Authors: Wahyudi Tatang , Kasipah Cica , Wahyudi Agus 
Published: November 2018

Telah dilakukan penelitian modifikasi nano bentonit alam yang berasal dari daerah Tasikmalaya Jawa Barat menjadi organobentonit dengan cara mereaksikannya dengan heksadesiltrimetilamonium bromida dan tetrabutilfosfonium bromida untuk dapat digunakan sebagai zat tahan api pada proses penyempurnaan tekstil. Proses pembuatan organobentonit dilakukan dengan cara pengadukan menggunakan magnetic stirrer larutan suspensi nanobentonit sebanyak 2% dengan heksadesiltrimetilamonium bromida (HDTA)/tetrabutilfosfonium bromida (TBP) variasi kadar 0,4-2 %. Karakterisasi organobentonit hasil sintesis dilakukan dengan menggunakan FTIR dan SEM. Percobaan aplikasi organobentonit hasil sintesis pada kain kapas dilakukan dengan bantuan binder poliuretan serta surfaktan non ionik, sedangkan teknik yang digunakan adalah pad-dry-cure, dengan kondisi pad (90% WPU)-dry (110oC, selama 3 menit)-cure (140oC, selama 3 menit). Hasil percobaan menunjukkan bahwa HDTA-bentonit dan TBP-bentonit hasil sintesis dapat meningkatkan sifat tahan api sampel kain kapas meskipun belum secara signifikan, namun demikian telah memperlihatkan pembentukan arang kain sebagai sisa hasil pembakarannya. Pengarangan sampel kain hasil penyempurnaan dengan TBP-bentonit lebih tinggi dibanding dengan HDTA-bentonit.

Environmental change always occurs continuously in the process of development of a country. This development is directly orindirectly will affect the order of social life, economy, culture, technology and lifestyle community. The changes in the economic, social community of course affect the marketing system in the country. A very rapid technological developments lately has affected all areas of human activity. The development of this technology has tightened competition in the marketing system in the marketing world, where the procedures must innovate continuously in order to win and retain the loyalty of its customers. Currently in Indonesia there are nine mobile operators include (indosat, Telkomsel, XL, Mobile-8, Three, Flexi, Esia, Smart and Axis). When walking in the center of mobile sales, mobile phones can be seen many types of operators who have their own packaging designs appeal to consumers. Display a bundle is now realized by the manufacturer is no longer only have the function of protecting and wrapping products but products that increasingly tight competition in the market requires manufactures to think hard in improving the function of packaging to be able to provide attraction to consumers through the artistic aspect, color, graphic, from or the design. The results of simple correlation analysis found a correlation between changes in the new packaging with the purchase of consumer preferences is 0.293. this suggests that there is a strong relationship between the new packaging Esia with consumer purchasing preferences. While the relationship is positive because it is positive. This means that the new packaging Esia has a strong positive relationship towards the purchase of consumer preferences. This relationship is positive where this Esia packaging changes increase consumer purchasing preferences of Esia. Analytical results obtained coefficient of determination coefficient of determination between the change in the new packaging with the purchase of consumer preferences is the 0086 (8.6%). This suggests that the level of consumer preferences towards new product packaging can be influenced by the old product by 8.6%, the remaining 91.4%influenced by other factors. The coclusion is that between the old and new packaging packaging there is a correlation effect on customer preferences in choosing which 8.6% can be seen that the old product is still influencing new product, and the remaining 91.4% is another factor affecting.
Morphogenèse des hélictites monocristallines
Authors: Andrieux C. 
Published: November 2018

L'auteur montre que des édifices monocristallins et excentriques de calcite, appelés encore « hélictites », naissent et se développent dans les grottes dont le régime hydraulique et le climat ; sont stables. Ces grottes sont, en général, situées à faible profondeur dans des terrains calcaires homogènes : les hélictites sont abondantes dans les galeries situées prés du sol pédologique.
Il essaie de montrer que la croissance excentrique peut être due à la présence d'impuretés adsorbables de la calcite et inhibitrices de la croissance ; ces impuretés proviendraient du sol pédologique.
L'eau traversant le canalicule est responsable de l'allongement des hélictites, alors que l'eau provenant de la paroi, et maintenue sur tout l'édifice par des forces de tensions superficielles, assure l'épaississement.
Contribution à l'étude pétrographique et magnétique des basaltes de la région de Monistrol˗d'Allier (Haute-Loire)
Authors: Babkine Jean 
Published: November 2018

