Dual frequency comb generated on a single chip using a single laser on Science stuff

March 3, 2018, 2:45 a.m.

Engineers have miniaturized dual-frequency combs by putting two frequency comb generators on a single millimeter-sized silicon-based chip. This could lead to low-cost, portable sensing and spectroscopy in the field in real-time.https://www.sciencedaily.com/releases/2018/03/180302144838.htm

A novel way to synthesize antioxidant substances on Science stuff

Dec. 26, 2017, 8:57 a.m.

Scientists have proposed a novel way to address the most important and fundamental challenge of organic chemistry, such as breaking a bond between carbon and hydrogen atoms to form new organic substances. They were the first to carry out “breaking” in water thanks to especially synthesized substances called arylbenziodoxaboroles. As a result, the scientists synthesized a number of novel phenolic substances that possess high biological and antioxidant activity. In the future, they can be used for drug creation. https://www.sciencedaily.com/releases/2017/12/171222092506.htm

O Naufragio do Rio Apa on Cemiterio de navios / Ship cemetery

Jan. 16, 2019, 8:44 p.m.

1887, ainda não havia molhes na barra da Lagoa dos Patos, ingressar no porto era (e ainda é) uma manobra complexa e arriscada. O navio Rio Apa vinha do Rio de Janeiro em direção a Montevideo trazendo cerca de 126 pessoas a bordo. Faria uma parada em Rio Grande para embarque e desembarque de passageiros. Construido nos estaleiros da Henry Murray Co, de Glasgow, Escócia em 1879 o Rio Apa era um luxuoso navio de passageiros de cerca de 67m de comprimento com deslocamento de 902t.
