One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that

Impacts of Social Assistance During the COVID‐19 Pandemic in Poor Remote Communities

open access: yesJournal of International Development, EarlyView.
ABSTRACT Providing social assistance to poor populations in remote communities in times of crises, such as pandemics, is challenging but crucial. This paper examines how food assistance during the COVID‐19 pandemic affected people's behaviour, using our surveys among over 400 rural communities without road access in the Peruvian Amazon. Food assistance
