Creating Tunable Micro-Optical Components via Photopolymerization 3D Printing Combined with Polymer-Dispersed Liquid Crystals.

Based on additive manufacturing via photopolymerization, this study combines polymer-dispersed liquid crystal (PDLC) technology with 3D printing technology to produce tunable micro-optical components with switchable diffraction or focusing characteristics. The diffraction grating and Fresnel zone plate are the research targets. Their structures are designed and simulated to achieve expected optical functions.

Torsion and ruptured ovarian cystadenocarcinoma with internal bleeding complicated with retroperitoneal hematoma after tumor transection: A case report.

Rationale: Ovarian tumor torsion is a critical gynecological emergency, predominantly affecting women of reproductive age, with benign teratomas being the most common culprits. In contrast, malignant ovarian tumors, such as mucinous cystadenocarcinoma, infrequently present with torsion due to their invasive and angiogenic characteristics. The occurrence of torsion in malignant tumors complicates diagnosis and management, particularly when associated with complications like congestion, infarction, and internal bleeding.

Hybrid spin coating and evaporation techniques for fabricating double-layer stacked dual-color perovskite LEDs.

This work reports on the preparation process of a double-layer perovskite active layer. The first active layer film, CsKPEAPbIBr, was fabricated using a spin-coating method, while the second active layer, MAPbBr, was deposited using MAPbBr single crystals as the evaporation source. Additionally, doping the PEDOT: PSS hole transport layer with ETA and EDA can enhance the uniformity of the perovskite film and reduce voids, improving charge transport efficiency.

Targeting IL-20 alleviates inflammatory mechanical allodynia and reduces epidural fibrosis in post-laminectomy syndrome rat model.

Background: Post-laminectomy syndrome (PLS) manifests as recurrent chronic back pain, with or without radiating leg pain, affecting 10-40% of patients following laminectomy. While surgical interventions can alleviate recurrent disc herniation or joint instability, medical management of PLS remains challenging due to unsatisfactory outcomes. Epidural fibrosis is a frequent cause of PLS, leading to nerve root tethering and dural sac compression.

A High-Sensitivity Fiber Optic Soil Moisture Sensor Based on D-Shaped Fiber and Tin Oxide Thin Film Coatings.

We present a high-sensitivity fiber optic soil moisture sensor based on side-polished multimode fibers and lossy mode resonance (LMR). The multimode fibers (MMFs), after side-polishing to form a D-shaped structure, are coated with a single-layer SnO thin film by electron beam evaporation with ion-assisted deposition technology. The LMR effect can be obtained when the refractive index of the thin film is positive and greater than its extinction coefficient and the real part of the external medium permittivity.
