  2. 1. CO2 electrochemical reduction: Techno-economic evaluation and experimental research for producing methanol

    Author : Fangfang Li; Xiaoyan Ji; Joakim Lundgren; Klas Engvall; Hailong Li; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : Recently, CO2 electrochemical reduction (CO2R) has gained popularity, to cope with the strict environmental rules on greenhouse gas emissions, and to convert CO2 to value-added chemicals/fuels. Ionic liquids (ILs) have been considered as potential media for CO2R owing to their multi-functions in enhancing CO2R solubility and improving CO2R reaction rate and product selectivity. READ MORE

  4. 2. Conformationally Constrained Oligonucleotides for RNA Targeting

    Author : Qing Li; Jyoti Chattopadhyaya; Li-He Zhang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conformationally constrained nucleoside; antisense oligonucleotide; RNA affinity; nuclease stability; RNase H; RNA degradation; Chemistry with specialization in Bioorganic Chemistry; Kemi med inriktning mot bioorganisk kemi;

    Abstract : A short oligonucleotide sequence as in a single-stranded antisense oligo nucleotides (AON) or in double-stranded small interfering RNAs (siRNA) can modulate the gene expression by targeting against the cellular mRNA, which can be potentially exploited for therapeutic purposes in the treatment of different diseases. In order to improve the efficacy of oligonucleotide-based drugs, the problem of target affinity, nuclease stability and delivery needs to be addressed. READ MORE
