Summary: Researchers designed a framework for triboelectrification (TE) between metal and single-crystal dielectrics using experiments and first-principles calculations. The experimental results showed a proportional relationship between charge density and interface barrier, supporting the proposed backflow-stuck charge model. Validation of the model was done by comparing theoretical predictions with extracted barriers from temperature-dependent triboelectrification.

Summary: This study elucidates the role of surface states on diamond materials for charge separation and emission under deep UV to visible light excitation. Four different spectroscopy methods were applied to diamond materials with different surface termination, doping, and crystallinity. Surface states were found to dominate sub-bandgap charge transfer, but the surface charge separation was drastically reduced in boron-doped diamond due to a high density of bulk defects. In a gaseous atmosphere, the oxidized diamond surface maintains a negative electron affinity, allowing charge emission. In an aqueous electrolyte, a photocurrent for illumination down to 3.5 eV was observed for boron-doped nanostructured diamond, independent of the surface termination. This study opens new perspectives on photo-induced interfacial charge transfer processes from metal-free semiconductors such as diamonds.

Summary: This article proposes a new design strategy to increase the current of the water droplet nanogenerator by simultaneously scavenging the mechanical energy of the liquid-solid contact and the deformation energy. A droplet-based triboelectric-piezoelectric hybridized nanogenerator (TPiHNG) with a cantilever beam structure is fabricated under this strategy, achieving more efficient scavenging of water droplet energy.

Summary: The TiO2/BiOI heterojunctions prepared by facile hydrothermal synthesis exhibit enhanced photocatalytic activity, with significantly improved separation efficiency of photogenerated carriers and introduction of more oxygen vacancies. The photocatalytic activity of the TiO2/BiOI heterojunctions is almost 4 times higher than that of neat BiOI under simulated sunlight, suggesting a step-scheme mechanism for the separation of photoactivated carriers.

Summary: In this study, a new strategy was developed to achieve maximum charge density in a high-output triboelectric nanogenerator (TENG). By designing a cationic material structure of SiO2 and MoS2 coated on a Ni-mesh, the new TENG generated significantly higher output power and superior charge density compared to Ni-mesh-based TENGs. The high charge density was attributed to the low work function of MoS2, upward bending of the energy band at the MoS2-SiO2 interface, and the high charge capacity of SiO2. The TENG demonstrated an average output power of 14.75 W m(-2) based on the gear-cam mode.

Summary: This study demonstrates the successful fabrication of well-defined BiVO4 square nanocrystals with precisely controllable facet proportion, and reveals the spatial charge separation process within these nanocrystals, showing that the charge separation efficiency depends on the facet proportion. The matching degree of charge collection length and crystal configuration is considered to be the major factor determining charge separation efficiency of BiVO4 nanocrystals.

Summary: In this study, the authors demonstrate the morphology tailoring of cuprous oxide (Cu2O) crystals from cubic to octahedral and truncated octahedral shapes. They use Kelvin probe force microscopy to observe the photogenerated charge separation on the exposed anisotropic facets and find that facet junction greatly improves charge separation efficiency. The authors further investigate the facet-dependent photocorrosion of Cu2O in a photoelectrochemical process and correlate it with the self-reduction from photo-induced electrons. These findings highlight the crucial role of anisotropic facet engineering in regulating photogenerated charge behaviors and surface reactions in photocatalytic energy conversion.

Summary: In this paper, we investigate the secure computation offloading in the Marine Internet of Things (M-IoT) with the assistance of unmanned surface vehicles (USVs) subject to the eavesdropping attack. We optimize the USVs' positions, the duration of data uploading, the workload offloaded by the high altitude platform (HAP), the HAP's transmission power, and the USVs' jamming signal power to minimize the system-wise energy consumption for completing the total workloads under the latency constraint. Our proposed algorithms, PAS-Algorithm and CASE-Algorithm, effectively optimize the variables and provide suboptimal solutions to the joint optimization problem, validating their accuracy and performance compared with benchmark algorithms.

Summary: Iron is crucial for biological processes, but excessive iron can be toxic. In patients with recurrent pregnancy loss (RPL), low serum iron and iron deposition in the decidua were simultaneously observed. Mice fed with a low-iron diet also showed iron deposition in the decidua and adverse pregnancy outcomes. Decreased expression of ferroportin, an iron exporter, in decidual stromal cells (DSCs) may explain the local iron deposition. Iron supplementation reduced iron deposition and improved pregnancy outcomes. Excessive iron led to ferroptosis of DSCs, but supplementation of glutathione (GSH) and cystine reduced cell death. Ferroptosis inhibitors also attenuated DSC ferroptosis and reversed embryo loss, indicating a potential therapeutic target for RPL patients.

Summary: This study aimed to evaluate the association between blood cesium concentration and lung function alteration in COPD patients and explore the potential role of oxidative stress in this association. The study found a non-linear relationship between blood cesium concentration and lung function in COPD patients, with an increase in blood cesium associated with reductions in FVC and predicted FEV1%. Smoking status exacerbated the pulmonary function reduction caused by cesium. Blood cesium was inversely associated with pulmonary function parameters, while positively related to serum 8-iso-PGF2 alpha. Oxidative stress may play an important role in mediating the effect of cesium exposure on pulmonary function reduction in COPD patients.

Summary: Inflammation of fetal membranes during parturition is accompanied by increased synthesis of prostaglandin E2 (PGE2), despite the presence of anti-inflammatory glucocorticoids. This study investigates the role of 15(S)-hydroxyeicosatetraenoic acid (15(S)-HETE) in promoting PGE2 synthesis in amnion fibroblasts. It is found that cortisol and 15(S)-HETE levels increase in parallel in the amnion during parturition. Cortisol induces the expression of ALOX15/15B and production of 15(S)-HETE in amnion fibroblasts through p300-mediated histone acetylation and interaction with transcription factors CREB and STAT3. These findings suggest that cortisol regeneration in fetal membranes paradoxically enhances PGE2 synthesis in the inflammatory responses of fetal membranes.

Summary: This study aimed to investigate the relationship between cadmium exposure and mortality among postmenopausal females. The results showed that higher concentrations of cadmium in blood and urine were significantly associated with an increase in all-cause mortality for postmenopausal females. There was a linear positive correlation between urine cadmium concentrations and cancer mortality, while there was no correlation between blood cadmium and cancer death. Reducing cadmium exposure can promote the health and lifespan of postmenopausal women.
