Prostatic diseases such as prostate can.er an. ben.gn.prostatic hyperplasia are highly prevalen. amon. men. The n.mber of studies focused on.the abun.an.e an. roles of in.rin.ically disordered protein. in.prostate can.er is rather limited. The goal of this study is to an.lyze the prevalen.e an. degree of disorder in.protein. that were previously associated with the prostate can.er pathogen.sis an. to compare these protein. to the en.ire human.proteome. The an.lysis of these datasets provides mean. for drawin. con.lusion. on.the roles of disordered protein. in.this common.male disease. We also hope that the results of our an.lysis can.poten.ially lead to future experimen.al studies of these protein. to fin. n.vel pathways associated with this disease.

Arrestin. are soluble relatively small 44-46 kDa protein. that specifically bin. hun.reds of active phosphorylated GPCRs an. dozen. of n.n.receptor partn.rs. There are bin.in. partn.rs that demon.trate preferen.e for each of the kn.wn.arrestin.con.ormation.: free, receptor-boun., an. microtubule-boun.. Recen. eviden.e suggests that con.ormation.l flexibility in.every fun.tion.l state is the defin.n. characteristic of arrestin.. Flexibility, or plasticity, of protein. is often.described as structural disorder, in.con.rast to the fixed con.ormation.l order observed in.high-resolution.crystal structures. However, protein.protein.in.eraction. often.in.olve highly flexible elemen.s that can.assume man. distin.t con.ormation. upon.bin.in. to differen. partn.rs. Existin. eviden.e suggests that arrestin. are n. exception.to this rule: their flexibility is n.cessary for fun.tion.l versatility. The data on.arrestin. an. man. other multi-fun.tion.l protein. in.icate that in.man. cases, "order" might be artificially imposed by highly n.n.physiological crystallization.con.ition. an./or crystal packin. forces. In.con.rast, con.ormation.l flexibility (an. its extreme case, in.rin.ic disorder) is a more n.tural state of protein., represen.in. true biological order that un.erlies their physiologically relevan. fun.tion..

The aim of the presen. work is to con.irm the fun.amen.al possibility of creatin. n.w gen.ration.of the n.n.structured composite coatin.s-orien.an.s are studied un.er con.ition. of boun.ary lubrication.in.in.ctive oil, as green.tribology aspect an. to experimen.ally prove the efficacy of the n.n.structured composite coatin.s-orien.an.s for en.in.erin. application.. Tribological properties of n.n.structured composite coatin.s-orien.an.s are studied un.er con.ition. of boun.ary lubrication.in.in.ctive oil, as green.tribology aspect. The friction.tests were carried out by usin. two test con.iguration.: “ball-on.disc” an. “rin.-to-rin.”. As lubrican.s some model an. commercial oils were used. It is foun. that the friction.coefficien. an. its temperature depen.en.e differ sign.fican.ly for n.n.structured composite coatin.s un.er study. The obtain.d results were attributed to differen. orien.atin. effect of these coatin.s on.structural orderin. in.boun.ary layers, which structure is con.idered as a mesophase of liquid crystals. The fin.in.s suggest that the n.n.structured composite coatin.s-orien.an.s with orien.atin. effect on.boun.ary layers are advan.ageous for improvin. an.ifriction.characteristics an. for govern.n. processes of boun.ary lubrication. The n.n.structured composite coatin.s-orien.an.s can.improve lubricatin. properties of oils (with an. without additives) an. may be advan.ageous for en.in.erin. practice as they improve an.ifriction.characteristics of rubbin. pairs an. allow con.rollin. the processes of boun.ary lubrication. Thus, received n.n.structured composite coatin.s-orien.an.s can.be today the best materials of green.tribology in.en.in.erin..

近年来煤炭、石油、天然气等传统能源逐渐枯竭,大量化石能源的使用造成环境污染。为了降低二氧化碳的排放量,国家积极推动风、光、水电、氢能等可再生能源的发展,而这些能源技术的推广应用的关键是新材料的研发。目前新材料的研发主要依赖于研究者根据材料结构以及其用于某一特定体系的预期催化活性为目标进行实验优化,导致新材料研发过程缓慢。随着计算材料学的进一步发展,研究人员整合了大量关于材料结构及性能表征的材料数据库,通过比较逐步优化筛选新材料。综述了当前材料开发的设计思路以及合成方法,以人工智能(AI)为着眼点阐述了近年来基于AI方法设计、制备可再生能源材料过程中的模型与算法,并总结了AI用于材料设计方面的研究意义和发展过程,最后对AI方法用以可再生能源材料设计、制备的发展进行了展望,介绍了本课题组提出的材料优化模型,并且列举了该模型成功应用于电解水析氢以及硼氢化钠制氢的材料优化的案例。未来,AI技术在新材料的理论计算、合成设计、性能预测、材料微观结构表征分析等方面具有非常广阔应用前景。
