Traditionally taught students learn; actively engaged students remember

science instruction

Franklin SV, Sayre EC.
GSID: tkv1C9Gp_rsJ
SV Franklin, EC Sayre, JW Clark - American Journal of Physics, 2014 - aapt.scitation.org

A common narrative in physics education research is that students taught in lecture-based classes learn less than those taught with activity-based reformed methods. We show this …

Note: A monoenergetic proton backlighter for the National Ignition Facility.

The Review of scientific instruments

Rygg JR, Zylstra AB, Séguin FH, LePape S, Bachmann B, Craxton RS, Garcia EM, Kong YZ, Gatu-Johnson M, Khan SF, Lahmann BJ, McKenty PW, Petrasso RD, Rinderknecht HG, Rosenberg MJ, Sayre DB, Sio HW.
PMID: 26628185
Rev Sci Instrum. 2015 Nov;86(11):116104. doi: 10.1063/1.4935581.

A monoenergetic, isotropic proton source suitable for proton radiography applications has been demonstrated at the National Ignition Facility (NIF). A deuterium and helium-3 gas-filled glass capsule was imploded with 39 kJ of laser energy from 24 of NIF's 192...

Liquid crystal seed nucleates liquid-solid phase change in ceria nanoparticles.

Physical chemistry chemical physics : PCCP

Sayle TX, Sayle LW, Sayle DC.
PMID: 25578038
Phys Chem Chem Phys. 2015 Feb 14;17(6):4441-7. doi: 10.1039/c4cp05499g.

Molecular dynamics (MD) simulation was used to explore the liquid-solid (crystal) phase change of a ceria nanoparticle. The simulations reveal that the crystalline seed, which spontaneously evolves and nucleates crystallisation, is a liquid rather than a solid. Evidence supporting...

Hydrodynamic instabilities can cause capsule defects and other perturbations to grow and degrade implosion performance in ignition experiments at the National Ignition Facility (NIF). Here, we show the first experimental demonstration that a strong unsupported first shock in indirect...

Experiments have recently been conducted at the National Ignition Facility utilizing inertial confinement fusion capsule ablators that are 175 and 165  μm in thickness, 10% and 15% thinner, respectively, than the nominal thickness capsule used throughout the high foot...

On possible extensions of X-ray crystallography through diffraction-pattern oversampling.

Acta crystallographica. Section A, Foundations of crystallography

Miao J, Sayre D.
PMID: 11058847
Acta Crystallogr A. 2000 Nov;56:596-605. doi: 10.1107/s010876730001031x.

It is known that sampling the diffraction pattern of a finite specimen, at a spacing somewhat finer than the Nyquist spacing (the inverse of the size of the diffracting specimen), corresponds to generating a no-density region surrounding the electron...

Oxygen transport in unreduced, reduced and Rh(III)-doped CeO2 nanocrystals.

Faraday discussions

Sayle TX, Parker SC, Sayle DC.
PMID: 17326580
Faraday Discuss. 2007;134:377-97; discussion 399-419. doi: 10.1039/b601521b.

Ceria, CeO2, based materials are a major (active) component of exhaust catalysts and promising candidates for solid oxide fuel cells. In this capacity, oxygen transport through the material is pivotal. Here, we explore whether oxygen transport is influenced (desirably...

BACKGROUND: Human solid tumors that are hard or firm on physical palpation are likely to be cancerous, a clinical maxim that has been successfully applied to cancer screening programs, such as breast self-examination. However, the biological relevance or prognostic...

Viscous reduction of turbulent damage in animal cell culture.

Biotechnology and bioengineering

Croughan MS, Sayre ES, Wang DI.
PMID: 18587994

Animal cells are exposed to turbulent fluid flow in many cell culture processes. If the turbulence in the flow is sufficiently strong, the cells will be damaged or killed by fluid-mechanical forces. Through an increase in viscosity, the turbulence...
