High-throughput and sustainable B vitamins analysis in nutritional supplements, vegetables, and fruits via 2D carbon microfiber fractionation system coupled with mass spectrometry.

B vitamins are essential for energy metabolism, nervous health, blood production, and the immune system. Their quantification in nutritional supplements and food is mandatory to manage a correct daily intake and dosage. In this study, a fast and sustainable method for the analysis of 8 B vitamins (VB, VB, VB, nicotinamide, VB, VB, VB, VB) in real samples using a 2D-carbon microfiber fractionation system combined with a triple quadrupole mass spectrometer (2DμCFs-QqQ-MS/MS) is presented.

Vertical Gradient of Nitryl Chloride and Implications for Atmospheric Photochemistry in Pearl River Delta, China, during Wintertime.

Nitryl chloride (ClNO) is a key precursor of chlorine radicals, influencing atmospheric oxidation and secondary pollutants formation. Few studies have examined the ClNO chemistry from the perspective of the planetary boundary layer. Here, we conducted a vertically resolved investigation of ClNO at six heights (ranging from 5 to 335 m) on a 356 m tower in the Pearl River Delta, China, during winter 2021.

Mechanically robust and stretchable organic solar cells plasticized by small-molecule acceptors.

Emerging wearable devices would benefit from integrating ductile photovoltaic light-harvesting power sources. In this work, we report a small-molecule acceptor (SMA), also known as a non-fullerene acceptor (NFA), designed for stretchable organic solar cell (-OSC) blends with large mechanical compliance and performance. Blends of the organosilane-functionalized SMA BTP-Si4 with the polymer donor PNTB6-Cl achieved a power conversion efficiency (PCE) of >16% and ultimate strain (ε) of >95%.

Unveiling the role of NiFeM hydroxide (M = Pt, Ru, Ir, Rh) cocatalysts for robust H production in photocatalytic water splitting.

In this study, the NiFe-LDH doped with different Pt group metals (Pt, Ru, Ir, Rh) was prepared as a cocatalyst for photocatalytic H production over g-CN. It is found that the doped NiFe-LDH loaded g-CN generally displays higher photocatalytic activity than the raw NiFe-LDH modified one, where the NiFeRu-LDH loaded g-CN shows the optimal H evolution rate of 77.4 μmol h, about 5.

Gene mutation, clinical characteristics and pathology in resectable lung adenocarcinoma.

Objective: With the wide use of CT scan in clinical practice, more lung cancer was diagnosed in resectable stage. Pathological examination and genetic testing have become a routine procedure for lung adenocarcinoma following radical resection. This study analyzed special pathological components and gene mutations to explore their relationship with clinical characteristics and overall survival.
