European Journal of Organic Chemistry, EarlyView.Bridging the gap. Beyond deck functionalization, the ethylene bridges of [2.2]paracyclophanes offer a largely unexploited reactivity landscape. This review showcases strategies to functionalize these bridges and leverage them to build novel cyclophane architectures.

Solid Biofuel Usage and Households' Behavior Toward Energy Choice in Northwest Ethiopia
Energy Science &Engineering, EarlyView.This study analyzed household energy choice behavior in northwest Ethiopia using an integrated energy stacking and decision‐making framework. Evidence shows dominant reliance on solid biomass and a fuel‐stacking pattern, while urban residences, higher income, and education increase clean energy adoption, highlighting the need for pro‐poor, context ...

New radiocarbon dates from the Bapot-1 site in Saipan and Neolithic dispersal by stratified diffusion [PDF]
, 2010 The colonisation of the Mariana Islands in Western Micronesia is likely to represent an early ocean dispersal of more than 2000 km. Establishing the date of human arrival in the archipelago is important for modelling Neolithic expansion in Island ...

Charring Behaviour of Mass Timber: A Comparison of Thin Intumescent Coatings and Plasterboard
Fire and Materials, EarlyView.ABSTRACT This study compares the charring behaviour of mass timber under varied heating conditions when protected by either different thin intumescent coating types or fire‐rated plasterboard layers. Bench‐scale fire experiments were conducted using the Heat‐Transfer Rate Inducing System (H‐TRIS).

Food Chemistry International, EarlyView.In an aqueous alkaline medium, fatty acids (from the hydrolysis of triglycerides or freely present in the oil) are ionised in order to form emulsifiers (carboxylates) which will physically stabilise the prepared emulsion. The higher the free fatty acids content of the oil and alkalinity of the solution, the higher will be the stability of the prepared ...

Chronology and Demography: How Many People Lived in a Mega-Site? [PDF]
, 2016 Since the discovery of the huge dimensions of Trypillia BIVCI mega-sites, estimations about their population size have mainly resulted magnitudes which are as extraordinary for European prehistory as the dimensions of the sites themselves.
