Autonomous Implants

open access: yesAdvanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Formation of Q‐Carbon Nanoballs and Nanodiamonds by Pulsed Laser Annealing of Patterned Polymer Structures

open access: yesAdvanced Materials Interfaces, EarlyView.
2D and 3D patterned structures of Q‐carbon nanoballs and nanodiamonds have been created by laser writing of polymers, carbonization, and pulsed laser annealing. Polymeric structures are prepared by using a direct‐laser‐writing (DLW) process involving two‐photon polymerization (2PP). Patterned nanodiamond and Q‐carbon growth over large areas is obtained

Supersymmetric AdS$$_2\times \Sigma _2$$ 2×Σ2 solutions from tri-sasakian truncation

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
A class of $$\mathrm{AdS}_2\times \Sigma _2$$ AdS2×Σ2 , with $$\Sigma _2$$ Σ2 being a two-sphere or a hyperbolic space, solutions within four-dimensional $$N=4$$ N=4 gauged supergravity coupled to three-vector multiplets with dyonic gauging is identified.

Jigsaw Pattern Infills Inspired by Toughening Mechanisms of Diabolical Ironclad Beetle for 3D Printing Technologies

open access: yesAdvanced Materials Technologies, EarlyView.
A biomimetic Jigsaw pattern infill for 3D printer has been developed. Its mechanical features with continuous carbon fiber reinforcement (CCFR) are investigated through the Design of Experiments. The Jigsaw infill minimizes mechanical strength losses caused by variability in infill density, flow rate, or carbon fiber string amount, outperforming ...

Applications of QSPR and Machine Learning in Molecular Photonics

open access: yesAdvanced Optical Materials, EarlyView.
Quantitative structureproperty relationships (QSPR) and machine learning (ML) are transforming photochemistry by enabling pre‐synthetic screening of photoactive molecules. This review outlines advances in data‐driven discovery of optical materials and functional dyes, identifies effective descriptors and models for photophysical processes, and provides
