Mercury is a threatening pollutant in food, herein, we developed Tb3+-nucleic acid probe-based label-free assay for mix-and-read, rapid detection of mercury pollution. The utilized the feature light-up fluorescence terbium ions (Tb3+) via binding with single-strand DNA. ion, Hg2+ induced thymine (T)-rich DNA strand to form double-strand structure (T-Hg2+</s...

In order to assess the thermal stability of polar ice deposits, we present model calculated temperatures of flat surfaces and surfaces within bowl-shaped and flat-floored polar impact craters on Mercury and the Moon. Our model includes appropriate insolation cycles, realistic crater shapes, multiple scattering of sunlight and infrared radiation, and depthand temperature-dependent regolith therm...

Two ion-inertial scale magnetic flux ropes are identified in the Juno field measurements dawnside Jovian magnetotail. Previously reported plasmoids this region had typical diameters of several radii (RJ). However, events here only ∼0.15–0.19 RJ diameter, assuming that they move at local Alfven speed. Using plasma density determined by Waves instrument, calculated to be on order ion inertial len...

Elemental mercury (Hg(0)) in flue gases can be efficiently captured by mercury chloride (HgCl2) solution. However, the absorption behaviors and the influencing effects are still poorly understood. The mechanism of Hg(0) absorption by HgCl2 and the factors that control the removal were studied in this paper. It was found that when the mole ratio of Cl(-) to HgCl2 is 10:1, the Hg(0) removal effic...

Two modified passive samplers were evaluated at multiple field locations. The sampling rate (SR) of the modified polyurethane foam (PUF)-disk passive sampler for total gaseous mercury (TGM) using gold-coated quartz fiber filters (GcQFF) and gaseous oxidized mercury (GOM) using ion-exchange membranes (IEM) were 6.4 ± 1.4 and 15.3 ± 0.3 m(3) day(-1), respectively. The relative percent difference ...

An economical mesoporous aluminosilicate was synthesized with microcline as starting material and the precursor 13X zeolite as seed for crystal structure on mesoporous walls. In this method, a mixture of microcline and Na2CO3 with a molar ratio of 1:1.05 was first calcined at 1093 K for 2.5 h. The calcined materials were mixed with 35 ml C16TMABr aqueous solution (containing 8.2 g C16TMABr) and...
