合成氨基酸,是化学教授Allen J.Bard和他在奥斯丁的得克萨斯大学的同事们,在进行镀铂二氧化钛和其他半导体材料的研究工作中的最新成果。合成氨基酸的试验,是照射20毫升含100毫克镀铂二氧化钛粉末的氨或氯化铵溶液,并使甲烷缓慢地鼓泡[J.Am.Chem.Soc.,101,3127,(1979)]。一个2.5千瓦的氙灯在1,5千瓦下工作,照射64—66小时。用氯化铵溶液和氨分别约产生500和200毫微克分子的氨基酸。得到的氨基酸是由甘氨酸、丙氨酸、络氨酸、天冬氨酸、谷氯酸等组成的混合物。在实验室工作的基础上,该试验证明用一个氙灯或太阳光照射悬浮的镀铂二氧化钛时,能促进几种溶液的反应,这些 Synthetic amino acids, the latest in Allen Platinum, professor of chemistry and his colleagues at the University of Texas in Austin, are engaged in research into platinized titanium dioxide and other semiconducting materials. Amino acid synthesis was tested by irradiating 20 ml of ammonia or ammonium chloride solution containing 100 mg of platinized titanium dioxide powder and slowly bubbling methane [J. Am. Chem. Soc., 101, 3127, (1979)]. A 2.5 kilowatts xenon lamp at 1,5 kilowatts work, irradiation 64-66 hours. Approximately 500 and 200 nanograms of amino acids are produced with ammonium chloride solution and ammonia, respectively. The resulting amino acid is a mixture of glycine, alanine, tyrosine, aspartic acid, glutamic acid, and the like. Based on laboratory work, this test demonstrates that irradiation of suspended platinum-coated titanium dioxide with a xenon lamp or sunlight can promote the reaction of several solutions, these
