Lithium-ion batteries are the most commonly used source of power for modern electronic devices. However, their safety became a topic of concern after reports of the devices catching fire due to battery failure. Making safer batteries is of utmost importance, and several researchers are trying to modify various aspects in the battery to make it safer without affecting the performance of the battery. Electrolytes are one of the most important parts of the battery since they are responsible for the conduction of ions between the electrodes. In this paper, we discuss the different non-flammable electrolytes that were developed recently for safer lithium-ion battery applications.

3D printing is a form of technology that is steadily gaining popularity in library makerspaces, homes, and workspaces around the globe. Several types of 3D printing technologies and materials are available, but most common 3D printers use plastic filament for printing objects. Several research articles report that industrial-sized 3D printers emit harmful ultrafine particles (UFPs)

Globally Harmonized System (GHS) of Classification and Labelling of Chemicals is now universally accepted to communicate the hazards of a chemical. Occupational Safety and Health Administration (OSHA) adopted the GHS system under the Hazard Communication Standard (HCS) in June 2016. In the course of implementation of the GHS, we need to educate our research community, specially new undergraduate and graduate students and provide them with the most recent knowledge of the chemicals, labels, hazards and the ways to protect themselves and their surroundings from the dangers associated with the chemicals. In this paper, we discuss the basics of OSHA hazard communication, GHS system classification, chemical labeling, new hazard pictograms and sections of safety data sheet (SDS) for our students and researchers in an easy to understand format. It is the hope that this publication will benefit the students to understand chemical hazards, to read safety information and to protect themselves when using these materials.
