Two-Phase Multi-Objective Inverse Design of Rotary Burnishing Regimes and Compliant-Roller Tools: Full-Factorial Grid Enumeration and NSGA-II

Applied System Innovation
The design of regular microreliefs requires process and tool variables that satisfy surface-coverage, lubricant-retention, and residual-depth requirements.

Chitin‐Derived Carbon‐Metal Functional Materials

Advanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Rotary Burnishing of Cylindrical Surfaces: Kinematic Layout, Relative Curvature Tensor, and Contact-Conformity Classification

Mathematical and Computational Applications
Rotary and vibro-rotary burnishing create regular arrays of imprints whose geometric interaction depends on the pitch, indentation depth, and relative curvature of the tool–workpiece pair. This paper develops a unified kinematic–curvature model that maps

The Effect of Hydrophilic Headgroup Chemistry on Peptoid‐Directed Mineralization of CaCO3

Advanced Functional Materials, EarlyView.
Amphiphilic peptoids alter the pathway and outcome of calcium carbonate crystallization, which progresses through amorphous calcium carbonate (ACC) to vaterite to calcite rhombs in the absence of peptoids. In contrast, amine‐terminated peptoids produce vaterite disks and carboxyl‐terminated peptoids produce calcite mesocrystals.

A Physics-Informed Combinatorial Digital Twin for Value-Optimized Production of Petroleum Coke

Energies
Petroleum coke quality strongly influences refinery economics and downstream energy use, yet real-time control is constrained by slow quality assays and a 24–48 h lag in laboratory results.

Anti‐Inflammatory and Neuroactive Effects of Polymer‐Coated Iron Oxide Nanoparticles Functionalized With Interleukin 4 for Spinal Cord Injury

Advanced Healthcare Materials, EarlyView.
Polymer‐coated IONPs functionalized with IL‐4 display respective neuroactive and anti‐inflammatory actions on neural progenitor cells and macrophages/microglia in vitro. When examined chronically in a rat experimental model of spinal cord injury, rGO scaffolds carrying these nanosystems adequately integrate into the lesion, significantly reduce ...

Astronomically Constrained Third-Order Sequence Stratigraphy of the Eocene Eh₃ Member in the Lacustrine Biyang Depression, Central China

Applied Sciences
The middle Eocene represents a shift from the Early Eocene greenhouse climate to a subsequent cooling trend, during which orbital-scale forcing exerted a strong influence on continental depositional systems.

Oil and gas complexes and clusters: identification and monitoring

Вестник Пермского университета. Серия: Экономика, 2015
The need to identify and to organize the regional monitoring of industrial complexes and clusters is based on their strategically important role in the regional development. Legal documents and scientific publications do not properly cover the methods for identifying cluster members as well as for assessing the effectiveness of cluster policy.
