Big whorls carry little whorls [PDF]

open access: yes
The aim of the research was to explore the space-time structure of homogeneous turbulence by computing and then interpreting the two-point spectra and correlations of the velocity and pressure fields.

Taxonomy Of Thermopsis (Fabaceae) In North-America [PDF]

open access: yes, 1994
Comprehensive reevaluation of both herbarium specimens and field observations of the North American Thermopsis leads to our recognition of 10 species. Three species occur in the southern Appalachians: T. villosa, T. mollis, and T. fraxinifolia. The Rocky

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

open access: yesAdvanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

An Overview of Fingerprint Patterns among Students of Gandaki Medical College, Pokhara, Nepal

open access: yesJournal of Gandaki Medical College, 2019
Introduction: Fingerprint system of positive identification is based on the principle that the arrangement and distribution of fingerprint re­mains constant and persists throughout life and that the patterns of no two hands resemble each other ...

Non-autonomy of AGAMOUS function in flower development: use of a Cre/loxP method for mosaic analysis in Arabidopsis [PDF]

open access: yes, 1998
Angiosperms use a multi-layered meristem (typically L1, L2 and L3) to produce primordia that then develop into plant organs, A number of experiments show that communication between the cell layers is important for normal development.

Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

open access: yesAdvanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Non Thermal‐Driven Photocatalytic Ammonia Decomposition at Near‐Room Temperature on a Plasmonic Nanocone Array

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic photocatalytic ammonia decomposition occurs at near‐room temperature on a plasmonic Au nanocone array under visible light illumination. The nanostructure efficiently harnesses plasmonic modes, leading to increased reaction rates upon plasmon decay.

Two New Species of Calcareous Algae (Dasycladaceae) from the Upper Dogger of Southern Dalmatia (Croatia)

open access: yesGeologia Croatica, 2010
Two new species of calcareous algae (Dasycladaceae) are described.One - Salpingoporella croatica n. sp. -is characterized by a clyindricalskeleton and undivided, phloiophorous to partly vesiculiferousrarnifications, arranged in whorls. The other species-
