Steel scale-CaO composite catalyst for coke combustion and in-situ NO and SO2 removal
Li Zhang,Jingchong Yan,Zhiping Lei,Xianzhong Cao,Tiejun Chun,Zhanku Li,Hengfu Shui,Shibiao Ren,Zhicai Wang,Ying Kong 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.110 No.-
The performance of the steel scale (SS)-CaO composite on the combustion of coke nuts and in-situ reductionof SO2 and NO emission was investigated. Combustion experiments show that SS-CaO compositeaccelerates coke combustion and reduces SO2 and NO emissions concurrently. X-ray diffraction (XRD),scanning electron microscopy (SEM), and electron spin resonance (ESR) were used to investigate thecatalysis mechanism. Results show that SS and CaO have synergistic effect in in-situ denitration. Theincrease of SS and CaO fraction in the composites improve the denitration and sulfur fixation performance,respectively. The denitration activity is mainly attributed to the Fe2O3 in SS and Ca2Fe2O5 formedduring combustion. The desulfurization is due to the sulfur fixation with CaO. The increasing fraction ofCaO in the composites leads to the agglomeration of ash particles. 2%CaO is confirmed as the optimumaddition for catalytic combustion and emission reduction. This work sheds light on the cheap and effectivecatalysts that are potentially useful for iron ore sintering.

Preparation and antimicrobial assay of ceramic brackets coated with TiO₂ thin films

Objective: Different methods have been utilized to prevent enamel demineralization and other complications during orthodontic treatment. However, none of these methods can offer long-lasting and effective prevention of orthodontic complications or interventions after complications occur. Considering the photocatalytic effect of TiO₂ on organic compounds, we hoped to synthesize a novel bracket with a TiO₂ thin film to develop a photocatalytic antimicrobial effect. Methods: The sol-gel dip coating method was used to prepare TiO₂ thin films on ceramic bracket surfaces. Twenty groups of samples were composed according to the experimental parameters. Crystalline structure and surface morphology were characterized by X-ray diffraction and scanning electron microscopy, respectively; film thickness was examined with a surface ellipsometer. The photocatalytic properties under ultraviolet (UV) light irradiation were analyzed by evaluating the degradation ratio of methylene blue (MB) at a certain time. Antibacterial activities of selected thin films were also tested against Lactobacillus acidophilus and Candida albicans . Results: Films with 5 coating layers annealed at 700°C showed the greatest photocatalytic activity in terms of MB decomposition under UV light irradiation. TiO₂ thin films with 5 coating layers annealed at 700°C exhibited the greatest antimicrobial activity under UV-A light irradiation. Conclusions: These results provide promising guidance in prevention of demineralization by increasing antimicrobial activities of film coated brackets.

Gene therapy with nonviral vectors using the suicide gene/prodrug activating system of herpes simplex virus type-1 thymidine kinase (HSV1-TK)/ganciclovir (GCV) is inefficient in killing malignant tumor cells due to two major factors: (a) an unsatisfactory bystander effect; (b) short-lived expression of the protein. To study the capacity of the protein transduction domain (PTD) of HIV-1 TAT protein to enhance HSV1-TK/GCV cancer gene therapy, we constructed three fusion proteins TAT-TK, TK-TAT and TK. TATTK retained as much enzyme activity as TK, whereas that of TK-TAT was much lower. TAT-TK can enter HepG2 cells and much of it is translocated to the nucleus. The transduced HepG2 cells are killed by exogenously added GCV and have bystander effects on untransduced HepG2 cells. Most importantly, the introduced recombinant protein is stable and remains functional for several days at least, probably because nuclear localization protects it from the cytoplasmic degradation machinery and provides access to the nuclear transcription machinery. Our results indicate that TAT fusion proteins traffic intercellularly and have enhanced stability and prodrug cell killing activity. We conclude that TAT has potential for enhancing enzyme prodrug treatment of liver cancers.
How Does Corporate Social Responsibility Affect Innovative Work Behaviour?
Viet Quoc Cao(Viet Quoc Cao ) People&Global Business Association 2023 Global Business and Finance Review Vol.28 No.4
Purpose: This research examines the effect of perceived corporate social responsibility on the employee-company relationship (organisational trust, organisational identification) and employees' future well-being and participation in innovative work practices. Design/methodology/approach: This study used a quantitative research approach by PLS-SEM analysis with a sample size of 400. The respondents are employees working for four distinct textile garment manufacturing enterprises in Vietnam. Findings: Our study found that corporate social responsibility directly impacts organisational trust, identification, well-being, and innovative work practices, and innovative work behaviours are directly related to organisational trust, employee well-being, and identification. Research limitations/implications: The study focuses on workers who have a basic understanding of corporate social responsibility. Consequently, the scope of research in diverse industries throughout the country's regions and cities must be expanded. Given the constraints, future studies should be broadened and conducted in greater detail. Each profession should concentrate its efforts on a broader range of survey subjects, such as office workers, employees, and consumers. Originality/value: Employee well-being is linked to innovative work behaviour, and the stronger the company's identity, the more likely people will be to be creative at work. The author found that people who work for a company that has a good sense of itself are more likely to be creative at work. The study shows that when employees are happy, they are more likely to work in new and innovative ways.
The effect of ancient Chinese philosophy on Chinese clothing culture
Cao, Zhenyu,Cao, Yuanqian The Costume Culture Association 2012 服飾文化硏究 Vol.20 No.5
Ancient Chinese philosophy has had a profound influence on Chinese clothing culture. The researchers reviewed five ancient Chinese philosophical thoughts on Chinese clothing culture. The results show that they had different view of point. The Confucianism advocated "being elegant and refined in manner". Dong Zhongshu believed "Interaction between heaven and mankind is the center of Dress rules". Mohist insisted "Clothing should meet warm first, and then seek for beauty ". Taoism believed "Although a gentleman wears coarse clothes, he has gem in his chest". Legalism believed "Clothing should focus on quality rather than decoration". These philosophy thoughts all have had a profound influence on Chinese clothing culture.
A Rare Tropical Stonefly Brahmana flavomarginata (Plecoptera: Perlidae: Acroneuriinae) from Vietnam
Cao, Thi Kim Thu,Bae, Yeon Jae The Korean Society of Systematic Zoology 2013 Animal Systematics, Evolution and Diversity Vol.29 No.2
The perlid stonefly Brahmana flavomarginata Wu, originally described from China from the male adult, is described using reared male and female adults and nymphs from Vietnam. The male adult of B. flavomarginata is distinguished from its congeners by the blackish-brown body color and distinct head marking, hemitergal triangular chitin plates, and a median semicircular smooth subgenital plate (hammer) on the abdominal sternum IX. The female adult has a large and round subgenital plate which extends to the posterior margin of the abdominal sternum X. The nymph can be distinguished by the relatively small compound eyes and the body covered by many long stout setae and short golden brown hair-like setae. This species is known in southwestern China (Yunnan Province) and northern Vietnam (Lao Cai Province, Cao Bang Province).
