Kafshgari MH, Cavallaro A, Delalat B, Harding FJ, McInnes SJ, Mäkilä E, Salonen J, Vasilev K, Voelcker NH.
PMID: 25114633
Nanoscale Res Lett. 2014 Jul 04;9(1):333. doi: 10.1186/1556-276X-9-333. eCollection 2014.

In this study, the ability of porous silicon nanoparticles (PSi NPs) to entrap and deliver nitric oxide (NO) as an effective antibacterial agent is tested against different Gram-positive and Gram-negative bacteria. NO was entrapped inside PSi NPs functionalized by...

Contact formation in random networks of elongated objects.

Physical review letters

Ekman A, Miettinen A, Tallinen T, Timonen J.
PMID: 25615387
Phys Rev Lett. 2014 Dec 31;113(26):268001. doi: 10.1103/PhysRevLett.113.268001. Epub 2014 Dec 24.

The effect of steric hindrance is an important aspect of granular packings as it gives rise to, e.g., limitations on the densities of ordered and disordered packings, both of which are essentially defined by the geometry of the constituents....

Thermally Carbonized Porous Silicon and Its Recent Applications.

Advanced materials (Deerfield Beach, Fla.)

Salonen J, Mäkilä E.
PMID: 29484727
Adv Mater. 2018 Jun;30(24):e1703819. doi: 10.1002/adma.201703819. Epub 2018 Feb 27.

Recent progress in research on thermally carbonized porous silicon (TCPSi) and its applications is reported. Despite a slow start, thermal carbonization has now started to gain interest mainly due to new emerging areas for applications. These new areas, such...

Imaging connected porosity of crystalline rock by contrast agent-aided X-ray microtomography and scanning electron microscopy.

Journal of microscopy

Kuva J, Sammaljärvi J, Parkkonen J, Siitari-Kauppi M, Lehtonen M, Turpeinen T, Timonen J, Voutilainen M.
PMID: 29071713
J Microsc. 2018 Apr;270(1):98-109. doi: 10.1111/jmi.12661. Epub 2017 Oct 26.

We set out to study connected porosity of crystalline rock using X-ray microtomography and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) with caesium chloride as a contrast agent. Caesium is an important radionuclide regarding the final deposition...

Enhanced Photoluminescence in Acetylene-Treated ZnO Nanorods.

Nanoscale research letters

Jäppinen L, Jalkanen T, Sieber B, Addad A, Heinonen M, Kukk E, Radevici I, Paturi P, Peurla M, Shahbazi MA, Santos HA, Boukherroub R, Santos H, Lastusaari M, Salonen J.
PMID: 27644239
Nanoscale Res Lett. 2016 Dec;11(1):413. doi: 10.1186/s11671-016-1627-y. Epub 2016 Sep 20.

Zinc oxide (ZnO) nanorods were manufactured using the aqueous chemical growth (ACG) method, and the effect of thermal acetylene treatment on their morphology, chemical composition, and optical properties was investigated. Changes in the elemental content of the treated rods...

Integrated clinical, whole-genome, and transcriptome analysis of multisampled lethal metastatic prostate cancer.

Cold Spring Harbor molecular case studies

Bova GS, Kallio HM, Annala M, Kivinummi K, Högnäs G, Häyrynen S, Rantapero T, Kivinen V, Isaacs WB, Tolonen T, Nykter M, Visakorpi T.
PMID: 27148588
Cold Spring Harb Mol Case Stud. 2016 May;2(3):a000752. doi: 10.1101/mcs.a000752.

We report the first combined analysis of whole-genome sequence, detailed clinical history, and transcriptome sequence of multiple prostate cancer metastases in a single patient (A21). Whole-genome and transcriptome sequence was obtained from nine anatomically separate metastases, and targeted DNA...

Universality in fragmentation.

Physical review letters

Astrom JA, Holian BL, Timonen J.
PMID: 11019012
Phys Rev Lett. 2000 Apr 03;84(14):3061-4. doi: 10.1103/PhysRevLett.84.3061.

Fragmentation of a two-dimensional brittle solid by impact and "explosion," and a fluid by "explosion" are all shown to become critical. The critical points appear at a nonzero impact velocity, and at infinite explosion duration, respectively. Within the critical...

Fracture mechanics of snow avalanches.

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

Aström JA, Timonen J.
PMID: 11461247
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Jul;64(1):011305. doi: 10.1103/PhysRevE.64.011305. Epub 2001 Jun 22.

Dense snow avalanches are analyzed by modeling the snow slab as an elastic and brittle plate, attached by static friction to the underlying ground. The grade of heterogeneity in the local fracture (slip) thresholds, and the ratio of the...

Quantum dynamics of strongly interacting boson systems: atomic beam splitters and coupled Bose-Einstein condensates.

Physical review letters

Bogoliubov NM, Izergin AG, Kitanine NA, Pronko AG, Timonen J.
PMID: 11384254

An effective boson Hamiltonian applicable to atomic beam splitters, coupled Bose-Einstein condensates, and optical lattices can be made exactly solvable by including all n-body interactions. The model can include an arbitrary number of boson components. In the strong interaction...

Clustering and viscosity in a shear flow of a particulate suspension.
