Summary: This paper proposes a de-icing fiber permeable asphalt mixture (DFPM) that satisfies the requirements of rapid drainage and ice melting in different seasons. Various performance tests were conducted to evaluate the permeability, de-icing properties, and pavement performance of different mixtures. The results show that the addition of de-icing agents and fibers has minimal effect on water permeability. The incorporation of de-icing agents improves high temperature performance but negatively impacts low temperature behavior and water stability, which can be compensated by the addition of fibers. DFPM with 0.3% fibers and 5% de-icing agent demonstrates superior performance and cost-effectiveness, making it recommended for practical applications.

Summary: This study evaluates the suitability of using the finite volume method to quantify transient energy and mass fluxes on frozen surfaces compared to the traditional glaciological energy balance approach. The methods were applied to datasets from a glacier in the semi-arid Andes and an Antarctic ice shelf, estimating the impact of time-varying surface irradiation, wind velocity, air temperature, and humidity on temperature, liquid water, and heat fluxes over a 30-month period. The results of the energy and mass balances were validated against previously published global balances and meteorological datasets.

Summary: Electrical-thermal technique is a promising method for melting snow on asphalt pavement. This study proposes a method to improve melting efficiency by combining thermal conductive asphalt concrete and electrical-thermal system. The results show that the thermal conductivity of the TCAC reaches a peak value when the steel slag volume content is 60%, and the road performance parameters meet the specification requirements. The snow melting effect of TCAC is better than that of ordinary asphalt concrete, and the surface temperature of the test road can be well predicted and evaluated by a neural network with an error within 1 degree Celsius.

Summary: This study assessed the long-term road performance and deicing longevity of self-ice-melting asphalt pavements containing salt-storage materials. The results showed that an increase in dry-wet cycles and freeze-thaw cycles decreased water stability, high-temperature stability, and low-temperature crack resistance of the pavements. Factors such as void ratio, temperature, vehicle load, crack, and MFL content influenced salt precipitation rates. Based on these findings, a deicing longevity prediction model was established.

Summary: Solar harvesting systems applied to asphalt roads use pipes or coils installed below the surface to collect heat from solar irradiation and convert it into thermal gradients for electricity supply. The design of asphalt mixes is crucial, with attention needed to avoid deformable materials due to high in-service temperature rutting potential. This study investigates the anti-rutting potential of specific asphalt layers designed based on thermal properties, finding that improvements in mix constituents and properties are required to meet deformation acceptance criteria.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Summary: This study found that decorating subwavelength arrays with SiO2 quasi-nanolenses (qNL arrays) can enhance the absorption of the solar spectrum. Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
