Methods: This retrospective study reviewed 25 patients with unilateral closed comminuted patellar fractures who underwent open reduction and internal fixation using either non-absorbable sutures tied with a Nice knot (NK group, n = 12) or the traditional tension band technique (TB group, n = 13).

Recent advances and perspectives of electrolyte additives for enhanced anode reversibility in aqueous zinc-ion batteries.

Although lithium-ion batteries have achieved widespread commercial success, they are not suitable for large-scale energy applications due to limited lithium resources and relatively high cost. In this context, aqueous zinc-ion batteries (AZIBs) have emerged as promising alternatives, offering advantages such as cost-effectiveness, superior safety and a simplified manufacturing process. Nevertheless, AZIBs currently face a series of critical challenges, including uncontrolled dendrite growth, low zinc utilization efficiency and notorious side reactions.

Perfect anomalous refraction metasurfaces empowered half-space optical beam scanning.

Metasurface-based optical beam scanning devices are gaining attention in optics and photonics for their potential to revolutionize light detection and ranging systems. However, achieving anomalous refraction with perfect efficiency (>99%) remains challenging, limiting the efficiency and field of view (FOV) of metasurface-based optical beam scanning devices. Here, we introduce a paradigm for achieving perfect anomalous refraction by augmenting longitudinal degrees of freedom arousing a multiple scattering process to optimize symmetry breaking.

Factors influencing residual air saturation during consecutive imbibition processes in an air-water two-phase fine sandy medium - A laboratory-scale experimental study.

The residual air saturation plays a crucial role in modeling hydrological processes of groundwater and the migration and distribution of contaminants in subsurface environments. However, the influence of factors such as media properties, displacement history, and hydrodynamic conditions on the residual air saturation is not consistent across different displacement scenarios. We conducted consecutive drainage-imbibition cycles in sand-packed columns under hydraulic conditions resembling natural subsurface environments, to investigate the impact of wetting flow rate, initial fluid state, and number of imbibition rounds (NIR) on residual air saturation.

Insight into the Enforced Stability of the Solid Electrolyte Interphase on the Graphite Anode by Prelithiation.

Prelithiation in a graphite anode is widely considered as an effective strategy to compensate for the lithium loss due to the formation of the solid electrolyte interphase (SEI), thus improving the cycle life of lithium-ion batteries (LIBs). However, less attention has been paid to the difference of the SEI established by prelithiation from that resulting from the charging process. To address this issue, a prelithiated graphite anode is prepared by thermal contact and its performances are investigated by electrochemical measurements and spectral characterizations.

A multi-orientation system for characterizing microstructure changes and mechanical responses of fine-grained gassy sediments associated with gas hydrates.

Fine-grained marine sediments containing veiny and nodular gas hydrates will evolve into fine-grained gassy sediments after hydrate dissociation due to climate-driven ocean warming. The mechanical properties of the fine-grained gassy sediments are basically acquired by ocean engineering design. However, they have not been fully understood, largely due to the lack of microstructure visualization.

Enhanced Circular Dichroism for Achiral Sensing Based on a DNA-Origami-Empowered Anapole Metasurface.

Circular dichroism (CD) spectroscopy has been extensively utilized for detecting and distinguishing the chirality of diverse substances and structures.
