Laboratory Clothing and Personal Protective Equipment A. Dressing for safety in the laboratory Individuals should prepare for a safe laboratory experience by dressing appropriately for laboratory work. Appropriate clothing includes the following: • Shoes should fully cover the feet to protect against spills; no open-toed shoes or sandals are permitted, and shoes with mesh inserts (such as athletic shoes) are not recommended. One may choose to keep a pair of sturdy leather shoes in the laboratory to change into upon arrival. • Trousers or skirts falling below the knee are preferred; if shorter garments are worn, a lab coat or apron of below knee length is required. Preferred materials are resistant polyester, cotton or wool, since ordinary polyester and acrylics may be dissolved by common laboratory solvents. • Neckties, if worn, should be firmly clipped to the shirt or confined inside a lab coat or apron. • Loose, flowing garments and scarves should be avoided; they may easily pick up spills or trail through a burner flame. • In a laboratory where open flames may be used, long hair should be confined. • Loose jewelry should be avoided, since it may catch on equipment. Also avoid ornate rings that can damage protective gloves or make wearing or removing gloves difficult B. Protective Equipment Every laboratory must have available, and workers must be trained in the use of, safety goggles, face masks, lab coats or aprons, gloves, and reaction shields.

Zakharchenko1 · Alina I. Belova1 · Alexander S. Frolov1 · Olesya O. Kapitanova1 · Juan‑Jesus Velasco‑Velez2 · Axel Knop‑Gericke2,5 · Denis Vyalikh3,4 · Daniil M. Itkis1 · Lada V. Yashina1 © Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract One of the key factors responsible for the poor cycleability of Li–O2 batteries is a formation of byproducts from irreversible reactions between electrolyte and discharge product Li 2O2 and/or intermediate LiO2. Among many solvents that are used as electrolyte component for Li–O2 batteries, acetonitrile (MeCN) is believed to be relatively stable towards oxidation. Using near ambient pressure X-ray photoemission spectroscopy (NAP XPS), we characterized the reactivity of MeCN in the Li–O2 battery. For this purpose, we designed the model electrochemical cell assembled with solid electrolyte. We discharged it first in O2 and then exposed to MeCN vapor. Further, the discharge was carried out in O2 + MeCN mixture. We have dem- onstrated that being in contact with Li–O2 discharge products, MeCN oxidizes. This yields species that are weakly bonded to the surface and can be easily desorbed. That’s why they cannot be detected by the conventional XPS. Our results suggest that the respective chemical process most probably does not give rise to electrode passivation but can decrease considerably the Coulombic efficiency of the battery. Keywords Li–O2 battery · In situ NAP XPS · Acetonitrile · Side reactions 1 Introduction Li–O2 batteries promise extraordinary high specific energy that makes them interesting for the next generation power technologies [1, 2].

  • REACH - Registration, Evaluation, Authorisation and Restriction of Chemical Substances

    REACH - Registration, Evaluation, Authorisation and Restriction of Chemical Substances

    REACH - Registration, Evaluation, Authorisation and Restriction of Chemical Substances TERRITORY European Union RESTRICTION SUBJECT Human Health and Environment Protection against adverse effects of chemical substances The European Commission elaborated a Directive (EC 1907/2006) known as REACH with the aim to ensure Human Health and Environment Protection against adverse effects of chemical substances. The Directive imposes - to all companies conducting business with chemical substances - to adopt compulsorily “a special chemical substances work regime”. (REACH is valid from 1st of July 2007.) Producers, importers and follow-up users of chemical substances and/or substances contained in preparations and in items must, in compliance with the Directive, ask for their registration at the European Chemical Agency as of 1st of June 2008. The obligation to register in relation with chemical composition is mainly related to chemical substances and preparations made of them, but not according to the article 7, the paragraph 1 of the REACH Directive to final products, i.e. items which can be considered – under standard or reasonable foreseeable conditions of use – as completely safe. Preciosa does not supply either chemical substances or chemical preparations or mixtures on the market. The products that we supply are final products that meet the above mentioned requirements. This means that they are not subject to the REACH registration. Preciosa guarantees to the customer that all products of Preciosa are in conformity with requirements specified in COMMISSION REGULATION (EU) No 217/2016 of 16 February 2016 amending Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) as regards Annex XVII.
