Determination of total titanium in titanium metal and titanium tetrachloride
BUNSEKI KAGAKU, 1961 金属チタンおよび四塩化チタン中の全チタンの定量法につき,簡易化と迅速化の見地から容量法を詳細に研究し,つぎの諸方法を確立した.金属チタンは試料をフッ化水素酸と硫酸にとかし,ホウ酸を加えて液状亜鉛アマルガムで還元する.のち四塩化炭素を加えて液状亜鉛アマルガムを分離し,還元液を硫酸第二鉄アンモニウム溶液で滴定し全チタンを求める四塩化チタンは試料を注射針付き注射器で塩酸に注入溶解させる.のち試料がバナジウムを含まない場合は金属チタンと同様に還元,滴定する.またバナジウム含有の場合は塩酸溶液に硫酸と過酸化水素水を加え硫酸白煙ののち液状亜鉛アマルガム還元,過マンガン酸カリウム滴定を行ない別に求めたバナジウム含量により補正を行なう.分析精度を変異係数(σ%)で示せば金属チタンで約0.1%,四塩化チタンで約0 ...

Advanced Engineering Materials, EarlyView.Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

JAMA: The Journal of the American Medical Association, 1884 Read before the Detroit Academy of Medicine, November 18, 1884. Gentlemen of the Academy: The use of a class of remedies whose composition is either wholly the secret of the manufacturer, or else is deliberately misrepresented in the statements purporting to give an account of their composition, seems to be gaining ground among reputable physicians ...

Advanced Engineering Materials, EarlyView.Temporal power modulation increases weld depth in high‐power laser beam welding of dissimilar round bars by nearly 20% compared to same average continuously welded welding power. The mechanism of action also applies to sheet welding and depends on the inertia of keyhole depth for the modulated laser beam power.
