Insights on Advances in 3D Bioprinting for Peripheral Nerve Regeneration

open access: yesAdvanced Therapeutics, EarlyView.
Peripheral nerve injury is a common condition due to trauma that significantly impacts the life of the affected individual. This review explores the anatomy, classification, and pathophysiology of peripheral nerve injuries. It also discusses various types of nerve conduits and presents a detailed review of 3D bioprinted nerve conduits used in both in ...

Aggregation in carbon dots

open access: yesAggregate, Volume 3, Issue 6, December 2022., 2022
Carbon dots (CDs) has excellent photoluminescence properties. Aggregation plays an important role in both the formation of CDs and their fluorescence, yet is seldom studied in detail. This review aims to fill this knowledge gap. We first discuss how aggregation leads to the formation of different types of CDs, and the impact on morphology, luminescence,

Unveiling Structural Heterogeneity and Evolutionary Adaptations of Heteromultimeric Bacterioferritin Nanocages

open access: yesAdvanced Science, EarlyView.
This study explores the structural heterogeneity and evolutionary adaptations of heteromultimeric bacterioferritins. Hetero‐Bfrs, evolved from either a homo‐Bfr or Ftn by gene duplications, differ from homo‐Bfrs substantially in the mechanisms underpinning iron oxidation and reduction despite high similarity in overall structure.

Collisions of red giants in galactic nuclei

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT In stellar-dense environments, stars can collide with each other. For collisions close to a supermassive black hole (SMBH), the collisional kinetic energy can be so large that the colliding stars can be destroyed, potentially releasing an amount of energy comparable to that of a supernova.

Lightweight 3D Hierarchical Metamaterial Microlattices

open access: yesAdvanced Science, EarlyView.
In this work, hierarchical lightweight 3D auxetic metamaterials based on cubic crystal lattice truss geometries are proposed. Microscale prototypes are fabricated using two‐photon lithography additive manufacturing and tested in situ. These hierarchical metamaterials are shown to exhibit a wide range of negative Poisson's ratios including giant ...

Two Steps Li Ion Storage Mechanism in Ruddlesden–Popper Li2La2Ti3O10

open access: yesAdvanced Science, EarlyView.
This study demonstrates the performance of Ruddlesden‐Popper Li₂La₂Ti₃O₁₀ as an anode material for lithium‐ion batteries, achieving 170 mAh·g⁻¹ capacity with two voltage plateaus from lithium ions stored at different sites. Unique unit cell changes during lithiation ensure high structural stability, leading to 88% capacity retention after 1000 cycles ...
