ABSTRACTMussel‐inspired dopamine chemistry is popular among engineers for surface modification on various substrates due to its high efficiency, handy operation process, and strong reactivity. However, the high cost of dopamine does not allow for mass production. In the present study, low‐cost dopamine analogues (alkali lignin and tannic acid) were used to fabricate high‐reactivity silkworm silk fiber (SF) via a simple dip‐coating approach, and were then applied to a soy‐based adhesive to enhance its performance. The SF tightly combines with soy protein mainly via a Schiff base reaction between polydopamine or dopamine analogue and the amine or thiol groups of soy protein; this forms a multiple crosslinked system and “reinforced concrete”‐like structure, as confirmed by Fourier transform infrared spectroscopy, X‐ray diffraction, thermogravimetry, and scanning electron microscopy analyses. As expected, the toughness of the soy‐based adhesive obviously improved and the highest wet shear strength of the adhesive samples attained 1.50 MPa, which is far greater than relevant interior use requirements. Though dopamine‐coated SF could significantly enhance the wet shear strength of the soy‐based adhesive by 387.1% compared to the pristine SM adhesive, lignin‐coated and tannic acid‐coated SFs are more suitable for practical application due to the lower cost of raw materials. The results of this study may represent an effective and low‐cost approach to mussel‐inspired surface modification chemistry for the mass production of high‐performance soy‐based adhesives. © 2019 Wiley Periodicals, Inc.

Published: December 2019

AbstractThe antisocial and violent behaviors of cult‐like religious groups (CRGs) and the maladaptive social consequences of their activities suggest clinical or character pathology and invite diagnostic and dynamic formulations of their members' personalities. The current study utilized secondary reports in the commercial media about CRG members, combined with the lived experience method of two of the authors. The resulting core characteristics of CRG members were then classified following the alternative DSM‐5 alternative model for personality disorders. The overall clinical picture is then discussed in terms of the shared psychodynamic sources that undergird the behaviors of the antisocial‐obsessive‐compulsive personality disorders. By tracing the personality characteristics into their unconscious sadomasochistic conflicts, these insights shed light on the paradoxical frequent co‐occurrence of antisocial and obsessive‐compulsive characteristics among extremists, in contrast to the patient population at large.
Methacrylate: An alternative fixing agent for identifying the botanical origin of propolis
Authors: Teixeira Érica W. , Message Dejair , Meira Renata M. S. A. 
Published: December 2019

PremiseA new technique was developed to identify the botanical origin of propolis, a resin‐like material made by bees by mixing saliva and beeswax with plant buds and exudates, using methacrylate for permanent slide preparation.Methods and ResultsPropolis samples were fixed in methacrylate to produce permanent slides. The anatomical structures of the plant fragments in the methacrylated propolis were compared with propolis slides prepared using conventional techniques that consist of propolis sediment obtained during a series of solvent reactions, filtration, and centrifugations, which cost a similar amount to produce. The techniques resulted in qualitative differences between the slides obtained. The methacrylated propolis sections allowed the detailed observation and identification of plant anatomical structures that were obscured in samples prepared using the conventional procedure. This clarity enabled the detailed evaluation of valuable taxon‐diagnostic characters in a permanent slide, which can also be used for histochemical tests.ConclusionsThe methacrylated embedding of propolis is an affordable technique that could be implemented as a routine laboratory procedure. This new technique enables the efficient determination of the botanical origin of propolis.

Published: December 2019

AbstractIntroductionOrientation of the Round Window Membrane (RWM) is an important metric to establish if utilized as a potential access for targeted delivery of magnetically guided nanomedicines to the inner ear. Orientation with respect to an internal reference frame (such as the planes defined by the semicircular‐canals [SCC]) may provide an internally consistent basis if the basis is orthogonal and consistent (from patient to patient).Materials and MethodsUtilizing a micro computed tomography (CT), 20 temporal bones are scanned for anatomical information. The scanned data sets are loaded into an imaging program to provide volumetric reconstruction and segmentation. Volumetric models of the anatomical relationships between the inner ear SCC and the RWM are utilized to get normative projection angle information and are statistically analyzed.ResultsMicro‐CT shows low to moderate reliability for reproducibility, intraobserver, and interobserver measurements; in addition, it provides mean values (±SD) for the various measured angles. The combined mean angular values for surface orientation of the RWM, with respect to the SCC basis (quasi‐orthogonal spherical coordinate system), was 57.0° ± 20.9°as measured from the line defining the posterior SCC plane in the direction of the line defining the superior SCC plane. An angle of 65.2° ± 19.1° was measured for an angle away from the line defining the horizontal SCC plane.

