Imposing regularity conditions on a system of cost and factor share equations

open access: yes
Systems of equations comprising cost functions and first‐order derivative equations are often used to estimate characteristics of production technologies. Unfortunately, many estimated systems violate the regularity conditions implied by economic theory.

Camels as a Climate‐Resilient Linchpin for Sustainable Development in Global Drylands

open access: yesSustainable Development, EarlyView.
ABSTRACT Camels represent a significant, yet underutilized, asset for advancing integrated sustainable development in the world's expanding drylands. Previous reviews have examined camels' physiology, milk composition, or pastoral systems in isolation; this review examines their potential as a climate‐resilient linchpin for food systems by synthesizing

Microporous Self‐Assembled Pd(II) Tetrahedral Cages for Rapid and Reversible Multi‐Phase Sequestration of Iodine and Methyl Iodide

open access: yesSmall, EarlyView.
This work reports a family of microporous, self‐assembled tetrahedral coordination cages that efficiently capture iodine, polyiodides, and methyl iodide from vapor, aqueous, and organic media. The cages display exceptional uptake capacities, rapid kinetics, and high selectivity, enabling the first dynamic vapor‐phase iodine capture by coordination ...

Functional Chain Engineering in MOFs: Balancing Pore Size and Affinity for Noble Gas Separation

open access: yesSmall, EarlyView.
A series of mixed‐ligand metal‐organic frameworks (ML‐xC8) were synthesized by systematically incorporating C8 alkoxy substituents (C8BDC) into the IRMOF‐1 framework. As the C8BDC content increased, the pore size progressively decreased. ML‐80C8 (80% C8BDC) provided the optimal pore environment for selective Xe adsorption, exhibiting a markedly ...

Hydrogen‐Based Reduction of Hematitic Iron Ore in a Fluidized Bed Kinetic Reactor at Elevated Pressures

open access: yessteel research international, EarlyView.
This study investigates the reduction behavior of two international iron ores, including a synthetic hematite produced by oxidation of magnetite, in a novel fluidized‐bed kinetic reactor at elevated pressures. The reduction takes place at various temperatures (650°C, 700°C, and 750°C), and various hydrogen partial pressures (30, 55, and 80 vol% H2 ...
