Raman spectra of human skin obtained by laser excitation have been used to non-invasively detect blood glucose. In previous reports, however, thus were mainly derived from the epidermis and interstitial fluid as a result shallow penetration depth lasers in skin. The physiological process which glucose microvessels penetrates into introduces time delay, inevitably errors transcutaneous measurements We focused directly on superficial layer nailfold, acquired with multiple characteristic peaks...

Fluorotellurite microstructured fibers (MFs) based on TeO2-BaF2-Y2O3 glasses are fabricated by using a rod-in-tube method. Tapered fluorotellurite MFs with varied transition region lengths prepared employing an elongation machine. By tapered MF length of ∼3.3 cm as the nonlinear medium and 1560 nm femtosecond fiber laser pump source, broadband supercontinuum generation covering from 470 to 2770 is obtained. The effects also investigated. Our results show that promising media for generating...

Revealing low-dimensional material growth dynamics is critical for crystal engineering. However, in a practical high-temperature system, the process black box because of lack heat-resistant imaging tools. Here, we develop optical microscope and embed it chemical vapor deposition (CVD) system to investigate two-dimensional (2D) dynamics. This situ CVD can tolerate temperatures ≤900 °C with spatial resolution ∼1 μm. The monolayer MoS2 crystals was studied as model 2D growth. nucleation have...

Abstract The rational design of carbon‐supported transition metal single‐atom catalysts necessitates precise atomic positioning within the precursor. However, structural collapse during pyrolysis can occlude single atoms, posing significant challenges in controlling both their utilization and coordination environment. Herein, we present a surface atom adsorption‐flash heating (FH) strategy, which ensures that pre‐designed carbon nanofiber structure remains intact heating, preventing...

Ferromagnetic L10−MnGa thin films have been epitaxially grown on GaN, sapphire, and MgO substrates using molecular beam epitaxy. Using diffraction techniques, the epitaxial relationships are determined. It is found that crystalline orientation of differ due to influence substrate. By comparing magnetic anisotropy structural properties, a clear correlation could be established indicating in-plane out-of-plane directly determined by crystal film controlled via selection substrates. This result...

Erythropoietin (Epo) promotes functional recovery following spinal cord injury (SCI); however, the exact underlying mechanisms are yet to be determined. Although endogenous neural stem cells (NSCs) in adult a therapeutic target SCI models, effect of Epo on this NSC population remains unknown. The present study investigated effects NSCs both vitro and vivo. For vivo analyses, normal rats (Normal) contusion model (SCI) received either recombinant human or saline treatment for 7 days (5,000...

Precise monolayer epitaxy is important for two-dimensional (2D) semiconductors toward future electronics. Here, we report a new self-limited approach, liquid phase edge (LPEE), precise-monolayer of transition-metal dichalcogenides. In this method, the solution contacts 2D grains only at edges, which confines grain edges and then precise can be achieved. High-temperature in situ imaging progress directly supports edge-contact mechanism. Typical dichalcogenide monolayers (MX2, M = Mo, W, Re; X...
