This study evaluates the impact of sales promotions that are featured in store flyers distributed by prominent retailers and their capacity to attract consumers to their establishments. A distinctive conceptual framework is introduced that scrutinizes the influence of ethically-minded consumer behavior, digital citizenship/literacy, and a retailer's orientation toward environmental sustainability and explicit ecological concerns. A quasi-experimental design was used to formulate four distinct scenarios from a possible set of eight, stemming from the combinations of three variables: 2 Retailer Positioning (green vs. without explicit ecological claims) × 2 Flyer Mediums (paper vs. digital) × 2 Discount Levels (5% discount vs. 30% discount). Through an online survey, a sample of 269 responses was garnered to gauge consumer reactions to these store flyers, evaluating their attitudes and receptiveness. The findings suggest that attitudes toward paper flyers were more favorable when presented by non-green retailers compared to their green counterparts. This can be attributed to a perceived inconsistency between a green brand positioning and the use of paper flyers. Furthermore, the propensity to transition to digital flyers was notably stronger for green retailers compared to non-green retailers, but this inclination was most pronounced when higher discounts were offered.

The pulp and paper industry stands out as an example of a technology based on a renewable resource, cellulose. The sludge, however, poses major environmental and public health problems. To effectively manage the sludge wastes, it is critical to fully evaluate its composition, possible environmental impacts, and the total amount of exploitable renewable resources. The study established the pH of the sludge to be 7.32 ± 0.98, an electrical conductivity (1.84 mS/cm), nitrogen concentration (2.65 ± 0.21%), and total organic matter (41.23 ± 3.11%). The cellulosic content was established to be 74.07 ± 2.71% which contributes to 53.07 ± 1.23% water holding capacity (WHC). The most abundant elements were C and O, followed by Cl, Si, Al, and Mg, with lower concentrations of S, Si, K, and iron. The polycyclic aromatic compounds (PAHs) levels ranged from 0.29 to 322.56 ng.g-1 with 1-methyl pyrene posting the highest concentration (322.56 ng.g-1. XRD peaks at 17.10°, 23.86°, 30.14°, and 36.57°, which imply the existence of CaCO3. SEM indicated that the sludge was majorly comprised of fibers materials with average particle sizes of 280 micrometers. TGA/DTG analysis showed that the sludge had the greatest cellulose and hemicellulose (64.7 wt. %). [ABSTRACT FROM AUTHOR]

For many centuries, paper is the main material for recording cultural achievements all over the world. Infrared (IR) spectroscopy is an essential analytical tool for the structural analysis of paper and pulp chemistry. This review article introduced recent technical and scientific reports in terms of IR spectroscopy in the paper science and application, where interest had increased during the last couple decades (2000–2022). Five parts were described according to the application of IR spectroscopy: the analysis of cellulose and its derivatives, estimation the date of documents, identification the origins of fiber or paper, specification the chemical and physical properties of paper, and characterization the new materials of paper.

Cellulose was isolated from recycled pulp and paper sludge and used to synthesize cellulose nanocrystals. Response surface methodology and Box-Behnken design model were used to predict, improve, and optimize the cellulose isolation process. The optimal conditions were a reaction temperature of 87.5 °C, 180 min with 4% sodium hydroxide. SEM and TEM results revealed that the isolated cellulose had long rod-like structures of different dimensions than CNCs with short rod-like structures. The crystallinity index from XRD significantly increased from 41.33%, 63.7%, and 75.6% for Kimberly mill pulp sludge (KMRPPS), chemically purified cellulose and cellulose nanocrystals, respectively. The TGA/DTG analysis showed that the isolated cellulosic materials possessed higher thermal stability. FTIR analysis suggested that the chemical structures of cellulose and CNCs were modified by chemical treatment. The cellulose surface was highly hydrophilic compared to the CNCs based on the high water holding capacity of 65.31 ± 0.98% and 83.14 ± 1.22%, respectively. The synthesized cellulosic materials portrayed excellent properties for high-end industrial applications like biomedical engineering, advanced materials, nanotechnology, sustainable packaging, personal care products, environmental remediation, additive manufacturing, etc. [ABSTRACT FROM AUTHOR]

