Supramolecular hydrogels involved macrocycles have been explored widely in recent years, but it remains challenging to develop hydrogel based on solitary macrocycle with super gelation capability. ...Here, the construction of lantern3
arene-based hydrogel with low critical gelation concentration (0.05 wt%), which can be used for efficient oil-water separation, is reported. The lantern3
arenes self-assemble into hydrogen-bonded organic nanoribbons, which intertwine into entangled fibers to form hydrogel. This hydrogel which exhibits reversible pH-responsiveness characteristics can be coated on stainless-steel mesh by in situ sol-gel transformation. The resultant mesh exhibits excellent oil-water separation efficiency (>99%) and flux (>6 × 10
L m
h
). This lantern3
arene-based hydrogel not only sheds additional light on the gelation mechanisms for supramolecular hydrogels, but also extends the application of macrocycle-based hydrogels as functional interfacial materials.

•We investigate the MADM problems with hesitant triangular fuzzy information.•We develop the definition and operations of the hesitant triangular fuzzy sets.•We develop some hesitant triangular fuzzy ...Einstein aggregation operators.•We utilize these operators to solve the hesitant triangular fuzzy MADM problems.
In this paper, we investigate the multiple attribute decision making (MADM) problems in which attribute values take the form of hesitant triangular fuzzy information. Firstly, definition and some operational laws of hesitant triangular fuzzy elements and score function of hesitant triangular fuzzy elements are introduced. Then, we have developed some hesitant triangular fuzzy aggregation operators based on the Einstein operation: the hesitant triangular fuzzy Einstein weighted averaging (HTFEWA) operator, hesitant triangular fuzzy Einstein weighted geometric (HTFEWG) operator, hesitant triangular fuzzy Einstein ordered weighted averaging (HTFEOWA) operator, hesitant triangular fuzzy Einstein ordered weighted geometric (HTFEOWG) operator, hesitant triangular fuzzy Einstein hybrid average (HTFEHA) operator and hesitant triangular fuzzy Einstein hybrid geometric (HTFEHG) operator. We have applied the hesitant triangular fuzzy Einstein weighted averaging (HTFEWA) operator, hesitant triangular fuzzy Einstein weighted geometric (HTFEWG) operators to multiple attribute decision making with hesitant triangular fuzzy information. Finally an illustrative example has been given to show the developed method.

The oxygen evolution reaction (OER) is central to energy conversion technologies, but the high cost and scarcity of commercial noble metal catalysts limit their widespread application. Natural ...products exhibit great potential in preparing high‐performance electrocatalysts due to their cost‐effectiveness and sustainability. Here, a kind of 1D polymers M‐EA (M═Co, Cu, Ni) for oxygen evolution reaction via the complexation of ellagic acid (EA) with metal ions are reported. It is found that Ni‐EA displays a low overpotential (190 mV at 10 mA cm−2) and an ultralow Tafel slope (28 mV dec−1), with a production cost of only 3.6 × 10−2% of IrO2. Density functional theory investigations reveal the electrocatalytic mechanism of the OER. A rechargeable Zn‐Air battery using Ni‐EA+Pt/C as the air electrode shows a lower charging potential and better cycling stability than the IrO2+Pt/C‐based battery. This work provides a train for the development of state‐of‐the‐art OER catalysts.
This work reports a kind of 1D coordination polymers based on nonprecious metals and natural products, which show an impressive overpotential of 190 mV at 10 mA cm−2 and an ultralow Tafel slope of 28 mV dec−1. The inexpensive and sustainable raw materials can reduce the OER catalyst cost by 4 orders of magnitude.

