Advanced Science, EarlyView.Herein, we propose a solar‐powered heavy metal trap (SPHT) for sludge disposal. The indoor experiments demonstrated that the sludge water content decreased from 90 % to 31 %, coupled with a decrease in heavy metal content to 6 % at most. Furthermore, the designed SPHT generated an initial potential of 0.10 V, and monitoring this hydrovoltaic potential ...

Famine Demography - An Introduction [PDF]
Most dictionary definitions of ‘famine’ equate it with food scarcity and widespread hunger. They tend to remain silent on the demographic aspects, although the extra mortality caused by famines offers one easy and obvious gauge for ranking famines.

An Embodied Paper‐Based Microfluidic Al‐Air Battery for Enduring Untethered Insect‐Scale Robots
Advanced Science, EarlyView.This work presents a centimeter‐scale microfluidic aluminum–air battery (MFAAB) with dual‐surface anode and F−‐mediated byproduct decomposition. The design enables a high capacity of 2697.05 mAh/g Al and delivers tens of milliwatts to power LEDs, motors, and a toy car.

Drought and famine relationships in Sudan: policy implications [PDF]
Sudan is one of the few countries where famine still persists. Why? What are the determinants of famine in Sudan? What is the role of drought, especially in the context of economic policy failure and war? Who is affected by famine?

Advanced Science, EarlyView.Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.

Famine process and famine policy
, 2002 Ahmednagar District, in Bombay Presidency, was affected - along with much of South India - by a major drought in 1876-78, leading to famine relief by the Government of Bombay and considerable emigration and mortality. Recent literature, however, has suggested that famine is a complex, human and long-drawn-out process, rather than a sudden, natural ...

Advanced Science, EarlyView.We synthesized a high‐performance balanced ambipolar OECT polymer, P(gTDPPSe), via selenophene π‐bridge engineering. The selenophene π‐bridge enhances backbone planarity and optimizes the energy levels for doping, enabling high and balanced p/n‐type transconductance‐a key factor for high‐gain complementary inverters.
