AI Article Synopsis
- A Ta(3)N(5) nanorod photoelectrode was created using through-mask anodization and nitridation techniques for efficient water splitting.
- The photoanodes demonstrated a significant photocurrent density of 3.8 mA cm(-2) at a voltage of 1.23 V, indicating strong performance under simulated sunlight conditions.
- The incident photon-to-current conversion efficiency reached 41.3% at 440 nm, marking it as one of the top-performing photoanodes documented to date.
Article Abstract
A vertically aligned Ta(3)N(5) nanorod photoelectrode is fabricated by through-mask anodization and nitridation for water splitting. The Ta(3)N(5) nanorods, working as photoanodes of a photoelectrochemical cell, yield a high photocurrent density of 3.8 mA cm(-2) at 1.23 V versus a reversible hydrogen electrode under AM 1.5G simulated sunlight and an incident photon-to-current conversion efficiency of 41.3% at 440 nm, one of the highest activities reported for photoanodes so far.

When rendering the visual scene for near-eye head-mounted displays, accurate knowledge of the geometry of the displays, scene objects, and eyes is required for the correct generation of the binocular images. Despite possible design and calibration efforts, these quantities are subject to positional and measurement errors, resulting in some misalignment of the images projected to each eye. Previous research investigated the effects in virtual reality (VR) setups that triggered such symptoms as eye strain and nausea.

Timber-concrete composites are established structural elements to combine the advantageous properties of both materials by connecting them. In this work, an innovative flexible adhesive connection in different configurations is investigated. Load-bearing capacity, stiffness, and the failure modes were first experimentally investigated by performing push-out tests.

Objective: To identify the risk factors for proximal junctional failure (PJF) after adult spinal deformity (ASD) surgery despite ideal sagittal correction according to age-adjusted alignment target.
Methods: The study included patients who underwent low thoracic to pelvic fusion for ASD and obtained ideal correction according to age-adjusted pelvic incidence minus lumbar lordosis. PJF was defined either radiographically as a proximal junctional angle (PJA) of >28° plus a difference in PJA of >22° or clinically as revision surgery for proximal junctional complications.

Article Synopsis
- The study analyzed preoperative data from adult spinal deformity patients to establish a threshold for T1 slope (T1S) from cervical radiographs that indicates thoracolumbar malalignment.
- Researchers found a specific cutoff of 30 degrees for high T1S, with 50% of the patients falling above this threshold.
- Notably, higher T1S was linked with greater thoracic kyphosis, sagittal vertical axis, T1-pelvic angle, and pelvic tilt, suggesting that this measurement could serve as a useful parameter in cervical evaluations.

Background: Previous research on spinal alignment and postoperative outcomes after cervical and upper thoracic fixation has suggested that clinical and patient-reported outcomes are improved when certain anatomical parameters are maintained. These parameters include the cervical sagittal vertical axis (cSVA), C2 and T1 slopes, and cervical lordosis (CL). For patients with primary and metastatic tumors involving the subaxial cervical and/or upper thoracic spine, there is minimal guidance on how to apply these parameters.
