This work reports an easy soft-template method to precisely engineer porous architectures of quaternary PdCuBP mesoporous nanospheres (MSs). It is demonstrated that PdCuBP MSs with three-dimensional dendritic mesopores disclose much better electrocatalytic performance toward ethanol oxidation electrocatalysis, due to more active sites, optimum electron/mass transfers, and better anti-poisoning ability.

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.

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.
