3D Fe3SnC/C hybrid nanofibers are proposed as a novel high-performance microwave absorber. At only 20 wt% filler loading, the optimal reflection loss reaches -119.2 dB at 17.1 GHz and the effective absorption bandwidth is 7.4 GHz with a thickness of 2.3 mm, outperforming most of the reported absorbers.

Digital orthodontics has been integrated into NasoAlveolar Molding (NAM) therapy to overcome challenges in the conventional NAM method. This study introduced an individualized Digital NAM (iDNAM) and evaluated the changes in the alveolar ridges and nasolabial morphology after iDNAM treatment. Prospective data were collected from 15 infants with complete unilateral cleft lip and palate who underwent iDNAM therapy.

Efficient cryopreservation of stem cells is crucial to fabricating off-the-shelf cell products for tissue engineering and regeneration medicine. However, it remains challenging due to utilization of toxic cryoprotectants for reducing ice-related cryodamages to stem cells during freeze-thaw cycle, stringent post-thaw washing process, and further integration of stem cells with scaffolds to form tissue engineering constructs for downstream applications. Herein, a novel cryopreservation platform of stem cells based on an antifreezing polyvinylpyrrolidone/gellan gum/gelatin (PGG) scaffold together is reported with an L-proline assisted cell pre-dehydration strategy.

Background: Surgery is the preferred treatment for primary hyperparathyroidism. Minimally invasive parathyroidectomy is only feasible with accurate preoperative localisation. Virtual 3D anatomical models can be constructed from patient-specific CT scans using segmentation software.

Oxygen vacancies in Ruddlesden-Popper (RP) perovskites (PV) [AO][ABO] play a pivotal role in engineering functional properties and thus understanding the relationship between oxygen-vacancy distribution and physical properties can open up new strategies for fine manipulation of structure-driven functionalities. However, the structural origin of preferential distribution for oxygen vacancies in RP structures is not well understood, notably in the single-layer ( = 1) RP-structure. Herein, the = 1 RP phase SrNdZnO was rationally designed and structurally characterized by combining three-dimensional (3D) electron diffraction and neutron powder diffraction.

Fast-charging lithium-ion batteries (LIBs) are the key to solving the range anxiety of electric vehicles. However, the lack of separators with high Li transportation rates has become a major bottleneck, restricting their development. In this work, the electrochemical performance of traditional polyethylene separators was enhanced by coating AlO nanoparticles with a novel green binder.
