Non-Markovianity induced by a single-photon wave packet in a one-dimensional waveguide.

Optics letters

Valente D, Arruda MF, Werlang T.
PMID: 27367118
Opt Lett. 2016 Jul 01;41(13):3126-9. doi: 10.1364/OL.41.003126.

The concept of non-Markovianity (NM) in quantum dynamics is still an open debate. Understanding how to generate and measure NM in specific models may aid in this quest. In quantum optics, an engineered electromagnetic environment coupled to a single...

Gold nanoclusters with bright near-infrared photoluminescence.

Nanoscale

Pramanik G, Humpolickova J, Valenta J, Kundu P, Bals S, Bour P, Dracinsky M, Cigler P.
PMID: 29412211
Nanoscale. 2018 Feb 22;10(8):3792-3798. doi: 10.1039/c7nr06050e.

The increase in nonradiative pathways with decreasing emission energy reduces the luminescence quantum yield (QY) of near-infrared photoluminescent (NIR PL) metal nanoclusters. Efficient surface ligand chemistry can significantly improve the luminescence QY of NIR PL metal nanoclusters. In contrast...

Boron-Incorporating Silicon Nanocrystals Embedded in SiO.

Scientific reports

Hiller D, López-Vidrier J, Gutsch S, Zacharias M, Wahl M, Bock W, Brodyanski A, Kopnarski M, Nomoto K, Valenta J, König D.
PMID: 28827565
Sci Rep. 2017 Aug 21;7(1):8337. doi: 10.1038/s41598-017-08814-0.

Boron (B) doping of silicon nanocrystals requires the incorporation of a B-atom on a lattice site of the quantum dot and its ionization at room temperature. In case of successful B-doping the majority carriers (holes) should quench the photoluminescence...

Probing silicon quantum dots by single-dot techniques.

Nanotechnology

Sychugov I, Valenta J, Linnros J.
PMID: 27980232
Nanotechnology. 2017 Feb 17;28(7):072002. doi: 10.1088/1361-6528/aa542b. Epub 2016 Dec 16.

Silicon nanocrystals represent an important class of non-toxic, heavy-metal free quantum dots, where the high natural abundance of silicon is an additional advantage. Successful development in mass-fabrication, starting from porous silicon to recent advances in chemical and plasma synthesis,...

Hydration Status: Influence of Exercise and Diet Quality.

American journal of lifestyle medicine

San Mauro Martín I, Garicano Vilar E, Romo Orozco DA, Mendive Dubourdieu P, Paredes Barato V, Rincón Barrado M, Valente A, Bentancor F, Morales Hurtado AD, Garagarza C.
PMID: 31285725
Am J Lifestyle Med. 2017 Jun 06;13(4):414-423. doi: 10.1177/1559827617711906. eCollection 2019.

Physical activity, adherence to a healthy diet, and healthy beverage pattern are considered essential components of a healthy lifestyle. We aimed to evaluate the associations between physical exercise, diet quality, and total fluid intake, along with fluid recommendations compliance...

Power-dependent photoluminescence decay kinetics of silicon nanocrystals under continuous and pulsed excitation.

Faraday discussions

Greben M, Valenta J.
PMID: 32108199
Faraday Discuss. 2020 Jun 19;222:274-293. doi: 10.1039/c9fd00100j.

Power-dependent photoluminescence (PL) decay kinetics of silicon nanocrystals (Si NCs) in solid and liquid samples were studied under cw and pulsed excitation. The lifetime distribution and, consequently the measured PL kinetics are shown to depend on the excitation pulse...

Late Miocene megalake regressions in Eurasia.

Scientific reports

Palcu DV, Patina IS, Șandric I, Lazarev S, Vasiliev I, Stoica M, Krijgsman W.
PMID: 34075146
Sci Rep. 2021 Jun 01;11(1):11471. doi: 10.1038/s41598-021-91001-z.

The largest megalake in the geological record formed in Eurasia during the late Miocene, when the epicontinental Paratethys Sea became tectonically-trapped and disconnected from the global ocean. The megalake was characterized by several episodes of hydrological instability and partial...

Two-step light conversion with quantum dots inside non-linear crystals.

The Journal of chemical physics

Vorontsov D, Okrepka G, Khalavka Y, Valenta J.
PMID: 33003710
J Chem Phys. 2020 Sep 28;153(12):121105. doi: 10.1063/5.0022785.

Up-conversion of infrared (IR) to visible light is demonstrated via an unconventional two-step process combining second harmonic generation with photoluminescence. This is achieved in a composite material formed by single crystals of KH

Effect of the application of an edible film with turmeric (C.

Food science & nutrition

Bojorges H, Ríos-Corripio MA, Hernández-Cázares AS, Hidalgo-Contreras JV, Contreras-Oliva A.

Food Sci Nutr. 2020 Jul 11;8(8):4308-4319. doi: 10.1002/fsn3.1728. eCollection 2020 Aug.

The aim of this study was to develop an edible alginate-based film produced with turmeric (EFT), as an active compound, and evaluate its antioxidant capacity for application in fresh pork loin, beef loin, and chicken breast. The EFT was...

Room-Temperature Defect Qubits in Ultrasmall Nanocrystals.

The journal of physical chemistry letters

Beke D, Valenta J, Károlyházy G, Lenk S, Czigány Z, Márkus BG, Kamarás K, Simon F, Gali A.
PMID: 32040330

There is an urgent quest for room-temperature qubits in nanometer-sized, ultrasmall nanocrystals for quantum biosensing, hyperpolarization of biomolecules, and quantum information processing. Thus far, the preparation of such qubits at the nanoscale has remained futile. Here, we present a...
