Catalytic transformation of 5-hydroxymethylfurfural (HMF) to produce 2,5-dimethylfuran (2,5-DMF) was studied over bimetallic (PtIr) and monometallic (Pt) catalysts supported on CMK-3 SBA-15 mesoporous materials. The optimum temperature hydrogen pressure for the maximum production 2,5-DMF were 120 °C 15 atm, respectively. Increases in decreased selectivity 2,5-DMF. broadly characterized by diffe...

Highly ordered mesoporous silica can be regenerated from a mesoporous carbon CMK-3 that is a negative replica of mesoporous silica SBA-15, indicating reversible replication between carbon and inorganic materials.

Two twin series of carbon replicas were synthesized by the acid-catalyzed precipitation polycondensation various amounts furfuryl alcohol in SBA-15 suspensions using water and toluene as reaction media. The textural structural parameters, well morphology polymer/silica carbonizates corresponding replicas, investigated comprehensively. It was found that polarity medium plays an essential role sc...

Aqueous zinc-ion batteries (AZIBs) have become a current research hotspot owing to their high security and cost-effectiveness. However, the dissolution of electrode materials, low intrinsic conductivity, slow reaction kinetics seriously hinder practical application. Herein, sulfur-containing organic small molecule (seriniquinone, SQ), which plays significant role in melanoma treatment, was synt...

The human immunodeficiency virus (HIV) is capable of infecting certain cells of hematopoietic lineage, particularly monocyte-macrophages and T lymphocytes. Recently, the possibility that cells of megakaryocytic lineage are susceptible to HIV infection has been raised. We have characterized infection of the permanent megakaryocytic cell line CMK by HIV in vitro. CMK cells were easily infected by...

Information about nutrient availability is assessed via largely unknown mechanisms to drive developmental decisions, including the choice of Caenorhabditis elegans larvae to enter into the reproductive cycle or the dauer stage. In this study, we show that CMK-1 CaMKI regulates the dauer decision as a function of feeding state. CMK-1 acts cell-autonomously in the ASI, and non cell-autonomously i...

Mutants of Salmonella typhimurium defective in cytidine 5'-monophosphate (CMP) kinase (cmk) have been isolated. The mutants also lack the ability to phosphorylate 2'-deoxyCMP, indicating that one enzyme is responsible for the phosphorylation of both CMP and deoxyCMP to the corresponding diphosphates. In glucose minimal medium the mutants grow at the same rate as the parental strain; however, th...
