山东玻纤: 山东玻纤集团股份有限公司关于上海证券交易所《关于公司2024年年度报告的信息披露监管问询函》的回复公告
Zheng Quan Zhi Xing· 2025-06-20 12:07
Core Viewpoint - The company, Shandong Fiberglass Group Co., Ltd., reported a decline in revenue and a shift to net losses in 2024, primarily due to decreased sales prices and volumes in the fiberglass sector, amidst an oversupplied market [1][6][7]. Financial Performance - In 2024, the company achieved operating revenue of 2.006 billion yuan, a year-on-year decrease of 8.89% [1]. - The net profit attributable to shareholders was -99 million yuan, a significant decline from the previous year [1][7]. - The cash flow from operating activities was 162 million yuan, down 70.40% year-on-year, mainly due to increased cash payments for goods and services [1]. Customer and Supplier Information - The company disclosed its major customers and suppliers, indicating stable operations with normal payment terms [2][3]. - Key customers included Shanghai Songou New Materials Co., Ltd. and Guangzhou Bangju New Materials Co., Ltd., with sales revenues of 65.18 million yuan and 50.30 million yuan, respectively [2]. Industry Context - The fiberglass industry in China is experiencing overcapacity, with production capacity reaching 6.7 million tons and total output at 7.23 million tons by the end of 2023 [6]. - The average selling price of fiberglass yarn decreased by 225.64 yuan per ton in 2024, contributing to revenue loss [6][20]. - The market for fiberglass remains competitive, particularly in low-end products, while high-end applications like wind energy are expected to grow [6][18]. Cost Structure and Profitability - The cost structure for fiberglass yarn in 2024 showed direct materials accounting for 39.45% and energy costs for 23.60% [8]. - The decline in profitability was attributed to both lower sales prices and reduced sales volumes, with a total sales volume of 443,300 tons in 2024, down 8.09% from 2023 [20].

新研究有望突破传统探针尺寸对分辨率的限制

来源:中国科学报 中国科学讯厦门大学柔性电子(未来技术)研究院教授梁亮亮团队联合新加坡国立大学教授刘小钢团 队,在镧系元素掺杂光子雪崩上转换纳米晶研究中取得进展。相关研究成果6月18日发表于《自然》。 光子雪崩是镧系掺杂材料中的一种独特光学非线性现象,能量正反馈循环过程使其发光强度与泵浦功率 表现出极其陡峭的幂律关系,使得极微弱的泵浦扰动或环境变化也能诱发发光强度的显著突变。凭借这 一特性,光子雪崩在低成本超分辨成像、超灵敏光学传感和多物理场探测等应用中展现出巨大潜力。 研究结果表明,以离子半径更小、原子质量更大的Lu3+离子替代Y3+离子,可有效调控晶体内空位与离 子的排布倾向并引入局部晶体场畸变,从而有效加速光子雪崩过程中的交叉弛豫过程。该策略使得27纳 米颗粒的光学非线性提升至156,雪崩响应时间显著缩短至8.5毫秒,缩短为传统核壳结构纳米晶的近 1/70,展现出优异的快速响应特性。在单束连续波激光扫描成像系统中,该材料实现了横向33纳米(约 为波长的1/33)、轴向80纳米(约为波长的1/13)的空间分辨率,成像信噪比大于20,定位精度高达 0.36纳米,展示出在低成本超分辨成像方面的应用潜力。 此外 ...