Après une étude optique des différents minéraux constituant les basaltes de la région de Monistrol˗d'Allier, les propriétés magnétiques de la roche ont permis de déterminer la composition des minéraux opaques en lame mince. Dans les coulées de grande épaisseur ce minéral est en général une titanomagnétite (25 % de Fe₃O₄ environ) dans les parties compactes et centrales. Celle-ci évolue en une série de titanomagnétites « généralisées » vers la base et le sommet avec apparition, dans les parties les plus oxydées, de phases rhomboédriques (hématite et ferri˗ilménite). Cette oxydation reproduite expérimentalement, se manifeste par le faisceau de courbes thermomagnétiques et par les variations de l'aimantation à saturation. Dans les coulées de faible épaisseur le minéral opaque est une titanomagnétite renfermant des exsolutions d'ilménite.

La balance de mesures magnétiques décrite est basée sur un principe dû à Weiss et Foëx. Elle comporte un certain nombre de perfectionnements, à savoir :
— l'adjonction d'un flotteur plongeant dans un liquide de densité élevée, servant à la diminution de la masse apparente de l'équipage mobile ainsi qu'à son amortissement ;
— le dispositif de repérage du zéro de l'appareil, constitué par deux cellules photorésistantes montées dans un pont de Wheatstone et donnant la position avec une précision supérieure au 1/100e de millimètre ;
— le dispositif de compensation automatique de la force subie par l'échantillon.
Il est en outre prévu d'adapter l'appareil pour effectuer des mesures aux basses et aux hautes températures.

On a procédé par dilution isotopique au dosage du lithium dans 76 échantillons de laves représentant la quasi-totalité des formations éruptives du volcan du Mont Dore.
Les teneurs observées semblent indiquer que le lithium n'est associé qu'à la biotite, les autres minéraux magnésiens ne montrant aucun enrichissement. Le groupe des phonolites est dissocié de celui des ordanchites, et les rhyolites ne se placent pas sur une courbe de différenciation progressive.
Contribution à l'étude de la liaison hydrogène dans quelques chlorhydrates d'amines
Authors: Genêt Françoise 
Published: November 2018

Quatre chlorhydrates d'aminés tertiaires simples aliphatiques et aromatiques ont été étudiés par analyse radiocristallographique pour mettre en évidence l'influence de la nature des radicaux liés à l'atome d'azote sur la longueur des liaisons hydrogène.
— Dans le chlorhydrate de triéthylamine, on trouve une seule liaison hydrogène N...H...Cl de longueur 3,11 Å ; la structure cristalline qui présente un désordre est formée par l'assemblage d'éléments structuraux composés d'une molécule organique et d'une molécule d'acide chlorhydrique ; la cohésion entre ces molécules est assurée par liaison hydrogène.
— Dans le chlorhydrate d'isoquinoléine monoclinique, l'unique liaison N... H... Cl a pour longueur 2,92 Å ; on trouve qu'on a comme précédemment formation d'éléments structuraux indépendants.
— Dans le bichlorhydrate de 3-picolylamine : trois liaisons sont issues de l'atome d'azote à fonction primaire (3,11 Å, 3,16 Å, 3,20 Å), une seule de l'atome d'azote à fonction amine tertiaire (3,05 Å). La structure est composée d'un assemblage de chaînes formées par liaison hydrogène.
— Dans le chlorhydrate d'isoquinoléine triclinique, on trouve deux types de liaisons hydrogène dont une seule liaison issue de l'atome d'azote (3,00 Å).
La comparaison de ces résultats a permis de montrer que le nombre et la longueur des liaisons hydrogène issues de l'atome dépendent du nombre total d'atomes d'hydrogène qui y sont liés (atomes de la fonction amine et atome apporté par la molécule d'acide chlorhydrique).

