Fine-Grained Reliability for V2V Communications around Suburban and Urban Intersections

open access: yes, 2017
Safe transportation is a key use-case of the 5G/LTE Rel.15+ communications, where an end-to-end reliability of 0.99999 is expected for a vehicle-to-vehicle (V2V) transmission distance of 100-200 m.

Driving Micro‐Objects Using Optical Force due to Fluorescence Emission From Molecules

open access: yesAdvanced Optical Materials, EarlyView.
Emission of fluorescence from a micro‐object in a specific direction is expected to generate an optical force driving the object in the opposite direction of the emission, like a rocket. To demonstrate this ‘photon‐driven micro‐rocket’, we prepared dye‐doped polymer micro‐object (PMO) one surface of which was covered with metallic film; the PMO ...

Surfing the Color Map with Carbazole‐Appended Cyclometalated N‐Heterocyclic Carbene Pt Complexes and Their Application in Green Organic Light‐Emitting Devices

open access: yesAdvanced Optical Materials, EarlyView.
Complexes [PtII(Cbz‐C^C*bzim/im)(L^L)], bearing carbazole‐appended cyclometalated NHCs, show bright phosphorescence, peaking from the blue to the yellowish–green spectral range depending on the carbene, L^L, and doping concentration. Non‐doped OLEDs using 1A or 3A (L^L = acac or P^O2) reach the best performances (Von: 2.99 V, 2.55 V; Lmax: 39208, 25837

Electric Field Inhomogeneity in Colloidal QD‐LEDs

open access: yesAdvanced Optical Materials, EarlyView.
Variations in the thickness of the quantum dot (QD) active layer in a quantum dot light emitting diode leads to variations in the local electric field strength. Thicker regions insulate the QDs from the applied electric field. Under normal operating conditions, this leads to lower electroluminescence.

Wireless Nano Irradiance Meter Based on Upconversion Luminescence Lifetime

open access: yesAdvanced Optical Materials, EarlyView.
A wireless nano irradiance meter is developed based on upconversion nanoparticles that enabled local readouts through their luminescence lifetime. This method allows for remote and precise light irradiance quantification in complex media, offering significant potential for light‐based technologies such as photodynamic therapy and nanothermometry ...

Evolution of aging depth gradient distribution in SBS-modified bitumen during the aging of field

open access: yesCase Studies in Construction Materials
This study investigated the distribution of aging depth gradients in styrene-butadiene-styrene modified bitumen (SBSMB) during natural aging. SBSMB was sourced from bitumen recycling tests and was stratified into upper, middle, and lower layers according
