Does 1,8-diiodooctane affect the aggregation state of PC71BM in solution? [PDF]

open access: yesRoyal Society Open Science, 2018
1,8-Diiodooctane (DIO) is an additive used in the processing of organic photovoltaics and has previously been reported, on the basis of small-angle X-ray scattering (SAXS) measurements, to deflocculate nano-aggregates of [6,6]-phenyl-C71-butyric acid ...

Bone mineral properties and 3D orientation of human lamellar bone around cement lines and the Haversian system

open access: yesIUCrJ, 2023
Bone is a complex, biological tissue made up primarily of collagen fibrils and biomineral nanoparticles. The importance of hierarchical organization in bone was realized early on, but the actual interplay between structural features and the properties on

TSAX is Trending [PDF]

open access: yesLecture Notes in Computer Science 12743, Springer 2021, 2021
Time series mining is an important branch of data mining, as time series data is ubiquitous and has many applications in several domains. The main task in time series mining is classification. Time series representation methods play an important role in time series classification and other time series mining tasks.

Size and structure of hexanuclear plutonium oxo-hydroxo clusters in aqueous solution from synchrotron analysis

open access: yesJournal of Synchrotron Radiation, 2022
The size and shape of a water-soluble hexanuclear plutonium cluster were probed by combining synchrotron small-angle X-ray scattering (SAXS) and extended X-ray absorption fine structure (EXAFS).

Conformational ensembles of an intrinsically disordered protein consistent with NMR, SAXS and single-molecule FRET.

open access: yesJournal of the American Chemical Society, 2020
Intrinsically disordered proteins (IDPs) have fluctuating heterogeneous conformations, which makes structural characterization challenging, but of great interest, since their conformational ensembles are the link between their sequences and functions. An

Polyethylene oxide matrix tablet swelling evolution: The impact of molecular mass and tablet composition

open access: yesActa Pharmaceutica, 2021
This article describes the designing of matrix tablets composed of polyethylene oxides (PEOs) with relative molecular masses of 1 × 106, 2 × 106, and 4 × 106. Percolation thresholds were determined for all of the selected PEO formulations (18, 16, and 12

Direct measurement of Stokes–Einstein diffusion of Cowpea mosaic virus with 19 µs-resolved XPCS

open access: yesJournal of Synchrotron Radiation, 2022
Brownian motion of Cowpea mosaic virus (CPMV) in water was measured using small-angle X-ray photon correlation spectroscopy (SA-XPCS) at 19.2 µs time resolution. It was found that the decorrelation time τ(Q) = 1/DQ2 up to Q = 0.091 nm−1. The hydrodynamic

Modifying the Symbolic Aggregate Approximation Method to Capture Segment Trend Information [PDF]

open access: yesLecture Notes in Computer Science 12256, Springer 2020, 2020
The Symbolic Aggregate approXimation (SAX) is a very popular symbolic dimensionality reduction technique of time series data, as it has several advantages over other dimensionality reduction techniques. One of its major advantages is its efficiency, as it uses precomputed distances.

Structural insights into the substrate-binding proteins Mce1A and Mce4A from Mycobacterium tuberculosis

open access: yesIUCrJ, 2021
Mycobacterium tuberculosis (Mtb), which is responsible for more than a million deaths annually, uses lipids as the source of carbon and energy for its survival in the latent phase of infection.
