Static and Dynamic Analysis of Porous Gas Bearings Lubricated With Air, Refrigerant R‐134a, Helium and Hydrogen

Lubrication Science, EarlyView.
ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

Review on Processing Control Strategy for Electrochemical Additive Manufacturing

MetalMat, EarlyView.
This review systematically summarizes recent progress in processing control strategies for ECAM, with three key regulation dimensions: current monitoring and closed‐loop control, temperature regulation, and electrolyte flow/nozzle design. The roles of these parameters in governing electrochemical kinetics, mass transport, deposition stability, and ...

Weak Solutions for a Class of Nonlocal Singular Problems Over the Nehari Manifold

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a nonlocal model of dilatant non‐Newtonian fluid with a Dirichlet boundary condition. By using the Nehari manifold and fibering map methods, we obtain the existence of at least two weak solutions, with sign information.

Practical Guide and Best Practices for Diffusion NMR Processing With GNAT

Magnetic Resonance in Chemistry, EarlyView.
A practical and reproducible workflow for diffusion‐NMR (DOSY) data analysis is introduced through a step‐by‐step GNAT tutorial. By establishing clear processing guidelines, validation strategies, and reporting standards, this work aims to reduce variability in diffusion measurements and promote more transparent, comparable, and reliable DOSY studies ...

Photothermal‐Expedited Ion Transport Kinetics for Efficient Electrocatalytic Hydrogen Evolution

National Materials, EarlyView.
The photothermal effect of two‐dimensional graphdiyne is explored via combined experiments and simulations and is further fully leveraged to synergistically expedite reactive ion transport kinetics and enhance intrinsic site activity toward a boosted electrocatalytic hydrogen evolution reaction (HER). The HER performance is thus elevated to rank at the
