[1] This study investigates the effects of cloud condensation nuclei (CCN) and ice nuclei (IN) on ice formation in mixed-phase clouds using an adiabatic parcel model. The simulations with lower updrafts represent mixed-phase stratiform clouds, and those with higher updrafts represent deep convective clouds. Increasing CCN concentration can lead to more ice crystals with smaller sizes, but does ...

We explore the gel transition of the aromatic dipeptide derivative molecule fluorenylmethoxycarbonyl-diphenylalanine (Fmoc-FF). The addition of water to a solution of Fmoc-FF in dimethyl sulfoxide (DMSO) results in increased attractions leading to self-assembly of Fmoc-FF molecules into a space-filling fibrous network. We provide evidence that gel formation is associated with a first order phas...

High temperature-resolution N Q R measurements in an ul t ra pure Rb 2 ZnCl 4 crystal and a mixed [Rb[ _ x ( N H 4 ) J 2 Z n C l 4 crystal w i th a control led amount of impurit ies (x = 0.01) verify the existence of a temperature region where the characteristic incommensurate line split t ing is averaged out. The results show that for the system wi th high pur i ty the averaging of the incomme...

To study the photodegradation of organic pollutants at the interface of minerals and water in natural environment, three series of alumina-coupled iron oxides (Al(2)O(3)-Fe(2)O(3)-300, Al(2)O(3)-Fe(2)O(3)-420, and Al(2)O(3)-Fe(2)O(3)-550) with different alumina fraction were prepared and characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) and Barret-Joyner-Halender (BJH), and...

Dielectric properties, including linear (refractive index) and second-order nonlinear optical responses, of LiNb12yTayO3-type mixed single crystals with y ˆ 0:00; 0.81, 0.92, 0.97, and 1.00 have been quantitatively studied. Based on the corresponding crystal compositions, the chemical bond method was applied. The results show that the dielectric susceptibilities at 1.064 mm decrease remarkably ...

objective(s):the inhibitory effects of iron chelators, and fecl3 chelation on biofilm formation and swarming motility were investigated against an opportunistic human pathogen pseudomonas aeruginosa. materials and methods:the inhibitory activity of 2,2’-bipyridyl, lipoic acid, kojic acid and picolinic acidonbiofilm formation of p. aeruginosa strain pao1 and three clinical isolates (p. aeruginos...

High pressure mercury, nitrogen adsorption, nano-CT, and scanning electron microscope with energy spectrum analysis were conducted on core shale samples for studying the characteristics of Taiyuan formation in the eastern uplift of Liaohe depression. The research results show that the shale gas reservoir pores are mainly open pores such as the wedge-shape pores and parallel-plate pores. By a ge...

Reactions of diphenyltellurium oxide with organostibonic acid and polymeric triphenylantimony oxide have been investigated independently. Single crystal X-ray diffraction studies have revealed the formation of novel and rare mixed valent Sb(v)/(iii) containing polyoxostibonates {(C6H5)3Te}2{Na2(H2O)2(p-Br-C6H4Sb(V))10(Sb(III))4[(C6H5)2Te]4(O)30(OH)4} and {(C6H5)3Te}4{[(C6H5)2Sb(V)]4(Sb(III))4(O...

A self-assembled multilayer based on a mixed MHDA-Biotinyl PE self-assembled monolayer followed by the addition of a biotin-avidin system was built up on a the gold electrode of a quartz crystal microbalance which was used to monitor the deposition. With the view to producing an odorant sensing device, an olfactory receptor (OR), ORI7, was immobilized on the self-assembled multilayer. The ORI7 ...
