TL;DR: A review of physically and chemically modified starches can be found in this paper, where the authors summarize the latest developments and recent knowledge regarding physically and chemical modifications of starches, including pre-gelatinization, hydrothermal and non-thermal processes.
Abstract: Starch is, after cellulose, the most abundant organic compound in nature. Modification of starch is carried out to enhance the positive attributes and to eliminate the shortcomings of the native starches. Various methods have been developed to produce a range of modified starches with a variety of characteristics and applications. Physically modified starches are simple and inexpensive because they can be produced without chemicals or even biological agents. In contrast, chemical modification is possible due to ubiquitous hydroxyl groups in starches that have been exploited for over a century, principally in the preparation of starch esters and ethers, but also in more subtle alterations, e.g., in order to tune the structure of starches for specific applications. All these techniques tend to alter the highly flexible starch polymer with changed physicochemical properties and modified structural attributes of high technological value for the food and non-food industries. Modification of starch is an ever evolving industry with numerous possibilities to generate novel starches which includes new functional and value added properties as demanded by the industry. This review aims to summarize the latest developments and recent knowledge regarding physically and chemically modified starches. This paper covers physical modification methods (pre-gelatinization, hydrothermal, and non-thermal processes), some chemical modifications and a combination of both.

TL;DR: In this paper, an extensive analysis of interpersonal distances over a large data set (N = 8,943 participants from 42 countries) was presented, which attempted to relate the preferred social, personal, and intimate distances observed in each country to a set of individual characteristics of the participants, and some attributes of their cultures.
Abstract: Human spatial behavior has been the focus of hundreds of previous research studies. However, the conclusions and generalizability of previous studies on interpersonal distance preferences were limited by some important methodological and sampling issues. The objective of the present study was to compare preferred interpersonal distances across the world and to overcome the problems observed in previous studies. We present an extensive analysis of interpersonal distances over a large data set (N = 8,943 participants from 42 countries). We attempted to relate the preferred social, personal, and intimate distances observed in each country to a set of individual characteristics of the participants, and some attributes of their cultures. Our study indicates that individual characteristics (age and gender) influence interpersonal space preferences and that some variation in results can be explained by temperature in a given region. We also present objective values of preferred interpersonal distances in different regions, which might be used as a reference data point in future studies.

TL;DR: In this paper, the authors presented a review of green and biobased coagulants for water and wastewater treatment operations, and the factors militating against the transition of the applications of these non-conventional coagULs from bench-scale to real-life applications were discussed.
Abstract: Metal and polymer based materials are the conventional coagulants used in water and wastewater treatment operations. Despite the wide applicability of these genera of coagulants, the challenges associated with the usage have engendered research efforts towards the development of green biobased coagulants, whose applications are capable of obviating the challenges synonymous with the usage of these conventional coagulants. Taking into cognizance the goals that informed the development of green technology, perspectives on the promising non-conventional coagulants that are green and biobased are presented in this treatise. The perspectives on these green biobased coagulants were anchored on the background information of the material, the economic importance, mode of application of the extract as coagulant, underlying coagulating mechanism and the shortcomings of the usage in water and wastewater treatment operations. On the basis of the information provided by different researchers, on the appraisals of these green biobased coagulants for water and wastewater treatment operations, the factors militating against the transition of the applications of these non-conventional coagulants from bench-scale to real life applications were discussed.
