Rev Sci Instrum. 2017 May;88(5):053101. doi: 10.1063/1.4982034.

A Velocity Map Imaging (VMI) spectrometer has been designed and integrated with an electrostatic ion beam trap to study delayed electron emission from trapped polyatomic anions upon photodetachment. The VMI spectrometer is small in size and can record a...

Polypeptide pattern and enzymic character of vacuoles isolated from barley mesophyll protoplasts.

PMID: 24232646
Planta. 1986 Nov;169(3):345-55. doi: 10.1007/BF00392130.

Intact chloroplasts and vacuoles were isolated from mesophyll protoplasts of barley. The chloroplasts occupied about 15% of the cellular volume and contained 75% of the protein, whereas the vacuoles occupied about 80% of the volume and contained less than...

Coupled cyclic electron transport in intact chloroplasts and leaves of C3 plants: Does it exist? if so, what is its function?.

Photosynthesis research

Heber U, Gerst U, Krieger A, Neimanis S, Kobayashi Y.
PMID: 24301592
Photosynth Res. 1995 Nov;46(1):269-75. doi: 10.1007/BF00020440.

Transthylakoid proton transport based on Photosystem I-dependent cyclic electron transport has been demonstrated in isolated intact spinach chloroplasts already at very low photon flux densities when the acceptor side of Photosystem I (PS I) was largely closed. It was...

Metal nanoparticle based all-optical photothermal light modulator.

ACS nano

PMID: 24437364
ACS Nano. 2014 Feb 25;8(2):1893-8. doi: 10.1021/nn406389f. Epub 2014 Jan 23.

We present a simple scheme for the manipulation of light intensity by light mediated by a dissipative process. The implementation employs the heat released by an optically excited plasmonic metal nanoparticle to control the size of an isotropic bubble...

Photosystem I-dependent cyclic electron transport is important in controlling Photosystem II activity in leaves under conditions of water stress.

Fam Med. 2015 Mar;47(3):187-93.

BACKGROUND AND OBJECTIVES: Understanding how nonphysician health care providers (NPHCPs) teach medical trainees is integral to optimizing family medicine education. The objective of this study was to examine the teaching roles, level of preparation and support, and the challenges...

Thermal diffusivity measured using a single plasmonic nanoparticle.

Physical chemistry chemical physics : PCCP
