Porous tantalum rods for treating osteonecrosis of the femoral head

open access: yesGenetics and Molecular Research, 2014
This study evaluated the outcomes of using porous tantalum rods for the treatment of osteonecrosis of the femoral head (ONFH). We performed core decompression and inserted porous tantalum implants in 149 patients (168 consecutive hips) with ONFH. Hips had large (65), medium (64), or small (39) lesions; 63 lesions were lateral, 68 were central, and 35 ...

Dynamic‐FLPs Enabled by Orbital Hybridization Tuning: Boosting 100% CO Selectivity for Dilute CO2‐to‐CO Conversion

open access: yesCarbon Energy, EarlyView.
This study, for the first time, constructs photostructured dynamic frustrated Lewis pairs (DFLPs) via a p‐p orbital hybridization regulation strategy, achieving the 100% reduction of low‐concentration CO₂ to CO and breaking the stability‐activity trade‐off.

Meta-analysis of individual registry results enhances international registry collaboration

open access: yesActa Orthopaedica, 2018
Background and purpose — Although common in medical research, meta-analysis has not been widely adopted in registry collaborations. A meta-analytic approach in which each registry conducts a standardized analysis on its own data followed by a meta ...

Coupled Photocatalytic Hydrogen Production With Selective Biomass Valorization via Active Sites Construction and Electron Transport Channels Engineering

open access: yesCarbon Energy, EarlyView.
A ternary CdS/1T‐WS2/CNTs heterojunction is in‐situ constructed via hydrothermal method, which is used for photocatalytic biomass reforming (biomass‐derived alcohols, lignin). It exhibits outstanding performance: H2 production rate of 26.17 mmol/g/h for benzyl alcohol (BA), benzaldehyde (BD) generation rate of 8.29 mmol/g/h, 90.06% BD selectivity, 100%

A new mode of clinical failure of porous tantalum rod

open access: yesIndian Journal of Orthopaedics, 2010
The area of osteonecrosis of the head of femur affected by the disease process varies from a small localized lesion to a global lesion. Without specific treatment 80% of the clinically diagnosed cases will progress, and most will eventually require arthroplasty. Therefore the goal is to diagnose and treat the condition in the earliest stage.

Interplanar Potential Difference‐Mediated Efficient Charge Separation in SrLi2Ti6O14 Towards Optimized Photocatalytic Hydrogen Evolution

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The periodic quantum well formed by alternative stacking of SrO and LTO layers facilitates efficient photoinduced charge separation and thus significantly improves its photocatalytic hydrogen production performance. SrLi2Ti6O14 porous microspheres (SLTO PMSs) and SrLi2Ti6O14/TiO2 hollow sphere heterojunctions (SLTO/TiO2 HSs) are fabricated via ...
