Drag Coefficient In A Crystal Suspension

open access: yes, 2008
A single air bubble rising in xanthan gum crystal suspension has been studied experimentally. The suspension was made by different concentrations of xanthan gum solutions with 0.23 mm polystyrene crystal particles.

Creeping motion of a sphere in tubes filled with Herschel–Bulkley fluids

open access: yes, 1997
Previous numerical simulations for the flow of Bingham plastics past a sphere contained in cylindrical tubes of different diameter ratios are extended to Herschel–Bulkley fluids with the purpose of comparing them with experiments.

Coexistence of Large Nernst Effect and Axis‐Dependent Conduction Polarity in Semimetal MoSi2

open access: yesAdvanced Electronic Materials, EarlyView.
MoSi2${\rm MoSi}_2$ is a rare material in which axis‐dependent conduction polarity (ADCP) and a large ordinary Nernst effect (ONE) coexist. The pronounced ONE (199μVK−1$199\,\umu \mathrm {V}\,\mathrm {K}^{-1}$) originates from nearly perfect carrier compensation, high mobility, and likely phonon drag, while ADCP arises from mixed‐dimensionality of the ...

Determination of skin friction on a rotating sphere in magnetic levitation

open access: yesRevista Brasileira de Ensino de Física
A simple and inexpensive experimental procedure is proposed to investigate the skin friction caused by air in a rotating sphere. A device using a magnetic field keeps the sphere levitating.

Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

open access: yesAdvanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Farmers' Preferences for Gene Editing Crops and Influencing Factors

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Gene editing (GE) is gaining momentum worldwide, but limited data on UK farmers' preferences hinders our understanding of its potential impact amid deregulation debates. Based on a survey of 200 English arable farmers, we employ a Latent Class Analysis and Multinomial Logit regressions to investigate current preferences for GE crops.

Constructing and Validating New County‐Level Cultural Capital Indices for Applied Policy Analysis: Evidence From SNAP Take‐Up

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Cultural capital influences a wide range of social and economic outcomes, yet quantitative measures suitable for policy analysis remain limited. We develop county‐level cultural capital indices for the US based on Bourdieu's framework of objectified, embodied, and institutionalized cultural capital.

Advancing European Plant Variety Registration: Data‐Driven Insights and Stakeholder Perspectives

open access: yesAgribusiness, EarlyView.
ABSTRACT Efficient plant variety registration is crucial for fostering innovation in the European Union, yet the current regulatory framework is complex and faces calls for reform. This study provides data‐driven evidence to inform the ongoing legislative debate by employing a mixed‐methods approach.
