A bottlebrush polymer from Northeastern carries its own tissue-targeting sequence for oligonucleotide drugs

Northeastern's Ke Zhang reports a bottlebrush polymer with a built-in sequence meant to steer oligonucleotide drugs to particular tissues. "Knowing what gene to target is only part of the problem," Zhang said, and delivery to the right cells is the rest.

A metal-organic framework coat lets mitochondria keep producing energy, an Italian team reports

Researchers at Politecnico di Milano and the Besta institute coated mitochondria with a metal-organic framework that left energy production running. Whether coated mitochondria beat bare ones in transplantation is still unproven, according to the release.

Controlling local pH at the electrode lifted desired product from 16% to 97% in an electrosynthesis

Seoul National University researchers raised the desired product share from about 16% to 97% by controlling acidity near electrodes. The route uses oxygen and electricity instead of added peroxides, and the figures come from the university's own summary.

Five-lanthanoid oxide catalyst holds steady methane coupling yield for 240 hours at 600C

Institute of Science Tokyo researchers report a five-lanthanoid oxide catalyst that kept its methane-to-C2 yield steady for 240 hours at 600C. The run was about 200C cooler than conventional catalysts operate, and its durability was measured against the oxides of its own five elements.

Tokyo and Glasgow researchers read electron spins inside a metal-organic framework using light

Researchers in Tokyo and Glasgow used light to read electron spins inside a metal-organic framework, the first such measurement in this porous material. No chemical has been detected with it yet, and the team says the signal needs to get stronger and work at more practical temperatures before sensors can follow.

Max Planck and London chemists use light to make hydrogen atoms for metal-free reductions

Max Planck, UCL and Imperial College chemists used light to make single hydrogen atoms that reduce organic molecules without metals. The mild route puts a species long considered too reactive to handle within reach of synthetic chemists, if yields and substrate range support the team's claim.

Real-time oxygen tracking shows hematite photocurrent overstates water splitting at low currents

Imperial College London researchers measuring oxygen live found hematite converts about 80% of charge to oxygen only once surface charge builds. At lower currents much of it feeds competing surface reactions, so current alone overstates the oxygen.

Lattice spacing sorts magnetic order in gold-based Tsai alloys more cleanly than electron count

Japanese chemists say lattice spacing, with cutoffs at 14.62 and 14.72 angstroms, sorts gold-alloy magnetism better than electron count. That gives chemists looking for new magnetic quasicrystals one measurable target, as long as a new alloy's spacing can be predicted from its composition.

Oregon State chemists make hydrogen from water using a sulfur bond that breaks in light

Oregon State chemists report a framework, BVR-19, that makes hydrogen from water in light with no added expensive metal catalyst. Without a reported rate or efficiency, its bearing on green hydrogen's roughly $5-a-kilogram price is still untested.

Seoul engineers steer pH beside the electrode to make plastic feedstocks at 97% selectivity

Jaeyune Ryu's team at Seoul National University raised selectivity for lactones and epoxides from about 16% to 97% by redesigning the reactor around local pH. Its levers were electrode spacing and electrolyte flow, so cell shape now counts alongside catalyst choice in oxygen-driven oxidation.

Texas A&M simulations find ions ease electron hopping in a zinc framework material

Texas A&M simulations show that ions inside a zinc-based metal-organic framework make it easier for electrons to move through the material. The coupling matters for adaptive, neuron-like analog hardware, but the study maps a mechanism in one material and builds no device.

Yokohama chemists hold cobalt between metal and oxide to hydrogenate pyridine with electricity

Yokohama National University chemists converted pyridine to piperidine at over 99% yield with a cobalt catalyst kept between metal and oxide. That state drifts during electrolysis, so the balance depends on how the cell is run as well as on how the catalyst is made.

Oregon State's BVR-19 framework uses a light-broken sulfur bond to make hydrogen from water

Oregon State researchers report in JACS that BVR-19, a metal-organic framework, makes hydrogen from water under light without an added metal catalyst. The work gives chemists design rules for solar hydrogen, but whether it can make the fuel cheaper depends on production rates and lifetimes.

Chonnam chemists put dichloromethane to work as an amide coupling reagent

Chonnam National University chemists used dichloromethane as an amide coupling reagent, making more than 20 grams of the drug moclobemide at over 99% purity. The open test is whether using up a chlorinated solvent as a reagent leaves less waste than the coupling reagents it would replace.

Dye-coated nanoparticles turn low-cost infrared laser light into a green sensing signal

A University of Toronto team layered ytterbium and erbium so energy moves one way through the particle. The payoff they claim is trace-chemical sensing driven by the kind of near-infrared laser that costs very little.

Kyoto chemists tune a porous liquid's viscosity 170-million-fold from the cage surface alone

The pore volume stayed put while the flow behaviour moved by a factor of 170 million, which is the trade-off that has held these gas-capture fluids back. A process engineer still can't size a loop from what the paper reports, since no capacity figure appears yet.
