Introduction This study aimed to evaluate the effectiveness of mHealth management with an implantable glucose sensor and a mobile application among patients with type 2 diabetes mellitus (T2DM) in China. Methods A randomised controlled trial was carried out to compare the effectiveness of usual health management to mHealth management based on a model that consisted of the network platform, an implantable glucose sensor and a mobile app featuring guidance from general practitioners (GPs) over a four-week period. Patients ( N=68) with T2DM were randomly divided into an intervention group and a control group. Before the intervention, there was no difference in body mass index (BMI), fasting blood glucose (FBG), postprandial two-hour blood glucose (2hPG) and glycosylated haemoglobin (HbA1c) between the intervention group and the control group ( p>0.05). Patients in the control group received their usual health management, while patients in the intervention group received mHealth management. Results After health management, the mean BMI, FBG, 2hPG and HbA1c of the intervention group patients were all lower than those of the control group patients ( p < 0.05), and the quality of life and self-management of the intervention group patients had significantly improved. Discussion mHealth management effectively showed significant reductions in BMI, FBG, 2hPG and HbA1c and improved quality of life and self-management among patients, which may be related to real-time feedback from an implantable glucose sensor and guidance from GPs through a mobile app. mHealth management is a very promising way to promote the health management of T2DM in China, and this study provides a point of reference for mHealth management abroad.

Though great achievements have been realized in perovskite solar cells (PSCs), there are still some thorny challenges that exist such as: 1) How to minimize the interfacial nonradiative recombination losses; 2) How to balance the power conversion efficiency (PCE) and environmental friendliness of the PSCs. Here, effective top‐contacts‐interface engineering is developed via using a new multi‐active site Lewis base molecule named emtricitabine (FTC). Both, experimental and theoretical results confirm that a strong chemical interaction exists between FTC and Pb2+. After FTC treatment, the perovskite thin film has the lower density of defect than the control film, meanwhile, the interfacial hole extraction becomes better due to the more matched energy level. Upon the FTC passivation, the PCE of the PSCs is improved from 20.83% to 22.24%. Simultaneously, the humidity stability of the PSCs is improved after the FTC modification. Last but not least, the unpackaged target film showed less lead leakage than the control film.

Recently, the development efforts focused on the computer simulation of garments, which depend on the material's physico-mechanical properties. It intends to achieve the best possible and realistic simulations of garments, which are available for pressure prediction. In this manner, 3D garment virtual technology improvements allow the visualization of pressure areas with values where the fabric might be too tight against the body. Although the purposes of simulation graphics were acceptable, the accuracy for apparel shaping is not enough to meet the needs of Virtual Prototyping and CAD utilization especially while the fabric properties system design was inadequate. Moreover, the existing pressure simulation is intended to simply predict the pressure index or how the textile deformation extend, which are deficient in real human's perception. In this research, the 3D shapes belonging to typical female bodies and dresses made of different fabrics were obtained by 3D body scanners (ScanWorX and TELMAT). Through reconstruction for the 3D torso shapes, the volumetric eases between body and dress were calculated by means of a software Rhinoceros. A new approach for the selection of textile properties based on the Kawabata Evaluation System (KES) was proposed to investigate its relations with dress shaping and pressure comfort. Finally, fabric properties tested by the KES-F system were compared with volumetric eases, objective pressure indexes and subjective comfort scores to reveal the relations how the fabric properties have impacts on dress outside shaping and inside pressure comfort of a female body. In this manner, the human-friendly CAD instead of mechanical approach existing before has been presented as a new approach to promote the construction of a realistic system for the 3D simulation optimization.

Perovskite solar cells (PSCs) have achieved huge success in power conversion efficiency (PCE) and stability. However, further improving the PCE of PSCs and stability is still a big challenge. Here, we attempt to improve the PCE and stability of PSCs using a functional additive named 3-mercaptopropyltriethoxysilane (SiSH) in the perovskite antisolvent. It is revealed that SiSH can release the stress in the film, reduce the defects, and inhibit lithium-ion migration and lead leakage. As a result, the target device achieves an efficiency enhancement from 20.80 to 22.42% as compared to the control device. Meanwhile, device stability is ameliorated after SiSH modification. Furthermore, new adsorbents are used to treat the leaked lead to make it comply with safe drinking water standards. This work provides an idea for developing multifunctional antisolvent additives and adsorbents for high PCE, long stability, and environment-friendly Pb-based PSCs.