During the early Cold War, it was difficult for American intelligence to penetrate the Iron Curtain but a potential solution soon arose: émigré intelligence groups such as the Magyar Harcosok Bajtársi Közössége (MHBK) or 'Association of Hungarian Veterans'. This group, however, turned out to be an intelligence 'paper mill'. Attempts at trans-Atlantic cooperation with the MHBK and similar groups failed as they lost most of their good sources and were penetrated by communist security services. By the mid-1950s, US intelligence cut these groups off, took over their good sources, and established a source registry to prevent recurrence of the problem. [ABSTRACT FROM AUTHOR]

Thiophene sulfide is difficult to be removed by hydrodesulfurization. In this study, ZnCl2-waste paper fiber activated carbon was used as adsorbent to remove thiophene sulfide from simulated oil by hydrothermal modification. Under the optimum condition of ammonia modification, the adsorption capacity of modified adsorbent to BT is 14.8 mg S/g, 2.98 times that of unmodified. BET, FTIR and Boehm analysis showed that the mesopore volume of ammonia modified adsorbent increased by 96.62% and the mesopore ratio increased from 12.58% to 43.40%, which was conducive to improving the adsorption rate. After modification, the basic groups on the surface of the adsorbent increased by 44.3 times, and –NH3+, –OH and –NH2 enhanced the electron attraction and hydrogen bonding force between the adsorbent and BT molecule. Adsorption isotherms, adsorption kinetics and adsorption thermodynamics show that the adsorption process is spontaneous, entropic and exothermic. The pseudo-second-order kinetic rate constant increases with the increase of adsorption temperature, indicating that the increase of temperature is beneficial to accelerate the adsorption rate. The adsorption desulfurization process follows the mechanism of single and multilayer adsorption mixing. The results of this study can help to reveal more clearly that biobased activated carbon can be modified to adsorb thiophene sulfide. Ammonia modified adsorbents enhance the adsorption capacity for benzothiophene [ABSTRACT FROM AUTHOR]

This article introduces a flexible and easy-to-implement open-ended scientific inquiry activity called the Paper Towels Challenge. After experimentally determining which of three unbranded paper towels is the most absorbent, students discuss their results and methods. The teacher facilitates the discussion of epistemological issues. This activity can be used regardless of the participants' age or country to promote science understanding, NGSS science and engineering practices, and twenty-first century skills, such as critical thinking and communication. The many uses, benefits, and possible adaptations of the activity are discussed. [ABSTRACT FROM AUTHOR]

Iron-impregnated filter paper (Fe-Pi) was evaluated as phosphorus (P) extractant in four soils of Ogun state, southwest Nigeria in a screenhouse experiment. The experiments lasted for 8 weeks. Soil P contents were extracted at 0, 4, and 8 weeks after the incorporation of amendments (cattle manure, poultry manure, and wood ash) using Fe-Pi, Bray-1, Bray-2, Mehlich-1, Hunter, and Olsen extractant. Agronomic variables were taken fortnightly from grown maize plants and later harvested at 8 weeks, residual effects of the treatments were also evaluated. Maize dry matter weight (DMW) and P uptake were also measured. Results indicated that a linear relationship existed among the extractants with significant coefficient at p ≤.001. Fe-Pi established a strong relationship with the conventional extractants in the following order: Bray-1 (R2 = 0.99) > Bray-2 (R2 = 0.98) > Hunter (R2 = 0.96) > Mehlich-1 (R2 = 0.86) > Olsen (R2 = 0.82). Fe-Pi had a significant relationship with P uptake and DMW. Phosphorus uptakes under the animal manure amendments were statistically higher than uptake in control and woodash amended soils. Therefore, the study concluded that Fe-Pi was a good predictor of plant available P and had significant relationship with Bray-1, thus it could be considered for the estimation of soil available P in soils of southwest Nigeria.

Xuan paper is one of the most famous handmade papers in China and is an important paper for conservation. However, the evenness of Xuan paper has not yet received much attention. In this study, the distribution of the in-plane grammage and mechanical properties of Xuan paper are measured. It is found that the distribution of the in-plane grammage and mechanical properties of Xuan paper is uneven. In the handmade direction, the grammage and mechanical properties of Xuan paper are overall largest in the lower area, followed by the upper and middle areas. The sheet forming process of Xuan paper has an important effect on the distribution of in-plane grammage, mechanical properties, and fiber orientation of Xuan paper. The folded state has a negative effect on the mechanical properties of the folded area of Xuan paper. This study will help raise awareness of the unevenness in physical properties of Xuan paper, which is important in both conservation and research applications. [ABSTRACT FROM AUTHOR]
