The photovoltaic performance of inverted perovskite solar cells (PSCs) relies on effectively managing the interface between the hole extraction layer and the light-absorbing perovskite layer. In this study, we have synthesised (4-(3,6-bis(methylthio)-9H-carbazol-9-yl)butyl)phosphonic acid (MeS-4PACz), which forms a self-assembled monolayer on the fluorine-doped tin oxide (FTO) electrode. The molecule's methylthio substituents generate a favourable interfacial dipole moment and interact with the perovskite layer.

MnO nanowires coated with conjugated microporous polymers (CMP) are applied as triboelectric energy harvesting materials. The tribopositive performance of the CMP shells is enhanced with the assistance of MnO nanowires (MnO NW), likely due to cationic charge transfer from the tribopositive CMP layers to the surface Mn and Mn species of MnO NW. This is supported by model studies.

The lithium-mediated nitrogen reduction reaction (Li-NRR) is a promising green alternative to the Haber-Bosch process for ammonia synthesis. The solid electrolyte interphase (SEI) is crucial for high efficiency and stability, as it regulates reactant diffusion and suppresses side reactions. The SEI properties are greatly influenced by the Li ion solvation structure, which is controllable through electrolyte engineering.

Musculoskeletal disorders occur frequently in industrial settings, and police officers in particular are at high risk of developing musculoskeletal disorders due to the nature of their work, but research on this is lacking. Therefore, the purpose of this study was to examine the prevalence and risk factors of musculoskeletal disorders according to the job functions of police officers. A survey was conducted, targeting active-duty police officers, and data were collected from 4268 respondents who answered all items on the questionnaire.

Article Synopsis
  • Approximately 600 million people are infected with Strongyloides stercoralis, which primarily affects humans but can also infect non-human primates, dogs, and cats, raising concerns about zoonotic transmission.
  • In a study conducted in Bangladesh, researchers collected and analyzed Strongyloides and hookworm samples, discovering a higher incidence of S. fuelleborni in humans than expected, and identifying two types of S. stercoralis without evidence of genetic isolation from other regions.
  • The findings suggest that S. fuelleborni may be a more significant human parasite in parts of Asia, and potential genetic exchange between S. stercoralis types could lead to important implications, such as drug resistance.

Tin-lead (Sn-Pb) perovskite solar cells (PSCs) hold considerable potential for achieving efficiencies near the Shockley-Queisser (S-Q) limit. Notably, the inverted structure stands as the preferred fabrication method for the most efficient Sn-Pb PSCs. In this regard, it is imperative to implement a strategic customization of the hole selective layer to facilitate carrier extraction and refine the quality of perovskite films, which requires effective hole selectivity and favorable interactions with Sn-Pb perovskites.

  • This study investigates how to distinguish between different lesions related to impacted mandibular third molars (IMTs) by comparing panoramic and cone-beam computed tomography images.
  • A retrospective analysis was performed on patients who had both IMT extractions and benign tumor or cyst surgeries between 2017 and 2021, focusing on the characteristics of dentigerous cysts, odontogenic keratocysts (OKCs), and ameloblastomas.
  • Findings revealed that lesion size varied significantly among types, with ameloblastomas being the largest, followed by OKCs and dentigerous cysts, and also indicated that younger patients tended to have larger OKCs and odontogenic tumors.

Background: For the surgical treatment of oral cancer, it is sometimes necessary to expand intraoral access within the oral cavity. The "swing approach" that involves lip splitting of the mandible and temporary mandibular osteotomy and the "visor approach" that does not split the lower lip and mandible are mainly used. This study analyzed postoperative outcomes such as complications, recurrence rate, and survival rate by these two approaches.

Radio frequency (RF) hyperthermia focuses on raising the target area temperature to a value exceeding 45°C. Collagen is stimulated when the temperature rises to 45°C at the dermal layer, resulting in skin tightening. However, most studies on RF hyperthermia have focused on tumor ablation or using electrodes to radiate an electromagnetic field, which is highly inefficient.

  • The study investigates the connection between the lateral femoral condylar ratio (LFCR) and lateral meniscus posterior root tears (LMPRTs) in patients with anterior cruciate ligament (ACL) injuries, particularly in noncontact cases.
  • It involves a comparison between two groups: one with confirmed LMPRTs and one without, analyzing demographic factors, LFCR, and posterior tibial slope (PTS).
  • Findings reveal that a higher LFCR significantly correlates with LMPRTs, with a specific cutoff point indicating an enlarged risk for these tears in ACL injury patients.
