Experimental Measurement of Pre-Melting and Melting of Thorium Dioxide [PDF]
Thorium dioxide samples have been submitted to homogeneous four-beam laser pulses in an autoclave filled with different gases. Phase transitions were analysed through the produced thermal arrest stages, which were detection by a precise multichannel ...

The Impact of Urban Land Use Patterns on the Synergy of Pollution Reduction and Carbon Mitigation
ABSTRACT To tackle global climate change and fulfill China's dual carbon objectives, the coordinated abatement of pollution and carbon emissions has emerged as a pivotal focus for sustainable urban development. Land use patterns and pollutant emissions are deeply connected within cities, making them a crucial lever for advancing synergistic pollution ...

ABSTRACT Human activities have intensified eco‐environmental problems, challenging harmonious human‐nature interactions. However, existing integrated protection and restoration (IPR) zoning approaches for mountains, rivers, forests, farmlands, lakes, and grasslands (MRFFLG) focus on a single scale and fail to incorporate the ecological network (EN) and

Responsive Phase Gradient Metasurface for Laser Stealth and Dynamic Thermal Camouflage
The graphical abstract depicts a phase‐gradient metasurface enabling directional scattering and emissivity‐controlled thermal radiation. The engineered phase profile redistributes the reflected optical momentum, suppressing specular reflection and generating non‐specular scattering.

Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems
Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...

Estimation of Thorium Deposited in Thorotrast Patients by CT Scanner in Comparison with Whole Body Counter [PDF]
The deposits of thorium dioxide in Thorotrast patients are observed in the reticulo-endotherial system, such as liver and spleen. The amounts of deposits in patients can be estimated by a whole body counter, but hospitals which have the apparatus are few.

ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Urban Housing Markets and Sustainability Risk: Empirical Evidence From South African Cities
ABSTRACT Despite the global shift toward sustainability and rising expectations for socially and environmentally responsible housing, evidence from South Africa's urban markets remains limited and underexplored. This study examines how sustainability‐related vulnerabilities shape downside housing risk across 60 cities between 2002 and 2021.

This publication describes how R. B. Woodward and Roald Hoffmann crafted their masterpiece publications. Illustrations include Woodward's first draft of the famous “Violations There are none. Nor can violations be expected of so fundamental a principle of maximum bonding.” Original but discarded text shows the stepwise paths toward the W‐H masterpieces.

Do Financialization and Innovation Enhance Environmental Sustainability in Sub‐Saharan Africa?
ABSTRACT This study addresses the perception of Sub‐Saharan Africa (SSA) as a region with limited financial capabilities and technological advancement to enhance environmental sustainability. Conducted across 24 SSA countries from 2000 to 2021, the research employs instrumental IV and panel quantile regressions.
