A one-step pyrolysis process was introduced for higher heatresistant sorbents and zero wastewater generating. The carbonized melamine-formaldehyde sponges (CMSs) improved heat tolerance (the maximum surface temperature = 400 °C) in air and ensued 14% increase of the oil sorption speed. Ultimately, 1 kg of CMSs could achieve continuously absorption speed of 690 kg·h–1 for viscous crude oil.

A semiconducting-metallic phase transition in WSe2 is realized via in situ cesium functionalization. Through spatially controlling cesium doping region, an Ohmic hetero-phase homojunction WSe2 transistor with high current on/off ratio ~ 109 and low subthreshold swing ~ 61 mV/dec is realized. Moreover, homogeneous WSe2 inverter with recorded high gain ~ 270 is achieved.

The tuned 0.50Fe-Bi2WO6 catalyst achieved an ultrahigh NH3 yield rate of 289 μg·h−1·mgcat−1 at −0.75V vs. RHE. The key of the outstanding nitrogen reduction reaction (NRR) behaviors is effectively suppressed hydrogen evolution reaction (HER) and the synergy between Bi and Fe, which can significantly regulate the electron distribution and improve the electron transport.

The power conversion efficiency (PCE) of solid-state fiber-shaped dye-sensitized solar cells with silver-embedded SiO2 nanoparticles reaches 5.38%, which is comparable to the reference (3.98%). And the PCEs remain at 95% between –16.9 to 91.7 °C, indicating the operational stability of solid-state fiber-shaped dye-sensitized solar cells (SS-FDSSCs) within this temperature range.

Non-invasive method was used to deliver L-DOPA-loaded sub- 50 nm nanoparticles to the brain via brain–lymphatic vasculature to bypass the blood–brain barrier. This hydrogen bond-based delivery system between L-DOPA and TA/PVA was prepared via flash nanocomplexation (FNC) method in a one-step, aqueous phase, continuous, and scalable manner. Pharmacodynamics analysis on reserpine-induced Parkinson’s disease (PD) rat model demonstrated the levels of dopamine and tyrosine hydroxylase, which indicate the dopaminergic neuron functions, were increased by 2- and 4-fold respectively, compared to the model groups. Movement disorders and cerebral oxidative stress of the rats were significantly improved without acute toxicity to the major organs, indicating this effective delivery of biocompatible uniform TA/PVA/L-DOPA nanoparticles via brain–lymphatic vasculature holds high clinical translation potential for the treatment of the PD.
