Functional polymer materials containing heavy group‐14 elements focusing on germanium and tin

open access: yesSmart Molecules, Volume 4, Issue 1, March 2026.
The synthesis, functions, and applications of the polymers containing heavy group 14 elements focusing on germanium and tin are outlined. Owing to their large atomic radii and weak binding energies, the polymers show unique properties: chromism, luminescence, carrier mobility, and reactivity to produce radials and higher coordinated states.

Toward Decarbonization of the Titanium Industry via Hydrogen Plasma Smelting Reduction

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
Hydrogen plasma smelting reduction enables direct, zero‐carbon conversion of low‐grade ilmenite into steel‐grade iron and a titania‐rich precursor for pigment production. The single‐step process merges smelting and refining, sharply lowers silica content, and offers a breakthrough path for sustainable, high‐value extraction from abundant mineral sands.

Immobilization, Regiospecificity Characterization and Application of Aspergillus oryzae Lipase in the Enzymatic Synthesis of the Structured Lipid 1,3-Dioleoyl-2-Palmitoylglycerol. [PDF]

open access: yesPLoS ONE, 2015
The enzymatic synthesis of 1,3-dioleoyl-2-palmitoylglycerol (OPO), one of the main components of human milk fats, has been hindered by the relatively high cost of sn-1,3-specific lipases and the deficiency in biocatalyst stability.

Recycling of Polyurethane Waste: Facile Hydrothermal Conversion Using Acidic and Basic Additives

open access: yesChemSusChem, Volume 19, Issue 1, January 2026.
Ethylenediamine efficiently catalyses the hydrothermal recycling of polyurethane (PU) into monomers. The NH functional groups promote carbamic acid decomposition via zwitterion interactions, outperforming inorganic acids and bases, and enabling selective depolymerisation of PU under mild conditions for circular chemical utilisation.
