PMID: 8979867
Contemp Educ Psychol. 1996 Oct;21(4):305-24. doi: 10.1006/ceps.1996.0024.

Two hundred twenty-four undergraduate students wrote about one-half of an inning of a baseball game and about one-half of a soccer game, counterbalanced, for 20 min each. Students then completed two six-item interest inventories-one each on the topics of...

Nanosecond Spin Coherence Time of Nonradiative Excitons in GaAs/AlGaAs Quantum Wells.

Physical review letters

Trifonov AV, Khramtsov ES, Kavokin KV, Ignatiev IV, Kavokin AV, Efimov YP, Eliseev SA, Shapochkin PY, Bayer M.
PMID: 31050466
Phys Rev Lett. 2019 Apr 12;122(14):147401. doi: 10.1103/PhysRevLett.122.147401.

We report on the experimental evidence for a nanosecond timescale spin memory based on nonradiative excitons with large in-plane wave vector. The effect manifests itself in magnetic-field-induced oscillations of the energy of the optically active (radiative) excitons. The oscillations...

Modified Desolvation Method Enables Simple One-Step Synthesis of Gelatin Nanoparticles from Different Gelatin Types with Any Bloom Values.

Pharmaceutics. 2021 Sep 22;13(10). doi: 10.3390/pharmaceutics13101537.

Gelatin nanoparticles found numerous applications in drug delivery, bioimaging, immunotherapy, and vaccine development as well as in biotechnology and food science. Synthesis of gelatin nanoparticles is usually made by a two-step desolvation method, which, despite providing stable and homogeneous...

Fluorescence recovery under decaying photobleaching irradiation: concept and experiment.

Journal of fluorescence

Glazachev YI, Khramtsov VV.
PMID: 17004134
J Fluoresc. 2006 Nov;16(6):773-81. doi: 10.1007/s10895-006-0130-8. Epub 2006 Sep 27.

A novel modification of photobleaching method for measurement of lateral diffusion is developed. In this approach fluorescence recovery kinetics is measured under decaying photobleaching irradiation, termed as fluorescence recovery under decaying photobleaching (FRDP). The time evolution of fluorescence intensity...

Bright Silicon Carbide Single-Photon Emitting Diodes at Low Temperatures: Toward Quantum Photonics Applications.

Nanomaterials (Basel, Switzerland)

Khramtsov IA, Fedyanin DY.
PMID: 34947525
Nanomaterials (Basel). 2021 Nov 24;11(12). doi: 10.3390/nano11123177.

Color centers in silicon carbide have recently emerged as one of the most promising emitters for bright single-photon emitting diodes (SPEDs). It has been shown that, at room temperature, they can emit more than 10

Interaction of Graphene Oxide Modified with Linear and Branched PEG with Monocytes Isolated from Human Blood.

Nanomaterials (Basel, Switzerland)

Khramtsov P, Bochkova M, Timganova V, Nechaev A, Uzhviyuk S, Shardina K, Maslennikova I, Rayev M, Zamorina S.
PMID: 35010076
Nanomaterials (Basel). 2021 Dec 30;12(1). doi: 10.3390/nano12010126.

Multiple graphene-based therapeutics have recently been developed, however potential risks related to the interaction between nanomaterials and immune cells are still poorly understood. Therefore, studying the impact of graphene oxide on various populations of immune cells is of importance....
