The crystal orientation of poly(ε-caprolactone) (PCL) homopolymers, spatially confined in cylindrical nanodomains surrounded by polystyrene (PS) matrices, has been investigated as a function of crystallization temperature T c (−60 °C ≤ T c ≤ −40 °C) using two-dimensional small-angle X-ray scattering (2D-SAXS) and wide-angle X-ray diffraction (2D-WAXD). The sample was prepared by microphase separation of an PCL-block-PS copolymer followed by photocleavage at the block junction between PCL and PS blocks. The results were compared with crystal orientation of PCL blocks before photocleavage, i.e., PCL chains with one chain-end tethered at the cylinder interface. The lamellar crystals of PCL homopolymers and PCL blocks were preferentially oriented in cylindrical nanodomains irrespective of T c, i.e., the b axis of crystal unit cells was oriented parallel to the long axis of cylinders. The degree of crystal orientation increased remarkably with increasing T c for PCL homopolymers, whereas it improved slightly for PCL blocks, yielding a large difference in the degree of crystal orientation between two systems at higher T c (≥−45 °C).

The present paper is the Supplemental materials for our original paper entitled “highly active, homogeneous catalysis by polyoxometalate-assisted N -heterocyclic carbene gold(I) complexes for hydration of diphenylacetylene. The present article refers to the preparations of several monomeric, N -heterocyclic (NHC) carbene/carboxylate ( RS -pyrrld)/gold(I) complexes, [Au( RS -pyrrld)(NHC)] (NHC = IMes ( 6 ), BIPr ( 7 ), IF 3 ( 8 ), I t Bu ( 9 )), which were used for homogenous catalysis of the hydration reaction of diphenylacetylene to afford deoxybenzoin. The article also includes the preparations of the precursor complexes, [AuCl(NHC)] (NHC = IPr, IMes, BIPr, IF 3 , I t Bu), and novel X-ray crystallography of the separately prepared [Au(IPr)(H 2 O)] 3 [α-PW 12 O 40 ]·7Et 2 O ( 2 ), summary of crystal data of ( 2 ), and selected bond distances (Å) and angles (deg) of ( 2 ). Also presented are Cartesian coordinates of the optimized structures in the quantum-mechanical calculations.

Different grinding wheel surface conditions affect the ground surface roughness and grinding resistance during the grinding process. In addition, as the grinding wheel surface condition changes depending on the dressing conditions, the difference in the dressing conditions significantly affects the grinding characteristics. However, the dressing condition is affected by factors such as the dressing lead, depth of dressing cut, and tip shape of the dresser. Thus, optimum dressing conditions are difficult to achieve. Furthermore, even if the dressing is applied under the same dressing conditions, the grinding wheel surface condition will differ as the tip wear of the dresser progresses. There is a need for a method to quantitatively evaluate the relationship between the dressing conditions, grinding wheel surface condition, and grinding characteristics while considering the difference in the tip shape of the dresser. Thus, the relationship between the tip shape of the dresser and dressing conditions was evaluated using the dressing overlap ratio. This study aimed to evaluate the effect of different dressing overlap ratios on the grinding wheel surface condition and grinding characteristics with different grain sizes. Consequently, even if the tip shape of the dresser changes, the effect of the different dressing conditions on the grinding wheel surface condition and grinding characteristics could be quantitatively determined using the dressing overlap ratio. Furthermore, the relationship between the calculated successive cutting-point spacing, area of active abrasive grains, and grinding characteristics could be quantitatively evaluated for grinding wheels with different grain sizes.
