In the study, water-derived hydroxyl-radical formation was identified as the rate-determining step in polyethylene oxidation, with a kH/kD isotope effect of 7.CAUSALSupported
The study achieved complete polyethylene conversion with nearly 69% selectivity to short-chain diacids and demonstrated scaling up to 300 g for mixed commercial plastics.QUANTITATIVESupported
The study reported a catalyst-free microdroplet-interface strategy using in situ hydroxyl radicals to oxidatively cleave diverse waste plastics into carboxylic acids under mild conditions.OBSERVATIONALSupported
The reported Li||S2Cl2 chemistry increased average operating voltage from 2.05 to 2.54 V, raised sulfur-specific capacity by 58%, and exceeded 1,700 Wh kg−1 electrode-level specific energy while cycling over 100 cycles.QUANTITATIVESupported
A free-chloride-rich ionic liquid electrolyte enables reversible Li||S2Cl2 battery chemistry that converts Li2S to S2Cl2 through a three-electron sulfur redox process.OBSERVATIONALSupported
At 80 bar, the study measured CU-6 gravimetric methane uptakes of up to 0.67 g g−1 at 273 K and 0.53 g g−1 at 298 K for CU-6-Fe.QUANTITATIVESupported
At 100 bar and 77 K, the study measured total hydrogen uptakes of 17.5 wt% for CU-6-Fe and 15.9 wt% for CU-6-Cr, with volumetric uptakes near 45.4–45.5 g l−1.QUANTITATIVESupported
The study reported CU-6-Fe and CU-6-Cr with an interconnected hierarchical pore system and BET surface areas up to 7,145 m2 g−1.QUANTITATIVESupported
A 98-day river alkalinity-enhancement trial in Norway reported 250 ± 30 tonnes CO2-equivalent of gross carbon dioxide removal after adding 1,480 tonnes of calcite, with no significant increase in most measured adverse water-quality indicators apart from phosphate.QUANTITATIVESupported
The study demonstrated a monolithic perovskite–silicon tandem solar cell with certified power-conversion efficiency of 33.0%.QUANTITATIVESupported
Ambient-air, blade-coated perovskite solar cells in the study reached 26.5% certified power-conversion efficiency, while modules reached 23.2% and cells retained 99.8% of initial efficiency after 1,200 hours of light soaking.QUANTITATIVESupported
The study defines void suppression capability as the product of lithium full-stripping areal capacity and applied current density, and phase-field modelling predicts dendrite growth and cell failure when stripped capacity exceeds 70% of full depletion capacity.CAUSALSupported
In an all-solid-state lithium-anode study, Mg–1 wt% La inoculation increased critical current density/capacity from 1.2 mA cm−2/0.6 mAh cm−2 for LiMg to 2.2 mA cm−2/1.1 mAh cm−2 for LiMgLa, which sustained stable plating/stripping for over 1,200 hours at 0.7 mA cm−2 at room temperature.QUANTITATIVESupported
In a Europe-wide model conditional on green-hydrogen diffusion resembling natural-gas power-plant diffusion, targeting the most central offtakers reduced median policy cost per additional kilogram by 37–41%, while adding a 10% centrality criterion to a hydrogen-bank-style auction improved cost-effectiveness by 13–15%.QUANTITATIVESupported
The reported process couples alkaline seawater electrolysis with low-temperature desalination, using electrolyser waste heat to distill seawater and provide freshwater for electrolysis and external use.OBSERVATIONALSupported
The reported seawater-hydrogen system operated stably for 100 days at 20 kW, producing 3.8 Nm³ h⁻¹ hydrogen and 1.2 kg h⁻¹ freshwater; at 250 kW it produced 48 Nm³ h⁻¹ hydrogen and 31.6 kg h⁻¹ freshwater, with 14.4% higher electrical efficiency than alkaline electrolysis using freshwater alone.QUANTITATIVESupported
In the pre-pandemic 2015–2020 period, existing links in the global rock-phosphate trade network tended to persist while new ties appeared infrequently.OBSERVATIONALSupported
In the pre-pandemic 2015–2020 period, the global rock-phosphate trade network was characterized by low density and reciprocity, small-world and scale-free structure, decentralization, slight disassortativity, and moderate geographic heterophily.OBSERVATIONALSupported
In the reported study, the perovskite solar devices retained 93.3% of their initial efficiency after 1000 hours of maximum-power-point tracking.QUANTITATIVESupported
In the reported study, flexible perovskite solar devices achieved 25.13% efficiency, while a 655.2 cm² submodule achieved 22.60% efficiency (certified 21.07%).QUANTITATIVESupported
In the reported hard-carbon preparation study, reducing carbonization temperature from 1300 °C to 900 °C was associated with 49.7% lower energy consumption and 47.5% lower carbon emissions.QUANTITATIVESupported
In the reported hard-carbon sodium-ion pouch-cell experiment, the cell achieved 208.1 Wh kg−1 specific energy at 1.5–4.3 V based on the entire cell.QUANTITATIVESupported
Roughly $500 billion in additional annual spending on chips, servers, data centres, cooling and power infrastructure is supporting demand for electricians, HVAC specialists and technicians.QUANTITATIVESupported
