B fields in OB stars (BOB): FORS2 spectropolarimetric follow-up of the two rare rigidly rotating magnetosphere stars HD23478 and HD345439 [PDF]
, 2015 Massive B-type stars with strong magnetic fields and fast rotation are very rare and provide a mystery for theories of both star formation and magnetic field evolution. Only two such stars, called sigma Ori E analogs, were previously known.

Advanced Functional Materials, EarlyView.Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

Homogenous FACsPbI3 Perovskite Solar Cells Enabled by a Seed‐Facilitated Cation Exchange Strategy
Advanced Functional Materials, EarlyView.A novel seed‐facilitated cation exchange strategy is designed for homogenous FACsPbI3 perovskites using the biomass‐derived solvent γ‐valerolactone. Pre‐deposited 0D Cs4PbI6 seeds induce rapid nucleation and efficient cation exchange, producing a uniform FA–Cs distribution and significantly reducing defect density, enabling high‐performance and stable ...

Transfer Length of Strands in Prestressed Concrete Piles [PDF]
, 2002 A top bar effect has been identified in prestressed concrete piles. The effect that this top bar effect has on the development of the prestressing strand is investigated. Strand transfer length is found to be proportional to the observed end slip.

Polarisation of very-low-mass stars and brown dwarfs
, 2009 Ultra-cool dwarfs of the L spectral type (Teff=1400-2200K) are known to have dusty atmospheres. Asymmetries of the dwarf surface may arise from rotationally-induced flattening and dust-cloud coverage, and may result in non-zero linear polarisation ...

Advanced Functional Materials, EarlyView.An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...