Background and Aim
Chinese herbal medicine (CHM), as well as Western medicine (WM), is an important cause of drug‐induced liver injury (DILI). However, the differences between CHM and WM as agents ...implicated in liver injury have rarely been reported.
Methods
Overall, 1985 (2.05%) DILI cases were retrospectively collected from the 96 857 patients hospitalized because of liver dysfunction in the 302 Military Hospital between January 2009 and January 2014.
Results
In all the enrolled patients with DILI, CHM was implicated in 563 cases (28.4%), while 870 cases (43.8%) were caused by WM and the remaining patients (27.8%) by the combination of WM and CHM. Polygonum multiflorum was the major implicated CHM. Compared with WM, the cases caused by CHM showed more female (51 vs 71%, P < 0.001) and positive rechallenge (6.1 vs 8.9%, P = 0.046), a much greater proportion of hepatocellular injury (62.2 vs 88.5%, P < 0.001), and a higher mortality (2.8 vs 4.8%, P = 0.042); however, no differences in the rates of chronic DILI and ALF were found (12.9 vs 12.4%, P = 0.807; 7.6 vs 7.6%, P = 0.971). Based on Roussel Uclaf Causality Assessment Method, 75.6% of cases caused by CHM were classified as probable and only 16.6% as highly probable, significantly different from WM (38.4 and 60.3%, all P < 0.001).
Conclusions
The causal relationship between CHM and liver injury is much complex, and the clinical characteristics of DILI caused by CHM differ from those caused by WM.

Macrofungi are well known as mushrooms, which belong mostly to Basidiomycota with a few from Ascomycota, and up to now, around 40,000 species have been described. In people’s lives, macrofungi are ...closely related to our economic activities, especially for food and medicine. “One meat, one vegetable and one mushroom” has become a healthy and fashionable dietary structure, and the global edible mushroom production and cultivating area are steadily rising. On the other hand, a large number of mushroom species and new active components have been found, and have become one of the driving forces of innovation of drugs and health products, especially with the development of biochemistry, enzyme engineering, and genetic engineering. Thus, macrofungi in food, medicine, and other aspects have shown a broad prospect. In this Special Issue, research on new species and related molecular phylogenies, mechanisms of hyphae polar growing and basidiocarp formation, biochemistry of edible and medical mushrooms, and some important scientific questions related to the edible mushroom industry are presented, which also reflect the hot areas of common concern on edible and medicinal fungi.
Two solvent-induced porous hydrogen-bonded organic frameworks have been obtained, and their synthesis, crystal structures, gas sorption behaviours and fluorescence sensing applications have been ...systematically investigated to elucidate the solvent effects on the structures and functionalities of HOFs.
Agaricus bisporus is the most widely cultivated edible mushroom in the world with a only around three hundred years known history of cultivation. Therefore, it represents an ideal organism not only ...to investigate the natural evolutionary history but also the understanding on the evolution going back to the early era of domestication. In this study, we generated the mitochondrial genome sequences of 352 A. bisporus strains and 9 strains from 4 closely related species around the world. The population mitogenomic study revealed all A. bisporus strains can be divided into seven clades, and all domesticated cultivars present only in two of those clades. The molecular dating analysis showed this species origin in Europe on 4.6 Ma and we proposed the main dispersal routes. The detailed mitogenome structure studies showed that the insertion of the plasmid-derived dpo gene caused a long fragment (MIR) inversion, and the distributions of the fragments of dpo gene were strictly in correspondence with these seven clades. Our studies also showed A. bisporus population contains 30 intron distribution patterns (IDPs), while all cultivars contain only two IDPs, which clearly exhibit intron loss compared to the others. Either the loss occurred before or after domestication, that could suggest that the change facilitates their adaptation to the cultivated environment.

The surface layer of Poria cocos (Fu-Ling-Pi, FLP) is commonly used in traditional Chinese medicine and its diuretic effect was confirmed in rat. Ultra performance liquid chromatography/quadrupole ...time-of-flight high-sensitivity mass spectrometry and a novel mass spectrometry(Elevated Energy) data collection technique was employed to investigate metabonomic characteristics of chronic kidney disease (CKD) induced from adenine excess and the protective effects of FLP. Multiple metabolites are detected in the CKD and are correlated with progressive renal injury. Among these biomarkers, lysoPC(18∶0), tetracosahexaenoic acid, lysoPC(18∶2), creatinine, lysoPC (16∶0) and lysoPE(22∶0/0∶0) in the FLP-treated group were completely reversed to levels in the control group which lacked CKD. Combined with biochemistry and histopathology results, the changes in serum metabolites indicate that the perturbations of phospholipids metabolism, energy metabolism and amino acid metabolism are related to adenine-induced CKD and to the interventions of FLP on all the three metabolic pathways. FLP may regulate the metabolism of these biomarkers, especially their efficient utilization within the context of CKD. Furthermore, these biomarkers might serve as characteristics to explain the mechanisms of FLP.
