Advanced Materials, EarlyView.This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Orthogonal starters in finite abelian groups [PDF]
, 1990 Two problems are considered. First, the conjecture that all odd abelian groups except Z3, Z5, Z9, and Z3+Z3 admit strong starters, is reduced to finding strong starters in five types of groups; the cyclic groups of order 3p, 9p, 3k for k>6, 5 · 3k for k ...

Magnetic-dipole corrections to RK and RK* in the Standard Model and dark photon scenarios [PDF]
, 2020 In this work we evaluate the long-distance QED contributions, induced by the magnetic-dipole corrections to the final charged leptons, on the B meson decay widths B → (K, K*)l+l− and ratios RK,K* = Γ(B → (K, K*)μ+μ−)/Γ(B → (K, K*)e+e−), as well as on ...

Advanced Materials Technologies, EarlyView.A combined experimental and simulation study of light‐responsive liquid crystal elastomer surfaces operating under physiological conditions is reported, demonstrating programmable and highly spatially controlled topography formation through bottom‐side photomask exposure. Our study establishes a foundation for dynamic, light‐responsive biosurfaces with

Some new classes of strong starters [PDF]
, 1975 It has been known for some time that proportionally more strong starters can be constructed for elementary pk-groups where pk ≡ 3 (mod4) than for pk ≡ 1 (mod4) by the method of Mullin and Nemeth.

Advanced Science, EarlyView.This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Role of tensor operators in RK and RK⁎
, 2017 The recent LHCb measurement of RK⁎ in two q2 bins, when combined with the earlier measurement of RK, strongly suggests lepton flavour non-universal new physics in semi-leptonic B meson decays.

Advanced Science, EarlyView.Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Advanced Science, EarlyView.In this research article, Mansoor and coworkers present a novel device that applies controlled mechanical stimuli to cardiomyocytes using pressure‐driven membrane deformation. By exposing cells to physiologically and pathologically relevant loading conditions, the platform reproduces distinct structural, functional and molecular responses associated ...

The Post-Entry Performance of Cohorts of Export Starters in German Manufacturing Industries [PDF]
This paper investigates four cohorts of firms from German manufacturing industries that started to export in the years between 1998 and 2002 and follows them over the five years after the start.
