Visualisation and interpretation of PolSAR data based on polarimetric coherence

open access: yesThe Journal of Engineering, 2019
Polarimetric coherence strongly relates to the target scattering characteristics. Coherences of different second-order statistics show different advantages in target discrimination in specific correspondence to physical scattering mechanism.

Compliant hydrogel cuff coating with real‐time pressure monitoring and antibiofilm capabilities for ventilator‐associated pneumonia prophylaxis

open access: yesBMEMat, EarlyView.
A soft‐compliant hydrogel cuff coating combines real‐time pressure monitoring with intrinsic antibacterial activity for prophylaxis of ventilator‐associated pneumonia. A flexible pressure‐sensing patch is embedded in the coating to enable wireless dynamic monitoring of endotracheal cuff pressure through Bluetooth.

Circular Transitions in Healthcare Waste Management in Vietnam: An Institutional Perspective

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Healthcare waste management (HCWM) is a growing environmental and public health concern. This study explores how the institutional pressures that shape HCWM practices evolve toward circularity through coercive, normative, and mimetic isomorphisms and how these mechanisms influence organisational behaviour in Vietnam, a complex, highly ...

Controlled Formation and Unusual Reactivity of Cyanohexatriyne (HC7N), a Synthetically Challenging Interstellar Cyanopolyyne

open access: yesChemistry – A European Journal, EarlyView.
First controlled formation of cyanohexatriyne (HC7N) is achieved using a cobalt–alkyne masking strategy that overcomes the intrinsic instability of nitrile‐substituted polyynes. The approach enables spectroscopic validation of HC7N and reveals its pronounced electrophilicity through a selective conjugate addition with diethylamine.

Mild C─F Activation of Azido(per)Fluoroalkanes

open access: yesChemistry – A European Journal, EarlyView.
Mild and selective activation of C(sp3)–F bonds in azido(per)fluoroalkanes using thiolates was developed, leading to novel functionalized azides. The reaction is initiated by nucleophilic attack of the sulfur atom to the terminal nitrogen of the azido group, followed by fluoride ion elimination.

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

open access: yesChemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Passive-microwave remote sensing of snow [PDF]

open access: yesAnnals of Glaciology, 1993
The radiative-transfer theory and the Rayleigh scattering model were used to obtain the microwave brightness temperatures from dry snowpacks on the ground, which was modelled by a scattering dielectric layer and an underlying homogeneous half-space.
