This review examines cellulose as a sustainable platform for triboelectric nanogenerators, linking molecular structure, surface chemistry, and material engineering to charge generation, retention, and dissipation. Native, regenerated, and nanocellulose materials, functionalization strategies, scalable manufacturing, and diverse applications are ...

High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

Epiphora: A Structured Diagnostic Approach for the Otolaryngologist
ABSTRACT Introduction Epiphora, or excessive tearing, has historically been predominantly managed by ophthalmologists. However, as there is substantial overlap between ophthalmic and otolaryngologic anatomy and pathology that may contribute to epiphora, patients with this symptom often present to otolaryngologists as well.

Modifications of the fundamental equation of X‐ray stress analysis are proposed that allow correction of the hoop and longitudinal stresses obtained from sin2ψ measurements on samples featuring an inhomogeneous surface topography. The formalism is verified by angle‐ and energy‐dispersive measurements performed on a ferritic steel sample with ...

ABSTRACT With the retirement of 21GW of legacy coal fleet looming, the task to replace Australia's thermal capacity with alternative firmed renewable ‘bulk energy’ solutions is non‐trivial. Indeed, calibrating necessary capital investment in new plant stock with efficient economic outcomes, vis‐à‐vis cost and reliability, represents a fundamental ...

Abstract This article argues that the current debate over defence spending in the United Kingdom is fundamentally flawed. Too much emphasis is being placed on preparing for a form of warfare with Russia that is unlikely to occur. As this article points out, the Russians actually want to avoid a traditional battlefield confrontation with NATO.

Is the rent too high? Land ownership and monopoly power
Abstract Pricing power in real estate markets can reduce housing supply and redevelopment relative to the social optimum. We show how pricing power interacts with popular redevelopment subsidies and zoning regulations. Using building‐level rental income data from NYC, we find that increased concentration is correlated with increased rents.
