Hollow porphyrinic nanospheres

An extensive internal void enables a secure encapsulation, delivery, and storage of guest molecules as large as 4 nanometers

11-Nov-2020

Famous Catalan architect Antoni Gaudí once said, "Anything created by human beings is already in the great book of nature." Among different man-made architectures and art, spherical structures and shapes have been the most fantastical geometrical form that fascinated the figments of the human ...

'Transparent solar cells' can take us towards a new era of personalized energy

Scientists design novel transparent solar cells using thin silicon films, with efficient power generation

04-Nov-2020

Today, the imminent climate change crisis demands a shift from conventionally used fossil fuels to efficient sources of green energy. This has led to researchers looking into the concept of "personalized energy," which would make on-site energy generation possible. For example, solar cells could ...

Charging electric cars up to 90% in 6 minutes

Research team uncovers a new Li-ion battery electrode material that can achieve high-energy density and high power capability per volume without reducing particle size

27-Oct-2020

With Telsa in the lead, the electric vehicle market is growing around the world. Unlike conventional cars that use internal combustion engines, electric cars are solely powered by lithium ion batteries, so the battery performance defines the car's overall performance. However, slow charging times ...

High-performance single-atom catalysts for high-temperature fuel cells

Catalysts are stable at 700 degrees Celsius and expected to stimulate the commercialization of next-gen reversible fuel cells

29-Sep-2020

Unlike secondary batteries that need to be recharged, fuel cells are a type of eco-friendly power generation systems that produce electricity directly from electrochemical reactions using hydrogen as fuel and oxygen as oxidant. There are various types of fuel cells, differing in operating ...

Smart AI makes all kinds of shapes on its own

Artificial neural network system recommends plastic molding process conditions

20-Aug-2020

Plastic is light, cheap, and can be made into any shape if heated, making it a "gift from the 20th-century god." The key is to maintain its uniform quality but its sensitivity to process conditions makes processing autonomy difficult. It also takes long to change the process once it is set and ...

Seeing chemical reactions with music

Audible sound enables chemical coloring and the coexistence of different chemical reactions in a solution

12-Aug-2020

Albert Einstein once said, "I see my life in terms of music." Perhaps inspired by his words, scientists at the Center for Self-assembly and Complexity (CSC), within the Institute for Basic Science (IBS, South Korea) now see chemical reactions in the presence of music. The IBS research team has ...

A novel strategy to generate useful chiral compounds

Newly designed ligands for a catalytic reaction to synthesize drugs and useful compounds

01-Jul-2020

Currently, various therapeutic compounds in the market, such as proteins, enzymes, and amino acids, are "chiral compounds"--molecules with two structures that are "mirror" images of each other but cannot be superimposed. Although the two variants of the molecule, also called "enantiomers," are ...

Preventing lithium loss for high-capacity lithium-ion batteries

A novel pretreatment strategy resolves a long-standing issue of silicon anode materials

23-Jun-2020

A team of Korean researchers has developed a processing technology for maximizing energy densities of high-capacity batteries. The joint research team, which consists of Dr. Lee, Minah of the Center for Energy Storage Research and Dr. Hong, Jihyun of the Center for Energy Materials Research, both ...
