Usage of fiber Bragg grating sensors in low earth orbit environment

It is widely known that materials exposed to the severe low earth orbit (LEO) environment undergo degradations. For the evaluation of fiber Bragg grating (FBG) sensors in the LEO environment, the reflective spectrum change and the Bragg wavelength shift of FBG sensor were measured during aging cycles simulating the LEO environment. The LEO...

Shape-controlled tio₂ nanomaterials-based hybrid solid-state electrolytes for solar energy conversion with a mesoporous carbon electrocatalyst

One-dimensional (1D) titanium dioxide (TiO₂₎ is prepared by hydrothermal method and incorporated as nanofiller into a hybrid polymer matrix of polyethylene glycol (PEG) and employed as a solid-electrolyte in dye-sensitized solar cells (DSSCs). Mesoporous carbon electrocatalyst with a high surface area is obtained by the...

Association between thyroid function and heart rate monitored by wearable devices in patients with hypothyroidism

Background: Heart rate (HR) monitored by a wearable device (WD) has demonstrated its clinical feasibility for thyrotoxicosis subjects. However, the association of HR monitored by wearables with hypothyroidism has not been examined. We assessed the association between serum thyroid hormone concentration and three WD-HR parameters in...
