2Plant Surfaces:Structures and Functions for Biomimetic Innovations显示文摘An overview of plant surface structures and their evolution is presented. It combines surface chemistry and architecture with their functions and refers to possible biomimetic applications. Within some 3.5 billion years biological species evolved highly complex multifunctional surfaces for interacting with their environments: some 10 million living prototypes(i.e., estimated number of existing plants and animals) for engineers. The complexity of the hierarchical structures and their functionality in biological organisms surpasses all abiotic natural surfaces: even superhydrophobicity is restricted in nature to living organisms and was probably a key evolutionary step with the invasion of terrestrial habitats some 350–450 million years ago in plants and insects. Special attention should be paid to the fact that global environmental change implies a dramatic loss of species and with it the biological role models. Plants, the dominating group of organisms on our planet, are sessile organisms with large multifunctional surfaces and thus exhibit particular intriguing features.Superhydrophilicity and superhydrophobicity are focal points in this work. We estimate that superhydrophobic plant leaves(e.g., grasses) comprise in total an area of around 250 million km^2, which is about 50% of the total surface of our planet. A survey of structures and functions based on own examinations of almost 20,000 species is provided, for further references we refer to Barthlott et al.(Philos. Trans. R. Soc. A 374: 20160191, 1). A basic difference exists between aquatic nonvascular and land-living vascular plants; the latter exhibit a particular intriguing surface chemistry and architecture. The diversity of features is described in detail according to their hierarchical structural order. The first underlying and essential feature is the polymer cuticle superimposed by epicuticular wax and the curvature of single cells up to complex multicellular structures. A descriptive terminology for this diversity is provided. Simplified, the functions of plant surface characteristics may be grouped into six categories:(1) mechanical properties,(2) influence on reflection and absorption of spectral radiation,(3) reduction of water loss or increase of water uptake, moisture harvesting,(4) adhesion and nonadhesion(lotus effect, insect trapping),(5) drag and turbulence increase, or(6) air retention under water for drag reduction or gas exchange(Salvinia effect). This list is far from complete. A short overview of the history of bionics and the impressive spectrum of existing and anticipated biomimetic applications are provided. The major challenge for engineers and materials scientists, the durability of the fragile nanocoatings, is also discussed.Wilhelm Barthlott Matthias Mail Bharat Bhushan Kerstin Koch 2017Nano-Micro Letters2017,9,2:16
3湍流流动中鲨鱼皮表面流体减阻研究进展显示文摘快速游动的鲨鱼,其皮肤表面沿流动方向有序地排列着沟槽状结构,人们认为这种结构能在湍流流动中减小表面摩擦阻力.人们仿真这种生物结构来进行实验研究和应用,通过复制和改善鲨鱼皮肤表面沟槽状结构,使得摩擦阻力最大减小了近10%.在实验和模拟仿真中,人们不断讨论和研究湍流流动阻力的形成机制和沟槽减阻的理论特性.本文综述了沟槽减阻理论特性的一些研究方法,并且归纳定义了沟槽减阻最优几何形状及其尺寸;详细考虑流体流动的特点,给出了一种用来选择最优沟槽形状及其尺寸的方法;综述了目前的沟槽加工制造技术.由于鲨鱼皮肤表面存在少量黏液,从仿生学的角度,文章最后综述并展望了通过局部应用疏水性材料来改变沟槽附近流场属性,从而达到更大程度上减小阻力的目标.Brian Dean Bharat Bhushan 杨绍琼(译) 李山(译) 田海平(译) 李一凡(译) 姜楠(校) 2012力学进展2012,42,6:13

