13.7% efficient graphene/Si heterojunction solar cells with one-step transferred polymer anti-reflection layer for enhanced light absorption and device durability.

Graphene/Silicon (Gr/Si) heterojunction shows great potential as high-efficiency, cost-effective solar cells compared to traditional Si solar cells. However, the high optical loss of c-Si, mainly originating from abrupt change of refractive index at air/Si interface, and the unsatisfactory conductivity of practically prepared graphene layer, still hinder their extensive applications. Herein, we report the performance improved Gr/Si solar cells by depositing a polymathic methacrylate (PMMA) anti-reflection coating (ARC) layer through a one-step transferred method.

TRIM56 Promotes White Adipose Tissue Browning to Attenuate Obesity by Degrading TLE3.

In mammals, the activation of thermogenic adipocytes, such as beige and brown adipocytes, can significantly increase overall energy expenditure, offering a promising strategy to combat metabolic diseases. Despite its considerable potential, the regulatory mechanisms governing this activation remain largely elusive. This study bridges this gap by elucidating that tripartite motif 56 (TRIM56), an E3 ubiquitin ligase, is upregulated in response to cold stimuli, thereby promoting the recruitment of beige adipocytes.

Iron-based materials functionalized with carbon and phosphorus recovered from sludge enhanced the formation of stable minerals to passivate lead and chromium in wastewater and soil.

The bioaccumulation and toxicity of heavy metals are serious threats to human activities and ecological health. The exploitation of environmentally friendly passivated materials is major importance for the remediation of heavy metal contaminated soil. This research developed a new type of environmental functional material with a core-shell structure, which is an iron-based material functionalized with phosphorus and carbon from sludge for heavy metal pollution remediation.

Inhibition of HSP20 Ameliorates Steatotic Liver Disease by Stimulating ERK2-Dependent Autophagy.

HSP20 emerges as a novel regulator of autophagy in the heart. Nonetheless, the detailed function of HSP20 in the liver and its effect on autophagy remain unknown. Here, we observed that HSP20 expression is increased in liver tissues from mice and patients with metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease.

PRMT4 Facilitates White Adipose Tissue Browning and Thermogenesis by Methylating PPARγ.

Unlabelled: Obesity is a global health threat, and the induction of white adipose tissue (WAT) browning presents a promising therapeutic method for it. Recent publications revealed the essential role of protein arginine methyltransferase 4 (PRMT4) in lipid metabolism and adipogenesis, but its involvement in WAT browning has not been investigated. Our initial studies found that the expression of PRMT4 in adipocytes was upregulated in cold-induced WAT browning but downregulated in obesity.

Novel adipokine asprosin modulates browning and adipogenesis in white adipose tissue.

Obesity is an increasingly serious epidemic worldwide characterized by an increase in the number and size of adipocytes. Adipose tissue maintains the balance between lipid storage and energy utilization. Therefore, adipose metabolism is of great significance for the prevention, treatment and intervention of obesity.

Bis(ethanamidinium) (1,10-phen-an-thro-line-2,9-dicarboxyl-ato)manganate(II) hepta-hydrate.

In the title complex, (C2H7N2)2[Mn(C14H6N2O4)2]·7H2O, the Mn(II) atom is coordinated by four N atoms and four O atoms from two 1,10-phenanthroline-2,9-dicarboxyl-ate ligands in a distorted dodeca-hedral geometry. The double negative charge is balanced by two ethanamidinium cations. A three-dimensional supra-molecular structure is formed through N-H⋯O and O-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.

Objective: To study the extraction system of hirudin emulsion liquid membrane with the Poecilobdella manillensis as raw material, di-(2-ethylhexyl) phosphate (D2EHPA) as carrier, Span 80 as emulsifier, octane and D2EHPA mixed to constitute membrane solution, diluted HCl solutions as internal aqueous phase.

Method: Using the orthogonal experiment to optimize the extraction conditions of hirudin reference substance such as membrane phase, internal aqueous phase volume ratio (MIPVR), external aqueous phase pH, internal aqueous phase pH, mobile carrier concentration and so on, and then using hirudin crude extracts to do purifying experiment, and gaining experimental samples.

Result: The optimal conditions of hirudin extraction were as follows: MIPVR 10: 3, internal aqueous phase pH 2.

Two novel Dy8 and Dy11 clusters with cubane [Dy4(μ3-OH)4]8+ units exhibiting slow magnetic relaxation behaviour.

Two unique octa- and hendeca-nuclear dysprosium(III) clusters incorporating [Dy(4)(μ(3)-OH)(4)](8+) cubane units have been synthesized with the 1,10-phenanthroline-2,9-dicarbaldehyde dioxime (H(2)phendox) ligand and DyCl(3)·6H(2)O or Dy(OAc)(3)·4H(2)O. They are [Dy(8)(OH)(8)(phendox)(6)(H(2)O)(8)]Cl(2)(OH)(2)·18H(2)O·18MeOH (1) and [Dy(11)(OH)(11)(phendox)(6)(phenda)(3)(OAc)(3)](OH)·40H(2)O·7MeOH (2). Adjacent Dy(8) in 1 or Dy(11) in 2 motifs are packed by off-set π-π interactions of the aromatic rings on phendox(2-) to generate a 3D supramolecular architecture in the honeycomb topology and with 1D or 3D channels along the c-axis.

Synthesis, structures, adsorption behaviour and magnetic properties of a new family of polynuclear iron clusters.

Solvothermal reactions of 1,10-phenanthroline-2,9-dicarbaldehyde dioxime (H(2)phendox) with FeCl(3)·6H(2)O or FeBr(3) under solvothermal conditions yielded two trinuclear iron(III) clusters [Fe(III)(3)(mu(3)-O)(phendox)(3)]X·14H(2)O (X = Cl 1·14H(2)O, Br 2·14H(2)O) and three hexanuclear iron(III) and iron(II) clusters, [Fe(III)(6)(mu(4)-O)(2)(MeO)(6)X(4)(phendox)(2)]·MeOH (X = Cl , Br 4) and (H(3)O)[Fe(II)(6)(mu(6)-Cl)(phenda)(6)]·6H(2)O (5·6H(2)O). The phendox(2-) ligand is very useful in constructing magnetically active and stable high-nuclearity metal clusters in that the phenanthroline rings and the oxime nitrogen atoms grasp the metal ions tightly while the two oxygen atoms on the oximates can link other metal centres in the shortest pairwise magnetic exchange pathway. Adjacent Fe(3)(mu(3)-O)(phendox)(3)(+) motifs in 1 and 2 are packed by off-set pi-pi interactions of the aromatic rings on phendox(2-) to generate a 3D supramolecular architecture in the honeycomb topology and with 1D hexagonal channels in the dimension of 13 x 13 Å along the c-axis.

Aqua-chlorido(4-methyl-benzoato-κO)(1,10-phenanthroline-κN,N')copper(II).

In the title mononuclear complex, [Cu(C(8)H(7)O(2))Cl(C(12)H(8)N(2))(H(2)O)], the Cu(II) atom is coordinated by one carboxylate O atom from a monodentate 4-methyl-benzoate ligand, two N atoms from the 1,10-phenanthroline ligand, one chloride ion and one water mol-ecule in a square-pyramidal geometry. The crystal structure exhibits inter- and intra-molecular C-H⋯Cl, C-H⋯O, O-H⋯Cl and O-H⋯O hydrogen bonds, as well as C-H⋯π inter-actions of phenanthroline and methyl H atoms towards the π-systems of neighboring 4-methyl-benzoate units and the pyridine rings of the phenanthroline system [centroid-centroid distances are 2.706 (2) and 2.
