“…By using the reported kinetics of solvolysis (see the Supporting Information, part 7),– together with the N f and s f parameters for Br − and Cl − in various solvent mixtures, plots of (log k ion )/ s f against N f were constructed (Figure ) and thus gave access to the electrofugality parameters E f of the five phenylfluorenyls 2(b–f) (Table ).…”

The isolation, characterization, and the first X-ray structures of a fluorenylium ion and its Lewis adducts with nitrogen- and phosphorus-centered Lewis bases are reported. Kinetics of the reactions of a series of fluorenylium ions with reference π-, σ-, and n-nucleophiles of various sizes and nucleophilicities allowed the interplay between electronic and structural parameters on the electrophilicities of these planarized tertiary carbenium ions to be elucidated. Structure-reactivity correlations and extensive comparisons of their reactivities with those of di- and triarylcarbenium ions are described. Quantitative determination of the electrofugalities of fluorenylium ions revealed to which extent they are complementing tritylium ions as protecting groups and how their tuning is possible. Determination of the equilibrium constants of the Lewis adducts formation between pyridines of calibrated Lewis basicities and phenylfluorenylium and tritylium ions allowed the determination of their Lewis acidities and to showcase the potential of these carbon-centered Lewis acids in catalysis.

“…Since the existence and location of the critical point is still unknown, we need an algorithm which can be applied beyond the small chemical potential region. This is one of the motivations of our studies via the canonical ensemble approach [20,21,22,23,24].…”

“…To generate this ensemble a candidate configuration is "proposed" by the standard Hybrid Monte Carlo algorithm [38,39,40,41], then an accept/reject step is used to correct the weight. We note that the accept/reject step is based on the determinant ratio which alleviates the fluctuation problem [42,22,25] and enhances the acceptance rate [26].…”

The existence of the QCD critical point at non-zero baryon density is not only of great interest for experimental physics but also a challenge for the theory. Any hint of the existence of the first order phase transition and, particularly, its critical point will be valuable towards a full understanding of the QCD phase diagram. We use lattice simulation based on the canonical ensemble method to explore the finite baryon density and finite temperature region and look for the QCD critical point. As a benchmark, we run simulations for the four degenerate flavor QCD where we observe a clear signal of the expected first order phase transition. In the two flavor case, we do not see any signal for temperatures as low as 0.83 T c . Although our real world contains two light quarks and one heavier quark, three degenerate flavor case shares a lot of similar phase structures as the QCD. We scan the phase diagram using clover fermions with m π ≈ 700MeV on 6 3 × 4 lattices. The baryon chemical potential is measured as we increase the baryon number and we see the characteristic "S-shape" that signals the first order phase transition. We determine the phase boundaries by Maxwell construction and report our preliminary results for the location of critical point for the present lattice.The XXVII International Symposium on Lattice Field Theory

“…This class of materials has been extensively studied for their potential applications in actuation, energy conversion and charge storage [1][2][3][4]. However, up to now all the investigations were performed on polycrystalline PLZST samples [5][6][7][8][9][10], and their practical use was limited to sintered ceramics consisting of randomly oriented crystal grains. If the appropriate axis is utilized, single crystals generally have superior properties than the polycrystalline ceramics, for example PMN-PT [11][12][13], PZN-PT [14][15][16] However, few studies have reported PLZST single crystal growth to our knowledge.…”
