| 1 | Pilot study on binding of bovine salivary proteins to grit silicates and plant phytoliths显示文摘Mostly fed with grass in fresh or conserved form, cattle and other livestock have to cope with silicate defence bodies from plants (phytoliths) and environmental silicates (grit), which abrade tooth enamel and could additionally interact with various salivary proteins. To detect potential candidates for silicate-binding proteins, bovine whole saliva was incubated with grass-derived phytoliths and silicates. Interactions of salivary proteins with pulverized bovine dental enamel and dentine were additionally analysed. After intense washing, the powder fractions were loaded onto 1D-polyacrylamide gels, most prominent adhesive protein bands were cut out and proteins were identified by mass spectrometry within three independent replicates. All materials were mainly bound by bovine odorant-binding protein, bovine salivary protein 30×103 and carbonic anhydrase VI. The phytolith/silicate fraction showed additional stronger interaction with haemoglobin β and lactoperoxidase. Conceivably, the binding of these proteins to the surfaces may contribute to biological processes occurring on them. | Marcus MAU Thomas M.KAISER Karl-Heinz SüDEKUM | 2013 | Zoological Research2013，34，3： | 0 |
| 2 | Overview of SwissFEL dual-photocathode laser capabilities and perspectives for exotic FEL modes显示文摘SwissFEL is a compact,high-brilliance,soft and hard X-ray free electron laser(FEL)facility that started user operation in 2019.The facility is composed of two parallel beam lines seeded by a common linear accelerator(LINAC),and a two-bunch photo-injector.For the injector,an innovative dual-photocathode laser scheme has been developed based on state-of-the-art ytterbium femtosecond laser systems.In this paper,we describe the performance of the Swiss FEL photocathode drive lasers(PCDLs),the pulse-shaping capabilities as well as the versatility of the systems,which allow many different modes of operation of Swiss FEL.The full control over the Swiss FEL electron bunch properties via the unique architecture of the PCDLs will enable in the future the advent of more-advanced FEL modes;these modes include,but are not restricted to,the generation of single or trains of sub-femtosecond FEL pulses,multi-color FEL and finally,the generation of fully coherent X-ray pulses via laser-based seeding. | S.Bettoni A.Cavalieri A.Dax E.Divall C.P.Hauri S.Hunziker M.Huppert M.Kaiser M.Paraliev C.Sydlo C.Vicario A.Trisorio | 2021 | High Power Laser Science and Engineering2021，9，4： | 0 |
| 3 | Polar comonomer incorporation using cationic Ni α-diimine olefin polymerization catalysts显示文摘Polyolefins are an indispensable class of materials that have become the most widely produced and utilized polymers today.They are readily synthesized from cheap and abundant monomer feedstocks,such as ethylene and propylene,and are capable of achieving a vast array of thermal and mechanical properties based upon their composition and topology.However,despite their numerous advantages, polyolefins are typically devoid of functional groups which can limit their applicability to many product families,such as coatings,adhesives,and cross-linked polyolefins. | Jordan M.Kaiser Brian K.Long | 2019 | Science China Chemistry2019，62，2： | 0 |
