Advances and Outlook of Nickel‐Based MOFs–LDHs Materials for Energy Conversion

Advanced Sustainable Systems, EarlyView.
In this graphical abstract, we present the pivotal gap between the activity and stability parameters as far as intergrated Ni‐based MOF/LDF electrocatalysts are concerned. For large scale application, these two parameters should be optimized and furthermore balanced in order to promote sustainable electrocatalytic hydrogen production.

Coralline algae in a naturally acidified ecosystem persist by maintaining control of skeletal mineralogy and size [PDF]

, 2016
To understand the effects of ocean acidification (OA) on marine calcifiers, the trade-offs among different sublethal responses within individual species and the emergent effects of these trade-offs must be determined in an ecosystem setting.

Crystal-chemistry and short-range order of fluoro-edenite and fluoro-pargasite: a combined x-ray diffraction and ftir spectroscopic approach [PDF]

, 2013
In this study we address the crystal-chemistry of a set of five samples of F-rich amphiboles from the Franklin marble (USA), using a combination of microchemical (EMPA), SREF, and FTIR spectroscopy methods. The EMPA data show that three samples fall into

Bio‐Based Piezoelectrets from Polylactic Acid and Natural Waxes: A Sustainable Approach for Energy Harvesting

Advanced Energy and Sustainability Research, EarlyView.
A novel polylactic acid/wax electret composite is developed, combining biodegradability with long‐term charge stability. The study investigates charge storage behavior, structural morphology, and thermal performance. Results reveal a notable charge retention recovery after thermal stress and exhibit stable surface potential over 2 kV. This eco‐friendly

Gypsum Gardens: Self‐Assembled Tubular Structures of Calcium Sulfate with Relevance for the Detection of Extraterrestrial Life

Angewandte Chemie International Edition, EarlyView.
Chemical gardens are self‐assembled architectures with “life‐like” morphologies that form in the absence of any biological activity. Here we show that such structures can also be obtained by contacting reservoirs of calcium and sulfate ions, under conditions that plausibly emulate those prevailing on early Mars.
