Tunable Terahertz Generation in Dispersion‐Engineered ZnTe Waveguides
Laser &Photonics Reviews, EarlyView.A dispersion‐engineered Zinc Telluride (ZnTe) slab waveguide platform enables tunable and efficient guided‐wave terahertz (THz) generation through modal phase matching. By tailoring the optical and THz modal dispersion, coherent THz emission is achieved across 0.1–3 THz.

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To improve the accuracy of diffusion‐weighted powder average signals for diffusion encoding with arbitrary b‐tensors. Methods We identify an intrinsic dihedral (D2$$ {D}_2 $$) symmetry of diffusion signals for arbitrary diffusion encoding, which defines their natural signal space (a quotient of 3D rotations).

Curating landscapes to encourage care for biodiversity through arts and citizen science
People and Nature, EarlyView.Abstract This study investigates how combining Citizen Science and Art workshops within curated wildflower meadows can generate repeated, positive experiences with nature, and foster a sense of care for it. The project aimed to increase awareness, encourage responsibility, and develop competencies related to urban nature.

Progress in Photovoltaics: Research and Applications, EarlyView.Front contact selection governs interfacial stability in CdTe‐based (Cd(Se,Te)) solar cells on ultra‐thin space‐qualified cover glass. Optimized TCO/emitter combinations suppress interdiffusion and deliver up to 16.2% AM0 efficiency with high specific power, demonstrating strong potential for lightweight space photovoltaics.

Wide angle search for extrasolar planets by the transit method [PDF]
, 2008 The transit method is considered to be one of the most promising for discovering extrasolar planets. However, the method requires photometric precision of better than ∼ 1%.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Pingos are large mounds with cores formed of intrusive ice that form in periglacial landscapes. These ice structures can form in regions of discontinuous permafrost, commonly as hydraulic or open‐system pingos, or in locations of continuous permafrost, commonly as hydrostatic or closed‐system pingos.
