Operations Research, 2006 This paper deals with the conflict between simplicity and optimality in searching for a stationary target whose location is distributed in two dimensions, thus continuing an analysis that was begun in World War II. The search is assumed to be of the “piled-slab” type, where each slab consists of a uniform search of some simple region.

Geometrically‐Screened, Sterically‐Hindered Additive for Wide‐Temperature Aqueous Zinc‐Ion Batteries
Advanced Functional Materials, EarlyView.A molecular‑engineering strategy combining steric hindrance tuning with geometric optimization identifies cellobiose as an ideal additive for aqueous zinc‑ion batteries, enabling stable Zn deposition across a wide temperature range from −30 to 50 °C. Abstract Aqueous zinc‐ion batteries (AZIBs) are emerging as a highly promising alternative to lithium ...

Advanced Functional Materials, EarlyView.Ni1‐Bi1 dual‐atom dopants are achieved for activating Ru lattices without blocking noble atoms. This model exhibits an ultralow overpotential of 11.4 mV and superb stability at 10 mA cm−2 toward hydrogen evolution reaction, enabling a proton exchange membrane water electrolyzer that needs only 2.233 V to reach 3.0 A cm−2 and operates stably at 1.0 A cm−

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties
Advanced Functional Materials, EarlyView.High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐

Advanced Functional Materials, EarlyView.A diisopropyl ether (DIPE)‐based, localized, high‐concentration electrolyte is developed to stabilize both electrodes in aqueous zinc batteries. By reducing water activity and promoting anion‐rich zinc‐ion solvation, it builds robust interphases at both the cathode and anode, ensuring uniform deposition, suppressed corrosion, and highly reversible ...

Column-Slab Connection In Timber Flat Slabs
, 2020 With the development of large cross laminated timber (CLT) plates, a new field of possibilities for timber construction has opened. Combined with the invention of a rigid, momentresisting connection between CLT plates, it is possible to create structures like it was so far only achievable with reinforced concrete. The CLT elements can be placed next to
