Host–Guest Interactions Govern Drug Stability and Controlled Therapeutic Release: Based on Metal–Organic Frameworks as Smart Platforms

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Due to their exceptional porosity, structural versatility, and modular coordination chemistry, metal–organic frameworks (MOFs) have emerged as versatile platforms for targeted drug delivery. These structures enable fine‐tuning of pore size, surface activity, and framework stability for the encapsulation of a broad range of therapeutics ...

Strength–Ductility Enhancement in Additively Manufactured Titanium Alloys via Neutral Element‐Mediated Microstructural Control

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT To overcome the challenges of the strength‐ductility trade‐off in laser additively manufactured (LAM) titanium alloys, and to avoid the intragranular microstructure degradation often caused by an exclusive focus on grain equiaxialization, this work proposes a novel strategy of “grain morphology‐intragranular microstructure co‐optimization ...

Synergistic Enhancement of Strength and Creep Resistance in Additive Manufacturing Ti‐6.5Al‐2Zr‐Mo‐V Alloy via In Situ Co‐Modification With Si and Y Elements

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The demand for advanced aerospace components necessitates near‐α titanium alloys with enhanced high‐temperature performance and compatibility with additive manufacturing (AM). To address this, an in situ alloying strategy was employed to co‐modify a Ti‐6.5Al‐2Zr‐Mo‐V alloy with Si and Y during laser powder bed fusion.

Multimodal Deep Learning‐Assisted Microstructural Evaluation System for Sintered NdFeB Magnets

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The performance of sintered NdFeB magnets, especially coercivity, is critically determined by their complex microstructure. However, a quantitative microstructural evaluation system (MES) is much needed but has long been missing in the community.

煤矸石对盐碱土壤绿化和土壤微生物的影响

open access: yesShuitu Baochi Xuebao, 2018
为探究煤矸石对盐碱土壤绿化的改良效果和对土壤微生物的影响,将不同用量(0,10%,20%,30%,40%,50%)和不同粒径(小粒径5 mm,以及小中大粒径等比例的混合粒径)煤矸石施用于盐碱土壤,进行紫花苜蓿盆栽试验,测定紫花苜蓿株高、生物量以及土壤微生物量和酶活性指标。结果表明,不同粒径煤矸石处理的土壤微生物量碳氮,土壤的脲酶、过氧化氢酶、脱氢酶活性,以及紫花苜蓿株高、生物量均随着煤矸石用量的增加呈先增大后降低的趋势,混合粒径、小粒径、中粒径、大粒径煤矸石处理的盐碱土上述指标分别在20%,20%,30%

Epitaxial Growth Mechanism and Magnetic Properties of Heterogeneous Core–Shell Grains in (Nd, Y)‐Fe‐B Alloys

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The construction of core–shell grains can enhance the coercivity of Nd2Fe14B magnets. However, it is a significant challenge to elucidate the formation of these core–shell grains particularly regarding the spontaneous core–shell structure in Y‐substituted Nd2Fe14B alloys.

Synergy of Strength and Plasticity in Extruded VZ91K Magnesium Alloy Achieved by Constructing Bimodal Grain Structure via Suppression of PSN‐DRX

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Bimodal grain structure (BGS) demonstrates significant potential in synergistically optimizing the strength and plasticity of magnesium alloys. Acquiring the desired BGS consequently became a critical challenge. This study took the Mg‐9Gd‐1Zn‐0.5Zr (wt%, VZ91K) alloy as its subject. From the perspective of BGS formation mechanisms, it suggests

Breaking Shuttle‐Induced Kinetics Limitations in Lithium–Sulfur Batteries: Confined FeS2 Nanocatalyst With Optimized d‐Band Center

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The commercialization of lithium‐sulfur batteries (LSBs) faces dual challenges of sluggish sulfur redox kinetics and lithium polysulfides (LiPSs) shuttling. Herein, we demonstrate a synergistic strategy combining multidimensional structural confinement with d‐band center modulation to simultaneously suppress LiPSs diffusion and catalyze ...

浊度法用于测量悬浮液中微量固体颗粒浓度

open access: yesGongye shui chuli, 2008
采用浊度法检测含有微量细小的分子筛颗粒和金属镍颗粒的悬浮液中微量固体颗粒浓度,并对相关因素的影响进行了研究。结果表明:在实验范围内,悬浮液微细颗粒的浓度与悬浮液浊度成线性关系;对微细颗粒悬浮液,采用d32(Sauter直径)作为平均直径比采用中位直径d50更能反应出粒径因素对浊度的影响。
