Hornification in Commercial Chemical Pulps: Dependence on Water Removal and Hornification Mechanisms

Understanding cellulose hornification provides crucial information regarding drying of pulp, paper, and other cellulosic materials as well as recycling them. By measuring drainage, fiber width, and water retention value of hardwood and soft...

Triple‐State Invisible Photonic Crystal Pattern Encrypted in Hollow‐Silica/Polyurethane Film for Anticounterfeiting Applications

An invisible photonic crystal (PC) pattern encrypted at the dry state and decrypted by solvent is a new anticounterfeiting material system, but its diversity and complexity in response are still required to be increased to enhance the antic...

Color Space Transformation-Based Algorithm for Evaluation of Thermochromic Behavior of Cholesteric Liquid Crystals Using Polarized Light Microscopy

Preparation of Solid Superacid SO42-/ZnO-TiO2 and Its Action on Synthesis of Dimethyl Carbonate from Urea and Methanol

SO42-/ZnO-TiO2 catalyst was prepared by sulfating ZnO-TiO2 powders with H2SO4 solution. The catalyst was characterized by XRD, IR and Hammett indicator. The catalyst showed strong acidity(H0 ≦-16.0). The optimum conditions are found that th...

Synthesis and Characterization of Four Random copolymers Containing Fluorene as Electron Donors and Benzotriazole, Benzothiadiazole, Pyrido[3,4-b]pyrazine as Electron Acceptors

Four copolymers, poly(fluorene-pyrido[3,4-b]pyrazine) (PFPP), poly(benzotriazole-fluorene-pyrido[3,4-b]pyrazine) (PBTFPP), poly(benzotriazole-fluorene-benzothiadiazole) (PBTFBD), poly(benzothiadiazole-fluorene-benzothiadiazole) (PBDFBD)were...

The Application of Electrospun Titania Nanofibers in Dye-sensitized Solar Cells

Titania nanofibers were fabricated using the industrial NanospiderTM technology. The preparative protocol was optimized by screening various precursor materials to get pure anatase nanofibers. Composite films were prepared by mixing a comme...

Advances and Prospects of China's Premium Deepwater Drilling and Production Equipment

China is now witnessing vigorous offshore exploration and development， corresponding to an increasing demand for localized offshore equipment. To achieve the goal of high-quality development of premium offshore drilling and production equip...

Leaching and recycling of NdFeB permanent magnets using ionic non-toxic hydrotropes instead of extractants

We show hereby that recycling of NdFeB permanent magnets by selective leaching and precipitation is possible, using an electrolyte as hydrotrope, thus avoiding the need of any specific extractant molecules. We analyse the yield of the extra...

Development of a Viscosity Measuring Device for Low Boiling Point Refrigerant Mixtures

According to the need for viscosity measurement of refrigerant mixtures, a new rotatable capillary viscometer is developed and designed. It is adequate for the viscosity investigation of the low boiling point liquid mixtures. A rotatable ca...

The Effect of Time on the Activation of Bayah Natural Zeolite for Application of Palm Oil Shell Pyrolysis

Oil palm shell (OPS) constitutes 60% of the waste generated during the processing of palm oil. However, OPS can potentially be converted into energy and chemicals through pyrolysis. The purpose of this study is to determine and analyse the ...

Socioeconomic Determinants of Sustainable Technology Adoption and Its Influence on Brazilian Agricultural GVP

Brazil’s agricultural sector is characterized by persistent productive duality: a technologically advanced export-oriented segment coexists with a large stratum of smallholders generating low economic returns. Understanding the economic det...

“Ligando as pontas!” - A atuação do Fundo Podáali no fomento da bioeconomia na Amazônia

Apesar de sua incontestável importância para a preservação da biodiversidade e para o combate às mudanças climáticas, a floresta amazônica está passando por um alarmante processo de destruição. Com índices de preservação muito acima da médi...

Are the firms’ capital structure and performance related? Evidence from GCC economies

AbstractThis study examines the empirical relationship between the different leverage levels as a proxy of financing mix on the financial performance of the non-financial firms listed on capital markets in GCC economies. The study uses the ...

Melatonin: dual players mitigating drought-induced stress in tomatoes via modulation of phytohormones and antioxidant signaling cascades

Abstract Drought stress significantly retards the plant production. Melatonin is a vital hormone, signaling molecule, and bio-regulator of diverse physiological growth and development processes. Its role in boosting agronomic traits under d...

Synopsis of Dendrophthora and Phoradendron (Santalaceae) in Brazil

Abstract Dendrophthora and Phoradendron are neotropical genera of mistletoes belonging to the tribe Phoradendreae. The phylogenetic relationships between these two genera are still not entirely understood and, morphologically, Dendrophthora...

BIOLOGICAL ASPECTS AND THERMAL REQUIREMENTS OF THE BIRD CHERRY-OAT APHID, Rhopalosiphum padi (LINNAEUS), REARED ON WHEAT SEEDLINGS

The bird cherry-oat aphid, Rhopalosiphum padi (Linnaeus) was studied at 15, 20 and 25oC constant temperatures. Wheat seedlings were offered for feeding and maintaining the aphid, R. padi using the Punctured Ependorf Tube Technique. R. padi ...
