“…With the continuous upgrading of electronic devices, their densification and integration trend will inevitably lead to the release of a large amount of heat during work, resulting in local high temperatures and even damaging electronic components [1]. According to research, under certain conditions, the reliability of electronic components will decrease by 5% when the temperature increases by 1 °C [2].…”

Thermal conductivity grease (TSG) is an important interface material for electronic devices’ heat dissipation. A continuous free-arc dispersion-spraying method of carbon nanotubes (CNTs) and nanocrystalline silicon carbide (SiC) for the preparation of TSG is reported. CNTs and SiC are dispersed and mixed by a free arc and are sprayed on the silicone oil surface (carried by the conveyor belt). Then, the silicon oil is separated from the conveyor belt, and the TSG composite (TSG-E) with highly dispersed CNTs@SiC is prepared. In this work, TSG-E has a CNTs@SiC network with CNTs as the frame and SiC as the node. Compared with untreated (TSG-N), grind (TSG-G), and ultrasonic (TSG-U) dispersion methods, TSG-E has better thermal conductivity (λ) and resistivity. CNTs@SiC network of the TSG-E series affects λ, the effect follows the thermal conductivity network theory and has a sudden change (greatly decreased) from TSG-E0.2 to TSG-E0.3. Besides, the sudden change of thermal stability for the TSG-E series is consistent with the change of λ.

“…Although the time required for the thermal cycles and the sample preparation was dramatically reduced by implementing both the plasmonic photothermal cycler [28,38] and the direct PCR in the RT-qPCR, the cost per PCR test can still be reduced by innovating the materials and manufacturing techniques. To reduce the cost per PCR close to LFAs, a film of low-cost photothermal material like carbon [39,40] can be manufactured with high throughput manufacturing techniques such as the roll-to-roll (R2R) printing method. [41,42] Therefore, to perform RT-qPCR in the POC device, the assay would be beneficial if it is achieved in a single device within tens of minutes by utilizing lysate without the RNA purification and the photothermal cycler with the inexpensive photothermal heating and cooling method.…”

The COVID‐19 outbreak has caused public and global health crises. However, the lack of on‐site fast, reliable, sensitive, and low‐cost reverse transcription polymerase chain reaction (RT‐PCR) testing limits early detection, timely isolation, and epidemic prevention and control. Here, the authors report a rapid mobile efficient diagnostics of infectious diseases via on‐chip ‐RT‐quantitative PCR (RT‐qPCR): MEDIC‐PCR. First, the authors use a roll‐to‐roll printing process to accomplish low‐cost carbon‐black‐based disposable PCR chips that enable rapid LED‐induced photothermal PCR cycles. The MEDIC‐PCR can perform RT (3 min), and PCR (9 min) steps. Further, the cohort of 89 COVID‐19 and 103 non‐COVID‐19 patients testing is completed by the MEDIC‐PCR to show excellent diagnostic accuracy of 97%, sensitivity of 94%, and specificity of 98%. This MEDIC‐PCR can contribute to the preventive global health in the face of a future pandemic.

To improve the problems of large interface thermal resistance and low heat dissipation efficiency in battery thermal management (BTM), this paper uses methyl silicone oil as the matrix, AIN, copper powder (CP), and carbon fiber (CF) as thermally conductive fillers, and acetone and stearic acid as particle surface modification components. A variety of binary thermal silicone greases (TSGs) with different compositions were prepared. Different instruments were used to test the material properties of TSGs, and a better TSG was selected to coat the interface between battery and phase change material (PCM) for battery charging and discharging experiments. Through the analysis of experimental data, it was found that among the TSGs made of three mixed fillers (AIN/CP, AIN/CF, CP/CF), the three TSGs had good thermal stability, and their thermal degradation temperature both exceeded 300 °C. As the ratio of thermally conductive filler was gradually changed from 5:1 to 1:5, the TSG containing CP/CF had higher thermal conductivity and lower volume resistivity, while the TSG containing AIN/CF had the least damage due to interface wear. The acidification treatment of thermally conductive filler can improve the adsorption and compatibility of thermally conductive particles and silicone oil, and reduce the oil separation rate of TSGs. The prepared expanded graphite (EG)/paraffin wax (PW) composite phase change material (CPCM) has a relatively large latent heat of phase change, which can effectively control the temperature of the battery, but coating TSG between the battery and the CPCM can further enhance the heat dissipation effect of the battery.
