Then, this macroscopic composite is cold drawn down to a diameter of 1mm with an intermediate annealing treatment (2h at 600°C) performed at 80% of reduction to recover some ductility.
At the final stage, the volume fraction of Mg in the composite is about 24% leading to a density of 6.3 (e.g. a reduction of about 20% comparing to steel).
Optical microscopy observations (data not shown here) did not reveal any significant change of the microstructure comparing to the original as-drawn material (i.e. no globulization of the filament was observed).
One should note however that the measured reduction of area was 22%, indicating that the composite exhibits a significant level of ductility.
After annealing the composite has obviously softened and the elongation at fracture has increased up to 12% (with a reduction area of 27%).

In order to check the permiability of mediator ABTS in the SAM layer, reduction currents of ABTS were measured in 2 mM ABTS solution with various SAM gold electrodes.
The reduction current around 600 mV in the O2 saturated solution was generated from the reaction between CotA and O2.
The reduction current at the CotA/1-butanethiol SAM gold electrode was higher than that at the bare electrode.

The XRD patterns of the rGO/Fe3O4 nanocomposite showed consistency with COD data number 3000327.
Analysis of the XRD data shows that the rGO sample displays amorphous characteristics with structural peaks identified at 2θ angles of 24.06°, 43.20°, and 77.78°, consistent with existing research [25].
The identification of these Bragg angles and planes was accomplished through refinement analysis using the Rietica software, referencing model data 3000327 from the COD [29].
The Rietveld refinement technique was employed to examine XRD data of rGO/Fe3O4 nanocomposites, specifically focusing on changes in rGO composition.
Using the Tauc equation shown in Eq. 3, researchers can calculate the bandgap energy value of the rGO/Fe3O4 nanocomposite by analyzing data obtained from UV-Vis characterization.

An ideal wind shield is required to create the greatest wind reduction over the longest shelter distance[7].
Both wind reduction and effective shelter distance are related to porosity.
Hence there should be a shield porosity that provides the optimal shelter effect by balancing the reduction in wind speed (pressure) with the effects on the shelter distance caused by the changes in turbulence and other factors.
The testing results revealed that the effects of the porous shape are negligible, because the discrepancies between the data for round and square shapes are irrelevant.

Mode 98BII computer electrochemical analysis system (Tianjin Branch of chemical electronic high-tech Co., Ltd.) was used to determine the CV data.
A pair of peak of oxidation-reduction (0.367 V/0.194 V) appears in the course of the initial deposition.
But the corresponding reduction peak is not clear.
Here the first pair of oxidation-reduction peak corresponds to the single-electron redox process and the followed pair of oxidation-reduction peak is attributed to a further oxidation process of one-electron.
There is no oxidation-reduction peak in the negative potential, but a pair of redox peaks appears in the positive potential area.

The routers can not only collect, process, and analyze data such as temperature, humidity, light, infrared, ultrasonic, audio, image data and so on, but also fuse and transfer data.
For the sensors using TWI interface, they are in sleep mode when the data acquisition is not need, and turn to normal working mode only when the data request arrives.
Each device transport image data to the parent node, namely the next hop router.
The adjacent frame differencing algorithm can reduce data redundancy and make the image transmission more efficient, controlling the amount of image data efficiently.
Firstly, the energy-saving of data acquisition module is evaluated separately.
