The Material Basis of 18th‐Century Meissen Porcelain

open access: yesArchaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Success and failure in England's patent system: New evidence from patent applications, 1783–1834

open access: yesThe Economic History Review, EarlyView.
Abstract Our understanding of the relationship between the English patent system and technical change during the industrial revolution is based entirely on the study of successful patents. We address this feature by providing the first study of unsuccessful patent applications in England during the first industrial revolution.

Winter Natural Evaporation Experiment of Deep Brine With Sand‐Gravel Pores in Da Lang Tan

open access: yesEngineering Reports, Volume 8, Issue 8, August 2026.
The deep sand gravel type pore brine in Qaidam Basin belongs to unsaturated chloride type brine with high calcium, high sodium and low potassium. A total of 600 kg of graveltypepore brine at 1000–2000 m underground in Dalangtan mining area, was selected for the test, and evaporated and crysta‐llized in the natural state in summer.

Liebig Review: Essential and Beneficial Elements in the Regulation of Cadmium Uptake and Tolerance in Crop Plants

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 429-444, August 2026.
ABSTRACT Cadmium (Cd2+) contamination in agricultural soils has been reported to pose risks to crop productivity, food safety, and human health. This review synthesizes current knowledge on the mechanisms by which essential (S, Zn, Fe, Mg, K, Ca) and beneficial (Si, Se, rare earth elements) elements mitigate Cd2+ toxicity in plants.

Natural Resources and Political Patronage in Africa: An Ethnicity Level Analysis

open access: yesReview of Development Economics, Volume 30, Issue 3, Page 1957-1972, August 2026.
ABSTRACT We investigate the effect of resource discoveries on ethnicity‐level political patronage in Africa using a large geospatial dataset of 254 ethnic groups in 15 countries over the period 1960–2004. We find that the first (or single first) resource discovery in a virgin ethnic homeland increases the share of cabinet posts of that ethnicity.
