Isomerization

By Milica Folić, Product Line Director | Clean Fuels & Chemicals, Topsoe and  Maria Jesus Lorences Perez, Senior Product Line Director | Hydrotreating Catalyst, Topsoe Special to The Digest For over a century, refineries have mastered the art of processing fossil fuels. However, the emerging field of converting renewable feedstocks into transportation fuels, such as […]

Researchers led by Prof. Wang Lei from the Institute of Biophysics of the Chinese Academy of Science (CAS) and their collaborators have identified the direct target of vinigrol as protein disulfide isomerase (PDI) on the cell membrane. Vinigrol activates ADAM17 protease by inhibiting PDI, and then leads to the shedding of immune receptors TNFR1, thereby antagonizing the TNF-α signaling.

Like the neurons firing in human brains, bacteria use electricity to communicate and respond to environmental cues. Now, researchers have discovered a way to control this electrical signaling in bacteria, to better understand resistance to antibiotics.

Researchers led by Prof. Zahng Tao at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has synthesized two novel vinylene-linked two-dimensional covalent organic frameworks (v-2D-COFs) with isomeric structures via benzobisoxazole-mediated aldol polycondensation, showing distinct photocatalytic properties. The study was published in Journal of the American…

Nonoxidative coupling of methane (NOCM) exhibits promising prospect in that it affords value-added hydrocarbons and hydrogen with high atom economy. However, the challenge remains in methane's direct, selective conversion to more valuable hydrocarbons like olefins.

Researchers have revealed the impact of native lipids on rhodopsin signaling and regeneration, which may usher in a new paradigm for discovery of drugs that target G protein-coupled receptors (GPCRs).

Conventional silicon-based transistors, which sit at the heart of every computer, are fast approaching the limit of miniaturisation. Here, Meng et al demonstrate a field-effect transistor composed of a single rutheniumdiarylethene molecule with large on/off ratio.

Researchers from the Wendlandt Lab at MIT have developed a new method for positional control over alkene isomerization, using a dual catalyst system and energy from light to make possible transformations that were previously inaccessible.

Many bacteria and unicellular algae have light-driven pumps in their cell membranes: proteins that change shape when exposed to photons such that they can transport charged atoms in or out of the cell. Thanks to these pumps, their unicellular owners can adjust to the environment's pH value or salinity.

Pathogens hijack host cell functions by expressing or secreting effector proteins, creating environments conducive to their survival and reproduction. These pathogenic microorganisms—including eukaryotic parasites, prokaryotic bacteria, and viruses—express effector proteins that function as their "ammunition depot."

Azobenzenes are incredibly versatile and have many potential uses, such as in making tiny machines and improving technology as well as making light controllable drugs. This molecule can switch between two different forms by light. However, the two forms are in equilibrium, which means that a mixture present that prevents optimal use for applications.

Doping a liquid crystal with azobenzene molecules can induce reversible changes in its thermal conductivity under light irradiation. These findings have been reported in a new collaboration between the Center for Research in Biological Chemistry and Molecular Materials (CiQUS) groups and is now featured on the cover of the Journal of Materials Chemistry C.

Graduate student Colin Kim had been making good progress on a scientific puzzle that had fascinated him since he joined Whitehead Institute Member Jing-Ke Weng's lab, trying to understand how coumarin synthase (COSY), an enzyme that plants use to make agriculturally and medicinally important molecules called coumarins, does its job.

A team of researchers at the Chinese Academy of Sciences, working with a colleague from the State University of New Jersey, has developed a gel-based code-hiding system that uses combinations of water, light and heat to hide and reveal hidden codes. In their paper published in the journal Science Advances, the group describes how their gel is made and the possible uses for it.

Direct hydrogenation of CO2 into liquid fuels can mitigate CO2 emissions and reduce the rapid depletion of fossil fuels. Here, the authors show an iron-based multifunctional catalyst that converts CO2to gasoline with high selectivity due to synergistic cooperation of multiple catalytic active sites.

Propylene is one of the most important petrochemical raw materials, ranging second after ethylene. To meet the ever-increasing demand, alternative technologies for propylene production are in urgent need, among which the propane dehydrogenation (PDH) has been considered as the most promising one.

Linear alcohols, as an important class of chemical products, are indispensable in the production of food, pharmaceuticals, plasticizers, and lubricants. Direct conversion of readily available alkenes into high-value alcohols is important but challenging in both organic synthesis and industry.

Polycyclic aromatic hydrocarbons (PAHs) are a type of organic molecule that carry fused rings made of the chemical benzene. Scientists believe that PAHs are responsible for chemical processes that eventually lead to soot and other carbonaceous nanoparticles on Earth and around and between the stars in deep space. On Earth, PAHs form in part because of the incomplete combustion of coal, oil, and other substances and…
