Detecting and attributing climate change effects on vegetation: Australia as a test case

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Analytical model for fast-shock ignition

AIP Advances, 2014
A model and its improvements are introduced for a recently proposed approach to inertial confinement fusion, called fast-shock ignition (FSI). The analysis is based upon the gain models of fast ignition, shock ignition and considerations for the fast ...

Laser ignition of dust clouds [PDF]

Journal de Physique IV (Proceedings), 2002
In a previous paper [1], the possibility of igniting a combustible dust-air mixtures by a light beam in contact with a substrate made of an inert matter and heated by a light beam was investigated. The objective of the present work is to produce more data on the subject.

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Advances in the national inertial fusion program of China

EPJ Web of Conferences, 2013
The planned inertial confinement fusion (ICF) ignition in China in around 2020 is to be accomplished in three steps. The first is carrying out target physics experiments in the existing laser facilities SG-II, SG-IIIP and SG-IIU (operating in 2012) of ...

A Multifunctional Bioactive Nanoscale Coating Deposited by Atmospheric Pressure Plasma Polymerization of Peppermint Essential Oil

Small, EarlyView.
Atmospheric plasma polymerization transforms peppermint essential oil into ultrathin, substrate‐independent bioactive coatings with antioxidant, contact‐active antibacterial, and immunomodulatory functions. The coating disrupts Gram‐negative pathogens, potentiates prophylactic antibiotics, suppresses pro‐inflammatory signaling, and promotes M2 ...

Vapor‐Phase Synthesis of Potassium‐Doped Polymeric Carbon Nitride Photocatalytic Panels

Small, EarlyView.
Potassium‐doped polymeric carbon nitride (CN) panels are synthesized via a vapor‐phase condensation method over KCl‐coated substrates. Temperature‐controlled growth and K+ incorporation induce cyano‐group defects, enhance light absorption, and improve charge dynamics, leading to superior photocatalytic H2O2 production.

Hydrodynamic Implosion Simulation Including Relativistic Effects on Petawatt-Class Pulse Heating

, 2003
A spherically symmetric fluid code that includes the relativistic effects of hot electrons has been newly developed. In the present simulations, I attempt to implode a target shell of laser fusion using a nanosecond pulse; then, an additional heating ...
