Fundamentals, properties and applications of solid catalysts prepared by solution combustion synthesis (SCS)

Abstract: The recent progress in solution combustion synthesis (SCS)-based preparation approaches in the synthesis of solid catalysts is discussed. This integrated overview includes not only the current understanding of the SCS chemistry and catalyst properties but also catalyst applications. SCS-based methods have had a variety of applications in heterogeneous catalysis including oxidation reactions, exhaust emission control, hydrogenation reactions, hydrogen production, and photocatalytic processes. The effects of using the fuel as chelating agent and reducing agent for the production of nanosized catalysts are also presented. Finally, the future of this important topic is discussed.

Long-term thermal sensitivity of Earth’s tropical forests

Abstract: The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important predictor of aboveground biomass (−9.1 megagrams of carbon per hectare per degree Celsius), primarily by reducing woody productivity, and has a greater impact per °C in the hottest forests (>32.2°C). Our results nevertheless reveal greater thermal resilience than observations of short-term variation imply. To realize the long-term climate adaptation potential of tropical forests requires both protecting them and stabilizing Earth’s climate.

Relationship between BMI, total testosterone, sex hormone-binding-globulin, leptin, insulin and insulin resistance in obese men

Abstract: The objective of this work was to evaluate the relationship between sex steroid hormones, sex hormone-binding-globulin, leptin, insulin and insulin resistance in obese men. Anthropometrical indexes...
