Advanced Energy and Sustainability Research, EarlyView.A‐site and B‐site doped strontium ferrite‐type Ruddlesden–Popper oxides are evaluated as CO2 sorbents for glycerol‐based hydrogen production via sorption‐enhanced steam reforming. A Sr1.4Ca0.6Fe0.9Ni0.1O4−δ composition forms an active Sr3Fe2O7 phase, achieving ≈95 vol% H2 purity and over sixfold longer CO2 prebreakthrough time (tpb) than its perovskite

Lucas Numbers with Lehmer Property
, 2015 A composite positive integer n is Lehmer if (n) divides n-1, where (n) is the Euler's totient function. No Lehmer number is known, nor has it been proved that they don't exist. In 2007, the second author [7] proved that there is no Lehmer number in the Fibonacci sequence.

Precise Real‐Time Measurement of Liquid Viscosity Using Digital Video Data
Advanced Intelligent Systems, EarlyView.Frame‐by‐frame image similarity analysis is employed to obtain the viscosity of moving liquids in real time. The method allows for online implementation even in harsh environments, replacing complex and invasive experiments. Quantitative knowledge of liquid viscosity is of fundamental importance in many areas of materials synthesis and processing ...

Self‐Healing Materials from Electronically Integrated Microscopic Robots
Advanced Intelligent Systems, EarlyView.Submillimeter robots can use electronically controlled electrodeposition to assemble into a material structure. The resulting aggregate possesses ultralow density, high strength‐to‐weight ratio, and can heal from damage. Further afield, these results clear a path to materials that organize or adapt by directing matter and information at the microscale.
