A significant challenge for energy storage technologies is to realize battery-level energy density and capacitor-level durability and
power density in one device. By introducing an electrolyte composed of an anionic catholyte and a cationic anolyte into a symmetric
carbon-based supercapacitor configuration, a hybrid electrochemical battery-supercapacitor system using soluble redox species...

Rainfall runoff erosivity (R) is one key climate factor that controls water erosion. Quantifying the effects of climate change–induced erosivity change is important for identifying critical regions prone to soil erosion under a changing environment. In this study we first evaluate the changes of R from 1970 to 2090 across...
A highly-digital technique is proposed for excess loop delay (ELD)
compensation in multi-bit continuous-time ΔΣ modulators. A digitally
controlled reference switching matrix is used to replace the power-hungry
signal adder and extra DAC driving the quantizer, which are
commonly used in ELD compensation. With the proposed technique,
the feedback DAC...
A new incremental ADC is proposed which extends the order of a
conventional incremental ADC from N to (2N-1) by way of a two-step
operation. For a given conversion time, the duration of each step can be
optimized. For an Nth-order IADC, the performance is equivalent to that
of a...
In this letter, a simple and highly efficient successive-approximation
Registers (SAR) ADC realization is proposed. It requires an op-amp,
a comparator and only three equal-valued capacitors. The proposed
scheme is insensitive to the capacitor parasitics, and has a small
capacitance spread. With an oversampled scheme, it also allows
noise-shaping the...
A global-scale three dimensional atmospheric transport and chemistry model was applied to simulate transpacific transport of Benzo[a]pyrene (BaP) emitted from Asia. The model results were compared with observations at six monitoring sites. The annual mean and seasonal variation of transport patterns and the contributions of different Asian source regions to...
