Performance of historical ferrocement specimens subjected to corrosive environments
Structural Concrete, EarlyView.Abstract Ferrocement is a type of thin wall‐reinforced concrete composed of hydraulic cement mortar reinforced with several layers of steel wire mesh. The material is used as a low‐cost construction and retrofit solution and allows the creation of very thin elements.

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.During synthesis of nitridogermanates, oxygen and carbon impurities lead to a variety of novel compounds—comprising carbodiimides and oxides—significantly expanding the chemistry of this compound class. Various novel compounds have been encountered by serendipity, due to small oxygen or carbon impurities, during the explorative studies to explore the ...

Effect of organic biocolourants on lightfastness and mechanical properties of polylactic acid
Coloration Technology, EarlyView.Abstract Most modern colourants are acquired from petroleum‐based sources or mining, which often causes environmental degradation. Consequently, alternative colouring solutions are sought, such as using biocolourants, which are organic colourants from bio‐based sources.