5Functional properties, phenolic constituents and antioxidant potential of industrial apple pomace for utilization as active food ingredient显示文摘Apple pomace is a waste biomass generated after apple fruit processing.In present investigation,efforts were made to comprehend influence of differently dried pomace on cell wall properties and phenolic profile.Different drying techniques were employed to remove moisture content from fresh apple pomace.Total dietary fiber yield(74%)and array of functional properties such as density,water and oil holding capacity,swelling capacity and glucose dialysis retardation index(36.91%)was found better in freeze dried fraction.The higher total phenolics(5.78±0.08 mg GAE/g dry weight)content was also recorded in freeze dried fraction followed by oven and sun drying.The 50%aqueous acetone was found as more efficient solvent for extraction of phenolic constituents.RP-HPLC analysis has revealed presence of quercetin,phloridzin and phloretin as major phenolics.Thus,it is evident from the results that pomace generated at industrial scale can be utilized as a source of dietary food ingredient.Shalika Ranaa Sakshi Gupta Ajay Rana Shashi Bhushan 2015Food Science and Human Wellness2015,4,4:8
6Plant-Based Rasayana Drugs from Ayurveda显示文摘Rasayana tantra is one of the eight specialties of Ayurveda.It is a specialized practice in the form of rejuvenative recipes,dietary regimen,special health promoting behaviour and drugs.Properly administered Rasayana can bestow the human being with several benefits like longevity,memory,intelligence,freedom from diseases,youthful age,excellence of luster,complexion and voice,optimum strength of physique and sense organs,respectability and brilliance.Various types of plant based Rasayana recipes are mentioned in Ayurveda. Review of the current literature available on Rasayanas indicates that anti-oxidant and immunomodulation are the most studied activities of the Rasayana drugs.Querying in Pubmed database on Rasayanas reveals that single plants as well as poly herbal formulations have been researched on.This article reviews the basics of Rasayana therapy and the published research on different Rasayana drugs for specific health conditions.It also provides the possible directions for future research.Subramani Paranthaman Balasubramani Padma Venkatasubramanian Subrahmanya Kumar Kukkupuni Bhushan Patwardhan 2011Chinese Journal of Integrative Medicine2011,17,3:6

11Coexistence of pneumothorax and chilaiditi sign:A case report显示文摘We present a case of 50 year old male patient with coexistence of Pneumothorax and Chilaiditi sign.Chilaiditi sign is an incidental radiographic finding of a usually asymptomatic condition in which a part of intestine is located between the liver and diaphragm;however,the term'Chilaiditi syndrome'is used for symptomatic hepatodiaphragmatic interposition.The patient had no symptoms of abdominal pain,constipation,diarrhea,or emesis.Incidentally,Chilaiditi sign was diagnosed on chest radiography.Pneumothorax is defined as air in the pleural space.Pneumothoraces are classified as spontaneous or traumatic.Spontaneous pneumothorax is labelled as primary when no underlying lung disease is present,or secondary,when it is associated with pre-existing lung disease.Our case is the rare in the literature indicating the coexistence of Chilaiditi sign and pneumothorax.Tangri Nitin Singhal Sameer Sharma Priyanka Mehta Dinesh Bansal Sachin Bhushan Neeraj Singla Sulbha Singh Puneet 2014Asian Pacific Journal of Tropical Biomedicine2014,4,1:2

14木豆CGMS杂交种生产中的传粉昆虫显示文摘木豆是世界上唯一的木本食用豆类作物,具有较强的抗旱性。木豆杂交制种需昆虫传粉,制种地传粉昆虫的种类及数量是制种产量的决定性因素。本文调查了云南省元谋县CGMS木豆[Cajanus cajan(L.) Millspaugh]杂交种ICPH2671制种田访花昆虫种类、数量、访花频次及杂交种制种产量。结果表明,在云南元谋,木豆访花昆虫共有5目15科25种,其中主要5种传粉媒介为绒切叶蜂(Megachile velutina)、切叶蜂属1种(Megachile sp5)、圆柄木蜂(Xylocopa tenuiscapa)、蜜蜂亚科1种(Apinae sp1)和切叶蜂属1种(Megachile sp2)。木豆盛花期,制种亲本不育系每个分枝昆虫访花频次为每10min 2.8次,而恢复系植株上的访花频次为每10min 5.2次,表明昆虫对恢复系花朵有明显偏好;在前述昆虫访花频次下,不育系单株干籽粒产量达383.7g,恢复系单株产量为357.0g,二者无显著差异,说明这样的昆虫访问频次已能满足杂交制种中将花粉由恢复系传至不育系的需要。李正红 梁宁 马宏 Kul Bhushan SAXENA 刘秀贤 宗绪晓 2011作物学报2011,37,12:2
