Conversion of Renewable Lignocellulosic Biomass‐Derived Nanocellulose into Graphene via Pyrolysis and High Shear‐Mediated Exfoliation

Small Structures, EarlyView.
This study uses nanocellulose crystals (NCCs) as the precursor for graphene production. The NCCs are pyrolyzed at 500–800 °C and then converted to graphene in the vortex fluidic device using only water as the solvent. The graphene shows a relatively high quality and TEM confirming <6 layers.

Research on a Drone‐Based Vacant Parking Detection System

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
It can be difficult to know which spaces are available in parking lots and bicycle parking areas, so knowing the availability status is necessary for efficient parking. Therefore, in this study, we developed the drone that can display the availability status. Availability is determined by whether it can read a QR code attached to the ground. To conduct

Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

Monitoring wildlife using long‐endurance solar‐electric UAVs

Wildlife Biology, EarlyView.
This report discusses the effectiveness of using small solar‐electric UAV (uncrewed aerial vehicles) for aerial wildlife monitoring. We review four years of aerial wildlife monitoring missions using a 5.5‐m wingspan, solar‐electric UAV that was equipped with a gimballed IR/RGB camera.

Highly‐Conductive Mixed PEO/PAN‐Based Membranes for Solid State Li‐Ion Batteries via Electro‐Spinning and Hot‐Press Synthesis Routes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Powder diffraction pattern of hot‐pressed polythylene oxide/ polyacrylonitrile polymerelectrolyte composites. Polyethylene oxide (PEO)‐based solid polymer electrolytes (SPEs) have been extensively studied for all solid‐state batteries (ASSBs) but still suffer from low thermal stability and ionic conductivity.
