Advanced Materials, EarlyView.We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Advanced Materials, EarlyView.Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Leveraging Earth Flyby Using E-sail with Attitude Constraints
Guidance, Navigation and ControlThe use of a single gravity assist maneuver can reduce the amount of velocity change required from a conventional spacecraft thruster to carry out complex interplanetary missions. In this context, the technique known as the V-infinity leveraging maneuver

Inverse Design of Amorphous Materials With Targeted Properties
Advanced Materials, EarlyView.AMDEN is a diffusion model framework for the inverse design of amorphous materials with targeted properties. By incorporating Hamiltonian Monte Carlo refinement into the denoising process, the framework overcomes the challenge of generating thermally relaxed disordered structures.

"INFINITY CAN NEVER BE EXPRESSED, SHOWN, DRAWN, OR PICTURED!": PRIMARY SCHOOL STUDENTS' PERCEPTIONS AND MISCONCEPTIONS OF INFINITY [PDF]
, 2012 Sonsuzluk, gerçek ve potansiyel sonsuzluk olmak üzere ikiye ayrılmaktadır. Eski zamanlardan beri, potansiyel sonsuzluğun matematiksel sonsuzluk olduğu kabul edilmektedir. Sayı kümeleri ise, matematiksel sonsuzluğu içeren kavramların başında gelir.

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells
Advanced Materials, EarlyView.Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures
Advanced Materials, EarlyView.Multiscale modeling is employed to investigate the functionality of a light‐controlled, tunable magnonic crystal based on spin‐crossover Fe‐pz molecules integrated with a monolayer of CrSBr. Ab initio simulations confirm that the molecules remain functional on the CrSBr surface, while a semiclassical elastic model demonstrates that light‐induced ...
