Tuning the Lattice Parameter of InxZnyP for Highly Luminescent Lattice-Matched Core/Shell Quantum Dots.

ACS nano

Pietra F, De Trizio L, Hoekstra AW, Renaud N, Prato M, Grozema FC, Baesjou PJ, Koole R, Manna L, Houtepen AJ.
PMID: 27065247
ACS Nano. 2016 Apr 26;10(4):4754-62. doi: 10.1021/acsnano.6b01266. Epub 2016 Apr 14.

Colloidal quantum dots (QDs) show great promise as LED phosphors due to their tunable narrow-band emission and ability to produce high-quality white light. Currently, the most suitable QDs for lighting applications are based on cadmium, which presents a toxicity...

Convergence of the discrete dipole approximation. I. Theoretical analysis: erratum.

Journal of the Optical Society of America. A, Optics, image science, and vision

Yurkin MA, Maltsev VP, Hoekstra AG.
PMID: 26831394
J Opt Soc Am A Opt Image Sci Vis. 2015 Dec 01;32(12):2407-8. doi: 10.1364/JOSAA.32.002407.

We report and address the errors in the analysis of the weighted discretization in Section 2.F of our published paper [J. Opt. Soc. Am. A23, 2578 (2006)JOAOD61084-752910.1364/JOSAA.23.002578].

Mass balance of trichloroacetic acid in the soil top layer.

Chemosphere

Hoekstra EJ, de Leer EW, Brinkman UA.
PMID: 10901673
Chemosphere. 1999 Feb;38(3):551-63. doi: 10.1016/s0045-6535(98)00206-9.

Since the ban on the use of trichloroacetic acid (TCAA) as a herbicide in several countries, TCAA is still found ubiquitously in the environment. The presence of TCAA nowadays is suggested to originate mainly from the atmospheric degradation of...

Surgical Prevention and Treatment of Late Normal Tissue Injury.

Seminars in radiation oncology

Schraffordt Koops H, Hoekstra HJ.
PMID: 10717098
Semin Radiat Oncol. 1994 Apr;4(2):119-122. doi: 10.1053/SRAO00400119.

There is a definite increase in combined-modality treatment of malignancies. Surgery, radiation therapy and/or chemotherapy often are combined. A disadvantage is the increased risk for short- and long-term complications, especially radiation-induced damage to normal healthy tissue such as intestine...

Pulse advancement and delay in an integrated-optical two-port ring-resonator circuit: direct experimental observations.

Optics letters

Uranus HP, Zhuang L, Roeloffzen CG, Hoekstra HJ.
PMID: 17767325
Opt Lett. 2007 Sep 01;32(17):2620-2. doi: 10.1364/ol.32.002620.

We report experimental observations of the negative-group-velocity (v(g)) phenomenon in an integrated-optical two-port ring-resonator circuit. We demonstrate that when the v(g) is negative, the (main) peak of output pulse appears earlier than the peak of a reference pulse, while...

Desiccation Tolerance of Papaver dubium L. Pollen during Its Development in the Anther: Possible Role of Phospholipid Composition and Sucrose Content.

Plant physiology

Hoekstra FA, van Roekel T.
PMID: 16666359
Plant Physiol. 1988 Nov;88(3):626-32. doi: 10.1104/pp.88.3.626.

Developing pollen of Papaver dubium L. becomes functional and desiccation tolerant at approximately 2 to 1 days prior to anthesis, coincident with degradation of starch and a doubling of the amount of sucrose, the primary soluble carbohydrate present. When...

Imbibitional chilling injury in pollen: involvement of the respiratory chain.

Plant physiology

Hoekstra FA.
PMID: 16663516
Plant Physiol. 1984 Apr;74(4):815-21. doi: 10.1104/pp.74.4.815.

Chilling injury is sustained by dry pollen of Typha latifolia L. upon hydration in germination medium at 0 degrees C. This injury is evidenced as poor germination, low vigor, and depressed respiration. Isolated mitochondria showed multiple sites of impaired...

Convergence of the discrete dipole approximation. I. Theoretical analysis.

Journal of the Optical Society of America. A, Optics, image science, and vision

Yurkin MA, Maltsev VP, Hoekstra AG.
PMID: 16985542
J Opt Soc Am A Opt Image Sci Vis. 2006 Oct;23(10):2578-91. doi: 10.1364/josaa.23.002578.

We perform a rigorous theoretical convergence analysis of the discrete dipole approximation (DDA). We prove that errors in any measured quantity are bounded by a sum of a linear term and a quadratic term in the size of a...

Visualizing the whispering gallery modes in a cylindrical optical microcavity.

Optics letters

Balistreri ML, Klunder DJ, Blom FC, Driessen A, Hoekstra HW, Korterik JP, Kuipers L, van Hulst NF.
PMID: 18079945
Opt Lett. 1999 Dec 15;24(24):1829-31. doi: 10.1364/ol.24.001829.

Whispering gallery modes in cylindrical integrated optics microcavities have, for what is to our knowledge the first time, been mapped with a photon scanning tunneling microscope. Optical images were obtained with a spatial resolution of 50 nm. By combination...

Theory of optical spontaneous emission rates in layered structures.

Physical review. E, Statistical, nonlinear, and soft matter physics

Hoekstra HJ, Elrofai HB.
PMID: 15903808
Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Apr;71(4):046609. doi: 10.1103/PhysRevE.71.046609. Epub 2005 Apr 14.

This paper presents expressions for the optical power and fields radiated by an oscillating dipole in layered structures, with loss or gain, that are easy to evaluate. For structures without loss or gain, it is discussed that the radiated...

Membrane phase transitions are responsible for imbibitional damage in dry pollen.

Proceedings of the National Academy of Sciences of the United States of America

Crowe JH, Hoekstra FA, Crowe LM.
PMID: 16594011
Proc Natl Acad Sci U S A. 1989 Jan;86(2):520-3. doi: 10.1073/pnas.86.2.520.

We have found that the most probable cause of the leakage seen when dry cells or organisms such as seeds, pollen, or yeast cells are plunged into water is a gel to liquid crystalline phase transition in membrane phospholipids...
