The current paper describes the performance of a commercial-scale (20,000 tpa) demonstration facility of the DiCOM process, a biological treatment for the organic fraction of municipal solid waste (OFMSW). The 21-d process combines aerobic composting and high-solids (30%DM), thermophilic (55 °C) anaerobic digestion (AD), within a single vessel. Mechanically sorted OFMSW, derived from mixed household MSW (324 t), was exposed to sequential aerobic/anaerobic/aerobic treatment. The AD, initiated by adding anaerobic inoculum from a previous trial, was stable (without pH intervention) and the onset of methanogenesis, rapid (<3 h). Volatile fatty acids formed during AD (including propionate) were exhausted prior to reuse of the inoculum. As measured by an electron flux from solids to gaseous end-products, AD accounted for the greatest portion of solids degradation (86%=160 m(3)CH(4)/drytOFMSW). However, unlike laboratory trials, limited degradation occurred during initial aerobic treatment. The discharged solids were classified as a composted soil conditioner.

Enzymatic DNA synthesis, using stepwise nucleotide addition catalyzed by template-independent polymerases, promises higher efficiency, quality, and sustainability than today's industry-standard phosphoramidite-based processes. We report the directed evolution of a terminal deoxynucleotidyl transferase that uses 3'-phosphate-blocked 2'-deoxynucleoside triphosphates (dNTPs) to control the polymerization reaction. Over 32 iterative rounds of laboratory evolution, 80 amino acid substitutions-constituting ∼20% of the coding protein sequence-were introduced.

Article Synopsis
- NaFeMn(PO)(PO) shows great potential for commercial use due to its higher energy density than NaFe(PO)(PO), but faces issues like impurities and sodium movement problems.
- Researchers investigated these failure mechanisms and found that they stem mostly from element segregation, Na/Mn defects, and blocked sodium channels.
- They proposed a solution using nonhomogeneous Mg doping, which improved the material's performance significantly, resulting in a new cathode with better voltage, energy density, and a much longer lifespan for sodium-ion batteries.

A digital twin of lyophilization units was developed to facilitate the scale-up of the lyophilization process from the laboratory to the commercial scale. Our focus was on ensuring successful technology transfer for manufacture of high-quality drug products. Traditionally, lyophilization models have been specific either to the equipment or to the vial.

Piscine orthoreovirus (PRV) is a virus that is widely distributed among global aquaculture populations of salmonid species. The coho salmon (Oncorhynchus kisutch) is a species of increasing productive and economic importance in Chile. The presence of PRV has generated concern about its impact on the health and welfare of this species.

Electrically rechargeable zinc-air batteries (ZABs) are emerging as promising energy storage devices in the post-lithium era, leveraging the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) at the air cathodes. Efficient bifunctional oxygen electrocatalysts, capable of catalyzing both the ORR and OER, are essential for the operation of rechargeable ZABs. Traditional Pt- and RuO/IrO-based catalysts are not ideal, as they lack sufficient bifunctional ORR and OER activity, exhibit limited long-term durability, require high overpotentials and are expensive.
