Sums with convolutions of Dirichlet characters to cube-free modulus [PDF]
Proceedings of the American Mathematical Society, 2011 We find estimates for short sums of the form ∑ n m ⩽ X χ 1 ( n ) χ 2 ( m ) \sum _{nm \leqslant X} \chi _1 (n) \chi _2 (m) , where χ 1

Advanced Engineering Materials, EarlyView.We develop a one‐step spray coating approach to coat the fluorinated graphene (FG) nanosheet onto the N95 respirators. The spray‐coated superhydrophobic N95 respirators can effectively repel respiratory droplets off instantaneously and prevent SARS‐CoV‐2 virus accumulation on the surface.

Scalable Fabrication of Height‐Variable Microstructures with a Revised Wetting Model
Advanced Engineering Materials, EarlyView.Height‐variable microstructures are fabricated using a scalable CO2 laser machining approach, enabling precise control of wettability through structural gradients. Classical wetting models fail to capture height‐induced effects, necessitating a revised theoretical framework.

Advanced Engineering Materials, EarlyView.Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Free Convolution and the Random Sum of Matrices
Publications of the Research Institute for Mathematical Sciences, 1993 We show that the spectral measure of the sum of two selfadjoint matrices is 'almost surely' given by the free convolution (in the sense of Voiculescu) of the spectral measures of the two matrices if their size tends to infinity.
