Direct power generation from methylcyclohexane using solid oxide fuel cells      (via sciencedaily.com)     Original source 

Methylcyclohexane is very promising as a hydrogen carrier that can safely and efficiently transport and store hydrogen. However, the dehydrogenation process using catalysts has issues due to its durability and large energy loss. Recently, researchers have succeeded in using solid oxide fuel cells to generate electricity directly from methylcyclohexane and recover toluene for reuse. This research is expected to not only reduce energy requirements but also explore new chemical synthesis by fuel cells.

Public support hydrogen and biofuels to decarbonize global shipping      (via sciencedaily.com)     Original source 

New research into public attitudes towards alternative shipping fuels shows public backing for biofuel and hydrogen. The study also found that nuclear was preferred to the heavy fuel oil (HFO) currently used in the global shipping industry, although both were perceived negatively. Ammonia had the least public support.

First detection of crucial carbon molecule      (via sciencedaily.com)     Original source 

Scientists detect a new carbon compound in space for the first time. Known as methyl cation (pronounced cat-eye-on) (CH3+), the molecule is important because it aids the formation of more complex carbon-based molecules. Methyl cation was detected in a young star system, with a protoplanetary disk, known as d203-506, which is located about 1,350 light-years away in the Orion Nebula.

Towards efficient lithium--air batteries with solution plasma-based synthesis of perovskite hydroxide catalysts      (via sciencedaily.com)     Original source 

CoSn(OH)6 (CSO) is an effective oxygen evolution reaction (OER) catalyst, necessary for developing next-generation lithium -- air batteries. However, current methods of synthesizing CSO are complicated and slow. Recently, an international research team synthesized CSO in a single step within 20 minutes using solution plasma to generate CSO nanocrystals with excellent OER catalytic properties. Their findings could boost the manufacturing of high energy density batteries.

Surprise! Weaker bonds can make polymers stronger      (via sciencedaily.com)     Original source 

Chemists discovered a new way to make polymers stronger: introduce a few weaker bonds into the material. Working with polyacrylate elastomers, they could increase the materials' resistance to tearing up to tenfold by using a weaker type of crosslinker to join some of the polymer building blocks.

Biodegradable gel shows promise for cartilage regeneration      (via sciencedaily.com)     Original source 

A gel that combines both stiffness and toughness is a step forward in the bid to create biodegradable implants for joint injuries, according to new research. Mimicking articular cartilage, found in our knee and hip joints, is challenging. This cartilage is key to smooth joint movement, and damage to it can cause pain, reduce function, and lead to arthritis. One potential solution is to implant artificial scaffolds made of proteins that help the cartilage regenerate itself as the scaffold biodegrades. How well the cartilage regenerates is linked to how well a scaffold can mimic the biological properties of cartilage, and to date, researchers have struggled to combine the seemingly incompatible properties of stiffness and toughness. Now, new research outlines a method to marry these properties in a biodegradable gel.

A 'pinch' of mineral salts helps the noncaloric sweeteners go down      (via sciencedaily.com)     Original source 

Perfect noncaloric replacements for sugar and high fructose corn syrup just don't exist yet. For example, some alternatives have a lingering sweet aftertaste and lack a sugar-like mouthfeel, leaving some consumers unsatisfied. Now, researchers propose adding blends of nutritionally important mineral salts to make noncaloric sweeteners seem more like the real thing. Taste-testers indicated that these blends gave zero- and low-calorie drinks a better flavor.