ObjectiveStudies on the epidemiology of uveitis are rare and cohorts are small. We analyzed the frequencies of classified forms of uveitis in all patients at our center.MethodsWe studied 1916 consecutive patients with inflammatory eye disease. Data were analyzed regarding associated systemic disease, infection, ocular syndromes, anatomic localization, age, and sex.ResultsIn 59.1% of patients, a classified form of uveitis was observed: associated systemic diseases in 43.7%, the most frequent ones sarcoidosis (17.4%) and ankylosing spondylitis (16.8%); ocular syndromes in 34.3%, the most frequent HLA-B27-positive anterior uveitis (AU; 35.1%) and Fuchs uveitis syndrome (FUS; 34.3%); and infections in 22.4%, the most frequent herpetic infections (46.1%) and toxoplasmosis (31.5%). We found AU in 45.4% of patients (15.4% HLA-B27-positive AU and 11.3% FUS), intermediate uveitis in 22.9% (unclassified 53.7% and multiple sclerosis 10.3%), and posterior uveitis in 13.5% (24.7% toxoplasmosis). Panuveitis was diagnosed in 6.2% of cases (Behçet’s disease 12.6%; sarcoidosis 10.9%). The remaining 12.0% of cases showed extrauveal manifestations (scleritis, episcleritis, keratitis, optic neuritis, myositis, and orbital inflammation).ConclusionWe describe the largest cohort to date of consecutive patients from a specialized uveitis center. The high frequency of classified disease, nearly 60% in our clinic, shows the usefulness of an interdisciplinary approach, oriented on anatomic presentation.
The Terezita Romo Papers: Capturing the Spirit of Collective Action in Archives
Authors: Ulinskas Moriah 
Published: November 2018

This article addresses the Terezita Romo Papers, one of a handful of archival collections of the Royal Chicano Air Force—a large collective of young, mostly immigrant or first-generation Mexican American artists and activists who produced countless community events and art projects and programs in Sacramento, California during the second half of the twentieth century. While membership of the Royal Chicano Air Force (RCAF) and its activities are hard to calculate, its history has been shaped by a tendency towards iconization of the group’s male founders in archival description. Specifically, where collections are described to highlight the unique contributions of individuals, it is difficult to retain and promote the collective voice of action which made so many of these movements successful. Using the papers of Tere Romo, one member of the RCAF, this paper looks at how the archives of the RCAF have tended towards iconization—overshadowing the contributions of its female members—and explores ways in which archivists can reconsider the language of archives when processing and describing materials documenting collective action in American history.

A pena de morte na Ditadura Civil-Militar brasileira: uma análise processual
Authors: Abal Felipe Cittolin , Reckziegel Ana Luiza Setti 
Published: November 2018

O presente artigo trata a respeito da pena de morte durante a ditadura militar brasileira a partir de dois casos julgados pela justiça militar, durante esse período, em que os réus foram condenados à morte por sua participação no assassinato de um tenente do exército durante a guerrilha no Vale do Ribeira. Os acusados, membros da Vanguarda Popular Revolucionária, foram presos, torturados e julgados pela justiça militar, sendo condenados à morte. Tal sentença acabou sendo revertida posteriormente, porém trata-se de casos emblemáticos em que é possível verificar a parcialidade dos tribunais militares e o tratamento dado às pessoas tidas como subversivas pelo regime.

Does (Biasing) Nonverbal Information Deteriorate the Accuracy of the Take‐the‐Best Heuristic for Deception Detection?
Authors: Lob Aaron Benjamin , Chakir Nisrin , van Munster van Heuven Laurine , Verschuere Bruno 
Published: November 2024

ABSTRACTPeople are poor lie detectors, partly because they hold false beliefs about nonverbal cues to deception. Here, we investigated if guiding people to rely only on a message's detailedness (“take‐the‐best”) boosts their lie detection and to what extent such heuristic judgments are immune to nonverbal information. In three studies (Ns = 109, 88 and 144), participants made detailedness‐based veracity judgements, of text versus video statements (Study 1), or of statements without or with biasing nonverbal behavior (truth tellers diverting, liars maintaining gaze; Studies 2 and 3). Compared to unguided judgements, participants using the heuristic method achieved higher deception detection accuracy throughout. Mere access to nonverbal behavior did not deteriorate performance (Study 1), but the heuristic was not fully immune to biasing nonverbal behavior (Studies 2, 3). Our findings challenge the lay notion that access to nonverbal behavior benefits deception detection and suggest that only focusing on diagnostic cues improves lie detection.

AbstractA hydrogel that is expected as a biomedical load‐bearing material remains a substantial challenge. In this work, a multi‐solvent‐induced gradient aggregation state strategy is developed to construct lignin‐based supramolecular hydrogels that feature superstrong, tough, stretchable, and fatigue‐resistant properties. The multi‐solvent high‐temperature annealing induces the gradient crystallization of polyvinyl alcohol and the self‐assembly of lignin. The interior strong hydrogen‐binding and the external weak non‐covalent‐binding forms a gradient aggregation state microstructure and compact macrostructure, where lignin acts as an interfacial molecular bridge. By sharing interconnection points to collaboratively dissipate energy, the developed hydrogels demonstrate high modulus (74.4 MPa), toughness (90 MJ m−3), tear (34,000 J m−2), tensile (24.8 MPa), and compressive strength (60 MPa). Moreover, such lignin‐based supramolecular hydrogels also exhibit extraordinary fatigue resistance, biocompatibility, and reactive oxygen species scavenging activity. This gradient non‐covalent conjoined‐network caused by multi‐solvent high‐temperature annealing provides a new design strategy and potential for developing biomaterials that mimic biomedical load‐bearing materials (e.g., natural tendons and ligaments).
Coupling Solvation Structure Regulation and Interface Engineering via Reverse Micelle Strategy Toward Highly Stable Zn Metal Anode

