Storage of potato tubers at low temperature affects their metabolism and may alter their phytochemical properties. There is a need to elucidate the changes in antioxidant compounds, activity and enzymes during storage of tubers. Eleven Indian potato varieties were evaluated for antioxidant parameters, after 0, 30, 60 and 90 days of storage at room temperature, 15 °C and 4 °C. Total phenolics(0.0786–0.1546 mg gallic acid equivalents·g^(-1)FW) and vitamin C content(0.0828–0.2416 mg·g^(-1)FW) varied among the varieties and were different with storage temperature; their levels fluctuated during storage but remained above the initial level until the last day of observation. Phenolic acid profiling by UPLC identified 12 compounds among which the most abundant was chlorogenic acid followed by gallic acid, sinapic acid and ellagic acid. Except para-coumaric acid which decreased at 4 °C, all the phenolic acids increased with storage. Caffeic acid, chlorogenic acid, protocatechuic acid and gallic acid mostly correlated with total phenolic content(r = 0.456, 0.482, 0.588 and 0.620, respectively). Antioxidant activity against both DPPH and ABTS radicals increased during the initial days of storage and then dropped to a level comparable or lower than the original value,irrespective of the storage temperature. Correlation study revealed that chlorogenic acid, gallic acid and ferulic acid mostly contributed to antioxidant activity. Activity of both antioxidant enzymes, superoxide dismutase and ascorbate peroxidase, increased initially but then decreased to values lower than the initial level and were not influenced by storage temperature. Correlation with antioxidant activity indicated that the enhancement of reactive oxygen scavenging species in cold stored tubers could result mainly from ascorbate peroxidase activity. Our results demonstrate that storage temperature adversely influences the metabolism and the content of antioxidant compounds in potato tubers, with subsequent inc

在许多实际应用中,纺织品的疏水性和抗渗性非常重要。研究中,用六氟乙烷(C_2F_6)或六氟乙烷与氢气(H_2)或乙烯(C_2H_4)的混合物进行的等离子体表面氟化处理,被用来改善聚酯微纤织物的拒水性能。改变泵入气体的组分和处理工艺(即使用混合气体,还是两种气体依次使用)对材料表面进行的改性可通过测定材料表面接触角与滑动角以及用X-射线光电子谱(XPS)进行了分析。值得注意的是,用混合气体(C_2F_6加H_2或者C_2H_4)处理后,疏水性随着还原物质用量的增加而降低,而两步法(先用氢气或者乙烯气体处理后,再用C_2F_6处理)疏水性不随气体流速的改变而变化。通过测定一连串的水洗后的接触角和滑动角研究了被处理表面的稳定性。在等离子体C_2F_6中添加还原剂后,表面改性具有显著的水洗稳定性。

In this paper, charge-plasma-based tunnel FET is proposed by employing dual material gate with hetero gate dielectric technique and it is named hetero-dielectric dual material gate doping-less TFET（HD_DmG_DLTFET）. It is compared with conventional doping-less TFET（DLTFET） and dual material gate doping-less TFET（DmG_DLTFET） on the basis of analog and RF performance. The HD_DmG_DLTFET provides better ON state current（I_（ON） =94 μA/ μm）, I_（ON）/I_（OFF）（≈1.36×10^（13））, point（≈3 mV/dec） and average subthreshold slope（AV-SSD40.40 mV/dec）. The proposed device offers low total gate capacitance（C_（gg）/ along with higher drive current. However, with a better transconductance（g_m） and cut-off frequency（f_T）, the HD_DmG_DLTFET can be a good candidate for RF circuitry. The early voltage（V_（EA）/ and output conductance（gd/ are also moderate for the proposed device with comparison to other devices and therefore can be a candidate for analog *** all these simulation results and their study, it is observed that HD_DmG_DLTFET has improved analog/RF performance compared to DLTFET and DmG_DLTFET.
