伯格伦德说:“我们已经研究了光的去向,以及当光照射到纤维素上时会发生什么。”“有些光直接穿过木材,并使材料透明。有些光以不同角度折射和散射,并在照明应用中产生令人愉悦的效果。”该团队还与KTH的谢尔盖·波波夫(Sergei Popov)的光子学小组合作,进一步探索纳米技术的可能性。 The sustainable development of en...

Cf = 2.n.fo2/(Uq.Pq)1/2 (eqn. 3) where n = number of the harmonic at which the crystal is driven, fo = the resonant frequency of the fundamental mode of the crystal in Hz, Uq = density of quartz = 2.648 g cm-3, Pq = shear modulus of quartz = 2.947.1011 g.cm-1.s-2....
The addition of Nb gradually increased the Young’s modulus E from 68 (x = 0) to 101 GPa (x = 6), the shear modulus K from 25 (x = 0) to 38 GPa (x = 6), and the bulk modulus K from 94 (x = 0) to 105 GPa (x = 6), respectively. However, E = 96 GPa and K = ...
where E is Young’s modulus, ν is Poisson’s ratio, e 1 , e 2 , and e 3 are the tensile strains (or stretches) in a Voigt notation, and σ h h , σ v v , and σ z z are the normal components of the stress tensor. The labelling of the coordinate axes is chosen so that...
The density ρ, Young's modulus E, the thermal expansion coefficient α, and the temperature cofficient of Young's modulus e were measured with the alloys of iron and palladium cooled in a furnace after having been annealed at 1000°C to asscertain whether the rule on the small expansibilit...
the accordingr-value was at such a low level. This was due to the high irregularity of the Young’s moduli of the metal fibres (e.g. CV (Young’s modulus) = 36% for 1.4113). The relationship between the fibre count and elongation at maximum tensile stress had a medium effect. ...

Using atomic force microscopy and force volume experiments with CNC-functionalized levers, increasing the relative humidity is shown to decrease the Young's modulus values of the different films and promote their adhesion forces with CNCs. In particular, CNCs more strongly interact with glucomannan and...
In this study phase detection imaging (PDI) and Young's modulus microscopy (YMM) have been used for investigation of ZnS thin films deposited on Si(100) substrates with successive ionic layer adsorption and reaction (SILAR). The additional information obtained by these techniques allows a better ...