Published: December 2019

AbstractTo separate small molecules from the solvent with high permeability and selectivity, the membrane process is thought to be highly effective with much lower energy consumption when compared to the traditional thermal‐based separation process. To achieve high solvent permeance, a sub‐10 nm thick polyamide nanofiltration membrane was synthesized through interfacial polymerization of ethidium bromide (EtBr) and trimesoyl chloride (TMC). Thanks to the extremely low solubility of the EtBr monomer in the organic phase, the polymerization process was strictly limited at the interface of the water and hexane, leading to an ultrathin polyamide membrane with a thickness down to sub‐10 nm. When used in nanofiltration, these ultrathin membranes display ultrafast water permeation of 40 liter per square meter per hour per bar (L m−2 h−1 bar−1), and a high Congo red rejection rate of 93 %. This work demonstrates a new route to synthesize ultrathin polyamide membranes by the traditional interfacial polymerization.
Metabolic engineering strategies for consolidated production of lactic acid from lignocellulosic biomass
Authors: Mazzoli Roberto 
Published: December 2019

AbstractLactic acid (LA) is one of the most desired molecules by the chemical industry. Current expansion of LA market is mainly driven by its application as building block for the synthesis of polylactide (PLA), that is, a family of biodegradable and biocompatible plastic polymers. PLA can potentially replace oil‐derived polymers as general purpose plastic, but current LA prices fails to make PLA cost‐competitive with traditional plastics. Nowadays, LA is mainly produced by fermentation of expensive starchy biomass. Hopefully, cheaper lignocellulosic feedstock could be used in future second‐generation biorefinery processes. However, most efficient natural LA producers cannot ferment lignocellulose without prior biomass saccharification. Metabolic engineering may develop improved microorganisms that feature both efficient biomass hydrolysis and LA production, thus supporting consolidated bioprocessing (CBP), that is, one‐pot fermentation, of lignocellulose to LA. CBP could dramatically reduce LA production cost, thus contributing to the expansion of more environmental sustainable plastics and commodity chemicals. This review presents an overview of “recombinant cellulolytic strategies”, mainly consisting in introducing cellulase systems in native producers of LA, and “native cellulolytic strategies” aimed at improving LA production in natural cellulolytic microorganisms. Issues and perspectives of these approaches will be discussed.

Published: December 2019

AbstractHigh‐capacity electrode materials have attracted tremendous attention in energy storage systems. However, the large volume expansion always causes breakdown of electrode materials and capacity fading. In this work, we report the preparation of heterogeneous Fe3O4/Fe7S8/C nanoplates with a high lithium diffusion coefficient and excellent lithium storage performance. The heterogeneous nanoplates can be derived from Fe‐MOF octahedra during the sulfidation process. As an anode for lithium‐ion batteries, the Fe3O4/Fe7S8/C composite exhibits higher specific capacity and better rate capability than Fe3O4/C and Fe7S8/C counterparts. The Fe3O4/Fe7S8/C nanoplates deliver a reversible capacity of 859 mA h g−1 after 100 cycles at 0.1 A g−1. Even at 2 A g−1, a capacity of 549 mA h g−1 can still be remained. The good performances are attributed to the small nanocrystallites, high surface area, and the heterogeneous phase boundaries. The strategy can be potentially applied to other metal oxide/metal sulfide composite phases or even bimetallic sulfides and bimetal oxides for high performance lithium‐ion batteries.

