1用于高性能轮胎的环烷基增塑剂显示文摘目前开发节能环保轮胎已成为轮胎行业研究的前沿课题之一。近年来,增塑油在轮胎性能中所起的作用已显现出来。本文研究了环烷基增塑剂对轮胎性能的影响。研究结果表明,环烷基操作油Nytex230能明显改善轮胎的滚动阻力和湿路面抓着性,这意味着改善了燃油经济性和降低了二氧化碳(CO_2)排放量。与操作油TDAE相比,低芳香烃含量的增塑剂在保持机械性能相似的前提下能提高生产效率。代高峰 Markus Hoffmann 2015现代橡胶技术2015,41,1:4
2Profound neutralization evasion and augmented host cell entry are hallmarks of the fast-spreading SARS-CoV-2 lineage XBB.1.5显示文摘Since late 2022, the share of infections caused by the SARS-CoV2 lineage XBB.1.5 has gradually increased in the United States,resulting in XBB.1.5 becoming the dominating SARS-CoV-2lineage in the United States and a similar trend is likely to soontake place also in European countries. However, information onthe virological properties of XBB.1.5 is scarce. Here, weconducted an initial virological assessment of the SARS-CoV-2XBB.1.5 lineage.Markus Hoffmann Prerna Arora Inga Nehlmeier Amy Kempf Anne Cossmann Sebastian R.Schulz Gema Morillas Ramos Luis A.Manthey Hans-Martin Jäck Georg M.N.Behrens Stefan Pöhlmann 2023Cellular & Molecular Immunology2023,20,4:2
3瑞典农业用地中的氮淋溶——降低淋溶负荷措施的模型计算效果显示文摘本文进行计算的主要目的在于:①估计耕地中氮淋溶减少措施的效果;②预计瑞典南部总负荷的减少量。采取的主要措施有:①春季谷类作物中种植填闲作物;②在不施粪肥的耕作制度下,减少氮肥的施用量;③春季施用粪肥和少量施用氮肥;④春季种植填闲作物结合施用粪肥并逐渐减少氮肥用量。本文所用的模型是用于描述土壤剖面水、热和氮淋溶的SOIL/SOILN机制模型。氮淋溶过程中的最大减少量是通过种植填闲作物,春季施粪肥与逐渐减少氮肥的施用量相结合而获得的。这种做法使总负荷量减少了16%。但由于春季作物中仅仅30%的面积种植了填闲作物,填闲作物仅将总负荷减少了5%。氮肥减少10%,将导致负荷减少6000t(即减少11%),同时产量减少10%左右。Markus Hoffmann Holger Johnsson 潘英姿 2000AMBIO-人类环境杂志2000,29,2:2
4Resonance-enhanced multi-octave supercontinuum generation in antiresonant hollow-core fibers显示文摘Ultrafast supercontinuum generation in gas-filled waveguides is an enabling technology for many intriguing applications ranging from attosecond metrology towards biophotonics,with the amount of spectral broadening crucially depending on the pulse dispersion of the propagating mode.In this study,we show that structural resonances in a gas-filled antiresonant hollow core optical fiber provide an additional degree of freedom in dispersion engineering,which enables the generation of more than three octaves of broadband light that ranges from deep UV wavelengths to near infrared.Our observation relies on the introduction of a geometric-induced resonance in the spectral vicinity of the ultrafast pump laser,outperforming gas dispersion and yielding a unique dispersion profile independent of core size,which is highly relevant for scaling input powers.Using a krypton-filled fiber,we observe spectral broadening from 200 nm to 1.7μm at an output energy of B 23μJ within a single optical mode across the entire spectral bandwidth.Simulations show that the frequency generation results from an accelerated fission process of solitonlike waveforms in a non-adiabatic dispersion regime associated with the emission of multiple phase-matched Cherenkov radiations on both sides of the resonance.This effect,along with the dispersion tuning and scaling capabilities of the fiber geometry,enables coherent ultra-broadband and high-energy sources,which range from the UV to the mid‐infrared spectral range.Rudrakant Sollapur Daniil Kartashov Michael Zürch Andreas Hoffmann Teodora Grigorova Gregor Sauer Alexander Hartung Anka Schwuchow Joerg Bierlich Jens Kobelke Mario Chemnitz Markus A Schmidt Christian Spielmann 2017Light(Science & Applications)2017,6,1:2
5Low serum neutralizing anti-SARS-CoV-2 S antibody levels in mildly affected COVID-19 convalescent patients revealed by two different detection methods显示文摘Neutralizing antibodies targeting the receptor-binding domain(RBD)of the SARS-CoV-2 spike(S)block severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)entry into cells via surface-expressed angiotensin-converting enzyme 2(ACE2).We used a surrogate virus neutralization test(sVNT)and SARS-CoV-2 S protein-pseudotyped vesicular stomatitis virus(VSV)vector-based neutralization assay(pVNT)to assess the degree to which serum antibodies from coronavirus disease 2019(COVID-19)convalescent patients interfere with the binding of SARS-CoV-2 S to ACE2.Both tests revealed neutralizing anti-SARS-CoV-2 S antibodies in the sera of ~90% of mildly and 100% of severely affected COVID-19 convalescent patients.Importantly,sVNT and pVNT results correlated strongly with each other and to the levels of anti-SARS-CoV-2 S1 IgG and IgA antibodies.Moreover,levels of neutralizing antibodies correlated with the duration and severity of clinical symptoms but not with patient age.Compared to pVNT,sVNT is less sophisticated and does not require any biosafety labs.Since this assay is also much faster and cheaper,sVNT will not only be important for evaluating the prevalence of neutralizing antibodies in a population but also for identifying promising plasma donors for successful passive antibody therapy.Berislav Bosnjak Saskia Catherina Stein Stefanie Willenzon Anne Katrin Cordes Wolfram Puppe Gunter Bernhardt Inga Ravens Christiane Ritter Christian R.Schultze-Florey Nina Godecke Jorg Martens Hannah Kleine-Weber Markus Hoffmann Anne Cossmann Mustafa Yilmaz Isabelle Pink Marius M.Hoeper Georg M.N.Behrens Stefan Pohlm ann Rainer Blasczyk Thomas F.Schulz Reinhold Forster 2021Cellular & Molecular Immunology2021,18,4:2

9瑞典耕地的氮淋溶——1985和1994年的标准速率和总传输显示文摘本文估计了1985和1994年波罗的海和北海集水区的氮淋溶总传输,是瑞典公布的将氮向海传输量减少50%的议案所展开的研究一部分。采用一模拟模型对不同区域、作物、土壤和施肥方式下的标准淋溶速率进行了计算。标准淋溶速率是正常气候和收获条件下每年从根区淋溶的氮量。结果表明:氮淋溶量减少了25%,从1985年的30kg N/hm^2到1994年的22kg N/hm^2。氮的总传输量减少了29%,从1985年的77000t到1994年的55000t。减少的主要原因是:①1994年草地面积的增加和谷物面积的减少;②氮利用效率的增加导致单一作物标准淋溶速率的减少;③耕地总面积的减少。传输量减少的原因50%归因于谷物地向草地的转换,40%归因于氮利用效率的提高,10%归因于耕地的减少。Holger Johnsson Markus Hoffmann 周才平 1998人类环境杂志1998,27,6:1
