Following a simple and practical approach can minimize the headaches of calculating the components of measurement uncertainty. Basic requirements for planning an analysis, realistically estimating the magnitude of uncertainty sources, and combining uncertainty components will be presented using examples of analytical chemistry methods.

Recently the concept of regression depth has been introduced [1]. The deepest regression (DR) is a method for linear regression which is defined as the fit with the best depth relative to the data. In this paper we explain the properties of the DR and give some applications of deepest regression in analytical chemistry which involve regression through the origin, polynomial regression, the Mich...

The disciplines curricula on green chemistry and sustainable available in various universities of the world were analysed. Trends education development science this particular area described as well actual teaching problems that need to be solved. Analysing data obtained three approaches defining a trajectory for basic foundations identified: British, European, American. first one involves in-d...

The Beilstein Journal of Organic Chemistry (BJOC) was started in 2005 [1] as the first Open Access journal of the BeilsteinInstitut. The Beilstein-Institut is a non-profit foundation that carries out projects supporting advances in chemical sciences and related areas, particularly through information and communication. The aim of the Beilstein Journal of Organic Chemistry has been to provide a ...

This article analyzes how chemical manufacturers can develop stronger business advantages for green chemistry by rethinking sustainability marketing approaches. Green chemistry is a package of technologies, design principles and tools to reduce the toxicity, resource and energy use, and pollution of chemicals. Using research into US chemical industry efforts, this article introduces green chemi...

epoxides undergo regioselective ring opening with various nucleophiles using catalytic amount of nano magnesium oxide and water as solvent under mild reaction conditions. the remarkable features of this method are improved yields, high regioselectivity, and green chemistry agreement.

In this paper we discuss the structural chemistry of (PPh(4))(2)M(WS(4))(2) (M = Co, Ni, Zn) materials. For M = Ni we and others have been unable to grow single crystals and we report the structure determination from powder diffraction. The material is triclinic (P1, a = 9.3730(2), b = 12.4951(3), c = 12.5189(3) A, alpha = 65.814(1), beta = 83.751(1), gamma = 69.571(1) degrees at T = 293 K). It...

Radiometals play an important role in diagnostic and therapeutic radiopharmaceuticals. This field of radiochemistry is multidisciplinary, involving radiometal production, separation of the radiometal from its target, chelate design for complexing the radiometal in a biologically stable environment, specific targeting of the radiometal to its in vivo site, and nuclear imaging and/or radiotherapy...