Cell‐surface exposure of a hybrid 3‐cohesin scaffoldin allowing the functionalization of Escherichia coli envelope
Authors: Vita Nicolas , Borne Romain , Fierobe Henri‐Pierre 
Published: December 2019

AbstractCellulosomes are large plant cell wall degrading complexes secreted by some anaerobic bacteria. They are typically composed of a major scaffolding protein containing multiple receptors called cohesins, which tightly anchor a small complementary module termed dockerin harbored by the cellulosomal enzymes. In the present study, we have successfully cell surface exposed in Escherichia coli a hybrid scaffoldin, Scaf6, fused to the curli protein CsgA, the latter is known to polymerize at the surface of E. coli to form extracellular fibers under stressful environmental conditions. The C‐terminal part of the chimera encompasses the hybrid scaffoldin composed of three cohesins from different bacterial origins and a carbohydrate‐binding module targeting insoluble cellulose. Using three cellulases hosting the complementary dockerin modules and labeled with different fluorophores, we have shown that the hybrid scaffoldin merged to CsgA is massively exposed at the cell surface of E. coli and that each cohesin module is fully operational. Altogether these data open a new route for a series of biotechnological applications exploiting the cell‐surface exposure of CsgA‐Scaf6 in various industrial sectors such as vaccines, biocatalysts or bioremediation, simply by grafting the small dockerin module to the desired proteins before incubation with the engineered E. coli.

Abstract

Background
Surgical outcomes may be associated with hospital volume and the influence of volume on minimally invasive liver surgery (MILS) is not known.

Methods
Patients entered into the prospective registry of the Italian Group of MILS from 2014 to 2018 were considered. Only centres with an accrual period of at least 12 months and stable MILS activity during the enrolment period were included. Case volume was defined by the mean number of minimally invasive liver resections performed per month (MILS/month).

Results
A total of 2225 MILS operations were undertaken by 46 centres; nine centres performed more than two MILS/month (1376 patients) and 37 centres carried out two or fewer MILS/month (849 patients). The proportion of resections of anterolateral segments decreased with case volume, whereas that of major hepatectomies increased. Left lateral sectionectomies and resections of anterolateral segments had similar outcome in the two groups. Resections of posterosuperior segments and major hepatectomies had higher overall and severe morbidity rates in centres performing two or fewer MILS/month than in those undertaking a larger number (posterosuperior segments resections: overall morbidity 30·4 versus 18·7 per cent respectively, and severe morbidity 9·9 versus 4·0 per cent; left hepatectomy: 46 versus 22 per cent, and 19 versus 5 per cent; right hepatectomy: 42 versus 34 per cent, and 25 versus 15 per cent).

Conclusion
A volume–outcome association existed for minimally invasive hepatectomy. Complex and major resections may be best managed in high-volume centres.

AbstractBlack pepper (Piper nigrum; BP), known as the ‘king of spices’, imported from various countries is widely available in Saudi Arabian markets, as its demand as a food as well as a medicine for minor ailments is increasing in the country. However, there is a lack of appropriate information regarding these samples in terms of quality variation and standardization. We thus aimed to evaluate the quality and standardize the BP sample with respect to its physicochemical characters, active principle variation [i.e. piperine (PPN)], toxicity, and biological activity. The main focus is to validate whether any difference exists in the quality and quantity of active principle in these samples. For this purpose, physicochemical (chemical tests and ash values) and instrumental analyses [accelerated solvent extraction (ASE), ultra‐high‐pressure liquid chromatography (UHPLC)‐diode array detector, infrared (IR), nuclear magnetic resonance (NMR), and inductively coupled plasma‐MS (ICP‐MS)] and biological evaluation {in vitro antioxidant activity [2,2‐diphenyl‐1‐picrylhydrazyl and 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid)] and cytotoxicity assay} were performed. An extract yield (g) with %recovery of 2.26 ± 4.24 (11.3) was obtained for the Vietnamese sample, using a fast and rapid method of extraction (ASE). These values were 1.22 ± 2.64 (6.1) and 0.75 ± 1.69 (3.75) for the Pakistani and Indian samples. Physicochemical tests revealed the presence of flavonoids and phenolic compounds in all samples; however, in the Vietnamese sample a low amount of total, acid‐insoluble, and high water‐soluble ash value was noted. IR and NMR was applied to further standardize the samples. Results of ICP‐MS analysis showed a high amount of macronutrients and micronutrients in the samples tested while UHPLC analysis revealed a high amount of PPN (ng/mL) in the Pakistani sample (1,362,614.09); these values were 1,051,848.04 and 768,512.81 for the Vietnamese and Indian samples, respectively. In vitro antioxidant and cytotoxicity activities revealed higher potential for the Vietnamese sample. The samples were properly standardized and effectively differentiated in terms of quality and biological activities using a fast and reliable method, however it certainly does not mean that a particular geographical region is more better or productive in terms of herbal products.
Multiple certification uptake by coffee businesses: Evidence of functions and benefits from Central America
Authors: Donovan Jason , Blare Trent , Peña Meliza 
Published: December 2019