Published: November 2024

AbstractThe stability of aqueous Z inc (Zn) ion energy storage devices is significantly compromised by the instability at the electrode/electrolyte interface, which can result in the growth of Zn dendrites, self‐corrosion, and various other side reactions. Regulating the Zn‐ion （Zn2+) solvation structure through electrolyte additives has been proved to be effective strategy in stabilizing the Zn anode, but the influence of free water on the solvation structure is often lacking in‐depth exploration. Herein, the piperazine‐N,N‐bis(2‐hydroxypropanesulfonic acid) sodium salt (POPSO‐Na) is presented as a multifunctional electrolyte additive, which enhances the stability of the Zn anode by modulating the deposition and stripping environment of Zn2⁺ and limiting the presence of free water in the electrolyte during cycling. Theoretical calculation and experimental results demonstrate that the POPSO‐Na additive can not only replace the structural water around Zn2+ to destroy the original solvation sheath, but also form reverse micelle interface structure to hinder the proton transition and constrain the free water in the electrolyte. Thus, the Zn||Zn battery utilizing the ZnSO4+POPSO‐Na electrolyte exhibits an impressive cycle life of 1600 h at a current density of 1 mA cm−2, achieving an average Coulomb efficiency (CE) of ≈100%, which is significantly better than that observed with the ZnSO4 electrolyte. Moreover, the Zn||Cu battery with ZnSO4+POPSO‐Na electrolyte achieves high stability even after cycling for over 2000 h.
Modulation on Surface Termination Groups to Optimize the Adsorption Energy and Work Function of Nb2CTx for Enhanced Hydrogen Storage in Magnesium Hydride

Published: November 2024

AbstractExploring high‐performance catalysts for hydrogen storage in magnesium hydride (MgH2) is crucial but still a challenge. Herein, Nb2CTx with controllable surface termination groups is developed as an efficient catalyst and the bifunctional modulation (adsorption energy and work function) of different surface termination groups (F, O, OH, or defects) is explored. First, compared to F and O, the introduction of OH on the surface or the direct removal of functional groups both leads to a significant increase in the adsorption of H by Nb2CTx. Second, compared to the surface bare, OH‐rich Nb2CTx has a lower work function, making it easier for hydrogen to enter Mg/MgH2 from the Nb2CTx surface or escape from the Mg/MgH2 surface into the Nb2CTx, thus facilitating the hydrogen ad/desorption properties of MgH2, i.e., the rate‐determining step (RDS) shifts from penetration to diffusion. The Nb2CTx‐KOH‐catalyzed MgH2 with optimal surface termination groups, therefore exhibits a release of 6.56 wt.% H2 in 5 min at 250 °C, and 6.46 wt.% H2 uptake within 5 min at 150 °C. The dehydrogenation and hydrogen uptake activation energies show 49.5% and 60.1% enhancements over pristine MgH2. In addition, a storage capacity of 5.51 wt.% is maintained after 50 dehydrogenation/hydrogenation cycles.

AbstractThe transition metal dichalcogenide 1T‐TaS2 exhibits a Charge Density Wave (CDW) with in‐plane chirality. Due to the rich phase diagram, the Ferro‐Rotational Order (FRO) can be tuned by external stimuli. The FRO is studied by Angle‐Resolved Photoelectron Spectroscopy (ARPES), Raman spectroscopy, and Selected Area Electron Diffraction (SAED). The in‐plane chirality of the CDW is lost at the transition from Nearly‐Commensurate (NC) to In‐Commensurate (IC) phase and can be controlled by applying shear stress to the sample while cooling it through the transition from IC‐CDW to NC‐CDW. Based on these observations, a protocol is proposed to achieve reliable, non‐volatile state switching of the FRO configuration in 1T‐TaS2 bulk crystals. These results pave the way for new functional devices in which in‐plane chirality can be set on demand.
