Khalet al-Jam’a. A Middle Bronze and Iron Age necropolis near Bethlehem (Palestine) [PDF]
, 2015 During Spring 2013, the MOTA-DACH Office of Bethlehem was informed of the retrieval of a tomb during the construction of an industrial area roughly 2.2 Km south-east of the Basilica of the Nativity on the Hindaza hill slope called Khalet al-Jam’a ...

Chemoselective Sequential Polymerization: An Approach Toward Mixed Plastic Waste Recycling
Advanced Functional Materials, EarlyView.Inspired by biological protein metabolism, this study demonstrates the closed‐loop recycling of mixed synthetic polymers via ring‐closing depolymerization followed by a chemoselective sequential polymerizations process. The approach recovers pure polymers from mixed feedstocks, even in multilayer formats, highlighting a promising strategy to overcome a

Advanced Functional Materials, EarlyView.This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer
Advanced Functional Materials, EarlyView.Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Advanced Functional Materials, EarlyView.Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Une statue d’Epona en tôle de bronze sur modèle en bois à Saint-Valérien (Yonne)
Revue Archéologique de l’Est, 2013 Partial exploration (1,7 hectares) of a large village close to Sens has revealed enclosures and wooden constructions, some containing forges, close to a large galleried courtyard. The stages of development during the 1st and 2nd centuries were discerned,
