Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Fast electron beam guiding for effective core heating

EPJ Web of Conferences, 2013
In cone-guiding fast ignition, the guiding of fast electron beam with significantly large beam divergence is one of the most important issues for achieving efficient core heating.

Dark Heritage Prospection ‐ Mapping the Treblinka II Extermination Camp Using a Magnetometer Survey and Integrated Archival Sources

Archaeological Prospection, EarlyView.
ABSTRACT The history of Nazi German extermination camps has, until recently, relied primarily on eyewitness testimony. Very few official documents detailing the facilities survived the war due to the special operation ‘Sonderaktion 1005’, dedicated to hiding their existence and extent.

Numerical analysis of misfire in an automotive lean-burn direct-injection spark-ignition engine

Case Studies in Thermal Engineering
Charge dilution strategies, such as exhaust gas recirculation and lean-burn operation, enhance internal combustion engine (ICE) efficiency and reduce NOx emissions.

Operationalizing BioSSbD: A safe‐and‐sustainable‐by‐design framework for biorefineries

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biorefineries are central to the transition toward a circular bioeconomy; however, their increasing scale and technological heterogeneity, and the integration of biological, chemical, and thermochemical processes introduce complex challenges related to safety, sustainability, and operational reliability. Existing Safe‐and‐Sustainable‐by‐Design

Design of high-gain laser fusion with heatwave-driven fast ignition scheme for inertial fusion energy

Nuclear Fusion
We design a high-gain laser fusion employing a fast ignition scheme for inertial fusion energy with a total laser energy less than 1 megajoule. A solid-sphere target which is robust to hydro instabilities is utilized instead of a fragile shell target ...

Biogas production from Opuntia stricta Haw.: microbial diversity and solid load influence on sludge recycle systems

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...

Effect of nonuniform density structure on burn-up ratio of multi-shock-compressed DT fuel in fast ignition

Nuclear Fusion
The burn characteristics of multi-shock-compressed DT fuel under fast ignition conditions are investigated using two-dimensional burn simulations. In solid-sphere implosions, high fuel areal density can be achieved through multi-shock compression with ...

Cylindrical targets for the fast igniter scheme

Plasma Physics and Controlled Fusion, 1996
Using a two-dimensional hydrocode, the collapse of the mid-section of a cylindrical shell target is investigated. The suitability of the resulting compressed plasma for the `hole boring' and `ignition' stages of the fast igniter scheme for inertial confinement fusion is considered.

Creating space(s) for learning in prison: Developing an andragogical framework

British Educational Research Journal, EarlyView.
Abstract Learning in prison is too often excluded from wider discussions of educational experiences, processes and impact. This paper proposes, for the first time, an iterative andragogical framework to conceptualise learning spaces within prison contexts.
