Efficient separation of electron–hole pairs is vitally crucial to enhancing the analytical performance paper-based photoelectrochemical (PEC) bioanalysis. Herein, a simple but effective strategy developed modulate photogenerated electrons and holes via introducing polar charge carriers-created (PCC) electric field induced by classical perovskite ferroelectric BaTiO3 (BTO). By inserting it between n-type WO3 nanoflakes p-type Cu2O (WO3 nanoflakes/BTO/Cu2O), photoelectrode endowed with...
Mercury (Hg) is a globally spread trace metal due to its long atmospheric residence time. Yet, our understanding of processes (e.g., redox reactions and deposition) driving Hg cycling still limited, especially in polar regions. The Antarctic continent, by virtue remoteness, the perfect location investigate absence significant local anthropogenic impact. Here, we present first 2 year record (2016-2017) total suspended particulate mercury (PHg) concentrations along with year-round...
Abstract To investigate the effects of both non-meltwater and meltwater-related post-depositional processes on chemical species within snow–firn pack, a research program, Program for Glacier Processes Investigation, was initiated in July 2002 by Tien Shan Glaciological Station, Chinese Academy Sciences. The seasonal variability ionic concentrations surface snow samples ion elution behavior pack were assessed from collected year-round 1011 pit at weekly intervals September 2003 through 2004....
Abstract Although mercury (Hg) is a neurotoxic metal of global relevance, its Antarctic biogeochemical cycles are not well characterized. Here, we present the total Hg (THg) distribution and stable isotopic fractionation between Zhongshan Station Dome A (1,248 km), in eastern Antarctica, to characterize THg sources controlling factors. Surface snow samples blocks similarly exhibited higher concentrations coastal interior sections than intermediate section. From (notably for 200 202 Hg),...
Mercury (Hg) enters terrestrial ecosystems through vegetation uptake, yet the sources, bioaccumulation, and influencing factors of Hg in Antarctic remain unclear. Cryptogams (e.g., mosses lichens) are conventional biomonitors major types polar regions. Here, we measured concentrations isotope compositions cryptogams from continental maritime Antarctica. The results show large variability (40 to 1128 ng/g) mass-independent fractionation (denoted by  Δ199Hg: -1.94...
ABSTRACT The stable oxygen isotope composition, major ions and isotopic compositions of strontium (Sr), neodymium (Nd) lead (Pb) in insoluble dust from recent surface snow samples along the transect Zhongshan Progress stations (located on Amery Ice Shelf, East Antarctica) to Dome A (Summit, were analysed. No previous fingerprinting studies have been conducted for this transect. These data used document provenances Antarctica up highest site, A, first time. coast displays an overall...
In this paper, the spatial autocorrelation microtremor array analysis is utilized to map deeply-buried subtle faults that have primary controls on geothermal reservoirs. We identified a low-velocity anomaly which approximately 50 m wide at about 550-1400 deep. A well drilled based later successfully produced hot water and further proved was caused by highly fractured zone depths from 700 1500 m. Our results clearly demonstrate survey method can be effectively structures for energy...
Volcanic signals recorded in the Antarctic and Greenland ice cores can provide useful information on past explosive volcanism its impact. In this study, we carried out a continuous sulfate analysis of 102.65 m East core (DT‐401, dated as 2682 years) identified 36 extensive volcanic eruption using Cole‐Dai's method, which gives an average 1.4 eruptions per century, consistent with results from Plateau Remote (PR‐B) core. When record is divided into three parts, latest millennium (1999–1000...
In this study, the concentrations of total mercury (THg) and ions deposited in surface snow pits eastern Antarctic along 29th inland route Chinese National Research Expedition were analysed. The THg ranged from 0.22 to 8.29 ng/L elevated detected regions higher altitudes (3000–4000 m). spatial distribution showed greater with mean <0.2–1.33 ng/L. coastal pit (29-A) summer layers than winter layers. records two (29-K 29-L) spanned decades indicated between late 1970s early 1980s during...
At Dome Argus, East Antarctica, the surface mass balance (SMB) from 2008 to 2013 was evaluated using 49 stakes installed across a 30×30 km area. Spatial analysis showed that at least 12 and 20 are needed obtain reliable estimates of SMB local scales (a few hundred square metres) regional (tens kilometres), respectively. The estimated annual mean 22.9±5.9 kg m−2 yr−1, including net loss by sublimation −2.22±0.02 yr−1 gain deposition 1.37±0.01 yr−1. Therefore, ca. 14.3% precipitation modified...
Abstract. Antarctic ice core nitrate (NO3-) can provide a unique record of the atmospheric reactive nitrogen cycle. However, factors influencing deposition and preservation NO3- at sheet surface must first be understood. Therefore, an intensive program snow sampling was made on traverse from coast to summit, Dome A, East Antarctica. Snow samples in this observation include 120 (top ∼ 3 cm), 20 pits with depths 150 300 cm, 6 crystal (the topmost needle-like layer A plateau). The main purpose...
Abstract The Chinese First Deep Ice-Core Drilling Project DK-1 has commenced at Kunlun station in the Dome A region, highest plateau Antarctica. During first season, within 28th National Antarctic Research Expedition (CHINARE) 2011/12 pilot hole was drilled and reamed order to install a 100 m deep fiberglass casing. In next 29th CHINARE 2012/13, ice-core drilling system installed, all auxiliary equipment connected commissioned. After filling with fluid ( n -butyl acetate), three runs of...
Abstract Stable isotope ratios (δ 18 O and δD) in Antarctic snow ice are basic proxy indices of climate core studies. The relation between the has important indicative significance for moisture sources. In general, fractionation characteristics two isotopes vary with different meteorological topographical conditions. This paper presents spatial temporal distribution meteoric water line (MWL) slopes along a traverse from Zhongshan Station (ZSS) to Dome A East Antarctica. It is found that...
Abstract A deep ice core was drilled at Dome A, Antarctic Plateau, East Antarctica, which started with the installation of a casing in January 2012 and reached 800.8 m 2017. To date, total 337 successful ice-core drilling runs have been conducted, including 118 to drill pilot hole. The time 52 days, eight days were required for down reaming hole, 44 coring. average penetration depths individual 1 3.1 hole coring, respectively. quality cores imperfect brittle zone (650−800 m). Some troubles...
Based on daily minimum, maximum, and mean surface air temperatures (T min, T max, mean) from the European Centre for Medium-Range Weather Forecast's reanalysis 1979 onwards (ERA Interim), accuracy of min max is assessed against in situ observations four automatic weather stations (Zhongshan, EAGLE, LGB69, Dome A) East Antarctica 2005 to 2008. ERA Interim generally shows a warm bias cool with an underestimation diurnal temperature range. The explains more than 84% annual variance, replicating...
