This paper reports about the lab scale results obtained by using stabilized bottom ash (SBA) from an Italian municipal solid waste incinerator as aggregates in cement-bound mixes and asphalt concretes for road pavements. The investigation focused on SBA content. From the road construction point of view, performance related to compaction, volumetric and mechanical properties were assessed. The environmental aspects were investigated performing leaching tests. The results suggested that SBA satisfied the environmental Italian law for reuse of non-hazardous waste but affected significantly the stress-strain behavior of the final products. Therefore a maximum percentage of 10% was suggested.

Achieving sensors that can sensitively and selectively quantify levels of analytes in complex biofluids such as blood remains a significant challenge. To address this, we synthesized an array of isolated carbon nanochannels on a flat gold electrode that function as molecular sieves to prevent protein fouling and eliminate the need for antifouling layers. Utilizing a two-step pulsed technique, a reductive pulse expels negative interferences and fouling molecules followed by an oxidative pulse that oxidizes glucose at the bottom of the channel and on the gold surface.

The application of classic foaming agent faces several issues, including excessive use of defoaming agent, inadequate defoaming, pipeline blockage due to silicone oil precipitation, and high development cost of the foaming agent. To address the aforementioned issues, a novel intelligent foaming agent was created. This resulted in the development of a new intelligent foaming and discharging agent system.

Water is one of the most important influences on slope stability in open pit mines. In order to solve the problem of slope stability analysis in multi-aquifer open pit mines, the open pit mine in Block I of Thar Coalfield in Pakistan with multiple aquifers was taken as the research background. The groundwater flow field at different excavation phases was analyzed by numerical simulation method.

The controlled formation and stabilization of nanoparticles is of fundamental relevance for materials science and key to many modern technologies. Common synthetic strategies to arrest growth at small sizes and prevent undesired particle agglomeration often rely on the use of organic additives and require non-aqueous media and/or high temperatures, all of which appear critical with respect to production costs, safety, and sustainability. In the present work, we demonstrate a simple one-pot process in water under ambient conditions that can produce particles of various transition metal carbonates and sulfides with sizes of only a few nanometers embedded in a silica shell, similar to particles derived from more elaborate synthesis routes, like the sol-gel process.

The interface between the perovskite layer and the electron transport layer is an extremely important factor that cannot be ignored in achieving high-performance perovskite photovoltaic technology. However, the void defects of the interface pose a serious challenge for high performance perovskite solar cells (PSCs). To address this, we report a polydentate ligand reinforced chelating strategy to strengthen the stability of the buried interface by managing interfacial defects and stress.
