Currently, in the domestic practice of retreading tires using vulcanization tanks, some tanks exhibit uneven temperature distributions leading to low retreading success rates. To address that, this paper simulated the temperature and velocity fields during the heating process of vulcanization tanks for waste tire retreading. The results indicated that a higher heating power reduces the time required for the vulcanizing agent to reach the vulcanization condition, but it also increases the difference in tire temperature in the tank, with a severely uneven distribution of the temperature field.

Article Synopsis
  • A study involving 2860 mother-child pairs examined how prenatal exposure to certain antibiotics, specifically Tetracycline and Ofloxacin, may influence the development of autism spectrum disorder (ASD) symptoms in children by analyzing urinary concentrations during pregnancy.
  • The research found that maternal exposure to Tetracycline throughout pregnancy significantly elevated the risk of ASD symptoms, particularly during the first and third trimesters in boys, while Ofloxacin exposure during the first trimester posed increased risk for girls.
  • No clear dose-dependent relationship was established, indicating that it was the presence of these antibiotics during specific pregnancy periods that correlated with heightened ASD symptoms rather than the amount of exposure.

Article Synopsis
  • Improvements in lithium-ion batteries (LIBs) lead to longer driving distances and faster charging for electric vehicles (EVs), but thicker electrodes can slow down ion diffusion and reduce stability.
  • A surprising discovery shows that creating tiny conical pores in electrodes enhances Li-ion transport, overcoming bottlenecks caused by dense surface layers.
  • Simulation studies back up experimental results, suggesting that these design changes can help produce more affordable and efficient EVs with greater range and quicker charging.

Electrochemical carbon dioxide reduction reaction (eCORR) to generate syngas is an appealing strategy for CO net reduction. However, it suffers from the inferior faradaic efficiency (FE), selectivity, and difficult modulation of hydrogen/carbon monoxide (H/CO) ratio. To address these issues, a series of magnesium-nickel (Mg-Ni) dual atomic catalysts with different Ni contents are fabricated on the nitrogen-doped carbon matrix (MgNi-NC DACs) by one-step pyrolysis.

The metal-semiconductor (M-S) contact is usually an Ohmic contact or a Schottky contact, which greatly affects the electronic properties of devices, and it remains a huge challenge to realize a low-resistance Ohmic contact in a metal-semiconductor junction (MSJ). Herein, we systematically studied the band structures, electrostatic potential, charge transfer, Schottky barrier height of carriers, effective carrier masses, and tunneling probability of carriers of a germanene (Ge)/GaAs MSJ. The transition from the Schottky to the Ohmic contact can be caused by applying certain biaxial strains or electric fields, which weakens the Fermi level pinning (FLP) effect and reduces contact resistance.
