“…Fossil fuel consumption and global climate changes [1] in connection with air pollution have prompted research for alternative and clean energy sources [2][3][4][5]. The challenging theme of the ''hydrogen economy'' [6][7][8][9][10] has experienced a wide interest due to the possibility of direct conversion between chemical and electrical energy through an electrochemical reaction, a truly ''green process''.…”

New electrocatalytic materials based on mixed metal oxides: electrochemical quartz crystal microbalance characterization

et al. 2008

An electrochemical Quartz Crystal Microbalance (EQCM) was used to characterize a mixed metal oxide electrocatalyst, Ir 0.15 Sn 0.85 O 2 , for the Oxygen Evolution Reaction (OER) in acidic medium in the potential range of the pseudo-capacitance reaction, from 0.4 to 1.2 V versus Reversible Hydrogen Electrode (RHE). The EQCM gold tip was characterized in H 2 SO 4 0.05 M and HClO 4 0.1 M. Subsequently, Ir 0.15 Sn 0.85 O 2 powder, synthesized by a solgel route, was supported on the tip gold surface for investigations in the same media. The simultaneous measurements of mass variation and current density as functions of potential led to the identification of the chemical species involved in the mass transfer between the oxide and the acidic solution during the pseudo-capacitance reaction.

“…In the past century, reclaimed cropland has migrated from the Songnen Plain to the Sanjiang Plain [29]. In the last half century, changes in evolved agricultural policy [30], the increased food demand, and economic returns have led to the northward expansion of cropland in Sanjiang Plain along with changes in the cropland planting structure. Moreover, a large number of state-owned farms are located in this region.…”

Time Tracking of Different Cropping Patterns Using Landsat Images under Different Agricultural Systems during 1990–2050 in Cold China

et al. 2018

Rapid cropland reclamation is underway in Cold China in response to increases in food demand, while the lack analyses of time series cropping pattern mappings limits our understanding of the acute transformation process of cropland structure and associated environmental effects. The Cold China contains different agricultural systems (state and private farming), and such systems could lead to different cropping patterns. So far, such changes have not been revealed yet. Based on the Landsat images, this study tracked cropping information in five-year increments (1990–1995, 1995–2000, 2000–2005, 2005–2010, and 2010–2015) and predicted future patterns for the period of 2020–2050 under different agricultural systems using developed method for determining cropland patterns. The following results were obtained: The available time series of Landsat images in Cold China met the requirements for long-term cropping pattern studies, and the developed method exhibited high accuracy (over 91%) and obtained precise spatial information. A new satellite evidence was observed that cropping patterns significantly differed between the two farm types, with paddy field in state farming expanding at a faster rate (from 2.66 to 68.56%) than those in private farming (from 10.12 to 34.98%). More than 70% of paddy expansion was attributed to the transformation of upland crop in each period at the pixel level, which led to a greater loss of upland crop in state farming than private farming (9505.66 km2 vs. 2840.29 km2) during 1990–2015. Rapid cropland reclamation is projected to stagnate in 2020, while paddy expansion will continue until 2040 primarily in private farming in Cold China. This study provides new evidence for different land use change pattern mechanisms between different agricultural systems, and the results have significant implications for understanding and guiding agricultural system development.

Did climatic warming trigger the onset and development of yellow‐cedar decline in southeast Alaska*

Yellow cedar {Gbamaecyparis nootkatensis) is a valuable tree speeies that is experiencing an extensive forest decline on over 200 000 ha of unmanaged lorest in southeast Alaska. Biotic factors appear secondary and some abiotie factor is probably the primary eause of this naturally occurring deeline. A warming elimate, which coincided with the onset of extensive tree mortality about 100 years ago, may have triggered one of the possible abiotic causes such as freezing damage and/or soil toxieity.
