unexpected

open access: yesAdvances in Human Biology, 2015
Background: A maxillary first molar with more than four canals is an interesting example of anatomic variations, especially when two of these canals are detected, with separate apical foramen in the distal root.
