The reduction of fullerene (C) with sodium dispersion in the presence of an excess amount of dipropyl sulfate was found to yield highly propylated fullerene, C(CH) (max. = 24), and C(CH) was predominantly generated as determined by mass spectroscopy.

As one of the core parts of the Internet-of-things (IOTs), multimodal sensors have exhibited great advantages in fields such as human-machine interaction, electronic skin, and environmental monitoring. However, current multimodal sensors substantially introduce a bloated equipment architecture and a complicated decoupling mechanism. In this work we propose a multimodal fusion sensing platform based on a power-dependent piecewise linear decoupling mechanism, allowing four parameters to be perceived and decoded from the passive wireless single component, which greatly broadens the configurable freedom of a sensor in the IOT.

This study describes a microfluidic thread-based analytical device (μTAD) capable of in situ mass spectrometric analysis for continuous flow reaction monitoring. Organic reaction screening is foundational to drug discovery. Microfluidic devices are of special interest here because they provide continuous reaction monitoring with advantages such as the use of smaller reagent volumes and short analysis times.

Persistent oxidative stress following bone defects significantly impedes the repair of bone tissue. Designing an antioxidative hydrogel with a suitable mechanical strength can help alter the local microenvironment and promote bone defect healing. In this work, α-lipoic acid (LA), a natural antioxidant small molecule, was chemically cross-linked with lipoic acid-functionalized poly(ethylene glycol) (PEG, = 6k or 10k) in sodium bicarbonate solution, to prepare LA-PEG hydrogels (LP, = 6k or 10k).

High-performance boiling surfaces are in great demand for efficient cooling of high-heat-flux devices. Although various micro-/nano-structured surfaces have been engineered toward higher surface wettability and wickability for enhanced boiling, the design and fabrication of surface structures for realizing both high critical heat flux (CHF) and high heat transfer coefficient (HTC) remain a key challenge. Here, a novel "electrode-transpose" all-electrochemical strategy is proposed to create superhydrophilic microporous surfaces with higher dendrites and larger pores by simply adding an electrochemical etching step prior to the multiple electrochemical deposition steps.
