Fast-charging damages electric car batteries

Just 25 industry-standard fast charging cycles can ruin a car's batteries

16-Mar-2020

Commercial fast-charging stations subject electric car batteries to high temperatures and high resistance that can cause them to crack, leak, and lose their storage capacity, write engineers at the University of California, Riverside in a new study published in Energy Storage. To remedy this, the ...

A possible end to 'forever' chemicals

Excess electrons could help break the strong chemical bonds in products that contaminate water supplies

13-Mar-2020

Synthetic chemicals known as per- and polyfluoroalkyls, or PFAS, contain bonds between carbon and fluorine atoms considered the strongest in organic chemistry. Unfortunately, the widespread use of these nonbiodegradable products since the 1940s has contaminated many water supplies across ...

Can I mix those chemicals? There's an app for that!

New technology can find the safest way to store and dispose of reactive chemicals

27-Jan-2020

Improperly mixed chemicals cause a shocking number of fires, explosions, and injuries in laboratories, businesses, and homes each year. A new open source computer program called ChemStor developed by engineers at the University of California, Riverside, can prevent these dangerous situations by ...

Fiber-optic probe can see molecular bonds

Pointing the new nanoscopy tool like a Harry Potter wand reveals a high-resolution image of molecules

12-Jun-2019

In "Avengers: Endgame," Tony Stark warned Scott Lang that sending him into the quantum realm and bringing him back would be a "billion-to-one cosmic fluke." In reality, shrinking a light beam to a nanometer-sized point to spy on quantum-scale light-matter interactions and retrieving the ...

Partitioning of Porous Materials

Highly resorptive MOFs can be constructed by a foresighted combination of two different synthetic principles

02-May-2019

Gases and pollutants can be filtered from air and liquids by means of porous, crystalline materials, such as metal–organic frameworks (MOFs). To further partition these pores and enhance their sorption capacity, a team of scientists have developed a fast and versatile two-in-one synthetic ...

Imaging conducting edges in a promising 2D material

Study on monolayer tungsten ditelluride could lead to more energy-efficient electronic devices

12-Feb-2019

A research team comprised of scientists at the University of California, Riverside, and the University of Washington has for the first time directly imaged "edge conduction" in monolayer tungsten ditelluride, or WTe2, a newly discovered 2-D topological insulator and quantum material. The research ...

Musical sensor shows bad medicine plays false note

Inspired by a musical instrument, the simple sensor can be constructed from common materials and used to detect adulterated or counterfeit drugs

17-Sep-2018

What if a single musical note could mean the difference between life and death? A new sensor based on a 3,000 year old African musical instrument can be used to identify substances, including a poisonous chemical sometimes mistakenly added to medicines. The mbira sensor, which can be constructed ...

A better way to control crystal vibrations

23-May-2018

The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations travel through the crystalline structure determine fundamental properties of the material. For ...

Advancement in spintronics technology

06-Feb-2018

Engineers at the University of California, Riverside, have reported advances in so-called "spintronic" devices that will help lead to a new technology for computing and data storage. They have developed methods to detect signals from spintronic components made of low-cost metals and silicon, ...

Giant charge reversal observed for the first time

14-Jul-2017

Charged surfaces submerged in an electrolyte solution can sometimes become oppositely charged. This nonintuitive phenomenon, known as charge inversion, happens when excess counter ions adsorb, or adhere, to the surface. It can occur in a number of chemical and biological settings. In certain ...
