Atomic Gap-State Engineering of MoS for Alkaline Water and Seawater Splitting.

Transition-metal dichalcogenides (TMDs), such as molybdenum disulfide (MoS), have emerged as a generation of nonprecious catalysts for the hydrogen evolution reaction (HER), largely due to their theoretical hydrogen adsorption energy close to that of platinum. However, efforts to activate the basal planes of TMDs have primarily centered around strategies such as introducing numerous atomic vacancies, creating vacancy-heteroatom complexes, or applying significant strain, especially for acidic media. These approaches, while potentially effective, present substantial challenges in practical large-scale deployment.

Efficiency and Safety of Repeated Vertebroplasty for Adjacent Segment Fractures.

To review the outcomes of patients who underwent repeated vertebroplasty (VP) surgery for adjacent segment fractures (ASF), defined as new osteoporotic vertebral fractures occurring at levels immediately above or below a previously treated vertebra. From 1 January 2018, to 31 December 2020, forty-one patients who developed ASF following initial VP and underwent repeated VP were enrolled in our study. Radiographic measurements included single and two-segment kyphotic angles (SKA and TKA), and anterior and mid-vertebral body height (AVH and MVH).

Review of Short-Wavelength Infrared Flip-Chip Bump Bonding Process Technology.

Short-wave infrared (SWIR) imaging has a wide range of applications in civil and military fields. Over the past two decades, significant efforts have been devoted to developing high-resolution, high-sensitivity, and cost-effective SWIR sensors covering the spectral range from 0.9 μm to 3 μm.

Long-Gauge Fiber Optic Sensors: Strain Measurement Comparison for Reinforced Concrete Columns.

Long-gauge fiber optic sensors have proven to be valuable tools for structural health monitoring, especially in reinforced concrete (RC) beam structures. While their application in this area has been well-documented, their use in RC columns remains relatively unexplored. This suggests a promising avenue for further research and development.

LuAlO:Ce Fluorescent Ceramic with Deep Traps: Thermoluminescence and Photostimulable Luminescence Properties.

Electron-trapping materials have attracted a lot of attention in the field of optical data storage. However, the lack of suitable trap levels has hindered its development and application in the field of optical data storage. Herein, LuAlO:Ce fluorescent ceramics were developed as the optical storage medium, and high-temperature vacuum sintering induced the formation of deep traps (1.
