    Seawater carbonate chemistry and net community calcification, production and respiration of coral reef (2020)
    PANGAEA
    Details
    Publication Date: 2024-03-15
    Description: Previous studies have found that calcification in coral reefs is generally stronger during the day, whereas dissolution is prevalent at night. On the basis of these contrasting patterns, the diel variations of net community calcification (NCC) were monitored to examine the relative sensitivity of CaCO3 production (calcification) and dissolution in coral reefs to ocean acidification (OA), using two mesocosms that replicated a typical subtropical coral reef ecosystem in southern Taiwan. The results revealed that the daytime NCC remained unchanged, whereas the nighttime NCC decreased between the control (ambient) and treatment (OA) conditions, suggesting that carbonate dissolution could be more sensitive to OA than coral calcification. The average sensitivity of the integrated daily NCC to changes in the seawater saturation state (Omega a) was estimated to be a reduction of 54% in NCC per unit change in Omega a, which is consistent with the global average. In summary, our results support the prevailing anticipation that OA would lead to a reduction in the overall accretion of coral reef ecosystems. However, increased CaCO3 dissolution rather than decreased coral calcification could be the dominant driving force responsible for this OA-induced reduction in NCC.

    Description: Recent studies show that typhoons have profound effects on phytoplankton assemblages along their tracks, but it is difficult to quantitatively estimate nutrient supply after a typhoon's passage due to a lack of nutrient information before and after the arrival of a typhoon. During the passage of Typhoon Morakot (July 22 to Aug. 26, 2009), we conducted pre- and post-typhoon field cruises to study nutrient supply in the Southern East China Sea (SECS). The results showed nitrate and phosphate supplies to the water column in the SECS after the typhoon's passage were 5.6 × 1011 g-N/day and 7.8 × 1010 g-P/day which were significantly higher than those before the typhoon occurred (nitrate supply = 1 × 109 g-N/day, phosphate supply = 1.6 × 108 g-P/day). We conclude from this data, and after consulting the available physical data, that the highest nitrate concentration was caused by strong upwelling and/or vertical mixing, and input of nutrient-replete terrestrial waters. The nitrate and phosphate input related to the passage of Typhoon Morakot can account for approximately 86% and 87% of summer nitrate and phosphate supplies to the southern East China Sea.

    Research on Quick Polishing of CVD Diamond Film (2007)

    Notes: Polycrystalline CVD diamond film possesses many advanced physical and mechanicalproperties which makes it a very important engineering material. However, high hardness value andextreme brittleness have made CVD diamond film a very difficult material to be machined byconventional grinding and polishing processes. In the present research, diamond wafers were pretreatedwith RIE in an attempt to weaken the top layer and pave the way for subsequent thermochemicallypolishing. It was found that the diamond grains were anisotropically etched and somehigh aspect ratio pillar-like micro-structures were formed during the RIE process. These micropillarsare relatively easy to be ruptured and removed by the subsequent polishing process. Theresults showed that this method could effectively speed up the polishing of CVD diamond films

    Notes: ZnO/Diamond structure has attracted a lot of attentions and heavy investment recently justbecause diamond has the capability of producing very high surface acoustic wave (around10,000m/s). In this present study, the microwave chemical vapor deposition (CVD) method wasemployed to produce diamond films on silicon single crystal. Thermo-chemical polishingexperiments were then conducted on the obtained diamond films. The underlying material removalmechanisms, microstructure of the machined surface and related machining conditions were alsoinvestigated. Thermo-chemical polishing was proved to be able to remove the diamond film veryeffectively (4.8μm deep of diamond film was removed in 30 minutes when polishing at 550oC and5.7m/s). The material removal rate was increased with polishing speed and pressure. Higher polishingtemperature would improve the chemical reaction and result in better surface finish

    Material Removal Mechanisms Involved in Rotary Ultrasonic Machining of Brittle Materials (2007)
    s.l. ; Stafa-Zurich, Switzerland
    Key engineering materials Vol. 329 (Jan. 2007), p. 391-396

    Notes: Rotary ultrasonic machining (RUM) is considered to be a very effective and relativelyaccurate way to drill deep holes in brittle materials. Although brittle fracture (micro chipping) is thedominant material removal mechanism utilized by the RUM process, poor surface roughness anddeep penetrated cracks are the consequence if the machining parameters are not properly controlled.To ensure the quality of the generated surface and to improve the process efficiency, efforts havebeen made in this study to correlate the material removal mechanisms, surface integrity and tool wearinvolved in the RUM process. Diamond-impregnated tools were used in the experiment and theultrasonic vibration frequency was kept at 20 kHz. Three major material removal modes namely,impact mode, grinding mode and erosion mode were found to be the dominant removal processes atthe tool tip, around the diamond wheel and around the steel sleeve respectively. It was also foundthat, during the grinding/erosion processes, the bonding material of the wheel was first eroded awayand left big part of diamond grits well-exposed. Pull-out and/or fracture are normally theconsequence of these exposed diamond grits due to the lack of support and protection
