Carbon‐based materials from renewable sources: Challenges and perspectives with a focus on green coconut

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract This article presents a comprehensive examination of agricultural production, biomass generation, and its transformation into biochar, with a particular emphasis on green coconut waste as a primary resource. It underscores the link between agriculture and substantial biomass output, shedding light on the ecological issues associated with solid

The WFCAM transit survey and cool white dwarfs

EPJ Web of Conferences, 2013
We present results from our search for cool white dwarfs in the WTS (WFCAM Transit Survey). Repeat observations starting in 2007 allowed to produce deep stacked images in J and measure proper motions.

Evaluation of Brain Microstructural Alterations in Preschool Autism Spectrum Disorder: A Voxel‐Wise Multimodal MRI Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Autism Spectrum Disorder (ASD) presents with early neurodevelopmental alterations in preschool children, yet comprehensive characterization using multimodal quantitative MRI remains limited in this age group. Purpose To investigate voxel‐wise brain microstructural differences in preschool ASD through integrated analysis of cerebral ...

A Test of Spectroscopic Age Estimates of White Dwarfs Using Wide WD+WD Binaries

The Astrophysical Journal
White dwarf stars have been used for decades as precise and accurate age indicators. This work presents a test of the reliability of white dwarf total ages when spectroscopic observations are available. We conduct follow-up spectroscopy of 148 individual

A survey of pulsating DA and DB white dwarfs Observations with the Whole Earth Telescope

EPJ Web of Conferences, 2017
White dwarfs represent the end point of stellar evolution for the majority of stars. As such, they are excellent astrophysical laboratories. They are structurally simple, with electron degenerate cores surrounded by thin surface layers of helium and/or ...

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

Journal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

An All-sky Survey of White Dwarf Merger Remnants: Far-Ultraviolet Is the Key

The Astrophysical Journal
The majority of merging white dwarfs leave behind a white dwarf remnant. Hot/warm DQ white dwarfs with carbon-rich atmospheres have high masses and unusual kinematics. All evidence points to a merger origin.

Experiences of Drainage and Associated Impacts: A Qualitative Study Among Patients With Hidradenitis Suppurativa

JEADV Clinical Practice, EarlyView.
This study provides an in‐depth account of patients' experiences of drainage as a symptom of hidradenitis suppurativa. The HIDE Scale© facilitates incorporation of these insights into clinical practice, supporting person‐centred approaches that enhance clinical assessment, reduce stigma, and strengthen patient–clinician communication.
