Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

open access: yesAdvanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Characterization of surface contact modes of rough fractures in coal and their influence on seepage

open access: yesMeikuang Anquan
To further explore the control mechanism of contact characteristics of rough fracture surfaces in coal on coalbed methane (CBM) migration, enhance the understanding of CBM seepage laws, and better support the efficient exploitation of CBM, this study ...

The rough guide to evolution

open access: yes, 2009
Have you ever wondered what Charles Darwin would have had on his iPod? Or exactly how Cartman from South Park fits into the Theory of Evolution? 'The Rough Guide to Evolution' delves into all of this and more, from the life and works of the eminent ...

Zoledronic Acid in Reducing Clinical Fracture and Mortality after Hip Fracture.

open access: yes, 2007
BACKGROUND: Mortality is increased after a hip fracture, and strategies that improve outcomes are needed. METHODS: In this randomized, double-blind, placebo-controlled trial, 1065 patients were assigned to receive yearly intravenous zoledronic acid (at a

Numerical investigation on the influence of mesoscopic deformation on contact area and hydraulic aperture to fracture seepage

open access: yesDeep Underground Science and Engineering
Fluid flow through a single fracture is commonly described by the cubic law. However, deviations from this model are expected because natural fracture surfaces are rough and in contact with each other in discrete regions.

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Outer layer turbulence intensities in smooth- and rough-wall boundary layers

open access: yes, 2013
Clear differences in turbulence intensity profiles in smooth, transitional and fully rough zero-pressure-gradient boundary layers are demonstrated, using the diagnostic plot introduced by Alfredsson, Segalini & Örlü (Phys. Fluids, vol.