AbstractThis article examines why and how nine coffee businesses in Central America engaged with multiple certification systems and the related functions and benefits. The businesses implemented, on average, four systems. Certification, in general, strengthened their negotiation position vis‐à‐vis exporters and international buyers, whereas multiple certification reduced the risks inherent in their reliance on any one certification, allowing businesses to sell as much coffee as possible at a relatively higher price. However, commitments to the certification's underlying goals were tenuous: Businesses engaged a subgroup of their supplier base in any one label, and coffee buyers purchased relatively small volumes of certified coffees, at times, conditioned on access to larger volumes of noncertified coffees. Although certification facilitated capacity upgrading, in many cases, the changes were minor and might have taken place without certification. Results suggest that multiple certification helps sustain small‐scale coffee exporters but dampen expectations that certification will drive long‐term systemic change in the sector. We conclude with recommendations for certification agencies and others that seek to support coffee businesses to expand their engagement in certified coffee markets.
Exploring networks of proximity for partner selection, firms' collaboration and knowledge exchange. The case of clean‐tech industry

Published: December 2019

AbstractNowadays scholars widely recognize that know‐how, capabilities and knowledge needed to generate innovations often reside outside the firm, start‐ups are a valuable source, and collaborative networks are a fundamental strategy for innovation. This is true especially for the clean‐tech sector, which is characterized by the continuous search for innovative solutions and technological advancements. The purpose of the paper is to provide a methodological support for the screening of potential partners based on network analysis and, then, help firms to select them for collaboration and knowledge exchange. The methodology can be easily adopted by managers and executives to identify firms to monitor with greater attention for future investments. The analysis is on a dataset of 4,782 clean‐tech companies operating worldwide. Results highlight that energy companies looking for external sources could investigate their network of business proximity if they intend to specialize in a defined field and/or collaborate with similar partners, while they could explore their network of strategic proximity if they intend to diversify their businesses, that is cooperating and exchanging knowledge with firms with distant but complementary capabilities and resources.

Published: December 2019

AbstractConstruction of model metal carbide surfaces is essential for surface catalysis studies over carbide‐based catalysts. Here, well‐controlled growth of tungsten carbide (WCx) layers on W(110) including carbon‐rich R(15×3)‐C/W(110) and carbon‐poor R(15×12)‐C/W(110) structures has been clearly demonstrated using chemical vapor deposition (CVD) on a clean W(110) surface or carbon segregation from the bulk. Low‐energy electron microscopy (LEEM) and micro‐region LEED (μ‐LEED) characterizations confirm that the R(15×12) structure forms first and then transforms to the R(15×3) structure by incorporating more carbon atoms in the CVD or surface segregation processes. Oxidation of the WCx/W(110) surfaces in O2 atmosphere removes surface carbon atoms, driving the structural transformation from R(15×3) to R(15×12) first and then to a two‐dimensional oxide surface. Our work provides a clear guide for well‐controlled growth of model WCx catalysts and the structural transformation between them.

Published: December 2019

Abstract1‐Butyl‐3‐methylimidazolium hydrogen sulfate ([Bmim][HSO4]) is utilized to catalyze transesterification of camelina oil with methanol. The major compositions of camelina biodiesel are saturated fatty acid esters (C16:0, C18:0), monounsaturated, and polyunsaturated fatty acid esters (C18:2, C18:3). The effects of reaction temperature, reaction time, Mmethanol:MCamelina oil, and M[Bmim][HSO4]:MCamelina oil on biodiesel production are investigated in detail, and a general mathematical model is developed to well predict the biodiesel yield. Also, [Bmim][HSO4] is thermally stable to recycle for four times with a high biodiesel yield. The fuel properties of camelina biodiesel are all comparable to the American Society for Testing Materials (ASTM) standards.
