Selective Targeting of Immune Checkpoints HLA‐G and CD47 Using Novel Dual Signaling Protein DSP216 Promotes Innate Anticancer Immunity

Advanced Science, EarlyView.
The inhibitory immune checkpoints HLA‐G and CD47 are expressed on certain tumor types and inhibit immune cells in the tumor microenvironment. DSP216 binds specifically to cancer cells expressing both HLA‐G and CD47, and blocks their inhibitory signaling.

In‐Operando 4D‐STEM and STEM‐EBIC Imaging of Electric Fields and Charge Carrier Behavior in Biased Silicon p–n Junctions

Advanced Electronic Materials, EarlyView.
This work presents a study of how 4D‐STEM centre of mass measurements and STEM‐EBIC can be used to map the positions, directions, and strengths of electric fields in semiconductor devices. The contrast mechanisms of both techniques are tested and compared with simulations to build a robust analysis of an in situ device in the electron microscope ...

Estimating lightning current moment waveforms from satellite optical measurements [PDF]

Geophysical Research Letters, 2009
From July 2004 to June 2007, the FORMOSAT‐2/ISUAL spectrophotometer and Duke magnetometer observed clear optical and radio signatures of 12 sprite‐producing lightning events. In 10 of these, 777.4‐nm luminosity normalized to a distance of 3000 km was almost linearly correlated with current moment with a scaling factor of ∼0.82 MR/kAkm.

Atomic Scale Ordering of Liquid Water at a Dynamic Pt(111) Interface Under Electrochemical Conditions Imaged by Electron Holography

Advanced Energy Materials, EarlyView.
High resolution electron holography was used to image the projected electric potential of ordered water layers at the interface to a platinum (111) electrode. The observed reorganization of the water layers upon applying external potentials suggests that the electric potential drop of the electric double layer is mainly carried by the polarization ...

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Calculation of Transient Potential Rise on the Wind Turbine Struck by Lightning

The Scientific World Journal, 2014
A circuit model is proposed in this paper for calculating the transient potential rise on the wind turbine struck by lightning. The model integrates the blade, sliding contact site, and tower and grounding system of the wind turbine into an equivalent ...
