Molecular Bridges for 2D Nanomaterials

open access: yesAdvanced Functional Materials, EarlyView.
Molecular cross‐linking provides a versatile strategy to engineer interfaces in 2D materials. By tuning the linker backbone, binding mode, and interflake spacing, molecular bridges can regulate charge transport, mechanical integrity, chemical functionality, and processing.

Design of a Printed Dipole Antenna Array for a Passive Radar System

open access: yesInternational Journal of Antennas and Propagation, 2013
Passive radar (or Passive Coherent Localisation) is an advancing technology for covert operation. The signal transmitted from sources of opportunity such as radio or TV stations is used as illumination for a certain area of interest.

Electrospun Core–Shell Bioadhesive Nanofiber Sheets Enable Durable Pulmonary Air Leak Sealing Under Wet and Dynamic Conditions

open access: yesAdvanced Healthcare Materials, EarlyView.
A core–shell electrospun nanofiber sheet provides strong adhesion and durable sealing on the wet and dynamic lung surface. The engineered fibrous architecture maintains airtight integrity and offers a potential alternative to fibrin sealants for pulmonary air leak management in thoracic surgery.

Radar matched filtering using the fractional fourier transform [PDF]

open access: yes, 2010
-A matched filter is the optimal linear filter for maximizing the signal to noise ratio (SNR) in the presence of additive noise. Matched filters are commonly used in radar systems where the transmitted signal is known and may be used as a replica to be ...

Lattice Strain and Built‐In Field Synergistically Boost Urea Oxidation via Dynamic NiOOH Mediation at Multiphase Heterointerfaces

open access: yesAdvanced Materials, EarlyView.
A sulfur‐doped lignin‐derived carbon‐coated Ni‐NiO‐MoO2 nanorod array was synthesized, exhibiting enhanced UOR performance ‐ due to lattice‐strain and built‐in electric field effects by multiphase heterogeneous interface in Ni‐NiO‐MoO2@SC, excellent corrosion resistance, mass‐transport ability, and long‐term stability (500 mA cm−2 at 1.53 V for 500 h ...

How “Green” is Your Functional Material? Assessing Environmental Impacts of Multi‐Step Synthetic Protocols in Material Sciences at Various Technology Levels

open access: yesAdvanced Materials, EarlyView.
Environmental Synthesis Radar (ESR) evaluates the environmental impact of (early‐stage) multi‐step chemical syntheses, providing a holistic view by using 18 midpoint impact categories. Unlike conventional life‐cycle assessment (LCA) approaches, ESR reveals three complementary metrics: overall impact Vtotal, environmental hotspots VEF, and critical ...
