Summary: Additive manufacturing is a promising technique for manufacturing complex shapes without the need for tools. However, the resulting components have high surface roughness, which affects their performance in various applications. Chemical-based finishing processes have been developed to reduce surface roughness, but the lack of understanding of their fundamental mechanisms limits their practical applications. This review study explains the mechanisms of different finishing processes and discusses their current state and future perspectives. Additionally, it provides insights into selecting appropriate finishing processes based on component complexity and cost.

Summary: The thickness of carbon bricks plays a significant role in the longevity of a blast furnace. Chemical analysis, X-ray diffraction (XRD), and scanning electron microscopy (SEM)-energy-dispersive X-ray spectroscopy (EDS) were used to characterize the state of brittle carbon bricks and floating carbon bricks. High levels of K, Na, Cl, Zn, and Fe were found to be major causes of carbon brick erosion, with floating carbon bricks likely originating from the sidewall. Additionally, the source of Al2O3 in floating refractory and the consumption pathway of SiO2 and ZnO in residual iron were analyzed.

Summary: In drylands, wind erosion and vegetation interaction form an important feedback that encourages grass-to-shrub state transitions. Wind can also act as a forcing, directly reducing grass cover. This study examines the responses of a grass-shrub community after two extreme wind events, and finds that extreme events lead to increased root exposure and reduced greenness, particularly in areas with low grass cover. The difference between extreme wind events and common winds allows extreme winds to behave as endogenous forcings while common winds participate in an endogenous stabilizing feedback.

Summary: Through the use of Be-10 and Al-26 isotopes, the study found that erosion rates in the eastern Himalayan syntaxis region are influenced by deeply sourced materials and reworked sediments. Most samples showed that deeply sourced materials with high Al-26/Be-10 ratios did not perturb the Be-10 signals in river sediments, indicating that deep-sourced materials may have been removed from the basins before sample collection. However, the perturbation of reworked sediments was observed over a range of basin scales.

Summary: The detection of a gravitational-wave signal and subsequent electromagnetic transient from a neutron star merger in 2017 confirms that neutron star mergers are a source of r-process element production. The kilonova spectra of the merger transition from a blackbody illuminating heavy, r-process elements to a non-LTE regime where collisional and photoprocesses determine the ionization balance. Approximate methods are used when detailed cross section data is not available, and comparisons with more sophisticated collision calculations are important to evaluate their accuracy.

Summary: Changes in the structural-aggregate state, acidity, and carbon stocks of dark-humus podbels during their postagrogenic development under unmanaged fallow were studied. The study found that the aggregate state of the soil was restored after removal from agricultural use, with an increase in agronomically valuable aggregates. The soils became more acidic during vegetation restoration, with the most significant drop in pH occurring in the 20-yr-old fallow soil with the appearance of woody plants. Carbon stocks in the fallow soils tended to increase over time, reaching their maximum by the 85th yr of postagrogenic succession. However, the difference in carbon stocks between 20- and 85-yr-old fallow soils was not statistically significant. The bulk density of the plow layer in cultivated soil was higher than that in the fallow soils.

Summary: By studying soil samples from different slope directions along an elevational gradient in a mountain ecosystem, we found that soil bacterial diversity and microbial functions exhibit distinct elevational patterns, which are consistent across slope directions. The bacterial diversity shows a hump-shaped pattern, while microbial functions exhibit a linear increasing trend. Additionally, the beta diversity pattern of soil bacteria is significantly influenced by elevational distance decay relationships. Soil bacterial diversity patterns are determined by transitions in community assembly processes, whereas microbial functions are mainly influenced by bacterial community composition.

Summary: Soil respiration plays a crucial role in the global carbon cycle in arid and semi-arid regions, and is regulated by hydrothermal factors. This study examined the seasonal and diurnal dynamics of soil respiration in two typical ecosystems in northern China, and investigated their responses to precipitation, temperature, and drought. The results showed that soil respiration varied seasonally and diurnally, and its response to environmental factors depended on the ecosystem type and soil moisture status. Incorporating multiple factors into carbon cycle models can improve the simulation and prediction of carbon emissions in arid and semi-arid regions.

Summary: Lake drawdown areas, where sediment is exposed due to water level fluctuations, have a significant impact on the carbon cycle. This study examined microbial necromass carbon (MNC) content and its contribution to soil organic carbon (SOC) in different habitats within the drawdown area of Dongting Lake. The results showed that MNC content varied among habitats and was primarily influenced by carbon and nitrogen availability, plant biomass, clay content, and soil moisture. External factors, such as plant and soil properties, played a more crucial role in the long-term accumulation of MNC. These findings enhance our understanding of MNC stability in drawdown areas.
