Rare Metals, EarlyView.ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...

Social, Technological, Economic, and Policy Factors in the Circular Economy Transition in Brazil
Sustainable Development, EarlyView.ABSTRACT A well‐functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi‐structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing

Do digital platforms create entrepreneurial opportunities? Evidence from marginal areas
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary This article enters the debate on the effects of digital platforms on entrepreneurial opportunities by estimating whether the entry of a home‐sharing platform shapes entrepreneurial decisions in marginal areas. We add a novel perspective to the literature, as we contend that when economic conditions are unfavorable, digital ...

Small, EarlyView.This proteomic study examines how nanofibers affect lung macrophages by analyzing protein changes following exposure to various fibrous materials. Nanofibers triggered the release of inflammatory enzymes, and importantly, lysosomal content release was identified as an early event associated with frustrated phagocytosis. Seventeen sensitive and relevant

Iron Furnace Problem - What is the porosity distribution in the iron ore hopper? [PDF]
, 2011 In the processing of iron ore, pellets are funneled into a furnace and reduced by contact with a gas. We consider the problem of determining whether significant spatial segregation occurs within the furnace based on pellet size.
