Nucleosynthesis of Nickel-56 from Gamma-Ray Burst Accretion Disks

, 2011
We examine the prospects for producing Nickel-56 from black hole accretion disks, by examining a range of steady state disk models. We focus on relatively slowly accreting disks in the range of 0.05 - 1 solar masses per second, as are thought to be ...

Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

Plant, Cell &Environment, EarlyView.
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

δ13C and δ15N Values of Residues Provide Insights Into Identification of the Explosive Source

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Postblast analyses of military and terrorist events will benefit from the capacity to learn more about the explosive materials used in an event. Here stable isotope ratio analyses (δ13C, δ15N) can provide additional information to complement identification of the explosive components.

Spectra of supernovae in the nebular phase

, 2017
When supernovae enter the nebular phase after a few months, they reveal spectral fingerprints of their deep interiors, glowing by radioactivity produced in the explosion.

Metal‐Doped Carbon‐Based Nanomaterials: Photothermal Mechanism Innovation and Precision Therapy Advancement in Antibacterial and Antitumor Applications

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Metal‐doped carbon‐based nanomaterials (M‐CNM) play a strategically significant role in next‐generation precision antibacterial and antitumor therapies, as they integrate synergistic photothermal ablation, catalytic reactive oxygen species (ROS) generation, and multimodal imaging capabilities. However, their clinical translation is hindered by

Atomically Dispersed Cobalt on Ionic Carbon Nitrides for Selective and Efficient Nitrate Electroreduction to Ammonia

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
By exploiting the structural benefits of PHI, we synthesized CoPHI with atomically dispersed cobalt sites at high density. This architecture enables efficient nitrate ion adsorption, promotes water dissociation, and enhances *H generation on the catalyst surface, thereby significantly improving electrochemical nitrate reduction performance.

Portable X‐Ray Fluorescence in the Assessment of Zinc Along Grizzly Bear Hair

X-Ray Spectrometry, Volume 55, Issue 3, Page 473-482, May/June 2026.
ABSTRACT As a biomarker of past uptake of zinc, hair presents an interesting option since its growth can provide a stored record over time. This study investigates the distribution of zinc in hairs gathered from a series of grizzly bears ( Ursus arctos horribilis ).

Partitioning of Major and Trace Elements in a Stand of the Nickel Hyperaccumulator Rinorea cf. bengalensis in Borneo

Ecological Research, Volume 41, Issue 3, May 2026.
Rinorea cf. bengalensis is a tropical nickel hyperaccumulator plant that can be dominant in forests locally. We investigated the partitioning of major and trace elements in a stand of R. cf. bengalensis in Borneo. Hyperaccumulators have a large impact on the cycling of Ni and other elements in their ecosystem. ABSTRACT Rinorea cf.

Emerging Technologies for Biobutanol Production via Syngas Fermentation

GCB Bioenergy, Volume 18, Issue 5, May 2026.
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...
