Research ArticleOpen accessEvery word in the titlePREPARATION OF ACTIVATED CARBON FROM PALM OIL SHELL BY CHEMICAL ACTIVATION WITH Na2CO3 AND ZnCl2 AS IMPRENATED AGENTS FOR H2S ADSORPTIONKanokorn HussaroHydrogen Sulfide (H2S, rotten-egg) is one of the major environmental pollutants having its sources in natural and anthropogenic activities. It’s had smell gas produced by anaerobic digestion in acid condition from organic and inorganic compounds containing sulphur, presents dual problems of its toxicity and foul ordour. One of methods of its removal is adsorption. Activated carbon is a widely used … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 17 Jun 2014 · 8,480 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Quantum Mechanical Study of Structural and Electronic Dilution Effects in Paramagnetic Chemical Exchange Saturation Transfer AgentsWhelton A. Miller III, Preston B. MooreWe present a computational study of the effect of chemical modifications of the meta and para substituents in the coordinating pendant arm of a modified 1,4,7,10-tetraazacyclododecane-N, N’, N’’, N’’’-tetraamide (DOTAM) ligand on the Chemical Exchange Saturation Transfer (CEST) signal. Magnetic Resonance Imaging (MRI) is currently one of the most widely used techniques available.

Research ArticleOpen accessIn the keywordsINCREASING ADSORPTION OF ACTIVATED CARBON FROM PALM OIL SHELL FOR ADSORB H2S FROM BIOGAS PRODUCTION BY IMPREGNATIONWasan Phooratsamee, Kanokorn Hussaro, Sombat Teekasap, Jongjit HirunlabhBiogas is the combustible gas produced through a biological process, known as anaerobic digestion which is the process operated at low-temperature and without air. Biogas consists of 55-80% CH4, 20-45% CO2 with trace amount of H2S and other impurities. Common H2S removal technologies from biogas fall into one of adsorption on a solid such as iron oxide based materials, activated … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 16 Aug 2014 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluence of Triethanolamine on the Chemical Bath Deposited NiS Thin FilmsAnuar Kassim, Ho Soon Min, Tan Wee Tee, Ngai Chee FeiProblem statement: Recently, many scientists looking for new chalcogenide materials for the solar cell applications. Nowadays, silicon-based solar cell became dominant products in the market. Because of expensive silicon-based solar cells, scientists hope replaces it with cheaper chalcogenide materials. Approach: The binary chalcogenide materials were deposited onto microscope glass slide using simple chemical bath deposition method. Here, we study the … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,970 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Diversity as a Biological Control Mechanism for Fruit Tree Diseases: A Comparative ApproachZhichao TangThe traditional methods of fruit tree pest control have long relied on chemical pesticides. This not only leads to increased resistance of pests and diseases but also adversely affects the ecological environment and fruit safety. Although biological control has gradually received attention, the current research on how to systematically use microbial diversity to achieve efficient control and prevention is still … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 8 Apr 2026 · 1,603 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcaricidal Activity of Azadirachta indica (Neem Tree) and Carica papaya (Papaya) Leaf Extracts against Rhipicephalus sanguineus (Dog Ticks) Using Spray MethodAlfredo Vita Corpuz, Carmela Montoya Florentino, Paul Erman Tabuloc Quilana et al.Ticks pose a serious threat to dogs, with synthetic acaricides leading to environmental impact and resistance concerns. While Azadirachta indica and Carica papaya have shown acaricidal potential against Rhipicephalus sanguineus, their efficacy against dog ticks has not been thoroughly investigated.
