• Copolymeric succinamic acids as antiwear additives: Synergistic and adverse effects
  作者：A. K. Mehrotra、T. Nandi、R. K. Agnihotri、G. N. Mathur

  Copolymeric succinamic acid (COSMA) additives have been synthesised in the laboratory and evaluated for their antiwear performance, both alone and in combination with zinc dialkyl-dithiophosphate (ZDDP) in HVI light neutral oil. COSMA additives show antiwear behaviour and, in combination with ZDDP, exhibit a good synergistic effect, reducing the wear-scar diameter by 60% and increasing the initial

• Electron spin resonance studies of fundamental processes in radiation and photo-chemistry. Part 4.—γ-Irradiated potassium alkyl sulphates between 77 and 300°K
  作者：P. B. Ayscough、A. K. Roy

  DOI：10.1039/tf9676301106

  日期：——

  The effect of ionizing radiation on potassium methyl and ethyl sulphates has been examined, using electron spin resonance to identify the trapped paramagnetic species. After γ-irradiation at 77°K the radicals ĊH2OSO–3 and CH3ĊHOSO–3 predominate in the methyl and ethyl compounds respectively, and some SO–3 is seen. Above 200°K only SO–3 remains; its identity was confirmed by an analysis of the 33S hyperfine interaction. Mechanisms for the radiolysis are discussed.

  对离子辐射对甲基和乙基硫酸盐的影响进行了研究，使用电子自旋共振来识别捕获的顺磁性物种。经77K下的γ辐射后，甲基和乙基化合物中主要出现了自由基CH2OSO₃⁻和CH3CHOSO₃⁻，并观察到一些SO₃⁻。在200K以上，仅剩下SO₃⁻；其身份通过对33S超精细相互作用的分析得到了确认。讨论了辐解的机制。

  suitability as methoxy reference materials. Firstly, the stable hydrogen and carbon isotope values of the bulk compounds were calibrated against international reference substances by high-temperature conversion- and elemental analyser isotope ratio mass spectrometry (HTC- and EA-IRMS). In a second step these values were compared with values obtained by measurements using gas chromatography/isotope

  理性的植物有机质甲氧基（OCH3）氢和碳同位素比率稳定，在生物地球化学，大气和食品研究中具有许多潜在应用。到目前为止，大多数通过同位素比率质谱法对植物甲氧基进行的分析均采用液态碘甲烷（CH3 I）作为参考材料，将这些部分的稳定同位素测量值标准化为同位素δ级。但是，由于缺少合适的参考物质，仍然无法比较植物甲氧基的稳定氢和碳同位素的测量结果。方法我们研究了两种甲基硫酸盐（HUBG1和HUBG2），它们仅包含一个甲氧基的碳和氢，以适合用作甲氧基参考物质。首先，通过高温转化和元素分析仪同位素比质谱（HTC-和EA-IRMS），对照国际参考物质校准了大块化合物的稳定氢和碳同位素值。在第二步骤中，将这些值与通过使用气相色谱/同位素比率质谱法（GC / IRMS）的测量获得的值进行比较，其中在分析之前，将甲氧基基团转化为气态的碘甲烷。结果用HTC-和EA-IRMS测量的HUBG1的2 H和13 C同位素
