Homochirality of amino acids, sugars, proteins, and DNA is one of the biochemical hallmarks of life on Earth. Its origins have been debated for decades. Given that minerals such as quartz were probably the first enantiomerically pure materials on Earth, it has been suggested that such materials served as chiral substrates for enantiospecific surface chemistry. Enantiospecific adsorption on the ...
We report the most sensitive direct search for pair production of fourth-generation bottomlike chiral quarks (b') each decaying promptly to tW. We search for an excess of events with an electron or muon, at least five jets (one identified as due to a b or c quark), and an imbalance of transverse momentum by using data from pp collisions collected by the CDF II detector at Fermilab with an integ...
It has been known for some time that the Boltzmann weights of the chiral Potts model can be parametrized in terms of hyperelliptic functions, but as yet no such parametrization has been applied to the partition and correlation functions. Here we show that for N = 3 the function S(t p) that occurs in the recent calculation of the order parameters can be expressed quite simply in terms of such a ...
This review focuses on the recent advances on microscale separation technology, particularly on the new development on column and detection technologies in electrophoretic and chromatographic separation modes (i.e., CE, CEC, cLC, etc.). Representative examples illustrate also applications on the small molecules, peptides, proteins, polysaccharides, chiral and so on. 246 relevant articles are ci...
A bstract Chiral Separation Effect (CSE) for systems that feature spin 3/2 fermions was considered. For the self-consistent Adler’s model with relativistic massless Rarita-Schwinger (RSA model), we found CSE conductivity is five times larger than Dirac fermions. a of four-fold band crossing in Rarita-Schwinger-Weyl semimetals, which quasispin exist, calculated four Weyl We show any multi-degene...
Charged cyclodextrin (CD) derivatives were used as chiral selectors in electrokinetic chromatography (EKC) for the chiral separation of highlyhydrophobic neutral racemates such as atropisomeric polychlorinated biphenyls (PCBs). -CD-phosphated, -CD sulfated, succinylated-CD (Succ-CD) and succinylated-CD (Succ-CD) were used as anionic CDs. As cationic CD, 6-monodeoxy-6-monoamino-CD ( -CD-NH2) was...
